Description

A kind of safety, one-time rice herbicidal composition and the control weeds in rice field Method
Technical field
Present invention relates in general to Pesticidal products, more particularly to a kind of herbicidal composition, preferably one Kind can be applied to the one-time rice herbicidal composition of direct seading rice and transplanting rice.The invention further relates to disposable using this The method that herbicidal composition controls weeds in rice field.
Background technology
From 2001 to 2025 year, in order to meet speed that population increases, global rice demand is estimated will to increase by 25%.With The reduction of resource, to be met in a manner of sustainable to rice increasing need, be one huge for us Challenge.Shortage and developing country labour urbanization of the reason in part for shortage of resources from available irrigation water, and these Country is also precisely the major producing country of rice.Because Direct-seeding Rice is without laborious transplanting process, and reduce the water demand of crop, So it substitutes transplanting rice with annual 1% increasing velocity in past 20 years.However, the weeds in direct seading rice field Prevent and kill off more much more difficult than transplanting rice field.
Weeds are a main contributors of the rice underproduction.According to estimates because the global rice underproduction caused by harmful organism is about 40%, the wherein underproduction possibility highest (32%) of weeds.The global rice underproduction accounts for total output caused by weeds according to estimates 10%.Ramzan points out that, because direct seading rice field weeds are more than transplanting rice field, the underproduction of Direct-seeding Rice is higher than transplanting rice (Ramzan M(2003)Evaluation of various planting methods in rice-wheat cropping systems,Punjab,Pakistan.Rice Crop Report 2003-2004,p.4-5).Obviously, a kind of effectively control is developed The method of weeds processed, become most important to keep up with the demand of rice.
Soil is substantially a huge Teaching practice base.Under suitable conditions, these seeds meeting sprout growth, with Rice competition sunlight, nutrient, space and moisture.Damp and hot Rice Cropping environment is particularly conducive to the breeding of weeds.Influence rice The weeds factor of yield includes species, the density of weeds and the opportunity of weed competition of weeds.The opportunity of weed competition refers to one Kind weeds cause the period of maximum effect to crop yield due to specific growth characteristics itself.Want to drop to production loss It is minimum, it is necessary to know the specific sprout time of weeds and remove its best opportunity.In addition, generally in direct sowing of rice or shifting Weeds are prevented and kill off in initial 40 days especially important after cultivation, because at this moment rice canopy is not yet grown up, can not be covered in straight It is mapped to soil surface and promotes the sunlight of weed growth.If the method without effective control weeds, weeds will grow fast than rice.
The opportunity that the significant challenge of all main weeds is above-mentioned weed competition is controlled with one-time use.For example, can Cause the rice underproduction to be up to 70% barnyard grass (Echinochloa crus-galli) needs to be prevented and kill off in paddy growth early stage, And the natural pond of the rice underproduction 21% is caused to give birth to different stamen flower (Heteranthera limosa), it is necessary to be removed in paddy growth mid-term.Add Herbicide itself applies hypsokinesis to (it loses activity quickly during being combined and/or being degraded with soil), therefore applies Herbicide is difficult to all work to all main weeds kinds within the whole rice cycle of typically for up to 110-160 days.
Chemical treatment is still one of control weeds most efficient method.However, so far, both without single herbicide Product, there is no one-time use method yet, main weeds all in rice field can be controlled.The reason for this is due to following：It is first First, the product containing single herbicide active ingredient can not individually control all main weeds, because a kind of effectively remove Careless agent is designed to special be combined with specific target receptor.Different weeds have different acceptors.Therefore, one kind is single has Imitate composition similarly can not combine with different acceptors.Second, not yet it has been reported that containing two or three of weeding active ingredient Product can prevent and kill off all main weeds because the rational mixture for realizing herbicide be one challenge.For example, cyhalofop-butyl (cyhalofop-butyl), a kind of efficient gramineous weed weedicide, when it and the mixing of other herbicides, either pre- Still antagonism is often produced in product processed in spraying in-tank mixing.3rd, it is generally deficient of granted mixed in aerosol can Operating guidance with different herbicide products, therefore, risk is undertaken by oneself completely when grower so does.Result is can not be pre- Material.For example, 2,4-D, it is a kind of effectively to prevent and kill off broad leaved weed and the herbicide of nutgrass flatsedge, such as in 15DAS and remove grassy weed Herbicide be administered simultaneously and can kill rice seedling, and conventional rice seedling when using 2,4-D is ripe at that time.4th, Ji Zhongzhu Weeds are wanted to generate resistance to herbicide, this reduces the validity that current Weeds distribution is applied.For example, it was reported that Barnyard grass has all generated resistance to nearly all conventional rice herbicide, and (azimsulfuron (azimsulfuron), benzyl is phonetic Sulphur is grand (bensulfuron-methyl), bispyribac-sodium (bispyribac-sodium), butachlor (butachlor), cyanogen fluorine Careless ester (cyhalofop-butyl) , fenoxaprops (fenoxaprop-P-ethyl), flucetosulfuron (flucetosulfuron), halosulfuronmethyl (halosulfuron-methyl), imazamox (imazamox), first imidazoles Nicotinic acid (imazapic), imazethapyr (imazethapyr), imazosulfuron (imazosulfuron) , metamifops (metamifop), molinate (molinate), penoxsuam (penoxsulam), clefoxidim (profoxydim), propanil (propanil), pyrazosulfuron (pyrazosulfuron-ethyl), pyribenzoxim (pyribenzoxim), KIH 6127 (pyriminobac-methyl), dichloro quinolinic acid (quinclorac), quizalofopPtefuryl (quizalofop-P-tefuryl), standing grain Careless pellet (thiobencarb)；Seewww.weedscience.org(International Survey of Herbicide Resistant Weeds))。
Therefore, Rice Cropping persons have no option now, repeatedly can only be made using a variety of herbicides to reduce weeds as far as possible Into Rice Yield Loss Caused.To understand a large amount of labours and the time that the multiple dispenser includes, it is noted that, such as and it is most of these Herbicide when closing before carrying out bud or after seedling cauline leaf dispenser, first must equally arrange the water in rice field before herbicide application Fall, wait 1-2 days again after dispenser, then introduce the water into rice field again.
Recent some books and paper have been disclosed for the method on how to control weeds in paddy field and suggestion, before 30 years Slightly improve.Its basic principle, such as plant before, before bud and after seedling processing, still and as before.For example, nearest one Publish within this 2014《Recent Advance in Weed Management》In book, author Chauhan, Bhagirath S., Mahajan, Gulshan suggest in Direct-seeding Rice use each seed bud before and herbicide after seedling because weeds are in extensive range And large number of (Recent Advances in Weed Management, Chauhan, Bhagirath S., Mahajan, Gulshan (Eds), 2014, Springer, ISBN978-1-4939-1019-9).Other disclosed documents are also illustrated in water The different time sections of rice growth need before different bud and herbicide after seedling (page 89, Chapter 7:Weed control in rainfed lowland rice,Kwesi Ampong-Nyarko and S.K.De Datta,A Handbook for Weed Control,1991,IRRI(ISBN 971-22-0020-5))。
To the greatest extent known to present inventor, still one was described without the information source of patent, publication, books and other document forms The independent rice herbicide product of kind, it is only necessary to apply once, it becomes possible to>90% preventive effect is to (especially live in rice terrace In rice terrace) all main weeds be controlled, holding effect up to 42 days or more long, and only slight rice drug misadventuring.Document Mainly around closing herbicide before the method-apply bud of traditional control weeds in paddy field, followed by second, sometimes the Herbicide is applied three times.Also no document describes the design of any this one-time rice herbicide products.The part of failure is former Because be rice main weeds-grass family, nutgrass flatsedge and broad leaved weed-the different periods respectively with rice carry out maximum journey The competition of degree, the conventional method mentioned before, it is the management for handling weeds in decentralized manner.
On the other hand, since 1991 FMC first by sulfentrazone (sulfentrazone) (Van Saun W.A.et Al.Proc.Br.Crop Prot.Conf-Weeds, 1991,1,77) since introducing market, itself and other companies (including DuPont, Tenkoz, Inc., Wilbur-Ellis and Bonide Products, Inc.) all produced containing sulfentrazone Herbicide products.However, mentioned and being used on rice without the label of any this product.In fact, each this product Label all warn：From last time applies the product at least ten moon, rice cultivation is unable in identical soil.This It is because for prior art, when before sulfentrazone product is used for bud or during early stage after seedling, unacceptable rice can be caused Poisoning.
Summary of the invention

According to the present invention, a kind of herbicidal composition has a variety of mechanism of action and to preventing and kill off moleplant seed (Leptochloa Chinensis) there may be synergistic effect.
In order to obtain to all main weeds>90% preventive effect and holding effect is long up to 42 days or more, our controlled release skill Art initial release first goes out enough herbicide active ingredient (such as sulfentrazone, penoxsuam He clomazone) to eradicate The weeds sprouted, then continue to discharge herbicide active ingredient in subsequent 40 days to provide lasting residual activity Persistently prevent new weed germination.
Our controlled release mechanism allow the upper soll layer in 0-1 inches keep highest herbicide concentration and it is long when Between be held in this.The region of upper soll layer 0-1 inches is the weeds sprouted, the weeds sprouted and will sprouted The main root area of weed seed, the region will not overlap (Fig. 1) with the main root area of deeper rice.This root system is deep The difference of degree is existing in dispenser, and difference becomes increasing within the rice cycle, therefore ensures from the beginning Poisoning to rice is minimum even without poisoning.Therefore, the present invention can introduce some originals can be dangerous but high to crop The active ingredient of effect.
First by sulfentrazone (PPO inhibitor classes herbicide), a kind of have efficiently but in administration before unacceptable The herbicide active ingredient of poisoning be safely introduced into rice.Different from other active ingredients, sulfentrazone not only can be effective Ground kills the nutgrass flatsedge sprouted and broad leaved weed, and for preventing most of weeds in all three main Types weeds Sprout and particularly effective.By the present invention, another PPO inhibitor class herbicide carfentrazoneethyl can also safely be drawn Enter in rice.The formula more thanH2O (carfentrazoneethyl product) safety,H2O has some strict limitations, agriculture The people seldom use it.Even in following strictlyH2During O labels, it can also cause serious rice leaf poisoning quickly, it is all Such as brown calcination spot, so as to reduce the efficiency of Rice Photosynthesis, it is grown and yield adversely affects.
The present invention selection introduce PPO inhibitor class herbicides as rice products partly because：(a) the present inventor The controlled formulation technique of maturation is developed, it can be by reducing or eliminating serious poisoning of the sulfentrazone to rice, finally Benefit from the high efficiency of sulfentrazone；PPO inhibitor class chemicals introducing rice field there are into some unique benefits (b).First, In the past few years, the weeds of resistance have been produced to herbicide substantially obtained to be resisted with PPO inhibitor class herbicides Popularization.Secondly, the weeds resistant to PPO inhibitor class herbicides are not common.With more and more to ALS suppression Agent class herbicide has produced the appearance of the weeds of resistance, and PPO inhibitor classes herbicide turns into the more preferable choosing for handling the problem One of select.
Clomazone is included in another active ingredient in the present invention.The , Yi Evil grass since FMC is commercialized Ketone has been approved for rice；However, due to its poisoning, its administration in global rice is limited, and it is often resulted in, and " rice is white Change or bleach "., clomazones can drift about what is worse, if surrounding has sensitive plant, cause its large area " albefaction ". Therefore seldom in China, a main Rice Production state applies , clomazones.Equally, the product containing clomazone3ME is also withdrawn from because of its unacceptable poisoning from Philippine and other national in the markets.On the contrary, we Granule product when being applied to rice field, eliminated drift, and " albefaction " is reduced to and is not present or can be received Degree.Pass through , clomazones (FMC of the present invention3ME labels), it is this prevailing to tropical rice field and temperate zone rice field Many main weeds (such as barnyard grass, bald barnyard (Echinochloa colonum), wide leaf Brachiaria Griseb (Brachiaria Platyphylla), knotgrass (Digitaria spp.), Panicum (Panicum spp.), Sprangletop (Leptochloa Spp.)) there is the active ingredient of very high intrinsic activity, and be reintroduced into an entirely different security concept.Jiang Yi Evil Another benefit that humulone is reintroduced back to is that it can partly control Oryza punctata (Oryza punctata), and spot is wild Raw rice is a kind of weeds maximum to rice yield limitation, also lacks one kind so far to its selective herbicide.
Clomazone (in the present invention) does not also contact directly without drift , clomazones with any of rice leaf. Therefore, with other products containing clomazone (such as3ME) apply and compare, its poisoning to rice it is very light or Without poisoning.It need not worry clomazone and be applied to the neighbouring region for having sensitive crop.
On the other hand, the invention provides a kind of rice herbicide composition, it contains at least one and is selected from the first kind Herbicide active ingredient and at least one herbicide active ingredient for being selected from the second class.In a preferred embodiment In, rice herbicide composition contains at least three kinds herbicide active ingredients selected from the first kind and the second class.It is for example, a kind of Preferable rice herbicide composition can contain sulfentrazone, penoxsuam He clomazone.
It is observed that sulfentrazone, the combination of penoxsuam He clomazone may have synergistic effect to moleplant seed. For example, we show in Filipine field test, with three kinds of different test samples (SPC1, SPC4 and SPC5), with every kind of Dosage for 320g ai/ha (gram active ingredient/hectare) (wherein only containing 183g ai/ha clomazones) is handled, Just show within only after administration the 8th day to preventive effect (table 29) of the moleplant seed up to 86%, 88% and 88%, the subsequent time after It is continuous to improve, reach 90%, 88% and 90% in 43DAA.Moleplant seed was in for 3 leaf phases (table 24) during dispenser.
Possible synergistic effect originates from the fact that：183g ai/ha clomazone is anti-except moleplant seed, and this is only According to the 1/5-1/3 (2014 of FMC Product labellings recommended dose (552-893g ai/ha clomazones) for moleplant seed Issue in 14 days 2 months3ME, page seven).
It should also be noted that moleplant seed has been artificially introduced in our experiment, therefore the density that moleplant seed occurs can Can be more much higher than what is (do not reported under FMC experimental conditions and be artificially introduced moleplant seed).
In the experiment specially designed from one, we further demonstrate that this synergistic effect.First, experiment, which have collected, comes From the moleplant seed of two different places of Philippine, with eliminate from a specific local moleplant seed might have (although not It is too possible) " birth defect ".Second, moleplant seed has only been introduced in experimental plot to avoid coming from other main weeds and moleplant seed Competition.3rd, one in two spraying times is postponed till into 15DAS (in 10-15DAS time window) so that a thousand pieces of gold Son grows bigger.All these adjustment are provided to make moleplant seed than being more difficult to kill in formerly experiment.(two are come to moleplant seed Individual area) test result show, in 10DAS with 320g ai/ha dispensers, reached 91% in 7DAA, reached in 21DAA 97% identical preventive effect；In 15DAS with 320g ai/ha dispensers, 96% (area 1) and 95% (area 2) are reached in 7DAA Preventive effect, and reached the preventive effect (table 39-40) of identical 98% in 21DAA.Under conditions of relatively harsh, only use different The 1/5-1/3 of Evil humulone recommended doses just can quickly kill moleplant seed, and always with the recommended dose in past 30 years, seemingly Best explanation is exactly synergistic effect.
According to definition, synergistic effect is effect caused by a kind of entirety, and it is more than the simple addition of various pieces.In this feelings Under condition, either single sulfentrazone or penoxsuam are not all almost lived to the moleplant seed in the 2.5-4.5 leaf phases Property.In addition, controlled-release technology merely control sulfentrazone at any given time in burst size, as it was previously stated, sulfentrazone It is inactive to the moleplant seed in the 2.5-4.5 leaf phases.It is considered that this significant synergistic effect is (in the 2.5-4.5 leaf phases / to three/5ths of , clomazones dosage very little, simply recommended dose for moleplant seed) come from clomazone, The combination of " sulfentrazone invalid to moleplant seed " and " penoxsuam invalid to moleplant seed ".
In a preferred embodiment, sulfentrazone:Penoxsuam:The proportion of clomazone is (1-5): (1-4):(2-12) and its any displacement.It is highly preferred that sulfentrazone:Penoxsuam:The proportion of clomazone is (1- 2):(1-3):(2-8)。
South Korea is temperate zone rice belt, wherein nutgrass flatsedge and broad leaved weed, it is anti-that especially sulfonylurea herbicide has been produced Property nutgrass flatsedge and broad leaved weed be significant challenge, our experiment displays in this, i.e., using the only granule containing sulfentrazone, Also having good preventive effect to all weeds, (in 30DAA, 120g ai/ha and 180g ai/ha sulfentrazone are respectively 87% and 91%) (table 51).It is reported that in all weeds of experimental test, rice barnyard grass (Echinochloa oryzicola), Monochoria vaginalis (Monochoria vaginalis) and firefly Lin (Scirpus Juncoides) are all it is reported that being sulfonylurea herbicide Agent resistant weed, but sulfentrazone is still effective (table 46) to Monochoria vaginalis (table 45) and firefly Lin.
Due to the control release of accurate timing, farthest utilize the active ingredient and relatively low on the whole of load Dosage, the residual activity pole of second stubble crop (including lower stubble sensitive crop) may be influenceed after crop harvesting, in soil It is few.Without waiting for the phase between planting after harvesting and again, such as by the way that soybean, mung bean, corn, onion and tomato are planted immediately Previous rice season is implanted in save in the same rice terrace that our product treatment is crossed to prove.Any poisoning is not observed.
In addition, this product effect performance in being widely applied it is consistent-from japonica rice to long-grained nonglutinous rice, from transplanting rice, (machinery moves Plant/manually transplanting) Direct-seeding Rice is arrived, and from the rice seedling of 10 ages in days to 30 ages in days and the rice seedling of the above.
Control weeds method
Applied the invention further relates to a kind of method that weeds are controlled in rice field, including by foregoing disposable herbicide composition For in rice field.
Using when, herbicide active ingredient gross weight is 5-1280g ai/ha.The dosage of final preparation composition is preferably 1-75kg/ha, such as 10kg/ha, or 20kg/ha.
In a preferred embodiment, composition is applied to long-grained nonglutinous rice or japonica rice Tanaka.
The opportunity of applying of Direct-seeding Rice and transplanting rice is that 7-15DAS (after planting number of days) and 5-15DAT (transplant the day after tomorrow respectively Number), this is overlapping using opportunity for the first time with nearly all herbicide.
Compared with prevailing spray solution form, our product is lighter, safer, more effective using getting up, Also it is more convenient.Track and apply in order to facilitate operator, composition of the invention can leave traceable mark in rice field.
Active ingredient release profiles
We have selected the combination of this active ingredient as above and afterwards described, be to have benefited from dual work to be formed The product of synergistic effect (see below) is shown with mechanism and to moleplant seed.This product kills the possibility of these weeds more It is high.The mechanism of our controlled-release technologies is exactly in these active ingredients that the release of specific opportunity is appropriate within the period of about 40 days. So, the technology ensure that there are enough herbicide concentrations to target but are still safe to crop, to realize described in us " first controlling the weeds sprouted, then prevent new weed germination in a continuous manner ", here it is it is of the invention with it is any existing There is the difference of technology.
Due to the timely release of active ingredient, it is ensured that the availability of fresh active ingredient, result in more effective and longer Long residual activity.The technology contributes to our excellent properties of product generally.
There is document report to describe slow release tech.It should remind, slow release method is different and is limited to it The relevant environment of value can be provided.E.g., including but it is not limited to, active ingredient release is relatively slow but still within a few houres or one day Situation about all discharging.Such slow release method will not have than the similar techniques of no sustained release in rice weed control aspect appoints What extra value.
In a word, if controlled-release technology is to add extra value in the formula of no this technology to carry out control targe, this Kind controlled-release technology just has to show the ability of release active ingredient at least 30 day time.
It is noted that many slow release methods are that its release is measured under conditions of vibration, this is used to say that not to applying Reality, because release is occurred under the conditions of glitch-free in actual rice field.
The production of the herbicidal composition of the present invention can be completed by the following method, for example, being with or without solvent In the case of, first at least one foregoing herbicide active ingredient is evenly dispersed in polymer to form release components, so The component is ground afterwards, fiber extrusion or misting cooling (or other proper methods) turn into predetermined particle diameter particle, then, will obtain The particle obtained and other herbicide active ingredients (if any), and necessary auxiliary agent such as dispersant, adhesive, wetting Agent, carrier, surfactant, filler etc. mix, then by mixture pelleting and drying, obtain the herbicidal composition.

The field test is only the assessment to poisoning, does not assess the preventive effect to weeds.Rice drug misadventuring rank is 0- 100%, 0% represents no poisoning, and 100% represents that all rice are dead.
Poisoning investigation stops in 7DAA, because：(1)Caused with 77% rate of release unacceptable initial Poisoning (table 22) and (2) are not if initial 7 days after dispenser symptom of chemical damage occur, then 57% and 33% rate of release is not yet The poisoning (table 22 and Fig. 2) of rice can be further resulted in.It should be noted that 24 hours rates of release of sulfentrazone are rice One predictive factors of poisoning, but be not unique.
The sulfentrazone controlled release granule of table 22. andIn influence of the different assessment opportunitys to rice seedling
Embodiment 14:In direct seading rice field, three kinds of granule samples (contain 1.4%, 2.1%, 2.8% has respectively Imitate composition) performance comparision between two kinds of standard items
Active ingredient in this experiment in three kinds of granule samples is respectively sulfentrazone, penoxsuam He Yi Evil are careless Ketone.The active ingredient total content of every kind of sample is respectively 1.4%, 2.1% and 2.8%.Their formula is listed in F1, F2 of table 4 And F3.
This experiment is carried out by SynTech in the experiment station in Jia Wannaduan cities of Philippine.Crop is live long-grained nonglutinous rice, dispenser opportunity It is 10DAS.
In order to ensure all Tropical Rice fields main weeds exist with significant density of growing thickly, except their nature In the presence of outside, field duckbilled grass seed is also introduced to field with 6kg/ha, remaining weed seed (barnyard grass, moleplant seed, field duck Mouth grass, Monochoria vaginalis, cusp flower, Ludwigia octovalvis (Jacq.) Raven, difformed galingale herb, miliary fimbristylis herb and cyperus iria) it is to be introduced with 2kg/ha.Drawing Before kind weed seed, all weed seeds all only soak 24 hours in advance.Then by the weed seed introduced a fine variety and thin dry ground Mixing, in order to sow by hand.The thickness of sowing of long-grained nonglutinous rice (NSIC Rc216) is 40kg/ha.Presprouting rice paddy seed and weeds Seed is sowed in experimental plot by hand together.Experimental plot ground moistening during sowing, but without ponding.
In addition to Monochoria vaginalis does not sprout, the sproutings of remaining rice and weeds and growth are normal, during to dispenser day (10DAS), overall weeds are very luxuriant.Detailed rice and weed data is listed in table 24.Measured in 9DAS rather than 10DAS Rice and the leaf phase of weeds and height, it is because it is infeasible to be applied with herbicide treatment while carry out such measurement.
This experiment follows randomized complete block design (RCBD).Each district's groups have 22 cells, wherein processing is randomly assigned, Separated between district's groups with 1 meter wide of irrigation canals and ditches of irrigation and draining.Each cell size is 20m2(4.0m x 5.0m), cell it Between ridging separate.Each 4 repetitions of processing.
The granule of test broadcasts sowing in the cell by hand in 10DAS.According to its label, sprayed in 15DAS by applying cauline leaf Spill two commercialization standard items100SC ' (bispyribac-sodium) and10%EC ' (metamifops), Then applied respectively in 28DAS100EC ' (cyhalofop-butyl), and 39DAS apply ' 2,4-D '.With equipped with hollow The knapsack sprayer of conical nozzle applies herbicide standard items.Spray value is 200L/ha.Using spraying backplate to keep away during spray Neighbor cell may be floated to by exempting from sprinkling.
When applying three kinds of granules, the cell depth of water about 0.5cm, and maintain 3 days after administration.Then in 4-10DAA water Increase to 1-3cm deeply, and maintain 3-5cm after this.
Spray the cell of standard herbicide, in sprinkling without ponding, introduce within the 3DAA days the deep water of 3cm, and in 11DAA and 3-5cm is maintained after it.
We have taken some precautions to reduce possible error, including flying bird drives device.In 4,10,15 and 17DAS takes four Niclosamide 70WP (molluscacide) of sprinkling to prevent and treat Pomacea canaliculata (Pomacea canaliculata). On following opportunity following insecticide and bactericide are applied with its label recommendations：' Furadan the 3G ' (carbofurans in 10DAS carbofuran)；' Actara 25WG ' (Diacloden thiamethoxam) during 14DAS；' Bigboss ' (efficient chlorine during 20DAS Flucythrinate lambda-cyhalothrin)；' Applaud 10WP+Philtap 50SP ' (Buprofezins+kill during 25 and 32DAS Snout moth's larva pellet hydrochloride buprofezin+Cartap hydrochloride)；' Chix 2.5EC+Applaud 10WP ' during 42DAS (effective cypermethrin+Buprofezin beta-cypermethrin+buprofezin)；' Benophyl 50WP ' (benzene bacterium during 43DAS Clever benomyl)；' Score 250EC ' (Difenoconazole difenoconazole) during 50 and 57DAS.In addition, the fertilizer recommended Management is performed as follows：120-40-40kg/ha NPK, respectively 14DAS40kg/ha NPK are applied in three times, then in 28 Hes 54DAS applies 40kg/ha N respectively.(continue to test, its purpose is to measure rice yield, and by same New sensitive crop is planted and observed in experimental plot to measure the residual activity after rice harves in soil.)
It has collected following data：It is upright and in appearance compared with untreated rice seedling based on rice seedling, in 3,8 and 15DAA observation rice seedlings poisoning (because the latter falls into weekend, being investigated in 8 and 15DAA rather than 7 and 14DAA)；Based on each 10 sample points of cell, in 36DAA (46DAS) and 43DAA (53DAS) measurement plant heights and count tiller number；8,15, 22nd, 29 and 43DAA assesses the preventive effect of each various weeds of cell；In 43DAA, at 4 angular distance ridge 50cm of each cell Respectively take 4 0.25m2Sample prescription, the quantity of various weeds in count quadrat；With ARM system analyze data；Climatic data come from away from Philippine's air geophysics in Jia Wannaduan cities of about 3.2 kilometers from SynTech experiment stations and astronomical management board (PAGASA).
Use two groups of commercialization rice herbicide products100SC+10EC and 10EC+2,4-D IBE are compared with three kinds of granule samples.This is two groups of rice herbicides of SynTech recommendations because of it Be local preferred.Dosage, order of administration and the time of application of two set products all follow strictly their label.
Each test granule sample sets six amounts of application, from 190g ai/ha to 760g ai/ha.Also set two in addition Individual control-mono- is not weeding, and another is manual uprooting weed.Relevant test sample, standard items, control, dosage, cell The details of area and time of application are summarized in table 23.

In 3,8 and 15DAA periodic investigation, SynTech reports that any one of three kinds of granule samples all do not have Poisoning is produced to rice seedling, even highest dosage 760g ai/ha.Due to there is no poisoning in initial two weeks rice, therefore in 22 Hes 29DAA investigation is omitted.Rice plant height and tiller number in the cell treated with particulate samples is all with craft Rice plant in the cell of uprooting weed is highly and within the normal range (NR) of tiller number.From two kinds of commercialization standard items (in use) Also any poisoning is not observed.
Table 27-36 is separately contained in 8,15,22,29 and 43DAA to all Weeds distributions and to main weeds species control The preventive effect information of system (7,14,21,28 and 42DAA are at a time when weekend).
For all weeds, with being only 83% and 65% respectivelyWithCompare, three kinds of tests Each in granule sample (SPC 1, SPC 4 and SPC 5) is even under 260g ai/ha low dosage, in 15DAA The preventive effect of identical 95% is all reached.With only needing dispenser once to prevent and kill off the test of grass family, broad-leaved and cyperus weeds Granula is different, and enough intrinsic activities are lacked for some main weeds standard items,WithIt is required for Again these main weeds are prevented and kill off using other different herbicides.That is,Also need to a kind of difference Anti- gramineous herbicide, be in this caseTo prevent and kill off the main grassy weed a thousand pieces of gold for influenceing the underproduction Son.A kind of other anti-broad-leaveds and the herbicide of nutgrass flatsedge are also needed to, is 2,4-D in this case, to prevent and kill off these Weeds.
For one group of three kinds of major target grassy weed (barnyard grass, moleplant seed and field duckbilled grass), with 77% in 15DAA and95% compared in 15DAA, three kinds of tests that each plant demand is 260g ai/ha Granule provides the average preventive effect of respectively 89%, 92% and 93% in 15DAA.It is a kind of grassy weed Herbicide, these three grass can be prevented and kill off.AndMoleplant seed can not be prevented and kill off, (the table as shown in its 77% harmonic(-)mean value 28-30)。
For one group of two kinds of major target broad leaved weed (cusp flower and Ludwigia octovalvis (Jacq.) Raven), with97% During 15DAA and51% compared in 15DAA, three kinds of test granules that each plant demand is 260g ai/ha exist Provided during 15DAA be 98% average preventive effect (table 31-32).As gramineous herbicideThis can not be prevented and kill off Two kinds of broad leaved weeds.
For one group of three kinds of major target nutgrass flatsedge (difformed galingale herb, miliary fimbristylis herb and cyperus iria), with 95% in 15DAA and20% compared in 15DAA, three kinds of tests that each plant demand is 260g ai/ha Granule provided in 15DAA be 98% average preventive effect (table 33-35).Except broad leaved weed can not be prevented and kill off,These three nutgrass flatsedges can not be prevented and kill off.
Apply in the banThen another herbicide is applied againWhen, overall Weed-control effect and three The average preventive effect of class weeds and each suitable (93-100%) in three kinds of test granules.And even inAfterwards Using 2,4-D, overall Weed-control effect and the preventive effect to broad-leaved and nutgrass flatsedge still be below three kinds of test granules and+Combination.
Above-mentioned experiment is not only not to carry out in laboratory in field, and be artificially introduced 8 kinds it is foregoing main The density of weeds and be uniformly distributed also all considerably beyond it is any in reality may occur seriousness.In the extreme case The unique security performance claimed to product of the present invention of test result let us and to the fast of the main weeds of three types Speed effect and sustainable prevent and kill off are filled with unbounded confidence.

The purpose of this experiment is to compare our test granule and the most popular rice herbicide product benzyl in locality is phonetic Sulphur is grand.The active ingredient for testing granule is sulfentrazone, penoxsuam He clomazone.Active ingredient total content in particle It is 1.4%.Formula is listed in the F1 of table 4.
This field test is by SSPC and SAAS patronage, is carried out in China Hainan province Lingao County Bo Lian towns Lu Lai villages.Make Thing is the artificial transplanting long-grained nonglutinous rice at the length of time rice seedlings grow on the 30th.
Experimental plot is prepared according to the practice of local farmers.First introduce water into field 3 days, then carry out plough over the ground and turn over simultaneously Carry out smooth, water level rises and is maintained at 3-5cm.
This experiment follows randomized complete block design (RCBD).Each district's groups are made up of 4 cells, with the row of irrigation between district's groups The small irrigation canals and ditches of water separate, wherein processing is randomly assigned.Each cell 54m2(3m x 18m), it is parallel between cell to be distributed and build Ridge separates.Each processing is repeated 3 times, and due to limited area, blank control is only repeated twice.
Weeds Lock-in and luxuriant.The main weeds in field are before the experiment and during experiment：Barnyard grass, lady's-grass (Digitaria setigera), dayflower (Commelina communis), Bermuda grass (Bermudagrass), special-shaped Sha Grass, cyperus iria, peppermint (Mentha haplocalyx Briq.) and Procumbent Falsepimpernel (Lindernia procumbens).
In 8DAT, put into practice according to locality, respectively will test particle and commercialization standard items (bensulfuron-methyl) independently with soil Mixing, then sow by hand in corresponding cell.
After dispenser, water level is increased to 10cm and keeps about week age.After one week, the intermittent phase of last for days be present, Cell is not aqueous during this period, because (1) local custom shows that this makes the deeper of rice root length；(2) water level in irrigation system Deficiency.In addition to during this, water has been always maintained at.
Fertilizer, insecticide and bactericide are taken the circumstances into consideration to apply by local farmers.
Only have two dosages for granule sample：315g ai/ha and 730g ai/ha.Relatively low-dose is used for Performance comparision is carried out with bensulfuron-methyl, and 730g ai/ha are used for assessing security of the granule to rice.Relevant test sample, Reference standard, control, dosage, plot area and dispenser opportunity etc. are shown in Table 41.
To test in the cell that granule treatment is crossed, weeds start to show poisoning symptom in 3DAA, while with light Micro- fragmentary rice drug misadventuring (<0.1%).Only have two plants of rice seedlings to show " albefaction " mark in the cell that all granule treatments are crossed As.
It is obvious to 20 DAA, contrast effect.Barnyard grass check plot and with bensulfuron-methyl treat cell in grow with Rice is equally high, and to test the no discovery barnyard grass of cell that granule treatment is crossed.
To 43 DAA, (amount to 108m in two check plots2) altogether find 40 plants of barnyard grasses, three with bensulfuron-methyl at (amount to 162m in the cell managed2) find there are 39 plants of barnyard grasses altogether, and at all 6 to test in the cell that granule treatment is crossed (common 324m2) only find 4 plants of barnyard grasses.In addition, to test in 6 cells that granule treatment is crossed, it is almost other miscellaneous without finding Grass, and control and the weeds with many of the treated cell of bensulfuron-methyl other species.
The weeds fresh weight of table 42.
SPC 1：The clomazone of+0.4% penoxsuam of 0.2% sulfentrazone+0.8% (F1 of table 4)；
Weeds：Barnyard grass, lady's-grass, dayflower, Bermuda grass, difformed galingale herb, cyperus iria, peppermint and Procumbent Falsepimpernel.
