Abstract
The present invention provides a herbicidal composition comprising as active ingredients a compound (A) represented by the formula (I) (I) and a compound (B) represented by the formula (II)
Description
The application is a divisional application with application number 201510563280.1, application date 2015, 9 and 7, and title "a herbicidal composition".
Technical Field
The invention relates to a weeding composition. The invention also relates to a method for controlling undesired vegetation.
Background
the weeds in the rice fields are various, and the weeding in the rice fields is a great problem in production. Chemical weeding is the main means of controlling weeds. In recent years, however, many weeds have become resistant to chemicals due to the wide area of individual use of some herbicide species. Meanwhile, the weed phase is complex when the weeds occur, various weeds such as gramineous weeds, broad-leaved weeds and nutgrass flatsedge are mixed, and the weeds in the farmland can not be solved by using a single variety of herbicide, so that the defects and the limitation of a certain aspect can be shown.
On the other hand, herbicides used for field crops of rice, particularly paddy fields, are required to have a high selectivity. Although herbicides generally do not cause phytotoxicity to crops and can control weeds, they may cause phytotoxicity to crops due to various causes such as gas phase, environment, misuse, and the like. In particular, in the case of a growth-inhibiting herbicide, phytotoxicity is liable to occur under excessive moisture conditions. Therefore, it is required to develop a herbicide which does not cause phytotoxicity to crops even under the above-mentioned severe conditions, can control weeds, and has high selectivity between crops and weeds.
Propyrisulfuron (Propyrisulfuron) is a pyrimidinylsulfonylurea herbicide developed by the chemistry of Sumitomo, and is mainly used for preventing and killing gramineae and broadleaf weeds such as barnyard grass in paddy fields. The product has low dosage and good control effect on weeds with resistance to certain known sulfonylurea herbicides. Propyrisulfuron has good control effect on annual and perennial paddy field weeds such as barnyard grass and difficult-to-deal water chestnuts, arrowheads and the like. Although propyrisulfuron belongs to sulfonylurea herbicides, propyrisulfuron still has good activity on weeds with resistance to certain known sulfonylurea herbicides. The propyrisulfuron is mainly a herbicide for killing in one step in the early and middle period, can be prepared into pesticide preparation products such as suspension concentrate or large tablets and the like, and is directly thrown into the field.
Propyrisulfuron, molecular formula C16H18O5N7SCl, the molecular structure of which is shown below:
（I）
Triazine flumioxazin (Triaziflam) with molecular formula C17H24FN5O, the molecular structural formula of which is shown as follows:
Triazinyl flumioxazin is a novel s-triazine herbicide developed by Idemitsu Kosan in japan in the late 90 s of the 20 th century. This compound is disclosed in US 5290754. The triaziflam is mainly used for preventing and killing gramineous weeds and broadleaf weeds in rice fields before and after seedling emergence. The triaziflam can act on a plurality of sites (inhibiting photosynthesis, microtubule formation and cellulose formation), has a brand new weeding mechanism, and is favorable for delaying the formation of weed resistance.
the sulfonylurea herbicide is a selective systemic conduction type herbicide, can be absorbed by weed roots and leaves, is quickly conducted in plant bodies to inhibit cell division and growth, and after sensitive weeds absorb the herbicide, sprouts and roots quickly stop growing, tender tissues are yellowed and then die. However, the sulfonylurea herbicides still have some problems in application, most notably residual phytotoxicity and resistance of weeds to the sulfonylurea herbicides.

although the compounds (a) and (B) already exhibit good or even sufficient selectivity in a large number of crops, in principle phytotoxicity to the crop plants may occur in some crops, in particular also in combination with other less selective herbicides. Compositions comprising the herbicidal compositions according to the present invention together with one or more safeners are particularly advantageous. The safeners are used in antidotally effective amounts, for example to reduce the phytotoxic side effects of the herbicides used in economically important crops or in fruit plantations (plantation crops). Such as cereals (wheat, barley, rye, oats, maize, rice and millet), sugar beet, sugar cane, oilseed rape, cotton and soybeans, preferably cereals, in particular rice.
The following are, for example, compounds suitable as safeners (including possible stereoisomers and agriculturally commonly used esters or salts): benoxacor (benoxacor), cloquintocet (-mexyl)), oxabetrinil (cyclotrinil), cyprosulfamide (cyprosulfenamide), dichlormid (dichlormid), dicyclonon, o-phenyl thiophosphoric acid o, o-diethyl ester (dietholate), fenchlorazole (-ethyl)), fenclorim (fenclorim), sulfentrazone (flurazole), fluxofenamide (fluxofenam), furazolazole (furilazole), isoxadifen (-ethyl)), mefenapyr (mefenpyr (-diethyl)), 4-chlorophenyl methylcarbamate (mephenate), naphthalic anhydride (oxabetrinil).
some safeners are known to act as herbicides and, accordingly, to act to protect crop plants in addition to having a herbicidal effect on harmful plants.
the weight ratio of herbicidal composition to safener depends in general on the application rate of the herbicide and on the effect of the safener and can vary within wide limits, for example within the range from 90000: 1 to 1: 5000, preferably within the range from 7000: 1 to 1: 1600, in particular within the range from 3000: 1 to 1: 500, in particular within the range from 1:100 to 20: 1. Safeners can be formulated with compounds (a) and (B) as finished formulations or supplied and used in tank-mix with the herbicidal composition.
The invention provides the use of a herbicidal composition for controlling undesired vegetation.
The invention provides an application of a weeding composition in preventing and killing undesirable vegetation of broadleaf weeds, cyperaceae weeds and gramineous weeds.

Rice (Oryza) such as rice (Oryza sativa) and african rice (Oryzaglaberrima);
Sugar cane;
Legumes (Fabaceae)), including, for example, soybeans (Glycine max.), peanuts (Arachis hypogaea) and legume crops such as peas (including peas (Pisum sativum), pigeon peas and cowpeas), beans (including broad beans (Vicia faba), Vigna nigra (Vigna nigra) and Vigna nigra (Phaseolus)), and lentils (lentils var);
cruciferae families, including, for example, canola (Brassica napus), rape (Brassica napus), cabbage (b.oleracea var.), mustard such as mustard (b.juncea), chinese cabbage (b.campestros), chinese tarda (b.narinosa), black mustard (b.nigra), and mediterranean turnip (b.tournefortii); and turnip (Brassicapa var.);
Other broad leaf crops, including, for example, sunflower, cotton, flax, linseed, sugar beet, potato, and tomato;
TNV crops (TNV: trees, nuts and vines), including, for example, grapes, citrus, pome fruits, such as apples and pears, coffee, pistachios and oil palms, stone fruits, such as peaches, almonds, walnuts, olives, cherries, plums and apricots;
turf, pasture and pasture;
Onion and garlic;

The herbicidal compositions of the present invention are very useful. The herbicidal composition of the present invention exerts a remarkable synergistic effect, i.e., exerts good herbicidal activity even when the amount of each of the compound (a) and the compound (B) applied is small, and therefore, the influence on the surrounding environment is reduced. Furthermore, the herbicidal composition of the present invention reduces the hazard of useful crops as compared with the case where each agent is applied alone. On the other hand, the herbicidal composition of the present invention also provides a herbicidal composition which is longer in persistence, i.e., remains residual efficacy, than the case where the compound (a) and the compound (B) are applied separately.
The herbicidal compositions of the present invention also provide excellent control of the growth of undesirable vegetation in non-crop areas. Non-crop areas such as roads, railways, lawns, utility lines, and particularly in areas where trees are present, undesirable vegetation.
The herbicidal compositions of the present invention may also be used for crop plants that are resistant to one or more herbicides due to genetic engineering or breeding, resistant to one or more pathogens, such as phytopathogenic fungi, due to genetic engineering or breeding or resistant to insect infestation due to genetic engineering or breeding. Suitable are, for example, crops which are resistant to synthetic auxins, preferably maize, wheat, sunflower, rice, canola, oilseed rape, soybean, cotton and sugar cane, or crops which are resistant to attack by certain insects as a result of introduction of genes for Bt toxins by genetic modification.
Use of a herbicidal composition for controlling undesired vegetation in crops of useful plants, which is safe for said useful plants.
If the active ingredient is not well tolerated by certain crops, the herbicidal compositions can be directed to spray with the aid of a spray device so that they contact the sensitive crop as little as possible when they reach the foliage or bare soil of the undesirable plants growing below.
The present invention also provides a method for reducing or preventing damage caused by compound (a) to the plants of the crops of useful plants, to the seeds of the crops of useful plants or to other reproductive parts of the crops of useful plants treated therewith, which comprises treating the plants of the crops of useful plants, the seeds of the crops of useful plants or other reproductive parts of the crops of useful plants with a herbicidal composition as described herein.
The application rate of the herbicide can vary widely, the optimum amount depending on the herbicide, the spectrum of the harmful plants and the spectrum of the crop in question. The desired level of herbicide will depend on the particular weed infestation, the spectrum of weeds to be controlled, the adjuvant, etc. It is most preferred to use relatively low amounts of herbicide. The activity of the herbicidal composition of the present invention is higher than the expected sum of the activities of the respective herbicides applied, and the compound (a) and the compound (B) exhibit a synergistic effect.
The synergistic effect results in a reduction in the application rate of the individual herbicides and a higher efficacy at the same application rate. In the herbicidal compositions of the present invention, the application rate of the individual compounds is reduced while the herbicidal composition simultaneously maintains a good level of action; secondly, the compositions achieve a high level of weed control when the individual substances in the low application rate range have become useless from an agronomic point of view.
Thus, application of the herbicidal compositions of the present invention can significantly reduce the application rates of the individual components of the compositions, thereby reducing phytotoxicity to crops.
The present invention provides a method for controlling undesired vegetation by applying the compound (a) and the compound (B) of the herbicidal composition of the present invention to undesired plants or their growing sites, together or separately.
A method for controlling undesired vegetation, comprising: (i) applying a herbicidally effective amount of the herbicidal composition of the present invention to the undesired plants or to the locus thereof before germination (pre-emergence), (ii) after germination (post-emergence), or (iii) at both (i) and (ii). Preferably, the application of the germinated undesired vegetation (e.g. broadleaf weeds, grasses, cyperaceae or undesired crop plants) is also carried out before the undesired vegetation germinates, irrespective of the growth period of the sown/planted crop.
the herbicidal composition of the present invention comprises an effective amount of the compound (a) and the compound (B) having a synergistic effect. A synergistic effect is observed when compound (a) and compound (B) are administered together or nearly simultaneously; a synergistic effect may also be observed when compound (a) and compound (B) are administered separately at different times; it is also possible to apply (A) and (B) sequentially, for example pre-emergence and then post-emergence, or early post-emergence and then mid-or late post-emergence. It is preferred here to administer compound (a) and compound (B) jointly or virtually simultaneously, and particular preference is given to coadministration.
if the herbicidal composition of the present invention is applied to the soil surface before germination, the weed seedlings are completely prevented from germinating, or the weeds grow to the cotyledon stage, but then they stop growing, and finally die completely after two to four weeks.
If the active compound is applied to the green parts of the plants after germination, the growth likewise stops sharply within a relatively short time after the treatment, and the weed plants remain in the growth phase at the point in time of application, or they die completely after a certain time, in such a way that the competition caused by the weeds which are harmful to the crop plants is eliminated earlier and continuously. For rice, the herbicidal composition may also be applied in water, which is then absorbed through the soil, shoots and roots.
when compound (a) or compound (B) is co-administered, there is a synergistic enhancement. Here, the activity of the composition is higher than the expected sum of the activities of the individual herbicides applied. The synergistic effect allows a reduction in the application rates, a broader spectrum of broadleaf weeds, grasses and cyperaceae to be controlled, a faster onset of action of the herbicidal action, a longer duration, a better control of harmful plants by only one or a few applications and a widening of the application period. The dosage used in the herbicidal composition and the effective dosage of compounds (a) and (B) can be adjusted to lower levels to minimize the effect on the soil. This allows the herbicidal compositions of the present invention to be applied not only to sensitive crops but also almost avoid groundwater contamination. The herbicidal compositions of the present invention allow for a significant reduction in the required application rate of the active ingredient.
The above characteristics and advantages are necessary for weed control to keep agricultural/forestry/horticultural crops or greens/grasslands free from undesired competing plants, thereby ensuring and/or increasing the yield level of useful crops from the point of view of quality and quantity. Such herbicidal compositions significantly exceed the state of the art in terms of said properties.
The present invention also provides a method of controlling undesired vegetation which comprises applying the herbicidal compositions of the present invention in the presence of the plants of the useful crop, the seeds of the useful crop or other reproductive parts of the useful crop.
The present invention also provides a method for controlling undesired vegetation, preferably in crops of useful plants, in particular in crops of rice, which comprises applying the compounds (a) and (B) as herbicidal compositions according to the invention, for example jointly or separately, to plants (for example undesired plants, such as monocotyledonous or dicotyledonous broadleaf weeds, grasses, cyperaceae or undesired crop plants), seeds (for example caryopsis, seeds or vegetative organs, for example tubers and sprouted branches), or to areas where plants grow (for example areas of cultivation, which may also be covered with water). One herbicide may be applied to the plant, seed, or area where the plant is growing (e.g., the area of cultivation) before, after, or simultaneously with another herbicide.
The herbicidal compositions of the present invention may be applied in a conventional manner by using techniques well known to those skilled in the art. Suitable techniques include spraying, atomizing, dusting, broadcasting or pouring. The type of application depends in a well-known manner on the intended purpose; in any case, the technique should ensure the best possible distribution of the active ingredients according to the invention.
The invention is most preferably used for controlling weeds in the area where the crop is growing or will be used for growing the crop, by unwanted plants or their locus. When applied to a crop growing area, the application rate should be sufficient to control weed growth without causing serious permanent damage to the crop.
"undesirable plants" are understood to mean all plants which grow in places where their growth is not desired. These may be, for example, harmful plants (for example monocotyledonous or dicotyledonous weeds, grasses, cyperaceae or unwanted crop plants), including, for example, those which are resistant to certain herbicidally active compounds (for example triazinflufenacet, glyphosate, glufosinate, atrazine, imidazolinone herbicides and sulfonylureas).
The herbicidal composition of the present invention can be applied by various application methods commonly used for herbicides for rice. Particularly preferably, it is applied by spray application and/or by dip application. In the dip application, the water in the paddy field has covered the ground up to 3-20cm at the time of application. The herbicidal composition of the present invention is then placed directly in the water of the paddy field. Worldwide, spray application is mainly used for directly sown rice, while dip application is mainly used for transplanted rice.
the present invention also provides a method for controlling undesired vegetation by contacting the undesired plants or their growing locus with a herbicidally effective amount of the herbicidal composition of the present invention or applying a herbicidally effective amount of the herbicidal composition of the present invention to water.
the present invention also provides a herbicidal composition which exhibits high selectivity between crop plants and weeds even under severe conditions such as excessive water, which is liable to cause phytotoxicity, i.e., exhibits high safety to rice crops and high herbicidal activity against weeds difficult to control under conditions in which phytotoxicity is liable to occur.
The invention also provides a weeding composition, the active components of which consist of the compound (A) and the compound (B), a filling agent and/or a surfactant. In the herbicidal composition, the content of the compound (a) and the compound (B) is 1% to 90% of the herbicidal composition, and may be 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%. Preferably 1% to 80%, preferably 5% to 70%, more preferably 10% to 65%, more preferably 15% to 55%, still more preferably 20% to 50%
The herbicidal composition of the present invention can be converted into conventional formulations such as wettable powders, emulsifiable concentrates, suspensions, microcapsules, microemulsions, aqueous emulsions, suspoemulsions, water dispersible granules, aqueous emulsions, ultra-low volume liquids, tablets, low volume dispersible granules, pills, microcapsules.
According to the present invention, the term "bulking agent" refers to natural or synthetic organic or inorganic compounds that can be combined or associated with an active ingredient to make it easier to apply to a subject (e.g., a plant, crop or grass). Thus, the filler is preferably inert, at least should be agriculturally acceptable. The filler may be solid or liquid.
Suitable solid carriers are: for example, vegetable powders (for example, particles of soybean powder, starch, cereal powder, wood powder, bark powder, saw dust, walnut shell powder, bran, cellulose powder, coconut shell, corn cob and tobacco stalk, and residues after extraction of plant essence), clays (for example, kaolin, bentonite, acid china clay, etc.), and talc powders. Silica (for example, diatomaceous earth, silica sand, mica, hydrous silicic acid, calcium silicate), activated carbon, natural minerals (for example, pumice, attapulgite, zeolite, etc.), calcined diatomaceous earth, sand, plastic media (for example, polyethylene, polypropylene, polyvinylidene chloride, etc.), inorganic mineral powders such as potassium chloride, calcium carbonate, calcium phosphate, etc., chemical fertilizers such as ammonium sulfate, ammonium phosphate, urea, ammonium chloride, etc., and soil fertilizers, and these may be used alone or in combination of 2 or more.
Suitable liquid carriers may be selected from, for example, water, alcohols (e.g., methanol, ethanol, isopropanol, butanol, ethylene glycol, etc.), ketones (e.g., acetone, methyl ethyl ketone, diisobutyl ketone, cyclohexanone, etc.), ethers (e.g., diethyl ether, dioxane, methyl cellulose, tetrahydrofuran, etc.), aliphatic hydrocarbons (e.g., kerosene, mineral oil, etc.), aromatic hydrocarbons (e.g., benzene, toluene, xylene, mineral spirits, alkylnaphthalenes, chlorinated aromatic hydrocarbons, chlorinated aliphatic hydrocarbons, chlorobenzene, etc.), halogenated hydrocarbons, amides, sulfones, dimethyl sulfoxide, mineral and vegetable oils, animal oils, etc.
Suitable surfactants are emulsifiers, dispersants or wetting agents of an ionic or nonionic nature, or mixtures of these surfactants. Suitable examples of such surfactants include fatty alcohol-polyoxyethylene ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene higher fatty acid esters, phosphoric acid esters of polyoxyethylene alcohols or phenols, fatty acid esters of polyhydric alcohols, sodium alkylaryl sulfonates, naphthalenesulfonic acid polymers, lignosulfonates, high-molecular comb-shaped dendritic copolymers, butylnaphthalenesulfonates, alkylaryl sulfonates, sodium alkylsulfosuccinates, fats and oils, polyacrylic acid salts such as condensates of fatty alcohols with ethylene oxide and alkyltaurates, and protein hydrolysates. Suitable oligosaccharides or polymers are based, for example, on ethylene monomers, acrylic acid, polyoxyethylene or polyoxypropylene alone or in combination with, for example, (poly) alcohols or (poly) amines. When one of the active compounds and/or one of the inert carriers is insoluble in water and when applied in water, a surfactant must be present. The proportion of the surfactant is 5% -40% of the herbicidal composition of the present invention.
If appropriate, the herbicidal compositions according to the invention may also be provided with further additional components, for example protective colloids, adhesives, thickeners, thixotropic agents, penetrants, stabilizers, sequestering agents, complex-forming agents. In general, the active ingredient may be combined with any solid or liquid additive conventionally used for formulation purposes.
The herbicidal composition of the present invention can be prepared by mixing the active ingredient with at least one of the following substances in a known manner: liquid or solid carriers, emulsifiers, dispersants, wetting agents and/or protective colloids, binders, adhesives, thickeners, thixotropic agents, penetrating agents, stabilizers, sequestering agents, complex-forming agents, water and further processing aids.
In the herbicidal composition, the content of the compound (a) and the compound (B) is 1% to 90% of the herbicidal composition, and may be 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%. Preferably 1% to 80%, preferably 5% to 70%, more preferably 10% to 65%, more preferably 15% to 55%, still more preferably 20% to 50%
the herbicidal compositions according to the invention can be formulated by known methods, for example as mixed preparations of the individual components, if appropriate with further active compounds, additives and/or customary formulation auxiliaries, and the compositions are then diluted with water in a customary manner and applied; or can be formulated as a tank mix by diluting the separately formulated or partially separately formulated components together with water. It is also possible to apply the components separately or partly separately. The herbicide or herbicidal composition can also be used in multiple parts (sequential application), for example first as a seed dressing application or pre-sowing/pre-planting treatment or pre-emergence application followed by post-emergence application or early post-emergence application, followed by mid-or late-emergence application. Preference is given here to using the active compounds of the composition together or almost simultaneously, particular preference being given to co-administration.
The method of application may be selected according to the intended subject and prevailing circumstances, such as foliar, drench, spray, dusting, scattering, according to the nature of the formulation.
The compounds (a) and (B) may be administered as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They can be applied in a conventional manner, for example by pouring, spraying, atomizing or broadcasting.
The herbicidal compositions of the present invention have a more easily used form because the amounts of the components are already in optimal proportions. In addition, the auxiliaries in the formulations can be adjusted to one another for optimization.

Biological examples
Pre-emergence test:
The herbicide dosage is dependent on the optimum concentration determined in the field or under greenhouse conditions the test (100% effect = complete death of the plant; 0% effect = no phytotoxic effect) is evaluated after 2 ~ 4 weeks.
When the herbicidal composition of the present invention is applied before germination, emergence of weeds or growth of weeds to the cotyledon stage and then stop growing and death is complete after 3 ~ 4 weeks.
Post-emergence test
a potted plant stem and leaf treatment method (NY/T1155.4-2006) is adopted, quantitative soil is filled in a plastic pot with the height of 6cm and the diameter of 9cm, 15 ~ 20 seeds of monocotyledonous and dicotyledonous weeds are sown in the plastic pot, the plastic pot is covered with fine soil with the thickness of 0.5 ~ 1cm and then is placed in a greenhouse for culture, stem and leaf spraying treatment is carried out when the weeds grow to 2 ~ 4 leaves, 1mL of pesticide is sprayed in each pot, each treatment is repeated for 4 times, the treatment without the pesticide is set as a control, the treated weeds are placed in the greenhouse for culture, the growth condition of target weeds is regularly observed, the target damage symptoms and the growth inhibition condition are visually observed after 21d, the fresh weight of the overground part or the fresh weight of the weeds are weighed, and the toxicity effect of the pesticide on the target weeds is evaluated by the target.
Preparing three reagents according to a certain weight percentage: 1. propyrisulfuron; 2. triazine flumioxazin; 3. propyrisulfuron + triazinyl flumetsulam. Then, each of the reagents was diluted with water to obtain a diluted drug solution.
The investigation method comprises the following steps:
after the test treatment for 21d, the target damage symptoms and growth inhibition condition are visually observed, the fresh weight of the overground part is weighed, and the fresh weight inhibition rate (%) is calculated.
The evaluation of the synergistic effect shown in the mixed application of two or more herbicidal active ingredients was determined on the basis of the Colby's method described in "synergistic synergy and antibiotic Response of herbicidal Combinations" (Weeds 15/1(1967), s.r. Colby).
In the formula, X is the fresh weight inhibition rate of propyrisulfuron to target weeds when a certain dosage is used singly;
Y is the fresh weight inhibition rate of the triazineone flumioxazin to target weeds when a certain dosage is used singly;
E0The theoretical value of the inhibition rate of the propyrisulfuron and the triazinyl flumetsulam on the fresh weight of the target weeds when being mixed;
And E is a measured value of the inhibition rate of the promethasulfuron to the fresh weight of the target weeds when the promethasulfuron and the triaziflam are mixed.
If the actual weed control rate (E) observed in the bioassay exceeds the expected value calculated using the Colby's method (E)0) It means that the efficacy of the herbicidal composition is greater than the sum of the efficacies of the ingredients, which means that the composition has a synergistic effect.
The herbicidal compositions of the present invention were tested against the following broad spectrum of important harmful plants (grasses, broadleaves, cyperaceae): rice barnyard grass (Echinochloa oryzae) Stephania japonica, Euphorbia lathyris (Leptochloa achinensis), Digitaria sanguinea (Digitaria spp.), Stellaria media (Stellaria media), Amaranthus retroflexus (Amaranthus retroflexus), Polygonum Convolvulus (Fallopia (ex Polygonum) Convolvulus), Abutilon theophrasti (Abutilon), sulfonylurea-resistant edible wild herbs (Sagittaria trifoliata), Oriental Watertium Rhizome (Oriental Watertian Rhizome), sulfonylurea-resistant Ottelia communis (Herb of Pyrmy Arrowhead), Solomonia viridis (Monochoria korsporum), Clonospora strangulata (Linderniocus), Solanum nigrum L., Chenopodium album L., Iridium monnieri (Rough), Iridium officinale L., Avena (Avena sativa), Veronica (Avena L).
Activity on rice barnyard grass
Activity on Euphorbiae Lathyridis semen
Activity against large crabgrass
Activity against sulfonylurea-related cyperus
Activity against Veronica albo
The test results show that: the propyrisulfuron and the triazinyl flumetsulam show obvious synergistic action in the range of 1:100-100:1 for preventing and removing gramineous weeds, sulfonylurea-resistant broadleaf weeds and sulfonylurea-resistant cyperaceae weeds, effectively ensure the control of the weeds of partial prior sulfonylurea-resistant herbicides and improve the effect of controlling the resistant weeds
In conclusion, the control effect of the weeding composition is superior to the activity of each component when being applied independently, and the efficacy test proves that the weeding composition has a synergistic effect, the weed control spectrum is expanded, the gramineous weeds, the broadleaf weeds and the cyperaceae weeds in the crop fields are controlled and removed by one-time application, the application frequency is reduced, the control cost is reduced, the generation of weed resistance is slowed down, the safety to crops is good, and the safety requirement of pesticide preparations is met. Can be used for closed weeding before or after seedling in rice field, corn, soybean, grain, sunflower, potato, peanut and cotton field.
Safety action
Under greenhouse conditions, the test plant rice seeds were planted in plastic pots and grown to the 3-leaf stage in the plastic pots. The amount of water in the plastic tank is sufficient for the growth of the crop. At this stage, the individual compositions of propyrisulfuron, triazineamic, propyrisulfuron + triazineamic were applied to the test plants. The phytotoxicity of the herbicide to the crop was evaluated using a percentage measure 3 weeks after application. 100% means complete death of the test plants and 0% means no phytotoxic effect.
It can be seen that the combination of propyrisulfuron and triaziflam improves the compatibility of propyrisulfuron with crops, reduces or prevents the damage of propyrisulfuron to the plants of useful crops, the seeds of useful crops or other breeding parts of useful crops treated by the propyrisulfuron, and improves the safety of rice.
