Description

A kind of Herbicidal composition for rice field

Technical field

The present invention relates to a kind of Herbicidal composition for rice field, by active constituent (R) -2- [4- (chloro- 1, the 3- benzoxazoles of 6- - 2- oxygroups) phenoxy group]-N, N- dicyanos methyl propanamide and KIH 6127 and auxiliary agent composition, belong to technical field of compounded pesticide.

Background technology

(R) -2- [4- (chloro- 1, the 3- benzoxazoles -2- oxygroups of 6-) phenoxy group]-N, N- dicyano methyl propanamides belong to benzene Bing oxazole -2- oxygroup phenoxy group propionyl imine compounds, can inhibit the acetyl-CoA carboxylase (ACCase) of grassy weed Activity, for preventing and kill off the weeds on crops, the particularly grassy weeds such as rice terrace barnyard grass, moleplant seed, lady's-grass, eleusine indica, It is good to Security of rice.

KIH 6127, English name pyriminobac-methyl, chemical name are：2- [(4,6- dimethoxypyridin -2- bases) Oxygen] -6- [1- (N- methoxyiminos) ethyl] methyl benzoate, inner-adsorption conduction-type herbicide, for rice direct seeding field or shifting Field is planted, 3 leaf phase pervious barnyard grasses can be prevented and kill off, and effective to broad leaved weed and nutgrass flatsedge.Pesticide-clay mixture, cauline leaf spraying treatment can be used, to water Rice is extremely safe.

By literature search, at present it is not yet found that (R) -2- [4- (chloro- 1, the 3- benzoxazoles -2- oxygroups of 6-) phenoxy group] - The relevant report of N, N- dicyano methyl propanamide and KIH 6127 compounding.Inventor is screened by a large amount of formula indoor and field The test of pesticide effectiveness is found (R) -2- [4- (6- chloro- 1,3- benzoxazole -2- oxygroups) phenoxy group]-N, N- dicyano methyl propionyl After amine and KIH 6127 are compounded in a certain range, to rice terrace, annual and perennial grassy weed has apparent increase Effect acts on, and can expand control of weeds spectrum, reduce use cost, delaying drug resistance, to crop safety height.

Invention content

The purpose of the present invention is to provide a kind of component is reasonable, synergistic effect is notable, and herbicidal effect is good, and control of weeds spectrum expands Greatly, drug cost is low, energy delaying drug resistance, and to the Herbicidal combinations of rice safety.

Another object of the present invention is to provide a kind of Herbicidal combinations preparation formulation.

It is still another object of the present invention to provide above-mentioned compositions to prevent and kill off the annual and perennial grass family of rice terrace miscellaneous Application on grass.

Specific embodiment

Illustrate active constituent (A) below by Toxicity Determination：(R) -2- [4- (the chloro- 1,3- benzoxazoles -2- of 6- Oxygroup) phenoxy group]-N, N- dicyanos methyl propanamide and KIH 6127 are compounded to paddy field weed whether having a synergistic effect.

In order to prevent and kill off paddy field weed, the synergy that we have carried out mutual compounding with active constituent (A) and KIH 6127 is studied, Test method refers to《The People's Republic of China's farm-chemical indoor determinations of agricultural industry criteria NY/T1155.3-2006 experiment Criterion herbicide third portion：Active determination test soil spray-on process》With《People's Republic of China (PRC) agricultural industry criteria NY/ The 7th part of the farm-chemical indoor determination test rules of T1155.7-2006 herbicide：The synergy of mixture measures》.

Subjects are the annual and perennial grassy weed of rice terrace：Barnyard grass（Echinochloa crusgalli）、 Moleplant seed（Leptochloa chinensis）, lady's-grass（Digitaria sanguinalis）, eleusine indica（Eleusine indica）, rice Leersia Sw（Leersi ahexandra）.

Experiment uses the content of organic matter to air-dry sandy loam for 2%, pH 6.8, the good sieving of permeability.Selection is easy to train Support, breeding time consistent barnyard grass, moleplant seed, lady's-grass, eleusine indica, rice Leersia Sw seed, germination percentage is more than 80%.It will experiment Soil is quantitatively filled at the 4/5 of basin alms bowl, using basin alms bowl bottom infiltrating irrigation mode, makes soil complete wetting.Weed seed is uniformly spread Soil surface, earthing 1.0cm are sowed at, sowing carries out soil spraying treatment afterwards for 24 hours.

Single dose and each Mixed Pharmacy set 5 various concentration gradients（On the basis of pilot study result, matched according to medicament Than difference, concentration gradient setting is also different, prevents and kill off rate and is set in the range of 5%~90% by geometric progression）.If clear water pair According to being repeated 4 times.Weeds are in germination period, carry out spraying treatment respectively from low dosage to high dose.Processing is placed in greenhouse and trains Support observation, the moisturizing in a manner of the bottom infiltrating irrigation of basin alms bowl.

21 days after the processing fresh weight preventive effects for calculating each chemicals treatment, pass through the probit value of preventive effect and the logarithm of series concentration Between linear regression analysis, the ED of each medicament is obtained₅₀ Value calculates the co-toxicity coefficient of mixture with the abundant methods of Sun Yun（CTC）, with this To evaluate activity of the reagent agent to weeds.

The co-toxicity coefficient of complex preparation（CTC）>=120 show as synergistic effect；CTC≤80 show as antagonism；80 ＜ CTC ＜ 120 show as summation action.

Biological Examples 1：Prevent paddy field weed field control effectiveness test.

Inventor has carried out example of formulations 1 in 2017 in Junichiro Koizumi village of xiangtan, hunan province county（30% (A) KIH 6127 breast Oil）, example of formulations 3（45% (A) KIH 6127 wettable powder）, example of formulations 5（35% (A) KIH 6127 water-dispersible grain Agent）, example of formulations 7（26% (A) KIH 6127 aqueous emulsion）, example of formulations 9（22% (A) KIH 6127 microemulsion）, preparation Embodiment 11（28% (A) KIH 6127 aqueous suspension agent）, example of formulations 13（The 26% dispersible oil-suspending agent of (A) KIH 6127）It is anti- It harnesses the river weeds in paddy field field control effectiveness test, demonstrates control effect of the medicament to paddy field weed and the safety to rice.

Trial crops are rice, and controlling object is the annual and perennial grassy weed of rice terrace：Barnyard grass （Echinochloa crusgalli）, moleplant seed（Leptochloa chinensis）, lady's-grass（Digitaria sanguinalis）, eleusine indica（Eleusine indica）, rice Leersia Sw（Leersi ahexandra）, rice is broadcast during dispenser 3 days afterwards, in 1 heart stage of 1 leaf, weeds were in germination period.Experimental plot topography is flat, and soil fertility is medium, pH value 7.1.Investigational agent Agent and dosage refer to table 6.Blank control separately is set, often processing is repeated 4 times, per 30 ㎡ of cell, the random district's groups arrangement of cell.Using normal Advise spray-on process, mu dispenser liquid 45kg.

Each processing weeds strain preventive effect of 30d investigation after medicine.Investigation method is to investigate per cell at 2 points, every 0.25m²（0.5m× 0.5m）.Drug effect computational methods are：

Wherein：CK is the careless number of blank district work（Or fresh weight）；PT is the careless number for the treatment of region remaining（Or fresh weight）.

Table 6 prevents paddy field weed field control effectiveness test strain preventive effect

Table of field test results are bright, and more than example of formulations dosage is 3 g a.i./mu, annual and perennial to rice terrace Grassy weed has a good control effect, after medicine the average preventive effect of 30 days be significantly better than that 20% (A) suspending agent, 10 g a.i./ The preventive effect of mu, the dispersible oil-suspending agent 3g a.i./mu of 20% KIH 6127.By to 30 days significance difference analysis after medicine, compounding Combination and other single doses processing preventive effect otherness are notable.

Security survey：Safety of each processing of 7d, 15d range estimation to rice seedlings after medicine.Observation result is, all to supply reagent The poisoning phenomenons such as paddy growth safety, no chlorisis, dwarfing occur for agent.

In conclusion the composition of the present invention is using two kinds of active components compound scheme, activity and herbicidal effect are not It is the simple superposition of each component activity, compared with existing single formulation, in addition to significant herbicidal effect, and has significantly Synergistic effect, preparation less residue is pollution-free to crop, and safety is good, meets the security requirement of pesticidal preparations.
