Abstract
The invention discloses a kind of Herbicidal composition for paddy fields expanding weeding scope, said composition is made up of active component fenoxaprop, pyrazosulfuron and dichloro quinolinic acid, and the mass ratio between three is 10: 0.1 ~ 10: 1 ~ 50.The present invention can be used for that paddy field is disposable prevents and kill off grassy weed, sedge weed and broad leaved weed, has both expanded herbicide spectrum, has turn improved the safety of weed killer herbicide to paddy rice.
Description
Technical field
The present invention relates to a kind of composition for paddy field weeding, be mainly used in disposablely preventing and kill off rice field grassy weed, sedge weed and broad leaved weed, both expanded herbicide spectrum, solved again the drug injury problem that fenoxaprop is applied to paddy field.The invention belongs to weed killer herbicide and manufacture field.
Background technology
Fenoxaprop is optical activity highy potent herbicide, has special efficacy to grassy weed, has now been successfully applied to the crops such as wheat, soybean, beet, flax, peanut, rape, potato and vegetables.Pyrazosulfuron is super-high-efficient sulfonylurea herbicide, has been widely used in rice field and has prevented and kill off sedge weed and broad leaved weed, had certain inhibitory action to barnyard grass.Dichloro quinolinic acid is heterocycle herbicide, is that the rice field of hormone-type is special except barnyard grass agent, to above the average age for marriage barnyard grass Be very effective, has become the herbicides special that barnyard grass is prevented and kill off in China rice field at present.The function of above three kinds of weed killer herbicides and feature are for everybody knows altogether.The herbicidal spectrum of these three kinds of weed killer herbicides respectively has feature, but is used alone and all can not reaches the effect that all weeds are prevented and kill off in a dispenser.And fenoxaprop China is mainly used in wheat paddock or barley field, the successful examples being used for weeding at paddy field is few, and main cause Shi fenoxaprop easily produces poisoning to paddy rice, can suppress paddy growth, make rice dwarf, even large area withered.
Summary of the invention
The object of the invention is, in order to overcome above defect, to provide the Herbicidal composition for paddy fields that a kind of safety is good, a dispenser can save season weeding from damage.We are found by research, with in the application in agricultural production three kinds of herbicides of extensive use compose different weed killer herbicide mixtures, and add herbicide-safener and improve safety to crop, new Herbicidal composition for paddy fields can be obtained.
Object of the present invention can be reached by following measures:
Expand a Herbicidal composition for paddy fields for weeding scope, said composition is made up of active component fenoxaprop, pyrazosulfuron and dichloro quinolinic acid, and the mass ratio between three is 10: 0.1 ~ 10: 1 ~ 50.
In a kind of preferred version, the active component fenoxaprop of said composition, the mass ratio between pyrazosulfuron and dichloro quinolinic acid are 10: 0.1 ~ 5: 10 ~ 50.
In a kind of preferred version, the active component fenoxaprop of said composition, the mass ratio between pyrazosulfuron and dichloro quinolinic acid are 10: 1 ~ 5: 15 ~ 40.
Composition of the present invention also comprises herbicide-safener mefenpyrdiethyl and/or fenchlorazole; Wherein the mass ratio of fenoxaprop and herbicide-safener is 1: 0.1 ~ 10, is preferably 1: 0.1 ~ 5.
Fenoxaprop is optical activity highy potent herbicide, and English common name: Fenoxaprop-p, has special efficacy to grassy weed.
Pyrazosulfuron is super-high-efficient sulfonylurea herbicide, English common name: Pyrazosulfuron-ethyl, has been widely used in rice field and has prevented and kill off sedge weed and broad leaved weed, had certain inhibitory action to barnyard grass.
Dichloro quinolinic acid is heterocycle herbicide, English common name: Quinclorac, is that the rice field of hormone-type is special except barnyard grass agent, to above the average age for marriage barnyard grass Be very effective, has become the herbicides special that barnyard grass is prevented and kill off in China rice field at present.
Herbicide-safener mefenpyrdiethyl, is the special safener of weed killer herbicide, effectively can alleviates the injury of weed killer herbicide to crops.English common name: Mefenpyr-diethyl.
Herbicide-safener fenchlorazole, is the special safener of weed killer herbicide, effectively can alleviates the injury of weed killer herbicide to crops.English common name: Fenchlorazole.
By above method by three kinds of weed killer herbicide mixtures, and add herbicide-safener, so both can expand herbicide spectrum, reach a dispenser, hold concurrently except the object of various weeds, peasant can be facilitated again to use, reduce spraying times, alleviate peasant's labour intensity.And owing to adding herbicide-safener, improve the safety of weed killer herbicide, protect crops, guarantee the good harvest of agricultural high yield.
Composition of the present invention can be processed into the various formulations of pesticide by active component and insecticides adjuvant (comprising herbicide-safener).The weight percentage of this formulation Pesticides auxiliary agent (comprising herbicide-safener) is 99%-1%.
Insecticides adjuvant of the present invention is including but not limited to one or more of dispersant, stabilizing agent, disintegrant, wetting agent, safener, binding agent, antifreeze, emulsifier, defoamer, thickener or filler etc.
Filler of the present invention is including but not limited to white carbon, kaolin, diatomite, bentonite, precipitated calcium carbonate, gypsum, attapulgite, soluble starch, organic solvent, cosolvent, vegetable oil, mineral oil, water, nitrogen fertilizer, one or more of glucose, Anhydrous potassium carbonate, natrium carbonicum calcinatum, Carbon Dioxide hydrogen potassium, anhydrous sodium sulfate etc.
The formulation that the present composition can be prepared includes but not limited to wetting powder, water dispersible granules, aqueous emulsion or suspending agent etc.
By carrying out mixture to the active component in foregoing invention by different formulations and attached with safener mefenpyrdiethyl and/or fenchlorazole, various formulation is prepared into through formulations of pesticide Conventional processing methods, through cold, heat stabilization test and storage at normal temperature stability test, filter out the formula that physicochemical property is stable, through biological activity determination, obtain preventive effect high, toxicity is low, the Herbicidal combinations that environmental influence is little, result of the test shows, three kinds of herbicide active active ingredients are mixed under proper proportion, herbicide spectrum can be expanded, contrast the effect also with synergy with each single dose result of use simultaneously, reach the object that a dispenser prevents and treats full field weed.After particularly having selected herbicide-safener mefenpyrdiethyl and/or fenchlorazole, observe drug effect and poisoning situation through biological test, result shows that the safety of this Herbicidal combinations improves greatly than contrast, produces a desired effect.
The present invention is compared with background technology, and Herbicidal combinations not only containing composite reactive composition, and is added with herbicide-safener in composition, both disposablely can prevent and kill off paddy field weed, cost is low, environmental protection, again to crop safety, without poisoning.
