Abstract
The invention discloses a kind of Herbicidal combinations improving mesosulfuron safety, said composition is made up of active ingredient mesosulfuron and herbicide-safener, and wherein the part by weight of active ingredient azoles humulone and herbicide-safener is 10: 0.1 ~ 10.Present invention adds herbicide-safener; it improves than the mesosulfuron safety not adding herbicide-safener greatly to the safety of crops; decrease the generation of phytotoxicity accident, protect the interests of peasant, thus decrease the generation that social groups' property complains to the higher authorities about an injustice and request fair settlement event.
Description
Technical field
The present invention relates to the Herbicidal combinations that a kind of safety is good, the invention belongs to weed killer herbicide and manufacture field.
Background technology
Mesosulfuron belongs to sulfonylurea super-high-efficient weed killer herbicide, English general by name: Mesosulfuron-methyl.Mesosulfuron toxicity is extremely low, is all greater than 5000mg/kg to rat acute per os, percutaneous toxicity LD50.It absorbs mainly through the cauline leaf of plant, through phloem and xylem conduction, passes through soil absorption on a small quantity, suppress the activity of the acetolactate synthestase in sensitive plant body, cause the biosynthesis block of the numerous acid of side chain ammonia, thus T suppression cell division, cause sensitive plant dead.Generally, dispenser is after 2 ~ 4 hours, and the absorptive amount of susceptible weeds peaks, and stops growing after 2 days, and within 4 ~ 7 days, rear blade starts yellow, occurs withered spot subsequently, dead after 2 ~ 4 weeks.The safener contained in this product, can promote that it is doing to decompose rapidly in object, and does not affect its degraded in target weeds body, thus reaches the object of killing weeds, cover crop.Be applicable to use in soft and semi-rigid type winter wheat variety.Amur foxtail, wild oat, caput grass, annual bluegrass, hard grass, alkali thatch, Annual Ryegrass, lolium temulentum, bromegrass, candle grass, Triticum tauschii, Tong grass, wheatgrass, shepherd's purse, Descurainia sophia, ox chickweed, spontaneous rape etc. can be prevented and kill off.
Though mesosulfuron is super-active weed killer herbicide, have the weakness that fatal, it is poor to crop safety, easily produces poisoning to crop, causes the loss being difficult to retrieve to peasant, causes also to the reputation of manufacturer and has a strong impact on.
Summary of the invention
The object of the invention is to overcome above defect, providing a kind of and improving the good method of mesosulfuron safety.We are found by research, in mesosulfuron formulation, add herbicide-safener, can improve the safety of mesosulfuron to crops, thus constitute the good Herbicidal combinations of safety, decrease phytotoxicity accident and occur.
Object of the present invention can be reached by following measures:
Improve a Herbicidal combinations for mesosulfuron safety, said composition is made up of active ingredient mesosulfuron and herbicide-safener, and wherein the part by weight of active ingredient azoles humulone and herbicide-safener is 10: 0.1 ~ 10.
The herbicide-safener that the present invention selects is mefenpyrdiethyl or fenchlorazole, and they effectively can alleviate the injury of weed killer herbicide to crops.By adding herbicide-safener in mesosulfuron formulation, the safety of weed killer herbicide can be improved, protection crops, guaranteeing the good harvest of agricultural production high yield.
In a kind of preferred version, the part by weight of active ingredient mesosulfuron and herbicide-safener is 10: 1 ~ 10.
In a kind of preferred version, the part by weight of active ingredient mesosulfuron and herbicide-safener is 10: 5 ~ 10.
Composition of the present invention can by active ingredient mesosulfuron and herbicide-safener, and insecticides adjuvant, makes various formulation, includes but not limited to wetting powder, water dispersible granules, aqueous emulsion or suspending agent.
Insecticides adjuvant of the present invention weight percentage is in the formulation 99%-1%.Insecticides adjuvant is selected from one or more in dispersant, stabilizing agent, disintegrant, wetting agent, safener, binding agent, antifreeze, emulsifier, defoamer, thickener, filler.
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 Herbicidal combinations of raising safety of the present invention can be processed into the various formulations of pesticide for cornfield herbicidal, can prevent and kill off the multiple weeds in wheatland, effectively raises the safety of mesosulfuron weed killer herbicide to crops.
By adding herbicide-safener mefenpyrdiethyl or fenchlorazole in the active component mesosulfuron in foregoing invention, be prepared into the various formulations of pesticide through formulations of pesticide Conventional processing methods.Through hot and cold stability test and storage at normal temperature stability test, filter out the formula that physicochemical property is stable, through biological activity determination, obtain the Herbicidal combinations that preventive effect is high, toxicity is low, environmental influence is little, safety is good, result of the test shows, by mesosulfuron and herbicide-safener mefenpyrdiethyl or fenchlorazole mixture, in the biologically active of mesosulfuron, there will not be antagonism, observe poisoning situation through biological test, result shows that the safety of this Herbicidal combinations improves greatly than the mesosulfuron not adding herbicide-safener.
Present invention adds herbicide-safener; it improves than the mesosulfuron safety not adding herbicide-safener greatly to the safety of crops; decrease the generation of phytotoxicity accident, protect the interests of peasant, thus decrease the generation that social groups' property complains to the higher authorities about an injustice and request fair settlement event.
