Abstract
The invention discloses a herbicide composition with broad-spectrum synergistic weeding effect. The active components of the herbicide composition are benzothiazole carfentrazone-ethyl and acetochlor, and a suspending agent or a wettable power serves as a product dosage form. The herbicide composition comprises, by weight, 1-25% of benzothiazole carfentrazone-ethyl, 1-35% of acetochlor, 2-25% of an auxiliary agent and 15-96% of a filling material. The herbicide composition is a herbicide pesticide composition, shows high-efficiency and broad-spectrum weeding performance, is mainly applied to annual weed control in corn fields and exerts no harmful effect on crops.
Description
Technical field
The present invention relates to the preparation method of herbicidal composition.
Background technology
Corn is the main food long-term cropping of China, and national corn seeding area is stabilized in about 4.5 hundred million mu always for many years.Corn planting distribution is wide, has spring corn and summer corn two kinds of planting patternss.Field weed community is different because of local natural conditions and farming feature, roughly can be divided into 6 crop smothering districts such as Spring Maize crop smothering district, northeast, Huang-Huai-Hai corn field of summer crop smothering district.Corn field weed occurs general, and main weeds has lady's-grass, barnyard grass, green foxtail, eleusine indica, Amaranthus retroflexus, kitchen garden, acalypha copperleaf, the rhizome of nutgrass flatsedge etc.Current chemical herbicide have steriland herbicide and selective herbicide point, selective herbicide have again processing soil treatment agent and cauline leaf inorganic agent not, and have contact-type and conduction type point.Different components, the weed killer herbicide of different cultivars, its herbicide spectrum, adaptability and the susceptibility to crop have difference, but corn field herbicide is multifarious on market, peasant does not often know how to select, and many peasant households falsely drop misuses weed killer herbicide, causes unnecessary harm to corn growth.So understand weed killer herbicide kind and proper use of be the key of corn control of weeds.
Super-high-efficient, low toxicity, the low-residue green weed killer herbicide of benzene thiazole humulone to be a kind of with PPO be action target, can be used for corn field and prevent and kill off multiple broad leaved weed.
Acetochlor is selectivity bud pre-treatment weed killer herbicide, hypocotyl mainly through monocotyledonous coleoptile or dicotyledon absorbs, and absorbs backward upper conduction, synthesizes and Cell growth inhibition mainly through hindering protein, weeds young shoot, young root are grown stop, so dead.The energy force rate broad leaved weed that grassy weed absorbs Acetochlor is strong, so the effect of preventing and kill off grassy weed is better than broad leaved weed.About the 45 days lasting period in soil of Acetochlor, mainly through microbial degradation, the mobility in soil is little, mainly remains in 0-3 cm layer of soil.
Summary of the invention
The object of the invention is for current wide spectrum, highy potent herbicide lacks and existing weed killer herbicide exists multiple weak point, provide a kind of with suspending agent or wetting powder for formulation, there is herbicidal composition that is efficient, broad spectrum weeding function simultaneously.
The present invention is made up of active ingredient and auxiliary agent, filler, it is characterized in that described active ingredient is made up of benzene thiazole humulone and Acetochlor, benzene thiazole humulone accounts for 1 ~ 25% of herbicidal composition gross mass, Acetochlor accounts for 1 ~ 35% of herbicidal composition gross mass, auxiliary agent accounts for 2 ~ 25% of herbicidal composition gross mass, and filler accounts for 15 ~ 96% of herbicidal composition gross mass.
The present invention adopt benzene thiazole humulone and Acetochlor composite, there is efficient, broad spectrum weeding function, expand weeding scope simultaneously, excellent preventive effect is shown to weeds such as corn field lady's-grass, moleplant seed, polygonum flaccidum, cyperus iria, Amaranthus retroflexus, exceedes the use of benzene thiazole humulone and Acetochlor two single dose kinds.To crop safety, cost is low, preventive effect good.Proving after tested, herbicidal composition stable chemical nature of the present invention, high-efficiency broad spectrum, revealing obvious broad-spectrum weed-killing and complementation to preventing and kill off Object table.
The formulation of product of the present invention is wetting powder, also can be suspending agent.
When formulation is wetting powder, described auxiliary agent auxiliary agent is by dispersant 1 ~ 20%, and wetting agent 1 ~ 5% forms, and dispersant adopts lignosulfonates, NNO, the one pulling open powder or any two or three mixture.Wherein, lignosulfonates select calcium lignosulfonate or sodium lignin sulfonate; Wetting agent adopts sodium alkyl benzene sulfonate or alkyl benzene calcium sulfonate.Filler adopts a kind of in silica-based, precipitated calcium carbonate, white carbon or mixture, silica-based employing potter's clay, kaolin and diatomite etc.
When formulation is suspending agent, described auxiliary agent is by dispersion moisture agent 1 ~ 15%, antifreeze 0.3 ~ 3%, thickener 0.4 ~ 5%, defoamer 0.3 ~ 2% forms, dispersion moisture agent adopts polyoxyethylene tri-styryl phosphenylic acid salt, or alkylnaphthalene sulfonate, or one in alkylphenol polyoxyethylene or mixture; Antifreeze adopts antifreeze to adopt alcohols, selects propane diols or glycerine or ethylene glycol; Thickener adopts xanthans or aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent.Filler adopts water.
Advantage of the present invention: benzene thiazole humulone and these two kinds of combination of active principles of Acetochlor use, and expand weeding scope and herbicidal effect.Through test determination: benzene thiazole humulone is used for preventing and kill off multiple broad-leaved resistant weed, but poor to the preventive effect of grassy weed.And although Acetochlor is a kind of broad-spectrum herbicide, has annual after corn field seedling and perennial grassy weed and there is good effect, poor to multiple broad leaved weed preventive effect.Therefore benzene thiazole humulone and acetochlor composition wide spectrum that corn field is reached for key resistance Weed infestation and synergistic effect the most remarkable.Secondly use cost reduces, current benzene thiazole humulone and Acetochlor single dose use cost higher, it is not again fine that low dosage is used alone effect, and therefore benzene thiazole humulone and Acetochlor combinationally use preventive effect and improve, again reduce agriculture this.
