Abstract
The invention discloses a kind of weed killer herbicide with broad spectrum weeding function, active ingredient is made up of benzene thiazole humulone and dichloro quinolinic acid, with suspending agent or wetting powder for product forms.Composition weed killer herbicide raw material weight per distribution ratio is benzene thiazole humulone 1 ~ 15%, dichloro quinolinic acid 1 ~ 50%, and auxiliary agent content is 2 ~ 25%, and filer content is 10 ~ 96%.The present invention has efficiently, the herbicidal performance of wide spectrum, mainly applies in corn field annual weed is prevented and kill off, has no adverse effects to crop.
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.
Dichloro quinolinic acid is a kind of special efficacy selective herbicide being mainly used in preventing and treating barnyard grass in paddy field at present, remarkably productive to 4-7 leaf phase barnyard grass.Selectivity is strong, and the amplitude broad in dispenser period, a dispenser can control the barnyard grass of whole growth period duration of rice.Effectively can also prevent and kill off Monochoria vaginalis, Chinese celery etc.Poor to the control efficiency of sedge weed.This compound can be absorbed by seed, root and the leaf portion of sprouting, and has the feature of hormone herbicide, similar to the effect symptom of auxin substance.The detailed mode of action in plant corpus is still among research.There is slight chlorosis phenomenon in barnyard grass of being injured tender leaf, blade occurs longitudinal stripe and bends.After sandwich barnyard grass is injured, leaf chlorosis becomes puce to withered; Active ingredient can be decomposed, thus to rice safety by the root of paddy rice.This compound has larger mobility in soil, can be decomposed by edaphon.
Summary of the invention
The object of the invention is the multiple weak point existed for current wide spectrum, highy potent herbicide shortage and existing weed killer herbicide, provide a kind of and there is weed killer herbicide that is efficient, broad spectrum weeding function simultaneously.
The present invention is made up of active ingredient and auxiliary agent, filler, described active ingredient is made up of benzene thiazole humulone and dichloro quinolinic acid, benzene thiazole humulone accounts for 1 ~ 15% of weed killer herbicide gross mass, dichloro quinolinic acid accounts for 1 ~ 50% of weed killer herbicide gross mass, auxiliary agent accounts for 2 ~ 25% of weed killer herbicide gross mass, and filler accounts for 10 ~ 96% of weed killer herbicide gross mass.
The present invention adopt benzene thiazole humulone and dichloro quinolinic acid 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 dichloro quinolinic acid 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.
Advantage of the present invention: benzene thiazole humulone and these two kinds of combination of active principles of dichloro quinolinic acid 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 dichloro quinolinic acid is a kind of broad-spectrum herbicide, annual after corn field seedling and perennial grassy weed is prevented and kill off all there is good effect.Therefore benzene thiazole humulone and dichloroquinoline acid 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 dichloro quinolinic acid single dose use cost higher, it is not again fine that low dosage is used alone effect, and therefore benzene thiazole humulone and dichloro quinolinic acid combinationally use preventive effect and improve, again reduce agriculture this.
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.
