Abstract
The invention relates to a herbicide containing topramezone and atrazine. The herbicide is a two-member herbicide composition with topramezone and atrazine as effective components, wherein the weight ratio of the effective component topramezone to the effective component atrazine is 1:15; the herbicide can be prepared into any allowed dosage forms in agriculture. The herbicide is used for preventing and removing weeds in corn fields, has significant synergic effect compared with alone application of the components, can broaden weed killing spectrum, reduces preventing and removing cost, retards generation of weed resistance, and has good safety to crops.
Description
Technical field
The present invention relates to a kind of herbicidal composition for Control Weeds in Maize Field, be specifically related to a kind of for preventing and kill off the weed killer herbicide that contains benzene azoles humulone and atrazine of corn field grassy weed, broad leaved weed.
Background technology
Corn is important cereal crops, is also important forage crop.In recent years, along with the development of the industries such as livestock breeding, food processing, wine-making industry and biodiesel, the market demand of corn constantly increases.China is the country that has throughout the year corn growth, North gets ，Nan Dao Hainan Province, Heilongjiang Province, has corn planting, and 2010 Annual planting areas reach 3,000 ten thousand hectares, is only second to paddy rice, wheat planting area.Continuous expansion along with maize sown area, nonirrigated farmland crop smothering also day by day expands, and in recent years, Chemical Weeding in Maize Field has become the important technical links of guaranteeing corn safety in production, but because drug of choice is improper or operation technique is not in place, control efficiency is undesirable or produce the phenomenons such as poisoning and occur repeatedly.Thereby medicinal herb grower just need to select a kind of high activity, herbicide wide ranges and the weed killer herbicide to plant height safety.
In use, atrazine dosage is large, and herbicide spectrum is wide not, poor to many grassy weed preventive effects, and its lasting period is longer, during large usage quantity, second stubble crop wheat and other broad leaf crops is had to certain influence.Benzene azoles humulone activity is high, and consumption is low, uses optimum period wide after seedling, uses flexibly, and broad weed-killing spectrum, can prevent and kill off annual gramineous weed and broad leaved weed, but cost is high while using separately, is unfavorable for spread.Therefore, benzene azoles humulone, atrazine are carried out to rational mixture, to reach the object of synergy, reduction consumption and cost, expansion herbicide spectrum.
Summary of the invention
The object of this invention is to provide a kind of weed killer herbicide that contains benzene azoles humulone and atrazine that is applicable to corn field, can prevent and kill off grassy weed and can prevent and kill off broad leaved weed again, and can reduce medicament usage amount and to corn safety.
The present invention is achieved by the following technical solutions: a kind of weed killer herbicide that contains benzene azoles humulone and atrazine, and its active ingredient is benzene azoles humulone and atrazine, the weight ratio of described benzene azoles humulone and atrazine is: 1:15; Weight percentage in herbicidal composition is 80%, and surplus is one or more in the upper acceptable insecticides adjuvant of the agriculturals such as carrier, solvent, emulsifier, wetting agent, dispersant, thickener, defoamer, antifreezing agent.
According to different uses, need or applying environment, herbicidal composition of the present invention can be prepared into any formulation allowing in multi-form agricultural by conventional at present pesticide producing mode, and herbicidal composition most preferred dosage form of the present invention is oil suspending agent.
Benzene azoles humulone is benzoylpyrazole herbicides, after seedling, cauline leaf is processed, by root, seedling and leaf, absorb, in plant Xiang Ding, to base, be transmitted to meristematic tissue, suppress p-hydroxyl oxygen phenylacetone acid esters dual oxide enzyme (4-HPPL), suppress plastoquinone and indirectly suppress the biosynthesis of carotenoid, make chloroplast synthesize suppressed and dysfunction.Chlorophyllous oxidative degradation causes the susceptible weeds albefaction of germinateing, and follows growth inhibition, and under photosynthesis, its symptom of being injured is like chlorotic necrosis, and bleaching symptom appears in responsive target weeds after processing in 2～5 days, and in 14 days, plant is dead.Its broad weed-killing spectrum, prevents and kill off corn field annual gramineous weed and broad leaved weed effective, and the lasting period is long, normally uses crop safety.
Atrazine is selectivity inner-adsorption conduction-type herbicide, by root system and cauline leaf, is absorbed, and conducts to rapidly plant meristematic tissue and leaf portion, suppresses weeds photosynthesis, makes grass cutting blade flavescence, hungry dead.In the resistance crop bodies such as corn, medicament can be resolved into innocuous substance by corn ketolase, so to crop safety.Atrazine is water-soluble larger, has larger mobility in soil, easily by rain, is arrived compared with deep layer, causes some deep-rootedness weeds is had to inhibitory action.
In described insecticides adjuvant, carrier can be one or more in white carbon, kaolin, diatomite, bentonite, precipitated calcium carbonate, gypsum, attapulgite, soluble starch, urea, amine fertilizer, glucose, maltose, sucrose, citric acid, natrium carbonicum calcinatum, Carbon Dioxide hydrogen potassium, anhydrous sodium sulfate, anhydrous sodium bicarbonate, Anhydrous potassium carbonate, or other this area common carrier.
In described insecticides adjuvant, solvent can be one or more in water, benzene,toluene,xylene, methyl alcohol, ethanol, isopropyl alcohol, butanols, cyclohexanone, cyclohexanol, oxolane, tetrahydrofurfuryl alcohol, carrene, chloroform, dimethyl formamide, dioxane, 1-METHYLPYRROLIDONE, ethyl acetate, acetone, butanone, ether, epoxidized soybean oil, plant soybean oil, liquid wax, lubricating oil.
In described insecticides adjuvant, emulsifier can be phenethyl phenol polyethenoxy polyethenoxy ether, styryl fluosite PULLRONIC F68 block type polyethers, aliphatic acid polyethenoxy ether, dibenzyl xenyl APEO, glyceryl monolaurate APEO, styrylphenol polyoxyethylene ether, ethoxy castor oil APEO, alkyl phenol polyoxyethylene polyoxypropylene ether, secondary octyl phenol polyethenoxy ether, polyoxyethylene nonylphenol ether, aliphatic alcohol polyoxyethylene sulfonate, polyoxyethylene alkylphenol formaldehyde condensation products, dodecyl sodium sulfonate calcium, decyl alcohol polyoxyethylene ether sulfosuccinic acid sodium, alkylphenol polyoxyethylene succinate monoester sulfonate, alkylphenol-polyethenoxy phosphate, alkylphenol polyoxyethylene sulfosuccinates, one or more in fatty acid polyethylene glycol ester.
In described insecticides adjuvant, dispersant can be one or more in alkylnaphthalene sulfonate, polycarboxylate, sodium lignin sulfonate, sodium metnylene bis-naphthalene sulfonate, calcium lignosulfonate, Sodium Polyacrylate, alkyl naphthalene sulfonic acid condensation polymer sodium salt, sodium methylene bis-naphthalene sulfonate formaldehyde condensation products.
