Abstract
An assistant for herbicide to improve effect and decrease the consumption of herbicide is proportionally prepared from vegetative oil, surfactant and inorganic salt compound. Its application is also disclosed.
Description
Technical field
The invention belongs to the pesticide herbicide field, particularly, relate to a kind of auxiliary agent of weedicide.
Background technology
Along with the continuous development of agricultural production, agricultural chemicals plays an important role in the crop high yield.But, improve drug effect if in the weed killer herbicide use, rely on increase weed killer herbicide formulation rate, its result will not only cause agricultural cost to improve, and inevitably cause to the pollution of environment with to the injury of stubble susceptibility crop afterwards, influence agroecological environment and people's life and health.How to reduce unit are weed killer herbicide using dosage, improve herbicidal effect, reduce drug cost, increase weed killer herbicide will become modern agricultural chemicals application study to the correlation technique of the mankind, food, environment and other non-target biological safeties a focus.Simultaneously, how overcoming the influence of poor environment factors such as high temperature, arid to effect of herbicides, obtain stablizing effect, also is one of problem of paying close attention to of people.
Known some oils of people can promote the flushing liquor droplet to absorb and conduction at adhesion and spread, dissolving leaf epidermis wax, the promotion weed killer herbicide of leaf surface.Bibliographical information, sunflower methyl esters oil promotes diclofop-methyl, the absorption of fluazifop and sethoxydim and conduction (Nandula V.K.et al..Effectiveness of Adjuvants with Nicosulfuron andPrimisulfuron for Wirestem Muhly control in no-till Corn, Weed Tech., 1995,9:525-530), the seed oil that methylates can make clethodim control barnyard grass grass, the activity of wide leaf arm shape grass and false Chinese sorghum (the Jordan D.L.et al..Influence of Adjuvants on Efficacy of Clethodim that is enhanced about more than once, WeedTech., 1996,10:738-743), olein in the Canola oil and methyl oleate promote the absorption of gramineous plants to diclofop-methyl, and soybean oil improves dichloro quinolinic acid control green green bristlegrass preventive effect.U.S. Pat 6,642,178 have narrated oil-type adjuvant can improve weed killer herbicide to the preventive effects of weeds and provide one comprise multi-component auxiliary formula.
Summary of the invention
The object of the present invention is to provide the simple auxiliary agent of weedicide of a kind of prescription, this auxiliary agent not only can improve weed killer herbicide to the preventive effect of weeds, the dosage of reduction weed killer herbicide, and, add auxiliary agent of the present invention and can obviously improve weed killer herbicide preventing and kill off the anti-weeds of difficulty for the difficult anti-weeds of certain weed killer herbicide.Simultaneously, auxiliary agent of the present invention can guarantee that weed killer herbicide is to the preventive effect of weeds under the drought condition.
Technical scheme of the present invention is as follows:
Auxiliary agent of the present invention comprises the several components of natural source vegetable oil, mineral salt and surfactant.Hundred parts of content of its weight are as follows:
Natural source vegetable oil 50-80%
Surfactant 10-40%
Inorganic salt compound 10-15%.
Above each component directly is mixed, can obtains transparent, stable solution.
Above-mentioned natural source vegetable oil can derive from each plant species, can extract from fruit and the seed of plant, for example soybean oil, cottonseed oil, sunflower oil, rapeseed oil, cocoa butter, cupu oil or corn wet goods; And the carboxylate of above-mentioned natural source vegetable oil, for example can be through methylating of modifying, ethylization, butylation and other alkylating above each vegetable oil.Described each vegetable oil can be refined oil or slightly carry oil.
Surfactant is the important composition composition in most of herbicide formulations, has dispersion, adhesion, froth breaking, hydrotropy and activation, it is added on can promotes adhesion, moistening, diffusion and blade to absorb in the flushing liquor.Described surfactant is selected from one or more nonionics, cation or zwitterionic surfactant comprise the alkylphenol polyoxyethylene class, alkylphenol-polyethenoxy polyoxypropylene ethers, the benzylphenol APEO, fatty alcohol polyethenoxy ether class, the castor oil polyoxyethylene ether class, ethers nonionic emulsifiers such as ethylene glycol polyethenoxy ether class, the fatty acid ethylene oxide adduct, castor oil ethylene oxide adduct and derivative thereof, polyol fatty acid ester and ethylene oxide adduct etc. thereof, the phenol derivatives ethoxylate, the first nonyl phenol ethoxylate that contracts, phenol derivatives ethyoxyl propoxylate or polyethylene glycol laurate class etc.
Above-mentioned inorganic salt compound can be selected from ammonium sulfate, ammonium nitrate, triethanolamine, diammonium hydrogen phosphate, ammonium dihydrogen phosphate (ADP), potassium nitrate or ammonium molybdate, also can be selected from the mixture of above-mentioned mineral salt.
The present invention also comprises the using method of auxiliary agent of weedicide, comprises auxiliary agent is added in the herbicide spray liquid, perhaps mixes with the former medicine of weed killer herbicide earlier, and the weed killer herbicide formulation is made in reprocessing.For example, in actual use, the 0.25-1% of auxiliary agent of weedicide of the present invention with 1.5-3L/ha dosage or weed killer herbicide spouting liquid can be joined in the spray liquid of weed killer herbicide.
Auxiliary agent of weedicide of the present invention adds in the flushing liquor of seedling post processing weed killer herbicide, can obviously improve the drug effect of weed killer herbicide, reduce the consumption of weed killer herbicide, be applicable to the mixture of multiple weed killer herbicide and weed killer herbicide and weed killer herbicide and the mixture of weed killer herbicide and other agricultural chemicals, comprise acifluorfen, atrazine, bensulfuron-methyl, bentazone, chlorimuronethyl, clethodim, alkynes oxalic acid, clomazone, cyanazine, AC322140, cyhalofop-butyl, ethoxysulfuron, fenoxaprop-P, diclofop-methyl thiazole, efficient fluazifop, Flumiclorac pentyl, flumioxazin, fluoroglycofen-ethyl, fomesafen, grass ammonium phosphine, glyphosate, halosulfuronmethyl, fluazifop-butyl, miaow oxalic acid, methoxy miaow oxalic acid, imazethapyr, mesotrione, the piperazine humulone, nicosulfuron, oxasulfuron, paraquat, Stam F-34, pyrazosulfuron, two phonetic pair of phenylates, dichloro quinolinic acid, Quizalotop-ethyl, quinoline standing grain sugar ester, rimsulfuron, sethoxydim, the sulphur humulone, thifensulfuronmethyl, triasulfuron, tribenuron-methyl, weed killer herbicides such as triflusulfuronmethyl.
Use auxiliary agent of weedicide of the present invention and can reduce unit are weed killer herbicide using dosage, improve herbicidal effect, reduce drug cost, increase weed killer herbicide the mankind, food, environment and other non-target biological safeties; Can overcome poor environment factor affecting such as high temperature, arid, obtain stable drug effect.

Indoor and field trial shows that all auxiliary agent can both obviously improve the preventive effect of weed killer herbicide to weeds, can reduce weed killer herbicide consumption 1/3-1/2, greatly reduces peasant's drug cost simultaneously.
For the difficult anti-weeds of certain weed killer herbicide, the adding of auxiliary agent of the present invention can make drug effect improve obviously.With the nicosulfuron is example (example 3), and this weed killer herbicide can not well be prevented and kill off the piemarker in the corn field to the anti-heterodyne of piemarker under the recommended dose of field, can obviously improve the preventive effect of nicosulfuron to piemarker behind the adding auxiliary agent.
In addition, the significant advantage of another of auxiliary agent of the present invention is to guarantee that weed killer herbicide is to the preventive effect (table 4) of weeds under the drought condition.Gongzhuling, Jilin in June, 2004 weather arid has had a strong impact on the preventive effect of weed killer herbicide clethodim to weeds; Guaranteed the preventive effect of clethodim after adding auxiliary agent of the present invention to weeds.
