Description

A kind of Herbicidal combinations and uses thereof and using method
[technical field]
The present invention relates to a kind of Herbicidal combinations, specifically, relate to a kind of Herbicidal combinations that contains picloram derivative and fragrant phenoxy propionic acid ester as active component.
[background technology]
Crops all need to use a large amount of weed killer herbicides for this reason and carry out weed control to retrieve crop yield loss because weeds harm causes crop yield to reduce every year.In recent years, the harm of weeds on diversified economy crops such as soybean is more and more serious, and because the weed killer herbicide abuse makes weeds produce increasing resistance to agricultural chemicals, causes weed control efficacy to reduce year by year.The weed killer herbicide kind that therefore, need have better preventive effect.
Picloram is a kind of systemic herbicide, can be rapidly by leaf and root absorption, and in plant corpus, conduct.It acts on metabolism of nucleic acid, makes plant produce excess nucleic acid, makes some structural transformations become meristematic tissue, causes blade, stem and root growth deformity, and reserve substance exhausts, and vascular bundle tissue is by embolism or break, and plant is death gradually.
Virtue phenoxy propionic acid class weed killer herbicide is at first developed by Hoechst AG, and the report diclofop-methyl had activity of weeding in 1975, and Dow Chemical had found pyrrole fluorine Chlorophenocarb in 1976, developed a plurality of kinds thereafter.This type of weed killer herbicide is widely used in broad leaf crop in China, and to prevent and kill off grassy weed ， fenoxaprop be that wheatland is prevented and kill off one of main weed killer herbicide kind of amur foxtail, wild oat.
Most of fragrant phenoxy propionic acid class weed killer herbicides can be absorbed rapidly by plant leaf blade, are transmitted to the meristematic tissue of radical bud in symplast.Individual other kind such as diclofop-methyl also by root absorption, can only carry out limited conduction in plant corpus except being absorbed by blade.This class herbicide action is in acetyl-CoA carboxylase, thereby inhibition fatty acid is synthetic.Their selectivity is mainly caused by katabolism difference, can promptly be degraded to the material of non-activity in chemical sproof plant corpus.
In order to increase the absorption of plant to fragrant phenoxy propionic acid class weed killer herbicide, the commodity preparation of this class weed killer herbicide is an ester, rather than acid, preparation as quizalofop-ethyl is 10% ethyl ester (quizalofop-ethyl), the preparation of pyrrole fluorine Chlorophenocarb is methyl esters (haloxyfop-methyl), resolves into activated acid after the plant absorbing rapidly.
Virtue phenoxy propionic acid class weed killer herbicide is used in the broad leaf crop field and prevents and kill off annual and perennial grassy weed mainly as the cauline leaf inorganic agent.Some kind also can be used on the cereal crop, is used in wheat paddock as diclofop-methyl, galloping horse, and the prestige despot is used in paddy field.
The gentle soil moisture content influence of being bullied of the drug effect of virtue phenoxy propionic acid class weed killer herbicide is bigger.Dispenser during, soil moisture content difference low at temperature, herbicidal effect is bad; In temperature height, good, dispenser when weed growth is vigorous of soil moisture content, herbicidal effect is good.(as 2,4-D) antagonism is arranged, promptly they use with the weed killer herbicide of this class weed killer herbicide and interference hormonal balance, and herbicidal effect can descend.
