Abstract
The invention relates to a weeding composition. The weeding composition is of a ternary complex weeding composition taking mesotrione, atrazine and acetochlor as active ingredients, and the raw materials are taken in percentage by weight: 1%-20% of the mesotrione, 1%-40% of the atrazine, 1%-40% of the acetochlo; and the weeding composition is of a suspension concentrate prepared by the active ingredients and auxiliary materials. The weeding composition disclosed by the invention is used for controlling annual gramineous weeds and broadleaf weeds in corn fields.
Description
Technical field the invention belongs to technical field of pesticide.The ternary weeding composition that specifically contains nitre sulphur humulone, atrazine and Acetochlor.
Background technology
Nitre sulphur humulone (mesotrione) is a kind of novel three ketones weed killer herbicide, both can seedling before native list processing, also can behind seedling, carry out the cauline leaf spraying, in instant effect, nitre sulphur humulone residual life in soil, is short, to succession crop safety.Simultaneously, its biologically active surpasses the sulphur humulone more than 10 times, has more potentiality to be exploited and competitiveness.Because it is environmentally friendly, calendar year 2001 sells in the EU countries and the U.S. in 2002 through the approval of Environmental Protection Agency USA.But its control efficiency for broad leaved weed common in the corn field such as Siberian cocklebur, japanese bearbind etc. is not very good.
Atrazine (atrazine) is before the interior suction selectivity seedling, herbicide after seedling.Root absorption is main, and cauline leaf absorbs seldom.The main plant root that passes through absorbs and upwards conducts, and suppresses photosynthesis of plants, makes it withered.Kill grass effect and the same Simanex of selectivity, easy by rainwater drip washing to soil than deep layer, also effective to some dark root grass.Lasting period is also longer.Its spectrum of grass extremely is wider, can prevent and kill off multiple annual gramineae and broad leaved weed., be applicable to dry crop weedings such as corn, Chinese sorghum, sugarcane, especially corn there is selectivity preferably.Be applicable to that corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land prevent and kill off lady's-grass, barnyard grass grass, green foxtail, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, some perennial weed is also had certain inhibitory action.
Acetochlor (acetochlor) is a kind of weed killer herbicide of extensive use.Being succeeded in developing in 1971 by U.S. Monsanto Company, is one of most important in the world weed killer herbicide kind at present, also is one of maximum weed killer herbicide of present China usage amount.It is a selectivity bud pre-treatment weed killer herbicide; Main hypocotyl through monocotyledonous coleoptile or dicotyledon absorbs, and the upwards conduction of absorption back is mainly synthesized and cell growth inhibiting through impede protein matter; Weeds young shoot, young root growth are stopped, so dead.The ability force rate broad leaved weed that grassy weed absorbs Acetochlor is strong, is superior to broad leaved weed so prevent and kill off the effect of grassy weed.Annual gramineous weeds such as lady's-grass, green foxtail, eleusine indica, barnyard grass grass, moleplant seed, amur foxtail, wild oat, annual bluegrass, hard grass, india lovegrass there is special efficacy, broad leaved weeds such as Chenopodiaceae, Amaranthaceae, polygonaceae, dayflower, ox chickweed 、 china dodder are also had certain preventive effect.
Some researchs show that using with between some weed killer herbicide can overcome or alleviate chemical injury of crops.Simultaneously, various weed killer herbicides are because of the difference of its chemical composition, physicochemical property, and it is also different to kill careless scope.It is narrower that some weed killer herbicide kills careless scope, but have one's own knack, and can eradicate the weeds that other weed killer herbicides are difficult to eliminate.Field trial shows, uses single weed killer herbicide not only to be easy to generate resistance and poisoning for a long time, also can cause bigger influence to soil environment.One of important measures that weed killer herbicide rationally uses are extensively thought in using with of weed killer herbicide; Therefore we are with nitre sulphur humulone, three kinds of different herbicide mixtures of herbicide effect mode of atrazine and Acetochlor; To reduce the generation of resistance; Enlarge and kill the grass spectrum, reduce influence, increase economic efficiency soil environment.
In present numerous formulations of pesticide, what comparatively generally use is liquid formulation, and wherein using maximum for a long time is missible oil; Yet in the missible oil in a large number with an organic solvent; Not only cause the waste of industrial chemicals, and environment and human health are brought very big murder by poisoning, simultaneously because the combustibility of solvent; Transportation, storage are brought great inconvenience, and therefore developing novel liquid formulation has become trend of the times to reduce or eliminate these virulent organic solvents.To the drawback of missible oil, more use suspending agent and aqueous emulsion as alternative formulation, yet to different types of former medicine, two kinds of formulations all have certain limitation at present.Suspension emulsion allows to be combined into single preparation to several kinds of inconsistent pesticide activity components most possibly; Exempt the trouble that bucket mixes before using, can reduce the quantity in stock of product, reduce spraying number of times crop; Save time and expense, ideal as alternative formulation.
Summary of the invention
