Description
Technical field
The composition pesticide that the present invention relates to is to be active ingredient with efficient haloxyfop-methyl spirit with cloransulammethyl, is used for preventing and kill off farmland weed, is particularly useful for preventing and kill off soybean field annual weed.
Background technology
The efficient haloxyfop-methyl spirit, English common name
Haloxyfop-R-methyl, belong to phenoxy carboxylic acid herbicides, be selective herbicide behind the seedling, after handling, cauline leaf can be absorbed by the leaf of grass family class grass very soon, conduct to whole plant, suppress the plant meristematic tissue and kill dogstail.The medicament that sprinkling falls into soil is easily absorbed by root, also can play and kill grass effect, average 55 days of half life period in soil.Compare with haloxyfop-P-methyl, the efficient haloxyfop-methyl spirit is structurally with the ethoxyethyl in the methyl substituted haloxyfop-P-methyl; And owing to the a-carbon of propionic acid in the haloxyfop-P-methyl structure is asymmetric carbon atom, so have R and two kinds of optical isomers of S, wherein the S body does not have activity of weeding, and the efficient haloxyfop-methyl spirit is the highly finished product (R body) of having removed non-active portion (S body).It is than haloxyfop-methyl flexibility height under the Isodose, and efficacy stability is subjected to adverse environment condition influence such as low temperature, rainwater few.Behind the medicine after one hour rainfall just very little to drug effect influence.Divide evil, the annual and perennial standing grain herbaceous weed at heading initial stage to arriving behind the seedling, good preventive effect is arranged, invalid to broadleaved herb and nutgrass flatsedge.
Cloransulammethyl, English common name
Cloransulam-methyl, belong to sulfonamido phenacylate class weed killer herbicide, be used for preventing and kill off broad leaved weed, main application sprays for the preceding soil table of plantation, uses to prevent and treat the broad leaved weed in soybean field behind the bud before the bud.
Being mixed of different pesticide species is the common methods of the agriculture resistance disease pest and weed of control.The inventor screens by formulation of pesticide, filters out rational prescription, uses a product can prevent and kill off broad leaved weed and can prevent and kill off grassy weed again, can effectively improve actual preventive effect, reduces dosage, reduces cost, and delays the drug-fast generation of disease pest and weed.The inventor furthers investigate the prescription screening of efficient haloxyfop-methyl spirit and cloransulammethyl, find that efficient haloxyfop-methyl spirit and cloransulammethyl are mixed, in certain mixed ratio scope weeds there are certain synergy or summation action, can prevent and kill off soybean field annual weed effectively.After further study, finished the present invention.
Summary of the invention
Technical problem to be solved: the objective of the invention is to solve in the prior art and can prevent and kill off farmland grassy weed, broad leaved weed problem simultaneously, a kind of wide spectrum, efficient, low toxicity, environmental protection are provided, be conducive to the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention provides this composition pesticide is used for preventing and kill off farmland weed, is particularly useful for preventing and kill off soybean field annual weed.
Technical scheme: the present composition is active ingredient with the efficient haloxyfop-methyl spirit with cloransulammethyl, the efficient haloxyfop-methyl spirit is 10:1～1:10 with the weight fraction ratio of cloransulammethyl, the efficient haloxyfop-methyl spirit is 10%～80% with the percentage by weight of cloransulammethyl weight summation in composition pesticide, and all the other are to allow in the agricultural chemicals to use and the acceptable auxiliary element.
Composition pesticide of the present invention is prepared into known method and is fit to agricultural and goes up any one formulation of using, and reasonable formulation has a kind of in oil-suspending agent, wetting powder, water dispersible granules, effervescent tablet, the aqueous emulsion.The processing technology of the various preparations of the present composition is prior art, can change to some extent according to different situations.
The auxiliary agent that uses in the composition pesticide of the present invention comprises that solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, PH conditioning agent, defoamer, antifreezing agent, packing agent etc. are of value to active ingredient stablizes and bring into play drug effect in preparation known substance, all be the various compositions of using or allow use in the pesticidal preparations always, concrete composition and consumption are determined by testing according to the prescription requirement.
Product described in the invention can finished product preparation form provide, namely each material mixes in the composition, the form that the composition of composition also can single agent provides, and directly mixes in jar or bucket before the use, is diluted to needed concentration then.The frequency of administration of the present composition and amount of application change with weather conditions and weeds situation, can reach the purpose of preventing and kill off by using suitable dosage.
Composition pesticide of the present invention is applicable to prevents and kill off annual weed, especially soybean field annual weed.
Composition pesticide provided by the invention adopts the method for spraying to use usually, also can adopt agricultural to go up other operation techniques of using as required.Chang Yong agricultural chemicals using method for example: spray-on process, powder injection process, pesticide-clay mixture method etc.
Compared with prior art, the invention has the advantages that: 1, composite have tangible synergy or a summation action, improved preventive effect.2, enlarged herbicidal spectrum, a dispenser can be prevented and kill off broad leaved weed can prevent and kill off grassy weed again, time saving and energy saving.3, two kinds of active ingredients are composite, reduced the agricultural chemicals usage amount, reduced cost and to the pollution of environment.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage more short and sweet, the present invention describes with following specific embodiment, but the present invention only limits to these examples absolutely not.The following stated only is the present invention embodiment preferably, only is used for describing the present invention, can not be interpreted as the restriction to scope of the present invention.Should be pointed out that all any modifications of making within the spirit and principles in the present invention, be equal to replacement and improvement etc., all should be included within protection scope of the present invention.
In these embodiments, unless otherwise indicated, all percentages all are weight percentage.
Biologicall test embodiment 1:The efficient haloxyfop-methyl spirit is mixed with cloransulammethyl the synergy of weeds is measured.
Test material: the barnyard grass grass [
