Problems solved by technology

[0008] The purpose of the present invention is to solve the problems in the prior art that when a single pesticide is used alone, it is easy to produce resistance to weeds in paddy fields and the actual control effect is poor, and to provide a high-efficiency, broad-spectrum, economical, safe, and beneficial to paddy fields. Herbicidal composition for integrated weed management

Embodiment 1

[0041] Example 1: 60% propargyl oxadiazone·pyrimifluben·mesotrione water-dispersible granules.

[0042] 20% clomazone propargyl, 10% pyrimifluben, 30% mesotrione, 8% sodium butyl naphthalene sulfonate, 10% alkylphenol polyoxyethylene ether, 2% ammonium sulfate, and 100% kaolin. Mix the above-mentioned active ingredients, dispersant, wetting agent, disintegrant and solid carrier evenly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving. 60% propargyl oxadiazone·pyrimifluben·mesotrione water dispersible granules can be obtained.

Embodiment 2

[0043] Example 2: 80% propargyl oxadiazone·pyrimifluben·mesotrione wettable powder.

[0044] 30% propargyl oxadiazone, 10% pyrimifluben, 40% mesotrione, 8% sodium lauryl sulfate, 5% alkylphenol polyoxyethylene ether sulfate, diatomaceous earth supplement 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent and solid carrier, mechanically pulverize, then airflow pulverize, and mix evenly to obtain 80% propargyl oxadiazone · pyrimifluoride · mesotrione wettable powder .

Embodiment 3

[0045] Example 3: 20% propargyl oxadiazone·pyrimifluben·mesotrione oil suspension concentrate.

[0046] Propyryl oxadiazone 6%, pyrifluzan 3%, mesotrione 11%, lignosulfonate 10%, sodium dodecylbenzene sulfonate 10%, hydroxymethylcellulose 1.5%, oleic acid Ethyl esters make up 100%. After the above-mentioned active ingredients and additives are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system is formed in a non-aqueous medium to prepare 20% propargyl oxadiazone. Ether Mesotrione Oil Suspension Concentrate.

Abstract

The invention discloses herbicide composition containing mesotrione. The herbicide composition comprises effective components, namely, oxadiargyl, pyriminobac-methyl and the mesotrione, wherein the weight ratio of the oxadiargyl to the pyriminobac-methyl to the mesotrione is in a range of (1-50):(1-40):(1-60), the total weight of the oxadiargyl, the pyriminobac-methyl and the mesotrione accounts for 0.1-85% of the weight of the composition, and the rest are assistant components allowed to be used and acceptable in pesticides. The composition is obviously better than exclusive use of various single agents in prevention and killing off effects on annualweeds in paddy fields, the herbicide controlling spectrum is expanded, meanwhile, the dosage is reduced, the drug resistance of the weeds is delayed, and the pollution to the environment is reduced.

Description

technical field [0001] The present invention relates to a pesticide herbicidal composition and its application field, in particular to a ternary compound compounded with propargyl clomazone, pyrizaflun and mesotrione as active ingredients, which is applied to the production of annual weeds in paddy fields prevention. Background technique [0002] Chemical weeding is one of the main means to control farmland weeds in agricultural production. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. Simultaneously, because weeds occur when the grass phase is complex and there are many types, the use of a single species can no longer effectively solve the damage caused by weeds in farmland, and all will show a certain aspect of defects. The mixed use of different types of herbicides has many advantages such as broad weeding spectrum, improved control effect, delay of weed resistance, saving time and labor. [0003] ...
