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: 30% propargyl oxadiazone·pretilachlor·pentoxsulam water dispersible granules.

[0042] Propyryl oxadiazone 8%, pretilachlor 20%, penoxsulam 2%, sodium dodecylbenzene sulfonate 5%, alkylphenol polyoxyethylene ether sulfate 10%, ammonium sulfate 2%, Kaolin makes up 100%. 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. 30% propargyl oxadiazone · pretilachlor · penoxsulam water dispersible granules can be obtained.

Embodiment 2

[0043] Example 2: 70% propargyl oxadiazone · pretilachlor · penoxsulam wettable powder.

[0044] Propyryl oxadiazone 15%, pretilachlor 50%, penoxsulam 5%, sodium lauryl sulfate 8%, alkylphenol polyoxyethylene ether sulfate 6%, diatomaceous earth make up 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent and solid carrier, mechanically pulverize, then airflow pulverize, and mix evenly to obtain 70% propargyl oxadiazone, pretilachlor, penoxsulam wettability powder.

Embodiment 3

[0045] Example 3: 25% propargyl oxadiazone·pretilachlor·pentoxsulam oil suspension concentrate.

[0046] Propyloxadiazone 4%, Pretilachlor 20%, Penoxsulam 1%, Fatty Acid Ester Sulfate 10%, Sodium Dodecyl Benzene Sulfonate 10%, Hydroxymethyl Cellulose 2%, Oil Methyl 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, and 25% propargyl oxadiazone·propipazone can be prepared Amine Penoxsulam Oil Suspension Concentrate.

Abstract

The invention discloses a weeding composition containing oxadiargyl. The weeding composition comprises effective components consisting of oxadiargyl, pretilachlor and penoxsulam, with the balance being auxiliary components permitted and acceptable in pesticides, wherein a weight ratio of oxadiargyl to pretilachlor to penoxsulam is 1-50: 1-80: 1-40, and the total weight percentage content of oxadiargyl, pretilachlor and penoxsulam in the composition is 0.1 to 85%. The composition exerts obviously better effects in preventing and eliminating annual weeds in the paddy field compared with separately used effective components of the composition, has a broadened weed control spectrum, reduces drug dose, delays generation of drug resistance of weeds and mitigates pollution to the environment.

Description

technical field [0001] The present invention relates to a pesticide herbicidal composition and its application field, specifically a ternary compound compounded with propargyl oxadiazone, pretilachlor and penoxsulam as active ingredients, which is applied to annual weeds in paddy fields prevention and treatment. 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] Oxadi...
