Problems solved by technology

In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance; at the same time, due to the complex grass phase and various types of weeds in the field, such as grass weeds, sedge weeds Mixed with broad-leaved weeds, etc., the use of a single species of herbicide can no longer effectively solve the above problems, and all will show some defects

Embodiment 1

[0022] Example 1: 60% pyrimifen·oxadiazone·azisulfuron-methyl water dispersible granules.

[0023] 10% pyrimifen, oxadiazon 25%, azinpyrazosulfuron 25%, sodium dodecylbenzene sulfonate 5%, methylenebisnaphthalene sulfonate sodium formaldehyde condensate 5%, bentonite 3% , 2% of hydroxypropyl cellulose, and 100% of attapulgite. Mix the above-mentioned active ingredients, wetting agent, dispersing agent, disintegrating agent, binder and solid carrier evenly, pulverize with a superfine jet mill, knead, and then add it into a fluidized bed granulation dryer for granulation and drying. , sieving, and 60% pyrimifen·oxadiazone·aziosulfuron-methyl water dispersible granules can be prepared.

Embodiment 2

[0024] Example 2: 53% pyrimifen·oxadiazone·promethazine water dispersible granules.

[0025] 10% pyrimifen, oxadiazon 25%, rimsulfuron 18%, alkylnaphthalene sulfonate 5%, sodium polyacrylate 10%, bentonite 3%, hydroxypropyl cellulose 2%, Attapulgite topped up to 100%. Mix the above-mentioned active ingredients, wetting agent, dispersing agent, disintegrating agent, binder and solid carrier evenly, pulverize with a superfine jet mill, knead, and then add it into a fluidized bed granulation dryer for granulation and drying. , and sieving to obtain 53% pyrimifen·oxadiazone·promethazine water dispersible granules.

Embodiment 3

[0026] Example 3: 80% pyrimifen·oxadiazone·azisulfuron-methyl wettable powder.

[0027] Syrup 20%, oxadiazon 40%, azinpyrazosulfuron 20%, calcium dodecylbenzenesulfonate 10%, alkylphenol polyoxyethylene ether formaldehyde condensate 5%, light carbonic acid 100% calcium supplement.

Abstract

The invention discloses pesticide composition containing pyriminobac-methyl, oxadiargyl and sulfonylurea herbicide. A mass ratio of pyriminobac-methyl to oxadiargyl to the sulfonylurea herbicide is (1-20): (1-50): (1-50); the sulfonylurea herbicide is selected from one of metazosulfuron or propyrisulfuron. The pesticide composition is applicable to control of weeds in paddy fields; compared with single dose or binary combination use, the pesticide composition improves the weeding effect remarkably and expands the weed control spectrum, meanwhile, the usage amount of pesticide is reduced, the environmental pollution is reduced, the weed resistance is delayed, and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide composition and the application field thereof, in particular to a pesticide composition using pyrimifen, oxadiazon and sulfonylurea herbicides as active ingredients, which is mainly used for controlling weeds in paddy fields . Background technique [0002] Pyriminobac-methyl: belongs to pyrimidine salicylic acid herbicides, it can be absorbed through the stems, leaves and roots of weeds, and quickly transmitted to the whole plant, inhibiting the biosynthesis of acetolactate synthase and amino acids, thereby inhibiting the And hinder the cell division in the weeds, so that the weeds stop growing, and eventually the weeds turn white and die. It has special effects on rice field barnyardgrass and is extremely safe for rice. [0003] Oxadiargyl: It belongs to the oxadiazolone class of herbicides, and its mechanism of action is an inhibitor of protoporphyrinogen oxidase. It can be used in paddy fields to control annual...
