Embodiment 1

[0022] Formulation example 1: 80% pretilachlor·pyrimifluor-methyl-pyrazosulfuron-methyl water-dispersible granules.

[0023] Pretilachlor 60%, Pyrimifluben 5%, pyrazosulfuron 15%, sodium dodecylbenzene sulfonate 5%, alkylphenol polyoxyethylene ether 5%, urea 3%, polyvinyl alcohol 2% , Kaolin make up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant, binder and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation and drying , and sieve to obtain 80% pretilachlor·pyrimiflux·pyrazosulfuron-methyl water-dispersible granules.

Embodiment 2

[0024] Formulation example 2: 70% pretilachlor·pyrimifluor-methyl-pyrazosulfuron wettable powder.

[0025] Pretilachlor 50%, pyriflubac-methyl 5%, pyrazosulfuron-methyl 15%, calcium dodecylbenzenesulfonate 10%, alkylphenol polyoxyethylene ether 5%, and diatomaceous earth make up 100%. The above-mentioned active ingredients, wetting agent, dispersant and solid carrier are mixed, mechanically pulverized and then air-flow pulverized, and mixed uniformly to prepare 70% pretilachlor-pyrimifluor-methyl-pyrazosulfuron wettable powder.

Abstract

The invention relates to a weeding composition containing pretilachlor, pyriminobac-methyl and metazosulfuron. The weeding composition comprises the following effective components: pretilachlor, pyriminobac-methyl and metazosulfuron at the ratio of (1-50) to (1-10) to (1-15) in parts by weight. The weeding composition disclosed by the invention has synergetic effects, and can be applied to preventing and removing annual weeds of paddy fields; the effect is obviously superior to that of independent use or binary mixed use of single pesticide; the herbicide controlling spectrum is expanded; meanwhile, the amount of the pesticide is reduced; the environmental pollution is relieved; and the weed resistance is delayed.

Description

technical field [0001] The invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition containing pretilachlor, pyriflux-methyl and pyrazosulfuron-methyl as active ingredients, which is mainly used for controlling annual weeds in paddy fields. Background technique [0002] Preti lachlor: belongs to amide herbicides, the mechanism of action is a cell division inhibitor, suitable for controlling barnyardgrass, bald barnyardgrass, special-shaped sedge, goosegrass, cattle felt, narrow-leaf Alisma, water Annual grass weeds and broad-leaved weeds such as amaranth, heteromorphous sedge, broken rice sedge, clove Polygonum, and bermudagrass. [0003] Pyriminobac-methyl: belongs to pyrimidine salicylic acid herbicides, it can be absorbed through the stems, leaves and roots of weeds, and quickly spread to the whole plant, inhibiting the biosynthesis of acetolactate synthase and amino acids, thereby inhibiting And hinder ...
