Problems solved by technology

2-methyl-4-chloride and its salts or esters are an important class of herbicides used to control broad-leaved weeds in wheat fields in my country. They have many advantages such as wide herbicidal spectrum, long-lasting effect, thorough effect, and are not easy to produce drug resistance. However, , because its mechanism of action is to destroy the balance of plant hormones, so the drug effect is slow, the quick effect is poor, and there are also shortcomings such as easy to produce phytotoxicity to broad-leaved crops. Effective composition, in order to improve its quick-acting performance, improve the control effect on weeds, reduce the dosage of 2-methyl-4-chloride and its salt or ester at the same time, reduce the risk of its phytotoxicity, and ensure the safety of wheat production

Embodiment 1

[0057] Example 1: 36% lactofen-2-methyl-4-chloride emulsifiable concentrate

[0058] Raw materials and dosage: 1% lactoforin, 35% methacrylic acid, 44% xylene, 10% calcium dodecylbenzenesulfonate, 10% nonylphenol polyoxyethylene ether.

[0059] The preparation method is as follows: add lactofen-methyl technical substance, 2-methyl-4-chlorine technical substance, calcium dodecylbenzenesulfonate, and nonylphenol polyoxyethylene ether to xylene in turn under stirring, and fully stir to prepare Single-phase transparent liquid, filtered to remove impurities.

Embodiment 2

[0060] Example 2: 26% lactofen-2-methyl-4-chloride emulsifiable concentrate

[0061] Raw materials and dosage: 1% lactoforin, 25% methacrylic acid, 54% toluene, 9% calcium dodecylbenzenesulfonate, 11% octylphenol polyoxyethylene ether.

[0062] The preparation method is as follows: adding lactofen-alifop active drug, 2-methyl-4-chlorine active drug, calcium dodecylbenzenesulfonate, and octylphenol polyoxyethylene ether to toluene in turn under stirring, and fully stirring to prepare a single Phase transparent liquid, filtered to remove impurities.

Embodiment 3

[0063] Example 3: 39% lactofen-2-methyl-4-chloride sodium wettable powder

[0064] Raw materials and dosage: lactoforin 3%, sodium 2-methyl-4-chloride 36%, pull-off powder 6%, sodium lignosulfonate 8%, ethylene oxide-propylene oxide block copolymer 1%, white Carbon black makes up the balance.

Abstract

The invention relates to a weeding composition containing lactofen and chipton herbicide and application of the weeding composition.The weeding composition comprises active components including lactofen and chipton herbicide preferentially according to the weight ratio of 1:(1-50).The weeding composition has a remarkable synergistic effect, good fast-acting property and low toxin to human and livestock; in addition, lactofen and chipton herbicide have different acting mechanisms, the drug resistance of weeds can be delayed, and the weeding composition is an ideal herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition containing lactofen-methyl as an active ingredient and a 2-methyl-4-chlorine herbicide as an active ingredient and its application in preventing and controlling agricultural weeds. Background technique [0002] Wheat is the third largest grain crop in my country after corn and rice, accounting for more than 20% of the country's total grain output. Therefore, ensuring continuous and high yields of wheat is of great significance for maintaining my country's grain self-sufficiency rate and ensuring national food security. However, wheat production faces numerous threats, among which weeds are one of the most important factors. According to reports, the area of ​​weed damage in my country's wheat fields accounts for more than 55% of the planting area, of which the severely damaged area accounts for 28%, and the yield loss reaches 15%. Hazards have become a...
