Herbicide containing benzobicylon and 2-methyl-4-chloro-isooctyl

Abstract

The invention relates to a herbicide containing benzobicylon and 2-methyl-4-chloro-isooctyl, the active ingredients of the herbicide are benzobicylon and 2-methyl-4-chloro-isooctyl, wherein the mass ratio of the benzobicylon to the 2-methyl-4-chloro-isooctyl is (1-10): (0.1-1.5); the herbicide containing benzobicylon and 2-methyl-4-chloro-isooctyl is in the form of a suspending agent and is prepared from 5%-85% of active ingredients, 5%-15% of auxiliaries and 10%-80% of deionized water, wherein the auxiliaries are polyoxyethylene ether sulfate, a stabilizer, a thickening agent, an organic silicon defoaming agent and ethylene glycol. The synthesized polyoxyethylene ether sulfate is used as a wetting dispersant, and the excellent wetting performance, solubilizing performance and emulsifying power of the wetting dispersant are utilized, so that the problem that the effect is reduced due to caking, layering and precipitation caused by long-term storage of the herbicide suspending agent is solved, and the long-term stability of the herbicide suspending agent is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide containing bicyclic sulcotrione and dimethyltetrachloroisooctyl. Background technique [0002] Bicyclic sulcotrione is a herbicide with broad-spectrum selectivity and long-lasting effect for controlling weeds in direct-seeded rice fields and transplanted fields. Bicyclic sulcotrione has a bicyclic and phenylene sulfide structure, and has strong soil adsorption properties. It is an inhibitor of p-hydroxyphenylpyruvate dioxygenase (HPPD), which affects the synthesis of plastoquinone by inhibiting HPPD. Phytoquinone acts on phytoene dehydrogenase (PDS), which ultimately affects the biosynthesis of carotenoids and causes leaf whitening. It is characterized by a long duration. [0003] Dimethyltetrachloroisooctyl is synthesized from dimethyltetrachloroisooctyl ester and isooctanyl ester. It is a selective hormone herbicide with strong systemic conductivity...

AI Technical Summary

Problems solved by technology

[0003] Dimethyltetrachloroisooctyl is synthesized from dimethyltetrachloroisooctyl ester and isooctanyl ester. It is a selective hormone herbicide with strong systemic conductivity. It is mainly used for post-emergence stem and leaf treatment. The agent penetrates cutin layer and cytoplasmic membrane, suitable for broad-leaved weeds and sedge weeds, such as kohlrabi, quinoa, sedge, amaranth, purslane, cocklebur, spinach, solanum nigrum, sedge, wattle, Cow felt, but it has no effect on grass weeds, and the efficacy will be greatly reduced in the environment below 18°C

[0004] With the continuous use of pesticides, target crops are likely to develop resistance, and the effective dose of pesticides will gradually increase, and the environmental and food safety problems caused by pesticide residues will become increasingly serious
