High-concentration dimethyl tetrachloro dimethylamine brine agent and preparation method thereof

Abstract

The invention discloses a high-concentration dimethyl tetrachloro dimethylamine brine agent and a preparation method thereof. The key point of the technical scheme thereof is that the brine agent contains the following components in parts by weight: 60-70 parts of 2-methyl-4-chlorophenoxyacetic acid, 30-40 parts of 40% dimethylamine and 0.5-5.5 parts of modified tea saponin. The dimethyl tetrachloro dimethylamine salt associated complex is formed after 2-methyl-4-chlorophenoxyacetic acid reacts with dimethylamine, and then the modified tea saponin is added, so that the affinity of the 2-methyl-4-chlorophenoxyacetic acid, the dimethylamine and the plant surface is enhanced, the contact angle between the brine agent and the stem leaf surface is reduced, the wetting function of the brine agent and the stem leaf surface is benefited and the brine agent is suitable for an environment with relatively low temperature.

Description

technical field [0001] The invention relates to a pesticide herbicide, in particular to a high-concentration dimethyltetrachlorodimethylamine salt solution and a preparation method thereof. Background technique [0002] Dimethyltetrachloride is a selective herbicide of dimethyltetrachloride and phenoxycarboxylic acid. It has strong systemic conductivity. It is mainly used for post-emergence stem and leaf treatment. The agent passes through the cuticle and cytoplasmic membrane, and finally conducts to Each part has different effects on nucleic acid and protein synthesis in different parts, and inhibits nucleic acid metabolism and protein synthesis at the top of the plant, so that the growth point stops growing, and the young leaves cannot be stretched until photosynthesis cannot be carried out normally; it is transmitted to the lower part of the plant The chemical agent increases the synthesis of nucleic acid and protein in the stem tissue of plants, promotes abnormal cell di...

[0002] Dimethyltetrachloride is a selective herbicide of dimethyltetrachloride and phenoxycarboxylic acid. It has strong systemic conductivity. It is mainly used for post-emergence stem and leaf treatment. The agent passes through the cuticle and cytoplasmic membrane, and finally conducts to Each part has different effects on nucleic acid and protein synthesis in different parts, and inhibits nucleic acid metabolism and protein synthesis at the top of the plant, so that the growth point stops growing, and the young leaves cannot be stretched until photosynthesis cannot be carried out normally; it is transmitted to the lower part of the plant The chemical agent increases the synthesis of nucleic acid and protein in the stem tissue of plants, promotes abnormal cell division, enlarges the root tip, loses the ability to absorb nutrients, causes the stem to be twisted and deformed, the sieve tube is blocked, the phloem is damaged, and the transportation of organic matter is blocked, thereby Destroys the normal viability of plants, eventually leading to plant death

[0007] But, when most of the herbicides containing dimethyltetrachloride in the prior art were used under low temperature environment, after the herbicide was applied to the paddy field, the wettability of the herbicide on the stem and leaf was poor, which had a strong impact on the performance of the herbicide. drug effect
