Problems solved by technology

[0002] Fenzazone, the Chinese name is 4-[3-(4,5-dihydroisoxazol-3-yl)-2-methyl-4-methylsulfonyl]-1-methyl-5-hydroxyl -1H-pyrazole is the first benzylpyrazolone herbicide developed by BASF, and also belongs to the inhibitor of p-hydroxyphenylpyruvate dioxygenase (HPPD). The weeds of azines, acetolactate synthase (ALS) inhibitors and acetyl-CoA carboxylase (ACCase) inhibitors have good control effects, and can control the main grass weeds and weeds on corn crops worldwide. Broad-leaved weeds, but the cost of using them alone is high, so it is not conducive to large-scale promotion and use
[0003] The 2-methyl-4-chlorodimethylamine salt is inhaled by the stems and leaves of weeds, inhibits nucleic acid metabolism and protein synthesis at the top of weeds, stops the growth of growth points, and prevents young leaves from stretching until photosynthesis cannot be carried out normally. The lower part of the agent increases the synthesis of nucleic acid and protein in the stem tissue of the plant, promotes abnormal cell division, enlarges the root tip, loses absorption capacity, causes twisting and deformity of the stem, blockage of the sieve tube, damage of the phloem, and obstruction of organic matter transportation, thereby destroying normal plant viability

Abstract

The invention discloses a topramezone-containing herbicide. The topramezone-containing herbicide comprises the effective components: topramezone, terbuthylazine and 2-methyl-4-chlorodimethylamine salt, wherein the weight ratio of topramezone to terbuthylazine to 2-methyl-4-chlorodimethylamine salt is (1-10):(10-20):(30-40). The herbicide provided by the invention is formed by compounding several different active ingredients, and by adopting the herbicide topramezone provided by the invention, the problem of resistance caused by long-term single use can be avoided, and the service life of the herbicide can be prolonged.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide containing fenfentrazone and a preparation method thereof. Background technique [0002] Fenzazone, the Chinese name is 4-[3-(4,5-dihydroisoxazol-3-yl)-2-methyl-4-methylsulfonyl]-1-methyl-5-hydroxyl -1H-pyrazole is the first benzylpyrazolone herbicide developed by BASF, and also belongs to the inhibitor of p-hydroxyphenylpyruvate dioxygenase (HPPD).
