Synergistic weeding mixture and preparation method thereof

Abstract

The invention discloses a synergistic weeding mixture and a preparation method thereof. The mixture is composed of the following components in parts by mass: 5-15 parts of cycloxydim, 4-8 parts of oryzalin, 6-10 parts of fluchloraline, 2-4 parts of sethoxydim, 6-10 parts of tralkoxydim, 5-7 parts of diclofop-methyl, 4-6 parts of dimepiperate, 4-8 parts of esprocarb, 4-6 parts of fenoxaprop-ethyl, 6-8 parts of quizalofop-ethyl ethyl ester, 4-6 parts of cycloate, 6-8 parts of fenoxaprop-p-ethyl, 7-9 parts of fluazifop-butyl and 5-7 parts of pebulate. The invention also relates to a weeding composition comprising the mixture, the preparation method thereof and an application thereof for preventing and treating undesired plants.

Description

technical field [0001] The invention relates to the field of herbicide technology, in particular to a synergistic herbicide mixture and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, chemical weeding, as a modern and practical technology, plays a huge role in weed control. Although the development of chemical weeding technology is not long, but the development speed is relatively fast. With the development of China's agricultural modernization and the gradual transfer of agricultural labor force, cultivation methods tend to be large-scale and intensive, and the demand for pesticides has increased significantly. Among them, the growth rate of herbicides in recent years is much higher than the development level of insecticides and fungicides, accounting for about 1 / 3 of the proportion of pesticide production. [0003] At present, there are many kinds of herbicides, which can be divided into stem and leaf trea...

AI Technical Summary

Problems solved by technology

However, each herbicide has a specific type of weeds to be controlled, and now there is a lack of herbicide varieties that can selectively control all weeds in the crop growth period. At the same time, long-term use of a single herbicide variety can lead to weeds. Grasses develop resistance or cause changes in weed species and the rapid replacement of weed populations, which greatly increases the difficulty of chemical weeding in farmland. When developing new herbicides, the mixed use of two or more herbicide varieties also came into being
