Problems solved by technology

The medicinal liquid left outside the waxy layer will form crystals when the water evaporates, which is difficult to be absorbed by weeds, and is easily affected by natural conditions such as wind, rain, and sun, and will quickly lose its herbicidal activity

Abstract

The invention relates to special synergistic composition for cyhalofop-butyl. The special synergistic composition is prepared from components in percentage by mass as follows: 0.1%-1% of a polymer, 3%-10% of trisiloxane, 3%-10% of azone and 10%-30% of vegetable oil. The special synergistic composition can be applied to a dispersible oil suspension, and the mass ratio of the special synergistic composition to cyhalofop-butyl is 1:1-1:3. The special synergistic composition has the advantages that pesticide drift is reduced, herbicidal activity of cyhalofop-butyl is improved remarkably, and functions of decrement and synergism are realized.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a special synergistic composition for cyhalofop-methyl and its application in dispersible oil suspension concentrates. technical background [0002] Cyhalofop-ethyl, an aryloxyphenoxypropionic acid herbicide, is highly safe to rice and has good systemic conduction activity. It is absorbed by the leaves and leaf sheaths of plants, conducts through the phloem, and accumulates in the meristem area of ​​plants. By inhibiting acetyl-CoA carboxylase (ACCase), fatty acid synthesis is stopped, and cell growth and division cannot proceed normally. Membrane system The lipid-containing structure is destroyed, and finally leads to the death of weeds. In recent years, the damage of D. japonicus in direct-seeding paddy fields has become increasingly serious, and has a greater impact on rice yield. If the harm cannot be continuously and effectively controlled, it will directly threaten th...
