A composition for controlling weeds in no-tillage fields

Abstract

The invention discloses a composition for controlling weeds in a no-tillage field. The herbicidal composition includes glyphosate ammonium salt, 2-methyl-4-chloride, acifluorfen and a synergist, and the glyphosate ammonium salt , 2-methyl-4-chloride, acifluorfen and the synergist have a mass ratio of 5 to 80:1 to 10:1 to 5:1 to 5. The composition is used to prevent and control annual weeds in no-tillage fields, and has the advantages of obvious synergistic effect after compounding, expanding the herbicide spectrum, increasing the weeding speed, and significantly reducing the amount and frequency of use of herbicides.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a composition for controlling weeds in no-tillage fields composed of ammonium glyphosate, 2-methyl-4-chloride and acifluorfen. Background technique [0002] With the development of technology, in order to protect soil, water and environment, no-tillage technology has been developed rapidly, saving time and effort. No-till means that the soil is not disturbed except for seeding or infusing fertilizers. Fertilizer can be carried out at the same time as sowing, or before sowing or after emergence, and can be applied to the soil or sprinkled on the surface. However, mechanical weeding and intertillage are not carried out during the process management, and crop residues are left on the surface after harvest to prevent soil erosion. However, in the process of practical experience, it is also concluded that "no tillage without weeding is tantamount to doing no...
