Tillage-free field weed preventing and removing composition

Abstract

The present invention discloses a tillage-free field weed preventing and removing composition, which comprises ammonium glyphosate, chipton, fluoroglycofen and a synergist, wherein a mass ratio of the glyphosate to the chipton to the fluoroglycofen to the synergist is 5-80:1-10:1-5:1-5. The composition is used for preventing and removing tillage-free field annual weeds, and has advantages of significant synergy effect after compounding, weed killing spectrum expanding, weed killing speed improving, significant weed killer consumption reducing and significant reduction of the number of the use of the weed killer.

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...
