Problems solved by technology

[0004] The long-term use of chemical agents alone is likely to cause the emergence of weed resistance and pollute the environment. Finding synergistic compositions that can improve the weeding effect and reduce the dosage of active ingredients is the research and development focus of many domestic pesticide companies
In the prior art, there is no relevant report on the compound use of trifluralin and pretilachlor

Abstract

The invention provides a herbicidal composition containing trifluralin and pretilachlor. The active ingredients of the herbicidal composition comprise trifluralin and pretilachlor, and the mass ratioof trifluralin to pretilachlor is (5-30): (1-15). The herbicidal composition disclosed by the invention can be used for preventing and removing annual weeds in a crop field and has a remarkable synergistic effect.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicidal composition comprising trifluralin and pretilachlor and application thereof. Background technique [0002] Trifluralin is a selective aniline pre-emergence soil treatment agent, which is mainly absorbed through the coleoptile and hypocotyl of weeds, affects the production and transmission of hormones, inhibits cell division and causes weeds to die. Trifluralin has no effect on the weeds that have been unearthed, and the weeds will be killed only when they absorb the agent during the unearthed process after the weed seeds germinate. Trifluralin can effectively control annual grass weeds and some broad-leaved weeds with small seeds, and has a long duration. [0003] Pretilachlor is a selective pre-emergence treatment agent, mainly absorbed by plant hypocotyls, mesocotyls and coleoptiles, and slightly absorbed by roots, directly interferes with protein synthesis i...
