Weeding composition containing ametryn and acetochlor

Abstract

The invention relates to a weeding composition containing ametryn and acetochlor. The pesticide composition comprises active ingredients and synergistic auxiliaries, wherein the active ingredients include 10-50 parts by weight of ametryn and acetochlor with a weight ratio of 10:(1-100); and the synergistic auxiliaries include 5-10 parts by weight of salicylic acid and chitosan with a weight ratio of 10:(1-10). The pesticide composition is used for ensuring the synergism of the herbicides as well as prolonging the effective period of weeding.

Description

technical field

[0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a herbicidal composition comprising ametryn and acetochlor, in particular to a herbicidal composition comprising ametryn and acetochlor, and also comprising salicylic acid and chitosan Herbicidal pesticide composition. Background technique

[0002] Ametryn is a triazine herbicide, also known as "atrazine", which is insoluble in water but easily soluble in organic solvents, and it is decomposed into 6-6 - Hydroxy derivatives.

[0003] Acetochlor is an amide systemic broad-spectrum herbicide, mainly used to control weeds in non-cultivated areas. It can be used to control crabgrass, goosegrass, foxtail, etc. in the fields of cotton, soybean, sorghum, and corn.

[0004] The combination of ametrazin and acetochlor showed a synergistic effect on some weeds, but for most weeds, it only expanded the function of acetochlor and failed to achieve an effective synergistic...
