Problems solved by technology

[0002] 2-Ethyl-N-(ethoxymethyl)-α-chloroacetanilide, commonly known as Kechor, belongs to one of the amide herbicides, and the mechanism of herbicide is to inhibit the protein synthesis of sensitive plants , used for soil treatment, as a selective pre-emergence herbicide, EC, wettable powder, and suspending agent prepared from crude oil can be used in rice transplanting fields, soybeans, corn, peanuts and other crop fields, mainly to control cattle felt, barnyardgrass and dog But the herbicidal spectrum is limited, and the control effect on common broad-leaved weeds in farmland such as amaranth, purslane, cocklebur, dawanhua, etc. is not ideal
In addition, some herbicides have a good control effect on broad-leaved weeds, but the effect on annual grass weeds is not ideal. If you want to control weeds comprehensively, it is labor-intensive to apply one by one, and the dosage is large. Relatively large, great harm to crops, high cost

Abstract

The present invention relates to composite agricultural chemicals, and is one kind of herbicide composition containing ethachlor and one other herbicide. The composition has effective component accounting for 1-90 wt% of the total weight. It has wide herbicidal spectrum, improved herbicidal property, less environmental pollution and low production cost, and may be used in preventing and killing the monocotyledonous weeds and dicotyledonous weeds in farm land.

Description

(1) Technical field [0001] The present invention relates to a pesticide composition, especially a farmland herbicide composition. (2) Background technology [0002] 2-Ethyl-N-(ethoxymethyl)-α-chloroacetanilide, commonly known as Kechor, belongs to one of the amide herbicides, and the mechanism of herbicide is to inhibit the protein synthesis of sensitive plants , used for soil treatment, as a selective pre-emergence herbicide, EC, wettable powder, and suspending agent prepared from crude oil can be used in rice transplanting fields, soybeans, corn, peanuts and other crop fields, mainly to control cattle felt, barnyardgrass and dog But the herbicidal spectrum is limited, and the control effect on common broad-leaved weeds in farmland such as amaranth, purslane, cocklebur, and dawanhua is not ideal. In addition, some herbicides have a good control effect on broad-leaved weeds, but the effect on annual grass weeds is not ideal. If you want to control weeds comprehensively, it ...
