Abstract

The herbicide composition contains symmetrical triazine herbicide atrazine, simazine or propazine; amide herbicide acetachlor, butachlor, propisochlor or metoachlor; and paraquat in the ratio of 1-10 to 1-10 to 1. The herbicide composition may be compounded into water suspension, wettable powder, oil suspension, dry suspension, water dispersed granulated preparation, granulated preparation or tablet. The herbicide composition may be used directionally in preemergence or postemergence stage in corn field, sugar cane field, etc.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a herbicide composition. The invention provides a pesticide herbicide composition compounded by s-triazines, amides and paraquat herbicides. The composition can expand the control spectrum of herbicides, improve their control effect, reduce dosage, reduce cost and reduce environmental pollution. Background technique [0002] Due to competing with crops for glory, fertilizer, and water, farmland weeds cause great losses to crop production every year. At present, the main method for preventing and controlling farmland weeds is to spray pesticides and herbicides. The formulated herbicide composition can expand the herbicidal spectrum. [0003] Triazine herbicides (such as atrazine) are systemic and conductive pre- and post-emergence herbicides, which kill weeds by interfering with plant photosynthesis; amide herbicides (such as acetochlor) are internal Absorp...
