Abstract

A composite herbicide for corn field contains phenyloxyacetic acid kind of herbicide chosen from 2,4-D sodium, MCPA, MCPA sodium, 2,4-D butylate, etc, and sulfonylurea kind of herbicide chosen from nicosulfuron, rimsulfuron, etc in weight ratio of (1-80):1. The preparation is wattable powder and soluble powder.

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 phenoxyacetic acid and sulfonylurea 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 herbicide combination can expand the herbicidal spectrum. [0003] Most of the phenoxyacetic acid herbicides are hormone-type systemic herbicides, such as 2M4Cl or 2M4Cl sodium salt, which have strong physiological activity on weeds, causing weeds to appear deformed and even die. It has obvious...
