Abstract

The Bicao mixture is herbicide composition comprising glyphosate herbicide and pyrazosulfuron-ethyl herbicide in the ratio of 10-150, the glyphosate herbicide may be glyphosate, sodium salt of glyphosate, potassium salt of glyphosate, etc., and the pyrazosulfuron-ethyl herbicide may be pyrazosulfuron-ethyl, isopropylamide salt of pyrazosulfuron-ethyl, ammonium salt of pyrazosulfuron-ethyl, sodium salt of pyrazosulfuron-ethyl, potassium salt of pyrazosulfuron-ethyl, etc. The herbicide composition may be compounded into water preparation, water emulsion, wettable powder, soluble powder, oily suspension, dry suspending, water dispersed granular preparation, granular preparation or tablet. It is used in rice field to kill and prevent weed, and has the features of low labor strength, low dosage, low cost, less environmental pollution, etc.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a composition of glyphosate or its salt and pyrazosulfuron-methyl. It is a herbicide applied in rice fields. The invention provides a pesticide herbicide compound compounded by herbicide glyphosate and pyrazosulfuron-methyl. The composition can expand the control spectrum of herbicides and improve their control effects. One-time application can not only prevent and control the weeds that have been unearthed in the previous rice field, but also control the weeds that have not been unearthed in the next rice field, achieving no-tillage, Reduce labor intensity, reduce the frequency and amount of medication, reduce costs, 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 control...
