Abstract

The invention relates to a composite for preventing and killing off weeds in a cornfield. The composite is prepared from tricornox and 2, 4-D butyl ester. The binary composite can be added with surface active agent, solvent, filling materials and other addition agents to form suspending agent, wettable powder and emulsion. The composite has the outstanding effects of preventing and killing off broad leaved weeds in the cornfield, has no phytotoxicity on hard corn, and is safe to succession crops.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition for controlling broad-leaved weeds in wheat fields, and preparation and application techniques of various dosage forms of the composition. Background technique [0002] According to the national weed census report in the 1980s, there are more than 200 kinds of weeds in wheat fields in my country, and the area of ​​weed damage accounts for more than 30% of the wheat planting area, and the loss accounts for about 15% of the total wheat output, reaching 10 billion kilograms, of which Beef chickweed, swine wormwood, Artemisia soponica, and Dachao are serious hazards. However, with the long-term and large-scale application of herbicides, the problems of weed resistance, population succession and phytotoxicity in chemical weed control in farmland are becoming more and more serious, seriously affecting the high yield and harvest of wheat and the safety of su...
