[0010] At present, herbicides in wheat fields are limited by the safety of crops, and the herbicidal spectrum is also limited. The use of a single herbicide alone cannot completely effectively control the occurrence of weeds in wheat fields. Moreover, some herbicides have too long duration in the field. , Excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract
The invention discloses a mixed herbicide containing clodinafop-propargyl and procarbazone sodium. According to the herbicide, the clodinafop-propargyl and the procarbazone sodium are taken as main effective components, and the mass ratio of the clodinafop-propargyl to the procarbazone sodium is 1:(4-18). The mixed herbicide disclosed by the invention has a significant effect in application of weeding in a wheat paddock, particularly an application thereof in preventing and removing various graminaceous and broadleaved weeds in the wheat paddock. Compared with a single dosage, by adopting the herbicide disclosed by the invention, the weed resistance is delayed under the premise that the pesticide effect is improved, and the mixed herbicide is wide in weed control spectrum, long in lasting period, and has safety on wheat and after-reap crops.
Description
technical field [0001] The present invention relates to a herbicide. Background technique [0002] Wheat is one of the most important grain resources in the world, and its output is second only to rice, ranking second. It is not only the main food resource for human beings, but also an important industrial raw material. However, the harm of weeds in wheat fields has always been an important factor affecting the high quality and high yield of wheat. At present, the main weeds that harm wheat fields are: Japanese kannada, Chinese kannada, wild oats, Miscanthus, bluegrass, chrysanthemum, Chickweed, geranium, mother-in-law, big and small nest vegetables, shepherd's purse, wild pickled vegetables, lacquer, small thorns, etc. In recent years, with the changes in planting systems and cultivation management, some new weed species and some non-agricultural weeds have developed rapidly in wheat fields, and some new weed communities have been or are forming. On the one hand, the use ...
