Composite weedicide

Abstract

The invention discloses a composite weedicide. The composite weedicide comprises a mixture of 95 percent fluroxypyr and 97.4 percent carfentrazone serving as effective ingredients; and the range of the weight ratio of the 95 percent fluroxypyr to the 97.4 percent carfentrazone is between 1:99 and 99:1. The invention also discloses a plurality of preparation formulations of the composite weedicide. In the invention, the 95 percent fluroxypyr and the 97.4 percent carfentrazone are compounded and mixed to serve as a wettable powder preparation, which can give play to the comprehensive advantages of the two medicaments. The composite weedicide can not only achieve the effect of weeding rapidly and radically, but also reduce the dosage and facilitate the use of a peasant. The harm of various broad leaf weeds in a paddy field, a wheat field and a corn field can be prevented by using the weedicide once; therefore, the dosage of the weedicide in the paddy field, the wheat field, the corn field and the like can be reduced; and the prevention and removal effects on noxious weeds can be improved.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular, the invention relates to a herbicide; more specifically, the invention is a combined herbicide. Background technique

[0002] Wheat fields, rice fields, and corn fields are large food crops in my country, but the development of combined herbicides is very slow. The used mefentrazone is an azole herbicide, and mefentrazone inhibits protoporphyrin oxidase, thereby causing membrane splitting. It is used on cereal crops for post-emergence foliar treatment, so that sensitive broad-leaved weeds will be blocked and quickly dry up and die. It is safe for cereal crops such as wheat and corn. It has special effects on the weeds resistant to the long-term use of sulfonylurea herbicides, and is safe for subsequent crops. Fluroxypyr is a systemic conduction postemergence herbicide. After the drug is quickly absorbed by the plants, the sensitive plants will respond to typical hormone herb...
