Abstract

The invention discloses a composite herbicide and a preparation method thereof. The preparation method comprises the following steps: mixing and compounding 2, 4-D butyl ester, metribuzin, pendimethalin, a phenoxy herbicide and an assistant to obtain the composite herbicide. The problem that a traditional corn field herbicide is incomplete in weeding type and poor in weeding effect is solved.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a compound herbicide and a preparation method thereof. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Corn is the third largest food crop in my country. The weeds growing in the corn field will seriously affect the growth and yield of corn. However, the traditional herbicides in the corn field have the problems of incomplete weed killing and poor weeding effect. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a compound herbicide with comprehensive herbicide types and excellent herbicidal effect and its preparation method. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a compound herbicide and its preparation method, which solves the...
