Abstract
The invention relates to a weeding composition containing florasulam and thifensulfuron, which is mainly characterized by comprising 1 percent to 60 percent of florasulam and 1 percent to 80 percent of thifensulfuron of active components and the rest of addition agent, and can be made into wettable powder, water dispersion granule, suspending agent, suspending emulsion, micro-emulsion, emulsion in water and the like. The weeding composition is used for preventing and curing broad-leaf weed and grassy weed in cornfields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations containing florasulam and thifensulfuronmethyl, for preventing and treating cornfield gramineae weed and broad leaved weed.
Background technology
Nineteen fifty-five has people to report that Amrol can increase dalapon the effect of preventing and kill off of stone thatch is started, after, along with further developing that weed killer herbicide is produced and applied, using with between weed killer herbicide grows up gradually.China also comparatively payes attention to aspect the mixed research of weed killer herbicide, is extensively recognized as one of important measures of rationally use of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained greater advance.
