Abstract
The invention relates to a weeding composition containing florasulam and pinoxaden. The composition is mainly characterized by containing 1 to 60 percent of florasulam serving as an active ingredient, 1 to 60 percent of pinoxaden, auxiliary agent and other excipient; and the weeding composition can be prepared into wettable powder, water dispersible granules, suspending agent, emulsion, micro emulsion, emulsion in water or the like. The weeding composition is used for preventing and controlling broadleaf weed and gramineous weed in wheat fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations containing florasulam and azoles quinoline grass ester, 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.
