Abstract
The invention relates to a herbicidal composition containing carfentrazone-ethyl and bromoxynil. The composition is mainly characterized by containing the effective components of 1-60% of carfentrazone-ethyl, 1-80% of bromoxynil, and the balance auxiliary agents and other excipients and can be prepared into the forms of wettable powder, water dispersible granule, suspending agent, suspending emulsion, microemulsion and emulsion in water, etc. The herbicidal composition of the invention can be used for controlling broadleaf weeds and sedges.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains azoles humulone and Brominal, be used to prevent and treat broad leaved weed and nutgrass flatsedge.
Background technology
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.
