Abstract
The invention relates to a weeding composition containing carfentrazone-ethyl and triazine. The weeding composition is mainly characterized by containing 1-60 percent of active ingredient A, 1-80 percent of active ingredient B, and aid and other excipients, wherein the active ingredient A is carfentrazone-ethyl; the active ingredient B is selected from atrazine or terbutryn; and the composition can be prepared into wettable powder, water dispersible particles, a suspending agent, a suspending emulsion and the like. The weeding composition can be used for preventing and controlling weeds in wheat paddocks and corn fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to one and contain azoles humulone and triazines Herbicidal combinations, for preventing and treating wheat paddock and corn field weed.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", (1) is safe, and this not only requires toxicity low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of effectively approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by adjusting the proportioning of different agricultural chemicals.

The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds that are difficult to elimination with other weed killer herbicide.
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.
My company is also devoted to the research and development of Herbicidal compositions.At present, have no report about azoles humulone to the relevant composite product of atrazine, terbutryn.
