Abstract
The invention relates to a weeding composition containing rimsulfuron and triazine. The weeding composition contains an active component A, an active component B, auxiliaries and other excipients, wherein the active component A is rimsulfuron, and the active component B is one compound selected from metribuzin and terbutryn. The weeding composition is characterized by comprising 1-60wt% of the active component A and 1-80wt% of the active component B; the weeding composition can be prepared into a wettable pulvis, a water dispersible granule, a suspending agent, a suspend emulsion formulation and a micron emulsion for controlling corn weeds, and has characteristics of pesticide drug dose reduction, pesticide residual reduction, good environmental compatibility and safety for human and livestock.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations containing rimsulfuron and triazines, for control of maize 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, make the agricultural chemicals of performance complement obtain 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.Their herbicide ability and scope are also different, and some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate other weed killer herbicide and be difficult to the weeds of eliminating.Therefore, the composite mixed important directions that also becomes domestic and international research new herbicides of weed killer herbicide, 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, work out a series of Herbicidal compositions, obtained greater advance.
My company is also devoted to the research and development of Herbicidal compositions.At present, have no report about rimsulfuron to the relevant composite product of piperazine humulone, terbutryn.
Summary of the invention
The object of this invention is to provide a kind of Herbicidal combinations containing rimsulfuron and triazines of control of maize field weed.
Technical scheme of the present invention is:
