Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains effective constituents A pyrrole grass ether and active ingredient B, be used to prevent and treat soybean and paddy 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 ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present 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 valid approach, make the agricultural chemicals of performance complement obtain best synergistic effect through the proportioning of adjusting different agricultural chemicals.

3, relative molecular mass 447.8 is the diphenyl ether herbicides by Rhom and Hass's exploitation.Fluoroglycofen-ethyl is a proporphyrinogen oxidase inhibitor.In case by plant absorbing, only under illumination condition, just performance is renderd a service.This compound reacts with mol-chloric, generates the tetrapyrrole that plant cell is had toxicity, gathers and has an effect.Gather in the process, make the plant cell membrane complete obiteration, cause the cell inclusion seepage then.Finally cause weeds dead.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
There is the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch from nineteen fifty-five, 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.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of acifluorfen, fluoroglycofen-ethyl or fomesafen about pyrrole grass ether.
