Abstract
The invention relates to a herbicide composition containing pyraflufen-ethyl (1), at least one systemic and/or contact herbicide nicosulfuron and mesotrione. The herbicide composition has obvious effects of a grass killing spectrum enlargement and synergy.
Description
Technical field:
The present invention relates to chemistry and biochemistry, pyrrole grass ether with some in the herbicidal composition formed of absorption and/or contact herbicide because its structure is different and action target different, thus to herbicidal effect generation generation difference.
Background technology:
Pyrrole grass ether is a contact killing type weed killer herbicide, is proporphyrinogen oxidase inhibitor, and weeds such as clearvers, deaf nettle, chickweed, Arabic Veronica are had good killing effect.Patent EP 93-116635 has introduced pyrrole grass ether and organophosphorus herbicide and has used the effect of using with as glyphosate, cremart etc. with.Patent EP 94-420142 has introduced the drug effect that pyrrole grass ether and Diflufenican, Brominal, flurtamone, aclonifen, isoproturon are used with, and it is good, single with then poor to show that pyrrole grass ether and aclonifen are used preventive effect with.Introduced pyrazole derivatives among the patent EP 94-116027 in barley, wheat and the selective difference on weeds and various processing formulation.Patent WO 03/024224A2 and WO 03/024227A2 apply for that also some contain the Herbicidal combinations patent of pyrrole grass ether.
Singenta Participation AG has introduced some and has contained the Weeding synergetic composition of pyribenzoxim in Chinese patent CN 100433977C, absorption, contact and weed killer herbicide comprise metamifop, trifloxysulfuron, bentazone, dichloro quinolinic acid, pyrrole grass ether, triasulfuron etc. in these.
Summary of the invention:
The present invention proposes in the pyrazole derivatives compound pyrrole grass ether (1) and or absorptions and/or contact herbicide nicosulfuron (Nicosulfuron), mesotrione (Mesotrione) Herbicidal combinations in some, can enlarge and carelessly extremely compose and most of weeds are all had significant synergistic effect.The chemical name of pyrrole grass ether is 2-chloro-5-(4-chloro-5-difluoro-methoxy-1-methylpyrazole-3-yl)-4-fluorobenzene fluoroacetic acid ethyl ester.
Be applicable to the interior absorption of composition of the present invention, the contact herbicide example is as follows:
A. nicosulfuron (Nicosulfuron), B. mesotrione (Mesotrione).
The IUPAC common name of the weed killer herbicide that provides in the above is as follows:
A
2-(4.6-dimethoxypyridin-2-base carbamyl aminosulfonyl)-N, the N-dimethyl nicotinamide
B
2-(4-mesyl 2-nitro-benzoyl) cyclohexane-1, the 3-diketone
Composition of the present invention can be two combinations, also can be the composition that three kinds of aforesaid compounds form.
The mechanism of action difference of the various compositions of composition of the present invention, synergy mutually between them, the pesticide resistance of weeds descends, and the herbicidal effect of composition is apparently higher than the herbicidal effect of each component list time spent, and herbicidal spectrum is wider.
Composition of the present invention can be used for various crop and prevent and treat multiple weeds, mainly standing grain such as grass family, Rubiaceae, composite family, Convolvulaceae basis, broad leaved weed is had the good restraining effect.Be used to prevent and kill off annual or perennial weed.
The ratio of pyrrole grass ether and interior absorption and/or contact herbicide is 1 based on the parts by weight of active constituent in the present composition: 500-500: 1, and the best is 1: 75-75: 1.
Composition of the present invention can also comprise auxiliary agent or filler, and the parts by weight of its shared composition are 0.5%-95%.
Composition of the present invention can be made into missible oil, wetting powder, suspending agent, aqua, pulvis, dust agent, paste, granula or sustained release agent.
Also to add surface reactive materials such as emulsifier, dispersant, wetting agent in the composition of the present invention, to increase stability, wetability, the permeability of composition.
The product that the present invention describes can be the finished product preparation form, and promptly material mixes in the product.Yet the composition of composition also can provide with preparation separately, directly mixes in jar before use.
Composition of the present invention also can contain other active constituent, and for example other has the compound of sterilization, desinsection or herbicidal performance, also can mix with nematocide, protective agent, growth regulator, nutrient for plants or soil conditioner.
Composition can use by common method, as pouring into a mould, spray, spray or dusting.
