Description
Technical field
The present invention relates to weed killer herbicide suspension agent of a kind of penoxsuam and ethoxysulfuron and preparation method thereof, belong to the technical field of agricultural chemicals.
Background technology
Pesticidal preparations is progressively to safe, environmental protection, water baseization development, and agricultural chemicals suspension agent is owing to having the following advantages 1. without dust harzard, to operator and Environmental security; 2. the water of take is dispersion medium, the inflammable and drug injury problem do not produced by organic solvent; 3. with wetting powder, compare, allow to select the former medicine of different-grain diameter, in order to make the biological effect of preparation and physical stability reach best; 4. liquid suspension spreads well in water, can directly make spray liquid and use; 5. than great, packaging volume is little.6. the dispersiveness of suspending agent and plate-out ability are all relatively good, and suspensibility is high, and the ability that sticks to the plant corpus surface is more intense, resistance of rainwater washing against, thereby drug effect is than wetting powder significantly and also more lasting.7. have that particle is little, active surface is large, penetration is strong,, drug effect high low without dust, cost while making up a prescription.And have the advantage of wetting powder and missible oil concurrently, and can be moistening by water, after thin up, suspension is good.Agricultural chemicals suspension agent be after the formulation of a kind of large usage quantity of the formulations of pesticide in using.
Ethoxysulfuron, chemical name: 1-(4,6-dimethoxypyridin-2-yl)-3-(2-phenoxy ethoxy sulfonyl) urea.Ethoxysulfuron is synthetic (ALS or the AHAS) inhibitor of branched chain amino acid.By the biosynthesis of blocking-up primary amino acid valine and isoleucine, thereby stop cell division and plant growth.Has good selectivity, be used to preventing and treating paddy field nutgrass flatsedge and annual broadleaf weed.Mainly 15% water-dispersible granules in the market.
Penoxsuam (penoxsulam) chemical name is 3-(2,2-difluoroethoxy)-N-(5,8-dimethoxy-[1,2,4] triazols [1,5-C] pyrimidine-2-base)-α, α, α-fluoroform phenyl-2-sulfonamide.It is to use weed killer herbicide after the triazolopyrimidine sulfonamide seedling, works by suppressing acetolactate synthestase (ALS).Penoxsuam is the rice field broad-spectrum herbicide, can effectively prevent and kill off barnyard grass (comprising the barnyard grass to Stam F-34, dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), moleplant seed and annual sedge weed, and effective to numerous broad leaved weeds, the weeds harm of full season of a drug energy basic controlling.Simultaneously, it also can prevent and kill off anti-bensulfuron-methyl weeds in rice field, and many broad-leaveds and sedge weed and barnyard grass etc. are had to residual activity, for by herbicide in weed killer herbicide, composing the widest kind in current rice field.
The penoxsuam preparation of current domestic registration is mainly oil-suspending agent, has no the weed killer herbicide suspension agent with ethoxysulfuron.
