Description

The Sulfosulfuron suspending agent of weeding

Technical field

The present invention relates to pesticide production technology field, the Sulfosulfuron suspending agent of particularly a kind of weeding.

Background technology

Sulfosulfuron is systemic herbicide, mainly through root system and the Foliage Absorption of plant.This product is branched-chain amino acid synthetic inhibitor, by hindering the biosynthesis of plant essential amino acid and isoleucine, makes cessation of cell division, plant stops growing then withered death.Though certain herbicidal effect can be reached existing for preventing and kill off annual and perennial grass family and part broad leaved weed the weed killer herbicide of wheat paddock, can not ensure the safety of wheat.

In addition, the missible oil formulation weed killer herbicide of current domestic use needs to use a large amount of organic solvents, large to environmental hazard; Wetting powder, in production and dust drift in using, causes the harm to environment and human body or even crops itself, does not also reach desirable herbicidal effect.

Summary of the invention

The object of the present invention is to provide and a kind ofly can replace the emulsifiable concentrate and wetting powder and the Sulfosulfuron suspending agent of the weeding of the novel environment friendly of good impurity removing effect that use at present.

In order to realize object of the present invention, the invention discloses a kind of Sulfosulfuron suspending agent, its each volume of material ratio is:

Sulfosulfuron: 25% ~ 45%; Defoamer: 0.5% ~ 1%;

Cosolvent: 1% ~ 2.5%; Thickener: 1% ~ 2%;

Wetting agent: 1% ~ 3%; Preservative: 0.5% ~ 1%;

Dispersant: 1.5% ~ 3.5%; Water complements to 100%.

Preferably, each volume of material ratio of weeding suspending agent used is:

Sulfosulfuron: 30% ~ 40%; Defoamer: 0.5% ~ 1%;

Cosolvent: 1% ~ 1.5%; Thickener: 1% ~ 2%;

Wetting agent: 1% ~ 1.5%; Preservative: 0.5% ~ 1%;

Dispersant: 1.5% ~ 2.5%; Water complements to 100%.

Wherein, selected weeding suspending agent active component is Sulfosulfuron, and its chemical name is 1-(4,6-SDM-2-base)-3-(2-ethylsulfonyl imidazoles [1,2-a] pyrimidin-3-yl) sulfonylureas.

In addition to the active ingredient (s, defoamer is one or more in organosilicon, dimethyl silicone polymer; Cosolvent is one or more in propane diols, glycerine; Thickener is one or more in urea, xanthans, sodium alginate; Wetting agent is one or more in alkylphenol formaldehyde APEO, fatty alcohol-polyoxyethylene ether, organic silicon modified by polyether oxygen alkane; Preservative is one or more in Sodium Benzoate, Kathon CG; Dispersant is one or more in calcium lignosulfonate, sodium methylene bis-naphthalene sulfonate.

Suspending agent of the present invention makees solvent with water, avoid emulsifiable concentrate a large amount of with an organic solvent to the harm that environment produces, and without dust drift, abrasive grains is little, good stability, Anti-freeze fluid, the safety that improve transport and store; Be applied to wheat paddock weeding after bud, can effectively prevent and kill off most of broad leaved weed and grassy weed, and without the transfer of Sulfosulfuron residue and delay, improve the safety of agricultural product, also can be used for uncultivated area weeding.
