Abstract

The invention discloses a sulfosulfuron suspension for weed control. The sulfosulfuron suspension for weed control comprises sulfosulfuron used as an active ingredient, a co-solvent, a wetting agent, a thickening agent, a preservative, a de-foaming agent and water with the volume ratios as follows: sulfosulfuron is 25-45%, the de-foaming agent is 0.5-1%, the co-solvent is 1-2.5%, the thickening agent is 1-2%, the wetting agent is 1-3%, the preservative is 0.5-1%, a dispersing agent is 1.5-3.5%, and the total volume is supplemented to be 100% by water. The sulfosulfuron suspension has the advantages that, through using water as the solvent, the danger to the environment caused by using a large amount of organic solvents in an emulsifiable concentrate is avoided, dust drift is avoided, the ground particles are small, the stability is good, the product is anti-corrosion and anti-freezing, and therefore the safety in transportation and storage is improved; the suspension is applied to a wheat field for weed control after a budding period of the wheat, then most broad-leaf weeds and grassy weeds can be prevented and controlled effectively, and the shift and retention of sulfosulfuron residue are avoided, and consequently, the safety of agricultural products is improved.

Description

The Sulfosulfuron suspending agent of weeding

Technical field

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

Background technology

Sulfosulfuron is systemic herbicide, mainly by 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 cell stop division, plant stops growing then withered dead.Though existing, for preventing and kill off wheat paddock weed killer herbicide annual and perennial grass family and part broad leaved weed, can reach certain herbicidal effect, to the safety of wheat, can not guarantee.

In addition, the missible oil formulation weed killer herbicide of current domestic use need to be used a large amount of organic solvents, large to environmental hazard; Wetting powder is dust drift in producing and using, and 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 a kind of Sulfosulfuron suspending agent that can replace the weeding of the emulsifiable concentrate of current use and the novel environment friendly of wetting powder and good impurity removing effect.

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-yl)-3-(2-ethylsulfonyl imidazoles [1,2-a] pyrimidin-3-yl) sulfonylureas.

Except active component, 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 is made solvent with water, avoided a large amount of harm with an organic solvent environment being produced of emulsifiable concentrate, and without dust drift, abrasive grains is little, good stability, Anti-freeze fluid, the safety that has improved transportation and stored; After bud, be applied to wheat paddock weeding, can effectively prevent and kill off most of broad leaved weeds and grassy weed, and without transfer and the delay of Sulfosulfuron residue, the safety that has improved agricultural product, also can be used for uncultivated area weeding.
