Abstract
The invention relates to a water dispersing agent of nicosulfuron, which comprises the constituents of nicosulfuron 3-85%, dispersing agent 5-40%, wetting agent 5-15%, and carrying agent 10-30%. The invention realizes good dispersity, suspending property and higher content of active ingredients.
Description
Technical field
The present invention relates to a kind of weed killer herbicide.
Background technology
Present nicosulfuron preparation mostly is suspending agent, wetting powder greatly, has excellent herbicidal, very fast degraded in environment, and its shortcoming is unstable, the processing formulation is less, consumes a large amount of organic solvents, and causes the pollution to environment.
Summary of the invention
At the problem of above-mentioned existence, the object of the present invention is to provide a kind of water dispersible granule of nicosulfuron, can improve the content and the stability of nicosulfuron in the preparation greatly, can also improve drug effect simultaneously, be convenient to store and transport and use.
For achieving the above object, a kind of water dispersible granule of nicosulfuron provided by the invention comprises following component: nicosulfuron 3-85%, dispersant 5-40%, wetting agent 5-15%, carrier 10-30%.
Further, described dispersant is optional: lignosulfonates, sulphate, sulfonate, phosphate, polyoxyethylene polyoxy third rare ether, alkylphenol-polyethenoxy polyphosphate one of them.
Further, described wetting agent is optional: aliphatic alcohol sulfate, alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, alkyl sulfate, alkylbenzenesulfonate, alkylnaphthalene sulfonate, carboxylate, alkylphenol-polyethenoxy base ether, Tea Saponin, bentonite, ammonium sulfate one of them.
Further, described carrier is optional: white kaolin, precipitated calcium carbonate or white carbon black.
The present invention has following advantage:
1, make water dispersible granules after, it is good to have a dispersed suspension, the active constituent content height, physical and chemical performance is stable, can widen the scope of application of medicament, prolong the lasting period, improve drug effect, and the saving organic solvent does not cause the pollution to environment, has the advantage of wetting powder and suspending agent concurrently;
2, owing to do not contain organic solution, not only alleviated destruction, and reduced production cost ecotope;
3, can greatly alleviate toxic action to user;
4, be convenient to the packing storing.
Embodiment
Embodiment 1
Take by weighing each component according to following ratio: nicosulfuron 65%, lignosulfonates 10%, ammonium sulfate 10%, precipitated calcium carbonate 15%, then these components are mixed, after pulverizing, airslide disintegrating mill gets female powder, female powder and binder liquid are stirred, the consumption of binder liquid is the 10-30% with respect to female grain weight amount, this binder liquid is made up of high molecular polymer, strong dispersion-ness surface activity agent and water, female powder with after above-mentioned binder liquid mixes, can be carried out extruder grain, and last drying, sieving promptly gets pesticide water dispersible granule of the present invention.
