Abstract

The invention relates to paraquat-containing water dispersible granules for a pesticide herbicide and a preparation method thereof. The invention aims to solve the problem of animal poisoning of the existing paraquat water dispersible granules in the processes of production, storage and use. The technical scheme of the invention is as follows: paraquat water dispersible granules comprise the following components in percentage by weight: 5 to 95 percent of paraquat; 0.1 to 2 percent of wetting agent; 3% -8% of dispersant; 1% -35% of disintegrating agent; 0.1 to 4 percent of stabilizer; 0.1 to 4 percent of adhesive and 100 percent of filler. The paraquat water dispersible granule processed by the formula has the characteristics of good weeding effect, quick disintegration, good dispersibility, small environmental pollution, safety for users, simple package, convenient storage and transportation and the like.

Description

A kind of paraquat water dispersible granules and preparation method thereof that contains
Technical field
The present invention relates to a kind of paraquat water dispersible granules and preparation method thereof that contains, specifically, what the present invention relates to that a kind of pesticide herbicide uses contains paraquat water dispersible granules and preparation method thereof.
Background technology
Paraquat, chemical name are 1-1-dimethyl-4-4-bipyridine cation salt, are a kind of quick steriland herbicides, have action of contace poison and certain systemic action.Can make it withered rapidly by the green plant tissue absorption.To the not effect of non-chlorenchyma.In soil, combine and purifying with soil rapidly, invalid to plant root and perennial subterranean stem and perennial root.Be the quick-acting contact killing types natural disposition quaternary ammonium salts weed killer herbicide that goes out.Active ingredient is extremely strong to chloroplast tunic destructive power; Make the synthetic termination very soon of photosynthesis and chlorophyll; Blade behind the medicine and promptly to be begun the variable color of being injured in 2-3 hour; Gramoxone all has very strong destruction to unifacial leaf and dicotyledon chlorenchyma, is one of product of consumption maximum in the present weed killer herbicide kind.But paraquat has only the aqua kind in the market, and the user eats by mistake easily and poisons, and is very big to people's toxicity; And there is not specific drug; The oral ingestion lethality can reach more than 90%, in order to solve the harm of aqua to human body, paraquat is made the poisoning problem that water dispersible granules has solved the people.
Summary of the invention
The present invention aims to provide a kind of paraquat water dispersible granules and preparation method thereof that contains, to solve the poisoning problem of paraquat.With this paraquat water dispersible granules graininess that contains provided by the invention, disintegration is fast, good dispersion, little, the easy to use, safe coefficient of environmental pollution are high, little to human harm.
Another object of the present invention provides a kind of preparation method of above-mentioned paraquat water dispersible granules.
