Description
Technical field
The present invention relates to a kind of pesticidal preparations and preparation method thereof, specifically relate to a kind of Stam F-34 water dispersible granules and preparation method thereof.
Background technology
Pesticide water dispersible granules be the former medicine of water-fast solid pesticide and wetting agent, dispersant, other function additive and carrier after sufficiently mixing, be ground into trickle powdery solid, then through operations such as kneading, granulation, dry and screenings, form in water rapidly disintegration be that primary granule is big or small and be dispersed into the formulations of pesticide of stable suspension.Water dispersible granules does not have solvent and dust, to operator's safety, do not have elegant, the weak points such as the conventional dosage forms solvent loads such as missible oil, pulvis and wetting powder are large, dust is many have been avoided, draw and utilized its advantage, development rapidly, is considered to one of the most promising formulation in 21st century pesticide processing field.
Stam F-34, English name propanil, chemical name N-(3', 4'-dichlorophenyl) propionamide, is white, needle-shaped crystals.Stam F-34 is transporting hardly in plant corpus, just in medicament contact site, works.Its mechanism of action is many-sided, not only destroys the photosynthesis of plant, but also suppresses respiration and oxidative phosphorylation, RNA and protein are synthetic etc., thereby the physiological function of sensitive plant is affected, and accelerate plant dehydration, make plant leaf blade dried-up gradually, finally dead.Stam F-34 as Monochoria vaginalis, Chinese celery, lady's-grass, green foxtail have excellent preventive effect, resolves into rapidly innocuous substance because Stam F-34 is hydrolyzed enzyme in paddy rice body, so fool proof to paddy rice to paddy field barnyard grass, grass family and broadleaf weed.
