Fluopyram and fluazinam compounded granule and preparation process thereof

Abstract

The invention relates to a fluopyram and fluazinam compounded granule. The fluopyram and fluazinam compounded granule comprises a phase A, a phase B and a phase C, wherein the phase A comprises 1-10% of fluopyram and1-10% of fluazinam; the phase B comprises 60%-95% of a bio-based high polymer material chitosan-calcium carbonate particle carrier; and the phase C comprises 0.2-50% of functional bonding slurry. The fluopyram and fluazinam compounded granule is scientific and reasonable in design, and the adopted carrier is a bio-based high polymer material chitosan-calcium carbonate particle, is wide in source, simple, easy to obtain and good in biodegradability, and can also be used as a nutritional ingredient to provide certain nutrients for crops; the used slurry is sucrose-starch mixed liquor, so that the water solubility is better, and the drying speed is high; the coating is carried out for three times, the raw medicine is more uniformly coated and is easy to dry, the drying process is omitted, the energy consumption is reduced, the fast-acting property is better, the lasting period is long, and the problems of granule sticking, difficulty in drying and the like caused by a large amount of materials and slurry during the preparation of granules with higher content are avoided.

Description

technical field [0001] The invention belongs to the field of pesticide processing, and relates to a granule preparation technology, in particular to a granule compounded with fluopyram and fluazinam and a preparation process thereof. Background technique [0002] Fluopyram is an SDHI (succinate dehydrogenase inhibitor) bactericidal and nematicide developed by Bayer CropScience. It interferes with its respiration by inhibiting the activity of the target succinate dehydrogenase. When the nematodes were treated with fluopyram, the worms became stiff and needle-like, and the activity decreased sharply. Fluopyram selectively inhibits complex II of the respiratory chain in nematode mitochondria. Mitochondria are the energy factories of nematodes, and their inhibition leads to rapid depletion of energy (ATP) in nematode cells. It is the first nematicide acting on this target and represents a new class of nematicides with a new mechanism of action. It is also the first nematicide...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a kind of fluopyram and fluoride that effectively solves the problems of clay particles and difficulty in drying caused by the amount of material and slurry when preparing granules with high content. The granules compounded with pyridine and amine and its preparation process are coated three times. The original drug is more evenly coated and easy to dry. It saves the drying process, saves energy consumption, and has better quick-acting and long-lasting effects.
