Abstract

The invention relates to a sterilization composite with effective components consisting of difenoconazole and propineb, comprising the following components in percentage by weight: 5-11 percent of the difenoconazole, 50-70 percent of the propineb, 4-10 percent of dispersant, 2-5 percent of wetting agent, 5-10 percent of disintegrant, 2-6 percent of hard water resistant agent and the balance of filler, and the total percentage of all the components reaches 100 percent. The sterilization composition has the advantages of high efficiency, low toxicity, long efficacy duration, high product utilization rate, cost reduction and simple use, efficiently relieves the drug resistance and adopts extrusion granulation or boiling granulation as a granulation mode.

Description

Technical field [0001] The invention belongs to the technical field of pesticide compounding, and specifically relates to a water-dispersible granule germicidal composition compounded with difenoconazole and propsenzine. Background technique [0002] Difenoconazole is a triazole bactericide. It is a sterol demethylation inhibitor with good systemic properties. The product has the advantages of high efficiency, low toxicity, broad bactericidal spectrum and long lasting effect. This product is a colorless solid with a melting point of 76°C, a boiling point of 220°C / 4Pa, and a vapor pressure of 120nPa (20°C). Solubility (20°C): 3.3 mg / L of water, easily soluble in organic solvents, K(ow) 20000 (by reversed phase TLC), stable at ≤300°C. At present, the main preparations of difenoconazole include 10% water dispersible granules, 25% emulsifiable concentrates, and 3% suspension seed coatings. Mainly against Ascomycetes, Basidiomycetes and including Alternaria, Ascodia, Cercospora, Col...
