bactericide | valdopazole is the most active triazene fungicide and a sterol demethylation inhibitor. Colorless crystals, melting point 57.6~60.3 ℃,20 ℃ when the vapor pressure is 0.37mPa, density 1.30 (20 ℃). Solubility (25 ° C): 73mg/L in water, 730g/L in ethanol, 770g/L in propanol, 610g/L in toluene, 22g/L in hexane, octanol in 400g/L. PKA 1.51. Stable to hydrolysis, stable below 350 °c. Through the crop root, stem, leaf and other active tissue absorption, and can quickly in the plant body with the body fluid conduction. The results of indoor activity test and field efficacy test showed that the effect of grape white rot, leaf spot, scab, anthracnose, powdery mildew also had good control effect. mode of action: endoscopically bactericidal, with therapeutic, protective and eradication effects. mechanism of action: inhibition of sterol demethylation, acting during germination and invasion of fungal spores. control object: pathogenic bacteria of the genus melanocephala and other pathogenic sporophytes, Basidiomycetes and semidioptera. Especially on the pumpkin, grape, kernel fruit, ornamental plants and vegetables of the above pathogenic bacteria. use method: 10~50g AI/hm2 dose spray, but use time as far as possible in the morning, in order to avoid irreversible damage to crops, increase disease. analysis method of valbuconazole: GLC for Product Analysis and GLC for Residue determination. |
