| 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. |
| toxicity | The acute oral LD50 of rats was mg/kg, and that of mice was 2444mg/kg. Rat acute percutaneous LD50>3g/kg no rabbit skin irritation, rabbit eyes irritation. It had no sensitization effect on guinea pig skin. Acute inhalation LC50(4 H)>4G/m3. Feeding Test No effect dose: Rats (2 years) 3.8mg/(kg · d), mice (2 years) 0.71mg/(kg · d), dogs (1 year) 3.3mg/(kg-d). The ADI for a human is 0.03mg/kg body weight. No carcinogenic, teratogenic, mutagenic effects. Bird acute oral LD50(8 days): Japanese quail 2424mg/kg, Peking duck> 3000mg/kg, wild duck> 1590mg/kg. Quail and wild duck LC50(8 days)>5620mg/kg. Fish poisoning LC50(96 hours): Rainbow Trout 1.7~4.3mg/L, carp 3.8~4.6mg/L, blue gill 2.1~2.8mg/L. Pentoxifyl azole is non-toxic to bees, LD50 (oral and topical)>5 μg/Bee. Earthworm LC50(14 days)>1000 mg/kg. Daphnia LC50(48 hours) 7~11mg/L. |
| preparation method | 1-H-1,2, 4-triazole is reacted with sodium hydride in dimethylformamide, 4-dichloro-β-propylphenethyl methyl sulfonate was refluxed in dimethylformamide for 24 hours to obtain valoxazole (dichloropentatriazole). |
| Use | for the prevention and treatment of powdery mildew, Pseudomonas sp, pathogenic bacteria of the class sporozoites and the class of the class of the class of the genus of the genus of the genus of the genus of the genus of the genus of the fungus, The pathogenic bacteria of the class of the genus of the genus of the genus of the Black Star and other diseases, and the pathogenic bacteria of the class of the genus of the fungus and the genus of the genus of the genus of the genus. Especially on the pumpkin, grape, fruit, ornamental plants and vegetables of the above pathogenic bacteria, the effect is remarkable. |
