Penconazole Molecular Formula
Synonyms: 1-[2-(2,4-dichlorophenyl)-n-pentyl]-1h-1,2,4-triazole; propan-2-one O-(2-hydroxyethyl)oxime
It is a methyl group of inhibitors of cholesterol.
It can be absorbed by the active tissues of roots, stems and leaves of crops, and can quickly be conducted in the plants with the body fluid. According to the result of the activity determination of indoor and field efficacy trials, it on the effects of white rot of grape, leaf spot, scab, anthracnose and powdery mildew of also very good control effect.
Function: internal absorption sterilization, with treatment, protection, eradication.
Mechanism of action: inhibition of the formation of the effects of the germination and invasion of the fungus.
Control object: Erysiphaceae fungi spore Venturia and other pathogenic bacteria, pathogenic basidiomycetes and Deuteromycetes. Especially the pumpkin, grape, pome, ornamental plants and vegetables on the pathogen.
Using method: 10 ~ 50gai/hm2 dose spray, but the use of time as early as possible in the morning, so as to avoid damage to crops, increase the disease.
Amyl bacteria of Paclobutrazol rat acute oral LD502125mg/kg, acute percutaneous LD50>3000mg/kg acute inhalation LC50 (4h) >4000mg/m³ its on rabbit eyes and skin without irritation; skin of guinea pig sensitization; male rats 3 months feeding subchronic toxicity test maximum non effect dose is 300ppm; rat 2 years fed a chronic toxicity test maximum dose for 3.8mg/kg D.; no of experimental animal teratogen, induced mutagenesis and carcinogenesis. E% EC myclobutanil in rats acute oral, acute percutaneous LD50 were >2000mg/kg acute inhalation LC50 (4h) >4000mg/m³; non irritating to the eyes and skin of the rabbits, guinea pig skin sensitization. Penconazole and 10% TC EC showed low toxicity fungicide.
Environmental safety assessment:
Half-life of DT50133-343d in dry soil, and the half life of natural light was DT504d. On rainbow trout LC50 (96h) 1.7-4.3mg/L, carp LC50 (96h) 3.8-4.6mg/L, bluegill sunfish LC50 (96h) 2.1-2.8mg/L, Japanese quail LD50 (8D) 2424mg/kg, mallard LD50 (8D) >1590mg/kg. The bees basic no poison; earthworm LD50 (14d) >1000mg/kg; when spraying should avoid the honey bee season, never allow the pharmaceutical pollution water, ponds and silkworm and other.
Dosage: effective concentration 20 40mg / kg (dilution of penconazole% EC 25-50 times liquid), the onset of the start spraying, spraying methods for page spray. Safety interval for 30 days before harvest, on a quarterly basis up to times of medication for 3 times, recommended dosage is safe to crops, no phytotoxicity.
