| Fungicide |
Cyproconazole is a kind of triazole agricultural fungicide with the mechanism of action being inhibition of sterol demethylation with prevention and treatment effect. Currently it has been widely used in pesticides, being effective in the treatment of powdery mildew, rust fungi, Rhizopus, Cercospora, Acipenseris and Scleroderma in cereal crops, coffee, sugar beet and fruit trees. It is effective in the treatment of following plant diseases such as the rust diseases of cereals and coffee, powdery mildew diseases of cereals, fruit trees and grape, leaf spot of peanuts and beet, apple scab and white rot disease cereal eye spot, leaf spot and reticulosis of peanuts.
Its persistence in the treatment of wheat rust disease is about 4 to 6 weeks and of powdery mildew is 3 to 4 weeks. The spraying method is as follows: spray, the dosage is 80g/ha for cereal crops, 20-50g/ha for coffee, 40-60g/ha for beets and 10 g/ha for fruit tree. For example, we can apply 40~100g/ha for prevention of cereals and coffee rust, cereal, fruit powdery mildew and so on. Cyproconazole can be mixed with other fungicides for better control of cereal eye disease, leaf spot and leaf net blotch disease.
Analytical method: The product was analyzed by GLC or HPLC. The residue was assayed by GLC.
Allowable residue: The residual amount of the parent compound in the cereal crop is 0.03 mg/kg. |
| Toxicity |
Male rats had acute oral LD50 of 1020 mg/kg, female rats of 1333 mg/kg; male mice of 200 mg/kg and female mice of 218 mg/kg. Rats, rabbits acute percutaneous LD50> 2g/kg; rats acute inhalation LC50 (4 hours)> 5.65mg/L • air. (1 year) and 1 mg/(kg • d) in rats (2 years). No irritation to rabbit skin and eyes, no mutagenic effect, no skin allergies to guinea pigs. Low toxicity to birds, quail acute oral LD50 of 150mg/kg; LC50 of duck in 8 days feeding test is 1197mg/kg, while the value for quail is 816mg/kg. Fish poisoning LC50 (96 hours): carp 18.9mg/L, rainbow trout 19mg/L, blue gills 21mg/L. Bees LD50> 0.1mg/bee (contact),> 1mg/kg (oral). Daphnia LC50 (48 hours) was 26 mg/L. |
| Chemical Properties |
Colorless, crystalline solid. Odorless. |
| Uses |
Cyproconazole is a fungicide treatment for wood preservative that prevents decay from fungi in above-ground applications. |
| Uses |
Cyproconazole is used as a systemic fungicide to control cereal and sugar beet foliar diseases: Septoria, rust, powdery mildew, Rhyncosporium, Cercospora and Ramularia. It is also used in fruit trees, vines, coffee, banana, turf, and vegetables to control Venturia, powdery mildew, rust, Mycosphaerela, Monilia, Mycena, Sclerotinia and Rhizoctonia. |
| Agricultural Uses |
Fungicide: Used to control fungus on cereals, coffee beans; anthracnose and other diseases on turfgrass; used against rust and leaf spot disease. |
| Potential Exposure |
Triazole fungicide used to control fun- gus on cereals, coffee beans; anthracnose and other diseases on turfgrass; used against rust and leaf spot disease. |
| Metabolic pathway |
Cyproconazole is a mixture of diastereiosomers and the preferential mammalian metabolism of one isomer has been observed. Pathways of metabolism in plants and mammals are quite similar. Metabolism primarily involves oxidation of the terminal methyl group to alcohols and carboxylic acids and/or hydroxylation at the 3-position. Loss of the alkyl cyclopropyl moiety or the triazolyl ring also occurs. |

| Incompatibilities |
The triazoles are sensitive to heat, fric- tion, and impact. Sensitivity varies with the type substitu- tion to the triazole ring. Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives . |
| Waste Disposal |
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Contact a licensed disposal facility about surplus and nonrecyclable solutions. Burn in a chemical incinerator equipped with an afterburner and scrubber. Extra care must be exercised as the material in an organic solvent is highly flammable. In accordance with 40CFR165, follow recom- mendations for the disposal of pesticides and pesticide con- tainers. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by con- tacting your regional EPA office. Incineration or permanga- nate oxidation. |
