Control of Septoria, Fusarium, Erysiphe and Pseudocercosporella in cereals; Sclerotinia, Alternaria
and Cylindrosporium in oilseed rape; Cercospora and Erysiphe in sugar beet; Uncinula and Botrytis in grapes; Cladosporium and Botrytis in tomatoes; Venturia and Podosphaera in pome fruit and Monilia
and Sclerotinia in stone fruit. Application rates vary from 120-600 g/ha, depending on crop. A seed treatment (0.6-0.8 g/kg) will control Tilletia, Ustilago, Fusarium and Septoria in cereals, and Rhizoctonia
in cotton. Also shows activity against storage diseases of fruit as a dip (0.3-0.5 g/l).
Stability Decomposes at m.p.; stable for at least 2 y below 50°C. Stable after 7 d at 20 000 lux. Slowly decomposed in alkaline solution (22 °C); DT50 >350 d (pH 5 and pH 7), 124 d (pH 9). Stable in acids, forming water-soluble salts. pKa 4.2, weak base
Mode of Action:
Systemic fungicide with protective and curative action. Absorbed through the roots and green tissues, with translocation acropetally. Acts by inhibiting development of the germ tubes, the formation of appressoria, and the growth of mycelia.
Oral Acute oral LD50 for rats 6400, dogs >2500 mg/kg.
Skin and eye Acute percutaneous LD50 for rabbits >10 000, rats >2000 mg/kg. Non-irritating to skin and eyes (rabbits). Not a skin sensitiser (guinea pigs).
Inhalation LC50 (4 h) for rats, rabbits, guinea pigs or cats, no effect with suspension (10 g/l water).
