ECOTOXICOLOGY
Effect on birds: Acute oral LD50 for mallard ducks >4500 mg/kg, bobwhite quail >5000 mg/kg, chickens 4600 mg/kg. Effect on fish: Acute LC50 (96 h) for Rainbow trout is 3.75 mg/l. Effects on aquatic invertebrates: Acute EC50 (48 h) for Daphnia magna is 0.59 mg/l. Effects on algae: Acute 72 hour EC50 for Raphidocelis subcapitata is 2.4 mg/l. Effects on bees: contact acute 48 hour LD50 is 100 μg/bee, oral acute 48 hour LD50 is 104 μg/bee. Effects on earthworms: Acute 14 day LC50 is 180 mg/kg.
ENVIRONMENTAL FATE
Animals: In rats, following oral administartion, rapidly metabolised, and eliminated in the urine (23%) and faces (75%) within 2 days. Soil: Slowly degraded by soil micro-oeganisms to various acidic metabolites. DT50 in silt loam soil 77 d. Koc 2728-7173 (3 soil types). Plant: Slowly metabolised to glycosides in plants.
Usage: Benalaxyl is developed by Isagro S.P.A. It is sysytemic fungicide, used to control grape downy mildew, tomato late blight and potato late blight, tobacco downy mildew.
Application: Systemic fungicide with protective, curative, and eradicant action. Absorbed by the roots, stems, and leaves, with translocation acropetally to all parts of the plant, including subsequent growth. Protective action is by inhibition of spore germination and of mycelial growth, whilst curative action is by inhibition of mycelial growth, and eradicant action is by inhibition of conidiophore formation. Control of Oomycetes, particularly fungi of the family Peronosporaceae, Phytophthora, Plasmopara, Pseudoperonospora, Sclerospora, Bremia, and Pythiumspp. Particular uses include control of late blights of potatoes and tomatoes; Downy mildews of hops, vines, lettuce, onions, soya beans, tobacco, and other crops; Diseases caused by Phytophthoraspp. In strawberries; Many diseases of flowers and ornamentals; And Pythiumspp. On turf. Often used in combination with other fungicides. Applied at 100-240 g/ha.
