GENERAL INFORMATION Click here for an explantaion of the general chemical status information
for fosetyl

Description: A fungicide for various horticultural crops used to control a range of plant pathogens. Usually used as the aluminium variant.

Example pests controlled: Phytophthora and Pythium root and crown rots, Pseudomonas apple blister spot, Alternaria

Example applications: Fruit including grapes, apples, pears raspberry, blackberry, strawberry; Ginseng; Lettuce; Onion; Broccoli; Tobacco; Turf; Ornamentals

Efficacy & activity: Fosetyl is an approved fungicide under EU regulations and is usually used as the aluminium salt. Most of its reported properties apply to the aluminium variant which has a high aqueous solubility and a low volatility. It is not usually persistent in soil systems but may, under certain conditions, persist in water. It has a low mammalian toxicity and is not associated with any serious medical conditions but may be an eye irritant. It has a low to moderate toxicity to most terrestrial and aqueous species.
