Function

Fungicide with protective and eradicant action. A protectant and

eradicant fungicide effective against a wide range of diseases

affecting field crops, fruit, turf, and vegetables. An EC is

recommended for use in cereals (400-600 g a.i./ha) against

Pseudocercosporella, Pyrenophora, Rhynchosporium, and Septoria spp.,

with useful activity against Erysiphespp.; in oilseed rape (500 g/ha)

against Alternaria, Botrytis, Pyrenopeziza and Sclerotinia spp. Useful

activity is also shown against Ascochyta and Botrytis spp. in field

legumes; and Cercospora and Erysiphe spp. in beet. Good activity

against storage or transit diseases of citrus and tropical fruit when

applied as a dip treatment (0.5-0.7 g/l). A WP is recommended in mushrooms

against Verticillium fungicola and Mycogone perniciosa, and

in rice against Pyricularia. A seed treatment (0.2-0.5 g/kg) will control several

cereal diseases caused by Cochliobolus, Fusarium, Pyrenophora and

Septoria spp., and, in flax, Alternaria.
