Uses · 1 item
Prochloraz is a non-systemic imidazole fungicide, an ergosterol biosynthesis inhibitor with contact and translaminar, protectant and eradicant activity. It is used in agriculture and horticulture against various plant diseases, especially Ascomycetes and Fungi Imperfecti. It is used to control foliar diseases of cereals (Pseudocercosporella, Pyrenophora, Rhynchosporium and Septoria spp.), field crops (such as Alternaria, Botrytis, Pyrenopeziza and Sclerotinia in oilseed rape, Ascochyta and Botrytis in legumes, Pyricularia in rice), fruit (blossom blight) and vegetables (anthracnose). (L2082)
UsesProchloraz is a protectant and eradicant fungicide effective against a wide range of diseases affecting field crops, fruit, turf and vegetables. It is recommended for use on cereals against Pseudocercosporella, Pyrenophora, Rhyncosporium and Septoria spp. and on oilseed rape against Alternaria, Botrytis, Pyrenopeziza and Sclerotinia spp. When it is applied as a dip treatment it shows good activity against storage or transit diseases of citrus and tropical fruit. It is also used as a seed treatment to control several diseases of cereals.
UsesPlocloraz is used as a fungicide. Plocloraz showed efficacy against cereal powdery mildew.
