Difenoconazole is a broad spectrum fungicide that controls a wide variety of fungi. It acts as a seed treatment, foliar spray and systemic fungicide. Difenoconazole is a broad spectrum fungicide that controls a wide variety of fungi - including members of the Aschomycetes, Basidomycetes and Deuteromycetes families. It acts as a seed treatment, foliar spray and systemic fungicide.
Systemic fungicide with a novel broad-range activity protecting the yield and crop quality by foliar application or seed treatment. Provides long-lasting preventive and curative activity against Ascomycetes, Basidiomycetes and Deuteromycetes, including Alternaria, Ascochyta, Cercospora, Cercosporidium, Colletotrichum, Guignardia, Mycosphaerella, Phoma, Ramularia, Rhizoctonia, Septoria, Erysiphe and Venturia spp., Erysiphaceae, Uredinales and several seed-borne pathogens. Used against disease complexes in grapes, pome fruit, stone fruit, potatoes, sugar beet, oilseed rape, bananas, cereals, rice, soya beans, ornamentals and various vegetable crops, at 30-125 g/ha. Used as a seed treatment against a range of pathogens in wheat and barley, at 3-24 g/100 kg seed. Phytotoxicity In wheat, early foliar applications at growth stages 29-42 might cause, in certain circumstances, chlorotic spotting of leaves, but this has no effect on yield.
