Tapesia yallundae

Control wide range of pathogens like Tapesia yallundae, T. acuformis, Erysiphe spp., Pyrenophora teres, Rhynchosporium secalis, Botrytis spp., in cereals, grapes, pome fruit, stone fruit, strawberries, vegetables, field crops and ornamentals, barley Altemaria spp., Venturia spp. and... 

A unique feature of prothioconazole is that it shows equally good activity against both cereal eyespot species, OcuUmacula yallundae (= Tapesia yallundae = Pseudocercosporella herpotrichoides W-type) and O. acuformis = Tapesia acuformis = Pseudocercosporella herpotrichoides R-type) whereas all other triazoles used against eyespot control only O. yallundae effectively. Surprisingly, in cross resistance studies prothioconazole revealed a unique profile as far as no positive cross resistance to either triazole-resistant or to prochloraz-resistant isolates could be detected [94].
