Abstract

Benomyl thiophanate methyl chlorothalonil and mancozeb were tested against Races 4 6 7 and 8 of Microcyclus ulei for inhibition of conidial germination leaf disc infection and field disease control. Races 6 and 8 were less sensitive to benomyl and thiophanate methyl than Races 4 and 1. Spraying benomyl (25 mg and 50 mg per litre) in the nursery gave satisfactory control of South A merican leaf blight on clones FX 2261 and FX 985 infected by Races 4 and 1 respectively but not FX 3864 and FX 2804 infected by Races 6 and 8 respectively.
