Abstract

Prochloraz Insensitivity in Isolates of the Cereal Eyespot Fungus, Pseudocercosporella herpotrichoides, in New Zealand A.C. King and A.L.J. Cole Department of Plant and Microbial Sciences, University of Canterbury, Christchurch, New Zealand; and F.R. Sanderson Department of Scientific and Industrial Research, Lincoln, New Zealand. The eyespot disease of cereals, caused by vey, two were also insensitive to benomyl at Pseudocercosporella herpotrichoides (Fron) 200 fJ.g/ml. Deighton, is a problem in New Zealand, chiefly on Recently, Scott and Hollins (1985) also spring-sown wheat and barley in Southland. reported that a few U.K. isolates of P. her­ Infection is promoted by frequent cereal cropping potrichoides showed some growth on media con­ and high rainfall. Host symptoms include ellipsoid taining prochloraz. The degree of insensitivity was lesions on the base of the culrns, shrivelled grain, not, however, a consistent feature of the U.K. and in extreme infections, stem loding. Control is isolates (Scott, pers. comm.). by cultural methods, especially crop rotation, to reduce the fungal mycelium which persists in the crop debris and the application of fungicides.
