Evolution du complexe parasitaire constitue par Rhizoctonia cerealis Van der Hoeven et Pseudocercosporella herpotrichoides (Fron) Deighton, champignons parasites de la base des tiges de cereales

Abstract : In France, among the pathogens causing foot rot of cereals, P. herpotrichoides has always been the most important. During recent years, however, R. cerealis has become increasingly important. In the presence of both pathogens, P. herpotrichoides was the predominant pathogen in untreated plots. After a carbendazim treatment, the frequency of eyespot symptoms decreased considerably, while that of sharp eyespot remained at the same level or increased. In vitro, mean ED 50 values for carbendazim were 1.9 μg/ml for R. cerealis and 0.06 μg/ml for P. herpotrichoides.
