Abstract
Monilinia fructicola and M. laxa are the causal agents of brown rot blossom and twig blights and fruit rot of prunes (Prunus domestica) and apricots (P. armeniaca) in California. In contrast to 1974, M. fructicola was more commonly isolated than M. laxa from diseased prunes and apricots in 1982 and 1983. All isolates of M. laxa was sensitive to benomyl. Isolates of M. fructicola resistant to 1 .mu.g/ml benomyl were detected in prune orchards in 10 of 12 counties surveyed and in apricot orchards in all six counties surveyed. In addition, in three counties, M. fructicola isolates resistant to 4 .mu.g/ml benomyl were found in both prune and apricot orchards. Reasons for the shift in Monilinia spp. are discussed.This publication has 1 reference indexed in Scilit:
