Abstract:

A field experiment was conducted to know the efficacy of bio control agents, plant extracts and fungicides against rice blast caused by Pyricularia grisea (Sacc.). Among the bio control agents and plant extracts Pseudomonas fluorescens (29.5%) and O. sanctum (33.1%) recorded less leaf blast incidence and higher grain yields of 2173 kg ha-1 and 2082 kg ha-1 compared with untreated plot 1552 kg ha-1. Out of seven fungicides were tested, spraying with tricyclazole resulted lowest leaf blast severity with 18.0% PDS followed by isoprothiolane (20.3% PDS) but the grain yields were higher in isoprothiolane treated plots 4061 kg ha-1 followed by tricyclazole treated plots 3837 kg ha-1 compared with untreated plots.
