A field trial was conducted for 4 years (1989-93) in different rice seasons in various areas endemic to rice hispa, Dicladispa armigera in Assam, India, to assess the efficacy of a mycopathogen, Beauveria bassiana for controlling the insect. Multi-locational field trials with B. bassiana (10 million spores/ml dilution), 1% neem-seed oil and a conventional insecticide (0.072% monocrotophos) revealed that the mycopesticide was superior to neem-seed oil but at a par with monocrotophos in controlling the rice hispa, leading to an increase in yield.
