Abstract: A field experiment was carried out to evaluate the bioefficacy of Tebuconazole 25.9 % EC against fruit rot and powdery mildew of chilli its persistence, phytotoxicity and effect on residual level and fruit quality. Experimental findings indicate that efficacy of the fungicidal products of Tebuconazole (Rainbow) 25.9% EC to increase crop yield and disease management of both fruit rot and powdery mildew was observed more or less equal to Azoxystrobin 23% SC and Tebuconazole 25.9% EC (Market sample). Among the different doses of Tebuconazole (Rainbow) 25.9% EC, plants treated @ 750 ml/ha was recorded highest yield and lowest fruit rot and powdery mildew disease incidence followed by dose of 625 ml/ha. Though, the effectiveness of lower dose of Tebuconazole (Rainbow) 25.9% EC @ 500 ml/ha was comparable to standard treatments. The combined bioefficacy and residue dynamics of Tebuconazole 25.9% EC @ 500 ml/ha to 750 ml/ha for the management of fruit rot and powdery mildew in chilli and facilitate its inclusion in good agricultural package of practices.
