Efficacy of entomopathogenic fungi against mango hoppers

Author(s): RD Tumbada, DS Pokhrkar and RV Datkhile
Abstract: Field experiment was conducted to evaluate efficacy of M. anisopliae (1 x 109 CFU/ml), M. anisopliae (1 x 107 CFU/ml), B. bassiana (1 x 109 CFU/ml), B. bassiana (1 x 107 CFU/ml), L. lecanii (1 x 109 CFU/ml), L. lecanii (1 x 107 CFU/ml), azadirachtin 10,000 ppm and thiamethoxam 25 WG against mango hoppers during 2014-15 and 2015-16 at the central campus of Mahatma Phule Krishi Vidyapeeth (MPKV), Rahuri (M.S.). Total four sprays were given with initiation of first spray during pre-flowering season (15 days before flowering) and remaining three sprays were given during flowering season at 15 days interval. The application of thiamethoxam 25 WG was found statistically superior over rest of the treatments in suppressing the hopper population (1.14 hoppers/panicle) and registered highest fruit setting (220.17/100 panicles) at marble stage and fruit yield (10.50 t/ha) at harvest with monetary returns of Rs. 3,15,000/- per ha. The next promising treatments were azadirachtin 10,000 ppm (2.85 hoppers/panicle) and M. anisopliae @ 1 x 109 CFU per ml (3.27 hoppers/panicle) which recorded fruit yield of 9.25 and 10.02 t per ha with monetary returns of Rs. 2,77,500/- and Rs. 3,00,600/- per ha, respectively. The L. lecanii (1 x 109 CFU/ml) registered fruit yield of 9.01 t per ha with monetary returns of Rs. 2,70,300/- per ha. However, the treatment with B. bassiana (1 x 107 CFU/ml) was found least effective against the hoppers. Among all the treatments, the highest ICBR (1:17.2) was recorded with M. anisopliae (1 x 109 CFU/ml).
