An experiment was conducted in Laboratory of the Department of Plant Pathology, SHUATS, Prayagraj, and U.P. during 2018-19 to observe the effect of Beauveria bassiana (white muscardine fungus) with botanicals on root knot nematode (Meloidogyne graminicola) population in rice seedlings. In vitro compatibility of Beauveria bassiana was carried out with ten selected botanical extracts. The leaf extracts of Neem, Ashoka, Chrysanthemum, Marigold, Guava, Chilli, Castor, Hibiscus, Curry leaves and Lantana camara extracts were taken @ 10% for the compatibility of Beauveria bassiana by the food poison technique. After 4, 7 and 10 days of incubation the radial growth (mm) of Beauveria bassiana was recorded. Out of the selected 10 botanicals neem leaf extract shows significantly increased growth rate of Beauveria bassiana as 11.17, 14.50 and 18.00 mm/plate. A pot experiment was conducted in green house in combination of selected botanicals with Beauveria bassiana to see the effect on Root-knot nematode (Meloidogyne graminicola) population in rice seedlings. In the pots the selected botanicals were amended @ 10 ml each with Beauveria bassiana 10 ml (1×105 cfu) per pot infested with Meloidogyne graminicola @ 2 J/gm of soil.
