Abstract:
A field experiment was conducted to study the efficacy of botanicals against pomegranate mealybugs, Ferrisia virgata Cockerell during Ambe and Hasta bahar 2021 at farmer field, Managuli, Vijayapur, UAS, Dharwad, Karnataka. The efficacy of botanical insecticides viz., Biodigester solution, Vermiwash, FORS (Fish Oil Rosin Soap), Pongamia leaf extract, Prosopis juliflora leaf extract, Lecanicillium lecanii, Neem based insecticide and Thiamethoxam 25 WG revealed that all these were significantly superior over control. Among different treatments the Thiamethoxam 25 WG showed most effective treatment against mealybugs with higher percent reduction of 80.75 (%) followed by followed by neem based insecticide (43.43%), L. lecanii (41.31%) and FORS (40.14%). Pongamia leaf extract and P. juliflora leaf extract treated plants were recorded as least effective treatment with 27.70 and 26.76 percent reduction of mealybugs per shoot over untreated control.
