Abstract:
An experiment entitled “seasonal incidence and eco-friendly management of aphids” was conducted at the All India Co-ordinated Research Project on MAP and Betelvine, M.P.K.V, Rahuri, Dist. Ahmednagar (Maharashtra) during 2022-23. During the course of study, incidence of aphids (A. nerii) was initiated from 4^th week of October, 2022 (43^th SMW) and recorded up to 4^th week of January, 2023 (4^th SMW). The data revealed that average no of aphids per 10 cm twig ranged from 12.4 to 198.8 aphids per 10 cm twig during entire period. The incidence of aphids started in the month of October, 2022. The incidence increased up to the fourth week of November and reached its peak 198.8 aphids per 10 cm twig. Thereafter population declined gradually from 3^rd November (48^th SMW) and observed up to 20.5 aphids per 10 cm twig at 4^th week of January, 2023 (4^th SMW). As regard the eco-friendly management of aphids, among all treatment evaluated, treatment Lecanicillium lecanii @ 5 g/L showed to be the significantly superior treatment, which recorded 19.20 aphids per 10 cm twig found at par with Azadirachtin 10000 ppm @ 1 ml/L which recorded 33.27 aphid population per 10 cm.
