abstract
An experiment was carried out on jamun orchard located at Research farm of AICRP on Arid Zone Fruits, Department of Horticulture, M.P.K.V., Rahuri during the period of February, 2019 to December, 2019 to study the seasonal incidence and management of pests infesting jamun (Syzygium cuminii L.). The peak level of infestation of leaf eating caterpillar was noticed during the month of November (47^th MW) and recorded 28.71% leaf damage. Whereas, the chafer beetles, leaf miner and fruit borers peak level of infestation was noticed during the month of June (25^th – 26^th MW) and recorded 19.18%, 1.87% and 67.70% damage respectively. Correlation studies indicated that, the leaf eating caterpillar and fruit borer were found positively correlated with minimum temperature, relative humidity I & II and rainfall. Whereas, the chafer beetles and leaf miner were found positively correlated with maximum temperature and minimum temperature. The pooled data on efficacy of various treatments revealed that, the treatment with NSE 5% was found the most effective treatment for the management of leaf feeders and fruit borer infestation which was found at par with the treatment of Azadiractin 10000 ppm @ 2 ml/ lit. of water and Neem oil @ 2 ml/ lit. of water and recorded least leaf eating caterpillar damage in the range of 7.19 to 8.36 per shoot per branch and fruit borer damage was recorded in the range of 6.37 to 9.17 % as against 42.67 % in untreated control. As regards the yield of jamun, the treatment with NSE 5%, Azadiractin 10000 ppm and Neem oil @ 2 ml/ lit. of water registered the higher fruit yield i.e., 30.54, 28.45 and 27.25 kg/tree respectively.
