EFFECT OF SEED TREATMENT WITH METHYL JASMONATE ON INCIDENCE OF LEAF MINER (LIRIOMYZA TRIFOLII) IN TOMATO

The lab and field experiment were conducted at Kittur Rani Channamma College of Horticulture, Arabhavi to study the effect of seed treatment with methyl jasmonate (MeJA) on incidence of leaf miner (Liriomyza trifolii) in tomato (Solanum lycopericum) during the year 2023-24 with nine treatments and three replications.The results revealed that at 25 DAS treatment UHSB -POP recorded lowest per cent leaf damage (6.04%) and number of live mines (0.12 mines/leaf) it was followed by the treatment MeJA at 3 mM, 2.5 mM and 2 mM concentration and they were statistically on par with each other (10.89% and 0.33 mines/leaf, 11.21% and 0.34 mines/leaf, 11.44% and 0.35 mines/leaf, respectively).Additionally, at transplanted field, UHSB -POP recorded lowest per cent leaf damage (9.34%) and number of live mines (0.48 mines/leaf), it was followed by the treatment MeJA at 3 mM and it was statistically on par with 2.5 mM and 2 mM concentration (21.01%and 1.07 mines/leaf, 21.14% and 1.08 mines/leaf, 21.34% and 1.09 mines/leaf, respectively).
