Tobacco caterpillar, Spodoptera litura (Fab.) is the key pest of tobacco in India. Studies were conducted to evaluate the efficacy of an insect growth regulator (IGR) chlorfluazuron (Atabron 5.4 EC) @ 0.0075%, 0.015% & 0.03% against the pest in a replicated experiment along with novaluron 10 EC @ 0.01%, lufenuron 5 EC @ 0.006% and emamectin benzoate 5 SG @ 0.0025% for two seasons in flue cured Virginia (FCV) tobacco (Nicotiana tabacum) cv. Siri at ICAR-Central Tobacco Research Institute farm, Rajahmundry, India. Results showed that emamectin benzoate 5 SG @ 0.0025%, was most effective in protecting tobacco from S.litura damage as shown by no damage at all in terms of number of leaves damaged, leaf area damaged and the damaged plants/plot. The next best treatment was chlorfluazuron (Atabron 5.4 EC) @ 0.03% as shown by number of leaves damaged (1.09 - 1.12%), leaf area damaged (2.71-4.18 %) and per cent plants damaged/plot (3.50 - 7.01%). Emamectin benzoate 5 SG @ 0.0025% treated plots recorded highest cured leaf (2485 kg/ha) as well as bright leaf yield (1163 kg/ha) and better grade index (1603) followed by chlorfluazuron @ 0.03% treated plots (2440, 1130 and 1555 kg /ha), respectively. Chlorfluazuron 5.4% EC @ 0.03% may be used to manage S.litura damage in rotation with emamectin benzoate Not Available |
