Abstract

Studies were conducted to assess the physical, chemical and biological compatibility of new insecticides with fungicides against tobacco caterpillar, Spodoptera litura Fabricius. Emamectin benzoate 5 SG @ 0.0025 % in combination with copper oxy chloride 50 WP @ 0.2 % and azoxystrobin 23 SC @ 0.1 % recorded 100 and 96.43 % mortality within 48 hours after treatment. Spinosad 48 SC @ 0.012 % and its combination with test fungicides recorded less than 85 % mortality. Insect growth regulators, lufenuron 5.4 EC @ 0.006 % and novaluron 10 EC @ 0.01 % in combination with various fungicides also recorded reduced mortality. Hence, it is better to apply the insecticides and fungicides used in the study separately barring the combinations of emamectin benzoate 5 SG @ 0.0025 % with copper oxy chloride 50 WP @ 0.2 % and azoxystrobin 23 SC @ 0.1 % .
