ABSTRACT

Tomato (Lycopersicon escolentum L.) belonging to Solanaceae is the most widely and popular vegetable crop grown all over the world. Field experiment was carried out at National Tea and High Value Crops Research Institute (NTHRI) Shinkiari District Mansehra Pakistan in summer 2017.  Tomato seedlings were transplanted in the field in Randomized Complete Block Design (RCBD) with three replications. Five treatments were selected via Neem extract, Tobacco extract, Garlic extract, Steward 150 EC and Control. Neem extract was found best having lowest fruit borer (0.73), thrips (1.78) and white fly (1.92) population, tobacco extract was found effective against aphids (2.01) while steward effectively reduced cutworms population (2.71). The chemical poison steward was found fruitful having maximum average fruit weight (75.46), less fruit damage (11.64) and highest yield (21.85). The quality analysis indicates that minimum number of weight loss (11.16) was observed in tobacco. It was concluded from the abive findings that natural insecticides are effective, safe easy to handle and environment friendly. Natural insecticides should be used instead of synthetic chemical.

Key Words: Tomato, Solanaceae, Neem, Tobacco, Mansehra.
