dc.description.abstractField trial was conducted from October 1998 to March 1999 in Maiduguri, Nigeria to evaluate the effectiveness o f neem seed oil (NSO) applied in water emulsified with soap in controlling tomato fruitworm, Helicoverpa (Heliothis) armigera in irrigated tomato. NSO significantly reduced the populations o f H. armigera larvae and the number and weight of damaged tomato fruits. NSO applied at the rate o f 20 ml/4 m2 provided better protection of fruits with less phytotoxicity than application at the rate o f 30 ml/4 nt. Yield of market able fruits increased with occasional exceptions, but damage and loss o f fruits decreased as the hot season (characterised by higher temperatures and longer day-lengths) approached.en_US
