Document Type : Original researches

Abstract

A Field study was conducted at EL-Beheira Governorate, Egypt to determine the insecticidal activities of pyridalyl, methomyl, emamectin benzoate, and lufenuron on tomato plants against the cotton leaf-worm (Spodotera Littoralis). Data obtained showed that a pyridalyl compound has the highest toxicity against the cotton leaf worm followed by methomyl then emamectin benzoate while the lufenuron has the lowest toxicity. The insecticide residue on the fruits of treated tomato fruits was extracted using QuEChERS method before analysis by HPLC-UV.
