A pot experimental was conducted to the effect of foliar application of chemical insecticide (malathion) and biological insecticide (yeast emulsion) on growth vigor, pigments content, of bean plants and the quality of vielded seeds as well as its chemical composition. In the majority of cases, the two insecticides appeared to cause pronounced effect on growth parameters during growth of bean plants. Malathion application induced slight increase or marked decrease in pigments content and photosynthetic activity of 50 and 85 days old plant, respectively. On the other hand, yeast emulsion appeared to cause nonsignificant effect on the above-mentioned parameters, all over the growth period of bean plants. Foliar application of malathion caused significant decrease in growth promotery substances (i.e. IAA, GA3and cytokinin) with simultaneous increase in IAA-oxidase as well as abscisic acid content of bean plant. The application of yeast emulsion appeared without significant effect on growth regulators content of bean plants. Moreover, yield and yield attributes as well as the biochemical aspects of yielded seeds showed variable changes in response to malathion and yeast emulsion application.
