Abstract: Radish seeds (Raphanus sativus L.) were germinated at 25°C on moist filter paper for 5 days under continuous illumination (4000 lux). They were supplemented with 10-6-10-3 M concentration of cyanox or fenvalerate separately. Homogenous healthy plants from each treatment were taken for growth parameters. Another group of fresh cotyledons were taken for pigments estimation, some enzymatic activities and some biochemical analysis in the dry matter. In case of treated seeds, shows a significant drop in the percentage of germination especially by largest dose 10-3 M of cyanox. The length of the whole plant was significantly increased by both insecticides then dropped by high concentration of them. The fresh weight of treated plants decreased but more prominent by fenvalerate. There is no harmful effects on the pigments except the high dose 10-3 M, which decrease ch a to 65% of the control. The insecticides were not suppressive to soluble nitrogen components. The harmful effect was highly apparent on the insoluble nitrogen components and more prominent with the large doses of both insecticides. The treated plants, carbohydrates progressively increased by both insecticides than control. The alkaline phosphatase increased by both insecticides, the reverse was the case in the acid phosphatase.
