Abstract :

Soybean crop ( Glycine max L.) is a very important economic crop belongs to Leguminosae and considered one of the high potentially protein source and attacked by cotton leaf worm Spodoptera littoralis (Boisd) which considered the major pest thought-out the growing season. Therefore, this study aimed to evaluate the insecticidal activity of methomyl against the cotton leaf worm S. littoralis on soybean genotype, Giza 21, to study the stability of this tested insecticide after application under some of the environmental factors such as exposure to the direct sunlight, and different temperature degrees, and finally to evaluate the effect of some commercial processes on the safe removal of methomyl residues from soybean seeds. The results showed that methomyl was effective against cotton leaf worm. The environmental factors such as exposure to the direct sunlight, and different temperature degrees significantly reduced levels of the tested insecticide. The results showed that the food processing is an important process in minimizing methomyl in the final products lower than the maximum residue limits. The removal percentage values were significantly, whereas, cooking procedures were the highest effect than dry heating at (90-95 ºC) on removal of tested insecticide from soybean seeds.
