Abstract
Insecticides are important for pest control on variety of crops. In recent
years the use of insecticides have increased particularly in greenhouses in
Benghazi area to protect vegetable crops, improve their quality and to increase
crop production. In this study, dimethoate was used to test their phytotoxicity
to cauliflower, cucumber, eggplant, okra, squash, turnip, tomoto and onion.The
results showed that germination and root extension in all tested species were
inhibited by dimethoate treatment. The results also showed that root elongation
in all tested species except cucumber was sensitive to dimethoate.
