In: Mansoura University Journal of Agricultural Sciences 2003.v.28(4)Summary: The insecticidal activity of Gaucho and Cruiser applied as seed treatments was evaluated against early season sucking pests (thrips, aphid, jassid, whitefly and mites on cotton under field conditions at the rate of 7 and 2 glk:g seeds respectively. Results revealed that Gaucho and cruiser were proved to be superior in the evaluation of thrips, they had relatively fast effects against thrips and residual effect lasted for seven weeks (pre-thinning), the percentage of reduction was (90.66 and 87.77%) for Gaucho and Cruiser, respectively. While the value of percentage of reduction was less in the other insect pests thaA thrips. Data also indicated that the tested insecticides have no significant decrease on the population density of associated predators. It was noticed that the two chemicals as seed treatment had improved the development of the cotton plant and there was not any phytotoxicity on cotton plants.
