| Abstract | ||
| Cotton (Gossypium barbadense L) crop have an important role in the national income of Egypt. Field experiments were achieved during 2023 at El- Gharbia Governorate, Egypt under field condition to evaluate the initial and residual effect of certain insecticides, which applied singly and mixed with Mineral oil or plant extract against Thrips tabaci during Seedling stages. Results showed that all tested compounds used separately induced the highest residual reduction against thrips. In the case when insecticides are applied alone, the mean of reduction in insect population varies between 44.31 to 80.37, while the initial effect of all tested compounds causes a moderate reduction giving from 45.49 to 69.15 against cotton Thrips. Also, the results obtained indicated that mineral oil and plant extract, when mixed with all tested compounds, caused a high level of reduction in insect population as initial and residual effect. mineral oil + Thiamethoxam caused the highest initial and residual reduction giving 88.76 and 89.09 respectively, while plant extract + Thiamethoxam caused the highest initial and residual reduction giving 84.41 and 82.42 respectively to cotton thrips. (control). Generally, we can said that all mixtures had potentiation effect which resulted in reducing thrips population (T. tabaci.) during seedling stage | ||
