| Abstract |
Field experiments were conduced during 2004 and 2005 cotton growing seasons at Sakha Agricultural Research Station Farm to evaluate the effect of Gaucho and Cruiser as seed treatments at recommended and half rate as well as their mixtures with the fungicide; Rizolex-T against the thrips, Thrips tabaci (Lind.) and the cotton aphid, Aphis gossypii (Glov.) at early cotton season.
The obtained results revealed that Gaucho and Cruiser at recommended rate were effective against both thrips and aphids for 7 weeks after planting. The reduction percentage in thrips population was 78.4 and 72.1% , respectively in the first season and 69.5 and 63.4% respectively in the second one, while the effect on aphids was 77.8 and 60.1% reduction respectively in the first season and 71.8 and 58.7% reduction, respectively in the second one.. The effect of the two tested insecticides decreased with the decline of their rates and 1 or mixing with the fungicide; Rizolex-T. The data also, indicated that the tested insecticides had low toxic effect on the population density of associated predators. On the other hand, the fungicide; Rizolex-T alone had significantly the lowest effect on the population of the two insects as well as the predators .
Thus, it should not mixed the two insecticides ( Gaucho and Cruiser ) with the fungicide Rizolex-T as cotton seed treatments against the two sucking pests at early cotton season.
