Abstract

Three insecticides, viz. Sulfoxaflor 24% SC at following three doses (100, 200 and 300 ml/ha), Protues 11% OD and Mospilan 20% SP at their field recommended doses were evaluated for their efficacy against whitefly ( Bemisia tabaci Genn) on cucumber at the farmer field in Kamesh Tapa village/Kwer/ Nineveh Governorate during autumn season of 2010.Sulfoxaflor @ 200 and 300 ml/ha and Proteus at its field recommended dose caused significant mortality of whitefly up to three days after first application. However, the most effective treatment for whitefly up to seven days after second application was Sulfoxaflor at 300 ml/ha while Sulfoxaflor at 100 ml/ha remained least effective while the others showed less than 73% mortality throughout the experiment.
