Two new mixtures of already recommended pesticides, imidacloprid and tebuconazole (Imidal 70 WS + Defender 2% WS and Gaucho 600 FS + Raxil 120 FS) were evaluated against flea beetles and pre- and post- emergence diseases in season 2007/08 at Gezira Research Station Farm and Crop Protection Research Center laboratories. The mixtures were evaluated in the two commercial cotton cvs, Barac (67) B and Barakat 90. The reductions in flea beetles damage and seed _ bed losses due to the two new mixtures were comparable to those of their counterpart; Gaucho 70 WS + Raxil 2 WS gave comparable control of disease and flea beetles as well as seed cotton yield to the counterpart. The seed cotton yield of both cotton cvs obtained by the new mixtures was either significantly higher or comparable to that of the counterpart
