Abstract
The white fly ( Bemisia argentifolli Bellows & Perring) causes serious damage to the common bean crop in Brazil. The indirect damage through the transmission of bean gold mosaic virus can cause losses of up to 100%. One measure recently developed to control this pest is insecticide seed dressing. In this study, the compatibility of the insecticide thiamethoxam with the fungicides used for dry beans seed dressing was tested. These treatments included the fungicides difenoconazole, fludioxonil and carboxin. The variables evaluated were germination, seed health and white fly control efficiency. Considering these variables it was observed that the insecticide was compatible with the fungicides studied. The treatments thiamethoxam+carboxin and thiamethoxam+fludioxonil were the most efficient in controlling seed-borne fungi as well as white fly on plants. KEY-WORDS: White fly; Bemisia argentifolli ; seed fungi; chemical control.
