New active agent combinations comprises: (A) 2-(alpha -(((alpha -methyl-3-trifluoromethyl-benzyl)-imino)-oxy) -tolyl)-glyoxylic acid methyl ester-O-methyl-oxime (trifluoxystrobin) (I); and (B) one or more of imidacloprid (II), thiacloprid (III), acetamiprid (IV), nitenpyram (V), thiamethoxam (VI), clothianidin (VII) and/or dinotefuran (VIII). - ACTIVITY : Fungicide; Insecticide; Bactericide; Virucide; Algicide; Acaricide; Nematocide; Antifouling. In tests against Aphis gossypii on cotton leaves, the degree of mortality after 6 days was 0% using 4 ppm trifluoxystrobin (I) alone, 25% using 0.16% imidacloprid (II) alone and 95% (compared with a predicted value of 25%) using a combination of 4 ppm (I) and 0.16 ppm (II). - MECHANISM OF ACTION : None given in the source material.
