1. A mixture comprising gamma-cyhalothrin and thiamethoxam, wherein the ratio of gamma-cyhalothrin to thiamethoxam is in the range of 1:2.5 to 1:100 (weight/weight), wherein when the mixture is applied by spraying at a rate of 0.25 ppm gamma-cyhalothrin and 1.25 ppm thiamethoxam onto Myzus persicae, the mixture is synergistically effective as determined by the Colby equation, wherein a mortality assessment is made 3 days after application with storage at 20° C.
