Insecticides were evaluated for toxicity to Rosy Apple Aphids and Green Apple Aphids. There was 2 replicates of each treatment with each replicate containing 5 infested terminals to achieve a nested design. Treatments were applied on June 24 to 13 year old Sungold trees by using a back pack sprayer to saturate infested terminals. Live aphids were counted 72 hours after treatment.
