Per the product label on Acephate 97UP Insecticide the ground application rate for aphids is 0.5 lb per acre. Apply at 3 day spray intervals to maintain control. Spray individual juvenile or non-bearing trees for coverage with total application not to exceed the specified rate in lbs. per acre. Length of residual activity will depend upon spray coverage and the amount of moisture following application.
