1 Aphids are best controlled with the silver-tip or 1/4-1/2" green spray; otherwise they will be within curled leaves and protected from insecticides. "Green aphids" are a complex of two species, spirea aphid (SA) and apple aphid (AA). SA has recently been found to predominate over AA in our area; they are indistinguishable in the field. SA and AA are equivalent in damage potential. AA is more susceptible to Guthion and Asana than SA.

Do not apply oil
when the temperature is higher than 85F or lower than 35F. Use only oil
having specifications that meet the standards for a superior oil.
Always
test such oil for physical compatibility before using it. See page 24
for
details. Dilute applications of oil are more effective.
