Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).
Aphids can also transmit viruses and allow sooty mold to take hold. When the population becomes too large, an aphid might grow wings and fly away to find a fresh host plant.

In a study on tomatoes, it was shown that the aphids preferred smooth to hairy leaves and that susceptible tomato plants had higher sucrose, lower quinic acid and higher alanine and tyrosine levels. [10] In lettuce, butterhead varieties are mostly moderately to highly resistant to the aphid whereas crisphead varieties are susceptible. [11]
