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).
The aphids do not usually cause much damage to overall tree health, but dieback is occasionally seen on very heavily infested branches. If infestations are heavy, twigs may die, but damage to the tree is usually minor. The aphids can be blasted off with a jet of water or can be controlled with any insecticides labeled for aphids.
Their saliva causes a phytotoxic reaction in the phloem tissue in the twig which becomes necrotic. With the sap failing to reach the tips of the twigs, they may wither. The excess fluid sucked by the aphids is secreted by the aphids as honeydew, on which sooty mould often develops, and which attracts ants. The ants sometimes carry aphid nymphs ...
