Plum aphids: many aphid species that attack stone fruits return from summer hosts in the fall to lay overwintering eggs. Fall-applied aphicides may prevent egg-laying, and thus next year's spring population.
Shothole borer: Good sanitation (removing large wood pruning and wood piles from the orchard) is the best management tactic. Insecticides are only effective against adults. The second generation flight begins in late July or early August. Yellow sticky traps placed on orchard borders will detect activity of the adult beetles. Spraying the border trees (rows) with high water volumes will protect the remainder of the orchard in many situations where external sources are the primary problem.
Peach leaf curl, bacterial gummosis, coryneum blight: apply most materials before autumn rains or after October 1.
Omite 30WS: for use on nectarines only.
Basic Copper 53: rates vary according to manufacturer. Do not use copper materials before October 1, or before leaf drop.
