Fourth Cover to Preharvest
Diseases. Brown rot, scab.
Insects. Oriental fruit moth, mites, borer, scales. Apply pesticide at 14-day intervals.
Western flower thrips. Lannate SP has been registered (24c) for use on nectarines and peaches in Pennsylvania to control thrips. The label specifies 0.5 to 1 pound per acre. No more than three applications can be made within a season. The preharvest interval for nectarines is 1 day. Reentry into treated areas is prohibited or 3 days unless you wear personal protective clothing and equipment as specified on the Lannate L product label for early reentry. SpinTor 2SC is also labeled for thrips control on nectarines with a 1-day preharvest interval.
Growers wishing to use Lannate or SpinTor for thrips control should carefully check early ripening fruit for the presence of silvering, the damage caused by feeding thrips on the skin of the fruit. It is extremely important that you cover fruit thoroughly with spray, since thrips hide underneath leaves covering the fruit or around the stem end.
