Western flower thrips. Lannate SP has been registered for use on nectarines and peaches in Pennsylvania (24c) to control thrips. The label specifies 0.5 to 1 pound per acre. No more than three applications of Lannate can be made within a season.
Preharvest intervals are 1 day for nectarines and 4 days for peaches. Reentry into treated areas is prohibited for 3 days unless you wear personal protective clothing and equipment as specified on the Lannate L product label for early reentry.
Growers wishing to use Lannate 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 the thrips hide underneath leaves covering the fruit or around the stem end.
SpinTor is also registered for western flower thrips control. The preharvest interval is 1 day on nectarines and 14 days on peaches.
Sprays before harvest. Refer to Table 4-16 when selecting sprays during the last month before harvest.
VaporGard. VaporGard is an antitranspirant that may improve color and size; apply at a rate of 1 gallon of product in a minimum of 200 gallons of water per acre 2 weeks before anticipated harvest. Application may hasten maturity by approximately 3 days. Caution: Do not apply in a spray tank mixture of any insecticide or fungicide.
