Art,
Once the fruit is infested, cold storage for 3 days at 33F will kill the
majority of larva in the fruit, retaining the integrity of fruit at the
time of harvest from further injury.
- If the fruit are clean (uninfested) at the time of application AND
the material has a high degree of efficacy in reducing SWD egg laying, the
fruit will remain clean.
- If the fruit has been newly infested with one or more eggs you
may get some efficacy from the application to reduce larval activity,
with protection from further infestation in the field depending on
insecticide efficacy. Its likely they will remain infested with larval
activity increasing in storage unless cold treated.
- Sound stone fruit are much less likely to be infested. We have only
reared a singly fly from sound peach. We have seen oviposition on plum with
no fly emergence. Blueberry have shown to be much less attractive to SWD
then raspberry and blackberry. A 7 day schedule for blueberry using the
best materials has been shown to be effective at managing the pest
on many farms with consistent pest management programming. In the Hudson
Valley a 3d program is required in raspberry and blackberry
for commercial quality fruit.

If you apply a 3 day PHI spray for SWD will it continue to protect the
fruit in the packing room or retail stand? I'm thinking of peaches or
plums and blueberries.
