Phony Peach

Based on observations at the Byron USDA station (pathology blocks) and Fort Valley State (Jeff Cook orchards), phony peach appears to be increasing in importance (see photos below; short, squat trees are phony peach trees).  I suspect this could be related to two really warm consecutive winters, increased vector numbers (sharpshooters), and less insecticide applications to non-productive orchards.  I also suspect that commercial producers are seeing the same. Unfortunately, destruction of symptomatic trees is still recommended, and we have virtually no other recommendations at this time.  We hope to obtain grant funding in the near future to further our knowledge of this disease and it’s management.
