Comments and questions about this report are welcome and can be sent to your respective Inspector.
Off to a slow start on nursery inspections. Hollyhock rust was just starting out. Apple scab has the potential to problematic this year. Interestingly, I haven’t come across any fireblight to this point.

I was on vacation last week, so, I don’t have much to report, other than that on dealer inspections today I have been seeing a lot of drought-stressed plants. Most of these are out on pallets in parking lots at box store dealers and they are just not keeping up with the watering in this heat. The funny thing to me is that after the stores severely injure or kill the plants by not watering, they put them on the clearance rack.
It’s been a busy few weeks working on the Sudden Oak Death issue, but while removing infected rhododendrons from sale, I also noticed Sarah Bernhardt Peonies with a suspected virus. Purdue Plant and Pest Diagnostic Lab has confirmed Peony ringspot virus and Tobacco Rattle Virus on submitted samples.
