Woody Ornamental Pest Update
Posted: June 16, 2011
I was going to write about current active pests, but want to direct you again to the information posted June 13th about conifer damage reportedly caused by applications of the herbicide Imprelis this spring. I saw my first sample this week that look like the symptoms, though according to the information that was provided to me, there was not an application. I have also received a number of phone calls asking about the damage.
Emerald ash borer adults are active and feeding on foliage. They have not been documented in York County or counties to the east. However, keep an eye out for them so that any new infestations can be reported.
