Weekly Review for April 16, 2019
This informal report by the Division of Entomology and Plant Pathology is designed to update the Nursery and Greenhouse industry of insect and disease pests the Division has been encountering on a week to week basis and as a way to give a “heads up” of things to be on the lookout for. Comments and questions about this report are welcome and can be sent to your respective Inspector.
Welcome to the 2019 season of the Entomology Weekly Review. To start off the season, I have a few announcements.
If you haven’t checked out the webinars at EAB University in a while, please do. The spring season wraps up today with Emerald Ash Borer: Perspective from a Recently Infested State at 11 a.m. ET. If you missed them, don’t worry. All the talks are archived at the link above.
The Purdue Landscape Report is a great compliment to reading our Entomology Weekly Review. The folks at Purdue often dive into the same topics in more depth than we can with this report. You can subscribe and read back issues on their page.
In a bit of news from last fall, congratulations to Ken Cote, the 2018 winner of the Robert McAdams Award. Given by the Horticultural Inspection Society Central Chapter, the McAdams Award is awarded to an outstanding inspector for their contributions to the plant industry and their support of fellow inspectors in the 12 Midwest states who make up the chapter. Ken is only the second Indiana inspector to receive this award since it was created in 2001.
We had snow Sunday night. With these back and forth temperatures we’ve been having, it should be no surprise that I have been seeing a fair amount of frost/freeze damage on early plant material moving into retail stores. Package roses, Japanese maples, patio peaches and nectarines seem to have taken the heaviest hit. I’ve also seen frost damage on boxwoods. A lot of the stores in my area have gotten better about either getting the stock in early enough so it is still dormant or delaying long enough to avoid most of the cold. However, they still get hit once in a while.

Spring is here and nursery inspection season is well underway. I have helped out on a few greenhouse inspections in other inspectors’ territories and wanted to share some photos. I haven’t seen too many pest or disease issues yet this year, except a few aphids and some scattered Botrytis blight on various annuals (see last two photos).
