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.

I am seeing more of the same this time of year. In many cases, like spider mite or tar spot, pests that have been around for a while this season are becoming more noticeable as the plants exhibit the damage.

I am seeing a few cases of heavy, local finds of things like bronze birch borer and bark beetles where the stock came into the nursery already infested. This highlights the importance of taking the time to look at things as they come off the truck and before new pests are introduced to the nursery.

Angela Rust (Nursery Inspector & Compliance Officer) - ARust@dnr.IN.gov

Over the past couple of weeks, here are some of the pests that I have found: Maple mites on Red Maple, Red Headed Flea Beetle and damage on Buttonbush, Japanese Maple Scale on Pink Flowering Dogwood, aphids on White Oak, Powdery Mildew on Flowering Dogwood, Japanese Beetle damage to Elm, Oaks, Sandcherry and Serviceberry, and Oystershell Scale on Winterberry.

Trip Report
Eric Biddinger, Eric Bitner, Vince Burkle, Jared Spokowsky and Angela Rust attended a two day training last week in the Cincinnati, Ohio area. The event was hosted by the Horticultural Inspection Society Central Chapter (HISCC), the Ohio Department of Agriculture, the USDA APHIS Asian Longhorned Beetle (ALB) Office in Bethel, Ohio, and the Center for Plant Health Science and Technology (CPHST) Lab. There were 17 HISCC members in attendance from Indiana, Kansas, Missouri, Michigan, Wisconsin and Ohio. Thank you to the National Plant Board and SANC Core Group for providing part of the funding for this educational event.

Day one was education and field training for Asian Longhorned Beetle detection. The training provided education on the biology of ALB, damage recognition, the status of ALB in Ohio, how survey and eradication is conducted in Ohio, and the current status of ALB research. One of the highlights was inspecting a recent ALB find and getting a firsthand look at damaged trees. The training was excellent and will assist inspectors on how to survey for ALB in their states.

The second day of our educational event was spent at an Ohio nursery where our HIS members worked together to do inspections of plant material and share pest information. These kind of events are invaluable because it serves as training for new inspectors plus attendees always get to see new pests that we don’t often get to see in our own states. It is also an opportunity to walk through the System Approach to Nursery Certification (SANC). SANC is a voluntary program to promote a harmonized risk-based approach to nursery certification.
