The Illinois Cooperative Agricultural Pest Survey has been visually surveying and sampling black walnuts across the state of Illinois for the potential of Thousand Cankers Disease (TCD). They are encouraging anyone that has black walnut on their property or know of areas of black walnut stands to fill out a form and submit it for mapping purposes. In addition to surveying for symptomatic walnut trees, they are wanting to map as much black walnut as possible.
Please contact Kelly Estes (contact information below) for more information about Thousand Cankers Disease, the Illinois survey, and to obtain a form to submit walnut information on.
With the recent finds in Virginia and now Pennsylvania, the importance of this survey continues to grow.
