COLUMBIA, Mo. – Those attending the annual Mizzou Pest Management Field Day can bring plants for free testing and identification of disease and insects.

The field day is Thursday, July 6, at the University of Missouri’s Bradford Research Farm, 8 miles east of Columbia.

MU Plant Diagnostic Clinic representatives will accept samples for diagnosis and return them in 3-5 business days.

Samples should not be completely dead or dry, says Peng Tian, director of the clinic. He recommends bringing at least three plants to be submitted. Put plants in a zipped plastic bag with a wet paper towel. Remove soil from the roots and include all the roots.

Registration for the field day is $20, which covers lunch, refreshments and materials. To register, contact Bradley at 573-882-4039 or
