In response to the COVID-19 epidemic, the Plant Diagnostic Clinic will be providing diagnostic support to our clients primarily via email and phone. We will limit the number of physical samples that are received and processed in order to minimize the risk of COVID-19 to our staff and students.
Before sending a sample, please email us at firstname.lastname@example.org. You may also call us at (970) 491-6950 and leave a message. We are doing most of our work remotely, but we will check messages regularly and return your call as soon as possible.
We know that these changes are difficult but we will do our best to continue to help with your diagnostic needs in these challenging times.

Disease of the Month
Bacterial leaf streak (BLS) in corn
Caused by the pathogen Xanthomonas vasicola pv. vasculorum
First identified in Colorado in 2014
Symptoms include irregular necrotic lesions surrounded by a yellow halo
The bacteria often oozes from the lesions and is spread by rain and hail
This pathogen survives in corn residue so control of crop debris and rotation are important management strategies for BLS
