Have you been having a problem with Pythium root rot at your facility? Do you think that you may have resistant isolates? If so, you can contact the Plant Disease and Insect Clinic (link below) for more information about sample submission procedures. I am going to be actively sampling North Carolina greenhouses for Pythium isolates. If you would like us to sample your greenhouse or test your plants for mefenoxam resistance we might be able to add your facility to our list. Please contact the clinic for more information.
