2020 Clinic Sample Round Up

Posted by Blythe Howell | October 19, 2020

Harvest has wrapped up and with fall plantings on the horizon, here is what has been submitted to the clinic for the dryland cropping system.


Pea & Chickpeas:

  • Ascochyta Blight (Ascochyta species complex)
  • Root Rot Complex
  • Fusarium wilt/root rot
  • Bacterial Leaf Spot
  • Downy Mildew
  • Abiotic

Every year is different, but we often see certain diseases routinely such as root rots like Rhizoctonia, Pythium, and Fusarium. Other diseases we may only experience during certain years when conditions are conducive for pathogens growth or spread. The weather we experienced this year had an impact on the environmental conditions leading to more infrequent disease or conditions like Downy Mildew, Ascochyta Blight, Snow Mold, Bacterial Leaf Spot, and Physiological Leaf Spot.

Correct diagnosis is the critical first step in implementing a successful Integrated Pest Management system. The Plant Pest Diagnostic Clinic is here to help you with diagnosing plant problems!
