Pythium warning

With a threat temperature of 70F (21C), Pythium has begun to hit in some warmer locations. Symptoms are similar to those caused by Rhizoctonia (brown patch) and Waitea (brown ring patch), so look for water-soaked foliage, which is associated with Pythium, but not with Rhizoctonia or Waitea.

Frequently, however, microscopic examination is necessary for a definitive identification. If you need assistance from a trained professional, we have provided a listing of turf diagnostic labs.
