Pythium Root Rot Applications for Pythium root rot should be initiated in late-summer or early fall when the average soil temperature at a 2” depth taken at 11 am declines below 80°F for three consecutive days. These applications should be watered-in with 0.125” of irrigation. Signature TM XTRA can be tank-mixed with any or all of the applications below to enhance plant health and photosynthesis, improve control of Pythium root rot, and help manage resistance. The Envu program below has a satisfaction guarantee and if your expectations are not met, please contact your Envu Distributor or Envu Area Sales Manager.
