Today, Ventura County Cooperative Extension's Maren Mochizuki shares with us about 
a local research project.

Armillaria mellea is a fungus that causes root rot in citrus, peach, and many other edible tree and landscape species. UCCE Farm Advisors Jim Downer and Ben Faber are investigating the effect of soil disturbance, organic matter, and Trichoderma (another soil fungus) inoculation on survival of peach trees planted in soil infested Armillaria mellea.  Preliminary results were presented on Aug. 4 at the ASHS annual conference in Palm Desert, CA.
