Verticillium Wilt

Asked July 9, 2019, 7:10 PM EDT

Has there been any success with "cooking" soil with plastic to kill the verticillium wilt fungus? I've been losing plants in a specific area of my garden including an indian plum, kinnikinnick and a 15' blue elderberry. The plants die within days of showing symptoms. I'm certain that verticillium wilt is the cause. Located in Tigard. Thanks.

Verticillium wilt advice currently doesn't include solarization. "Curative measures for Verticillium wilt do not exist, so control tactics should be aimed at preventing the disease." This statement is from the PNW Handbook, an Extension publication: https://pnwhandbooks.org/plantdisease/pathogen-articles/common/fungi/verticillium-wilt-pacific-north...
