Control Options for Greenhouse Cucumber Damping-Off Disease

Greenhouse cucumber plants were transplanted into soil treated in five different ways to test for reduction of damping-off disease. The non-chemical and methyl bromide treatments involved the replacement of a small area of soil around the transplants to allow for maturity of the plants to a less susceptible stage of growth. Untreated fallow field soil, solarized soil, methyl bromide treated soil and metalaxyl soil drench treatments were all effective in preventing infection from Pythium aphanidermatum, the causal agent for damping-off of cucumber seedlings in this Study.
