What environmental condition can promote the spread of Fusarium patch?

The spread of Fusarium patch is significantly influenced by excessive moisture or wet conditions. This fungal disease thrives in environments where the soil is saturated and humidity levels are high. Such conditions create a favorable environment for the fungus to develop and spread, effectively allowing it to infect plants more readily.

While high winds can physically disperse fungal spores, they do not create the ideal conditions for growth and proliferation of Fusarium. Extreme heat and drought conditions are similarly not conducive to the fungus, as they can induce stress in plants and lead to conditions where the fungus is less likely to flourish. In contrast, the consistent wetness from excessive moisture provides the necessary water that Fusarium requires for its growth cycle, leading to an increased incidence of the disease in affected areas.
