Implement Crop Rotation: A rotation system helps reduce the population of the verticillium and fusarium fungi in the soil, thereby controlling the disease.
Pesticide
Fungicide Application: Applying fungicides can control fungal pathogens. The specific fungicide depends on the causal organism and should be applied per the manufacturer's instructions.

When is Leaf wilting Most Active Period on Rutabaga?

The disease is most active during warm, damp seasons when fungal pathogens thrive. Dehydration-induced wilting is often seen during dry, hot periods due to evapotranspiration exceeding water absorption.

Infectivity

Lethality

If left untreated, leaf wilting can cause a significant reduction in plant vigor, yield, and can eventually lead to plant death.
