Frequent rains over the last three weeks have left many pockets of wet soils in fields, which increase the risk for seedling blights to occur.

Seedling blights are prevalent when cool, saturated soil conditions persist after planting. These conditions favor germination and infection by many of the organisms that cause soil-borne diseases. Cool, wet soils also slow plant growth and development and give diseases more time to infect and damage the seedling.
