Infected kernels are shrunken, wrinkles an light in weight, with a rough scabby appearance. Infected heads lead to premature bleaching while the healthy heads remain green in the field. Infected seed looks shriveled and chalky white.

Description

The infection of the fungi takes place at or after flowering. Seed that is infected and used to plant a crop the following year can introduce the fungi into disease-free fields.

Damage Description

Infected kernels are shrunken, wrinkles an light in weight, with a rough scabby appearance. Infected heads lead to premature bleaching while the healthy heads remain green in the field. Infected seed looks shriveled and chalky white.

Infected seed will result in significant reduction in germination. When infected seed is planted, seed-borne Fusarium will negatively impact emergence and overall seed performance causing seedling death. For every seed that is visually damaged by Fusarium there can be many more infected seeds without visual symptoms.
