In 1997, some wheat and durum seed rotted prior to germination because of Penicillium mold. This seed was planted into very dry soils that did not get rain for some time. Protectant or systemic seed treatment products could have protected the seed from seed rot. Seedling blight occurs after germination when fungi either on the seed itself or in the soil attack the emerging seedling. Seed infected with the scab fungus or black point fungi often get seedling blight if not protected by seed treatment.
Seed sitting in wet soils or cold soils also are more vulnerable to seedling blights.
Seed treatment products may be protectants, systemic products, or combinations of protectant and systemic fungicides. Common root rot was a severe problem in some fields in 1997, especially those with short rotation periods between susceptible crops of hard red spring wheat, durum and barley. Seed treatment reduces the risk of severe damage. Check labels of products for crops allowed. Loose smut of wheats and barley may be a problem any year.
