Rhizoctonia solani

Rhizoctonia Solani is the most common cause of seedling blight
Prolonged exposure to cold, very wet or dry soil, deep seeding and short crop rotations encourage infection
Seeds fail to germinate and become soft and pulpy or they germinate and become soft and pulpy or they germinate but seedlings fail to emerge
Seedling roots decay and the rot extends up into hypocotyl and stem at the soil surface, causing the seedling to topple over
Typical wirestem appearance
In dry conditions, shriveled stem may persist
Under wet condition, the seedling is destroyed in a few days
Seedling blight may be scattered throughout fields or in patches, particularly on knolls or in depressions
By the two to four-leaf stage, seedlins can withstand light to moderate infection and regenerate new rootlets
Generally causes poor stand establishment

Scouting:

Just after emergence, look for areas of fields that exhibit severe stand reduction and scout those areas for symptoms of blight or damping off
