SEEDLING BLIGHTS
Description:
Wilting and dying of young seedlings during and after emergence are the first
signs of blight. A soft watery rot of the roots, mesocotyl and crown are typical
symptoms. Seeds with a white or pinkish weft of mold around them indicates
seed rot. Various seed?borne and soil? borne fungi cause seedling blight.
Not to be confused with insect injury. Location: State wide, particularly
in early planted fields or fields with compaction, wet soil or very dry soil
and reduced tillage fields when emergence has been delayed by cold soil. Cold,
wet compacted fields have particular problems with seedling blight. Time
of attack: Blights occur when seedlings are put under stress or are subjected
for extended periods to conditions limiting rapid growth of the young plant.
Generally, April through early May. Management:
· Seed treatment
· Improve drainage
