Integrated Pest Management Options
Seed Treatment
Fusarium begins as small, reddish-brown lesions on the taproot
that join to form larger lesions, or streaks, as the plant ages.
The lesion can extend up to the soil line. The splitting of the
tap root, crown and lower stem often reveals a brown-reddish internal
discoloration of the water-conducting tissue.
Longitudinal cracks and adventitious roots may develop on damaged
plants. These adventitious roots are formed above the damaged area.
Late infection seldom results in dead plants but rather in stunted,
unthrifty-looking ones. Disease development is promoted by soil
compaction, short crop rotations and moisture stress.
Due to the threat of anthracnose infection to this crop, ALL
edible bean seed should be treated with DCT or Dynasty 100FS. See
ANTHRACNOSE (Colletotrichum lindemuthianum), opposite
page, for more details. Other seed treatment products may be needed
to protect against other edible bean diseases.
