Symptom |
-
Symptoms vary and include rapid death of young succulent plants.
-
Discoloration of taproots, longitudinal cracks of the stems, stunting, wilting and poor yields.
-
Complete control of root rot and damping off is difficult, and no variety of cowpea is resistant to root rot.
-
Persistent damp weather prior to development of the first true leaf and also the crowding of seedlings due to poor seed spacing may increase damping off.
Management
