Root rot and Damping off: Pythium, Rhizoctonia, Macrophomina

  • 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.
  • Soil application P. fluorescens or T. viride– 2.5 kg / ha + 50 kg of well decomposed FYM or sand
  • Spot drenching with Carbendazim @ 1 gm/ litre
Healthy and infected root
