Root rot and Damping off

Symptom

The disease cause rapid death of young succulent plants. Discolorations of tap roots, longitudinal cracks of the stems, stunting, wilting and poor yields are symptoms of the disease.

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. (C.O.: Pythium spp., Rhizoctonia spp., Macrophomina phaseolina)

Management

Avoid excessive irrigation. Ensure proper drainage. Remove infected seedlings. Drench the soil and treat the seeds with Trichoderma viride or Pseudomonas florescence (20 gram/litre of water). Spot drench Carbendazim 50 WP (1 gram/litre of water) or Mancozeb 75 WP (3 gram/litre of water).
