  • Cutting the base of the stem revel a dark woody portion.

Management

  • Continuous cultivation of okra on the same piece of land should be avoided.
  • Seed treatment with Carboxin 37.5% + Thiram 37.5% @ 2-3 g/kg of seed OR  Thiophanate Methyl 45% + Pyraclostrobin 5% FS @ 2 g/kg of seed.
  • spray and drenching with Thiophanate methyl 70% WP @ 400 g/acre.
  • Azoxystrobin 18.2% + Difenoconazole 11.4% SC @ 200 ml/acre.
  • RFor bio management, apply Trichoderma viridae for soil application and foliar spray. It controls all types of fungal infections in the crop.
