Okra / Bhindi (Abelmoschus esculentus L.)

Fusarium wilt (Fusarium oxysporum f.sp. vasinfectum)

Symptoms

  • The first symptoms of the disease are clearing of the vein lets and chlorosis of the leaves.
  • In field, yellowing of the lower leaves first and affected leaflets wilt and die. The symptoms continue in subsequent leaves.
  • Plants become stunted and die.

Management

  • The affected plants should be removed and destroyed.
  • Crop rotation with a non-host crop such as cereals helps to reduce the disease inoculum.
  • Soil solarization before preparation of nursery bed
  • Seed treatment with Trichoderma viride or Pseudomonas fluorescens (20 g/litre of water/ kg of seeds) and its soil drenching is very effective.
