Horticultural crops :: Flowers :: Chrysanthemum

Wilt: Fusarium oxysporum f.sp. chrysanthemi

Symptoms

  • Initial symptoms are in the form of yellowing and browning of leaves.
  • Affected leaves die from the base of the plant upward. Infected plants are stunted and often fail to produce flower.
  • Wilting may cause rotting of root or the base of the stem.
Browning of leaves Stunted plant Infected stem

Management

  • Before planting dipping the rooted cuttings in a solution of Pseudomonas fluorescens @2g/litre of water.
  • Since the disease spreads mostly through cuttings, it is important to use disease free planting material.
  • Disease can further be minimized by following strict sanitation; periodical monitoring; crop rotation and roguing of infected plants.
