Organic Control Measures to Manage Wilt Disease in Tomato

If your tomato plants are yellow and wilt on one side of the plant or one side of a leaf, they may have Fusarium wilt. This disease is caused by a soil-borne fungus called Fusarium oxysporum sp. lycopersici, which infects only tomatoes. It is a serious disease which causes 80% yield loss under favorable conditions. The fungus is widespread in India, especially in warmer areas, and can survive for a long time in any region. The disease is more likely to occur in soils with high nitrogen and low potassium levels, as well as in sandy soils.

  • Type of Infestation: Disease
  • Common Name:  Fusarium wilt
  • Scientific Name: Fusarium oxysporum f.sp. Lycopersici
  • Category of Plant Disease: Fungi
  • Mode of Spread: Soil borne
  • Most Affected Plant Part: Leaves and stem

Environmental factors favorable for disease development:

  1. Temperature: Fungi can grow at 15-30°C whereas it starts sporulation causing infection at 20-25°C.
  2. Relative Humidity: Highest sporulation is noticed at 90-95% of relative humidity.

Most affected states in India:

Rajasthan, Gujarat and Uttar Pradesh


  1. Initial Symptoms: when fungi enter through the root, it starts blocking and browning of vascular bundles and hampers the movement of water and nutrients to the sink. So we can see yellowing and withering of leaves
  2. Severe Symptoms: as disease progresses, leaves start dropping before maturity. Drying and partial or complete death of plants.
