Chlorotic streak disease

Chlorotic streak disease can cause crop losses of 20-30 per cent, with more severe losses occurring in poorly drained soils.

The disease is spread by water and is common in flood-prone and waterlogged soils.

What to look for

  • Irregular creamy-white streaks with wavy margins on the leaves.
  • As the disease progresses, these streaks lengthen and widen.
  • Some sections within the lesion can die.

Management

Chlorotic streak disease can be managed by using disease-free planting materials and improving drainage in low-lying areas. Highly susceptible varieties should not be planted in fields prone to flooding or waterlogging.
