Diagnosing seedling root rot in field peas

Root rots caused by Fusarium spp, Pythium spp and Phytophthora spp are major problems in some regions of the eastern states, particularly where crops are grown on stored soil moisture, but these diseases are rare in Western Australia.

 

Rotted roots

What to look for

    Paddock

  • Areas or scattered seedlings that fail to emerge or wilt and die, or survive but lack vigour.
  • Symptoms are worse where plants are stressed, such as cold wet areas of a paddock.

    Plant

  • Sudden death or yellowing and death of older leaves that progresses up the plant
  • Poorly developed and rotting root systems. Symptoms include root browning, pruning ,soft watery lesions.
  • Roots on Fusarium wilt affected plants appear normal, but the interior of the tap root and often the stem is light orange to brick red.

Where did it come from?

  • These are natural soil fungi that persist in the soil for many years

Management strategies

  • Use high vigour seed.
