What to look for

    Paddock

  • Damage is most severe in short, semi-leafless varieties.

    Plant

  • Indefinite areas of yellow then straw-coloured lesions on the leaf,stem, and tendrils.
  • Numerous pinhead-sized fruiting bodies develop, scattered over the surface of the diseased tissue.

Where did it come from?

  • Fungal spores produced on last year's field pea trash infect nearby crops.
  • Splattering or windblown water enhances the spread of the spores during the growing season.
  • The disease begins on lower foliage, and occurs primarily on ageing foliage, stems, and pods.

Management strategies

Rotation
Rotation
  • Control measures are usually not warranted because the disease appears to have little impact on yield.
  • Crop rotation is the most important control measure.
