Anthracnose

Fungal disease causing sunken dark lesions on fruit, leaves and stems of tomatoes, peppers, beans and cucurbits.

Symptoms

  • Circular sunken spots on ripe tomato fruit
  • Tan dead spots on bean pods
  • Reddish-brown streaks on bean stems
  • Dark sunken pits on cucumber and melon fruit

Lifecycle

Splashes from soil onto fruit in wet weather. Worst on overripe fruit.

What to do

  • Pick fruit promptly — overripe is most vulnerable
  • Remove and bag infected fruit
  • Heavy mulch to stop soil splash
  • Copper fungicide as protectant

If it's bad

  • Chlorothalonil (where registered)

Stop it coming back

  • Stake plants to keep fruit off ground
  • Mulch under plants
  • Three-year rotation
  • Avoid working among wet plants
