Anthracnose Control in Apple

Apple anthracnose (bull’s-eye rot) causes bark cankers and a stubborn fruit rot that often appears in storage, turning up as sunken bull’s-eye lesions weeks after picking. Wet, mild autumns favour it in orchards.

Common crops affected

Why it matters

It rots and downgrades fruit and defoliates plants, returning from debris each season; early protection keeps fruit clean.

When to act

Protect through wet autumn periods and pre-harvest; manage cankers by pruning.

What to look for

  • Sunken cankers on twigs and limbs
  • Bull’s-eye lesions on stored fruit
  • Cracked, oozing bark margins
  • Storage losses appearing post-harvest

How to manage it

  1. Remove infected debris and fruit; avoid overhead watering.
  2. Apply Spore Control (1:1,000) at first sign and during warm wet spells.

Recommended Vegalab program

Spore Control — encapsulated adherent cover; rainfast.

Frequently asked questions

Why does rot show up in storage?

Latent infections from the orchard develop in the cooler — pre-harvest protection reduces stored-fruit loss.
