  • Spread by spores in air; thick-walled spores for survival in soil, on plant debris, on seed.
  • Cultural control: prune to encourage air flow; remove infected fruits from trees, and ground; harvest and transport carefully; avoid storage at high humidity; if possible, store <10°C; clean packing shed, and use clean bins.
