Botrytis (grey mould)

Botrytis cinerea

Grey fuzzy mould on stems, leaves, and fruit. Croptimus catches lesions before they sporulate and re-infect the canopy.

  • Fungal
  • Necrotic
  • Cool + humid
  • Wound-entry

Signs Croptimus looks for

  • Brown necrotic lesions on stems near pruning wounds
  • Grey fuzzy sporulation on dead tissue
  • Soft watery lesions on fruit or flowers
  • Leaf collapse around lesion margins
  • Spore puff release on touch

Recommended action

Reduce relative humidity below 85 % overnight, increase airflow through the canopy, and remove infected tissue before sporulation. Croptimus highlights infected zones so removal is fast and targeted.

Botrytis is the “opportunistic” fungus of greenhouse production – it lives on dead and wounded tissue, then jumps to healthy plants once it sporulates. The economic damage comes from fruit infection: a single lesion on a ripening fruit halves its marketable value.

Croptimus monitors pruning wounds and senescing tissue continuously, so the first lesion gets flagged before sporulation. Removing the infected tissue at that point stops the cycle.

Frequently asked

  • How does Croptimus tell botrytis apart from other moulds?

    The model is trained against multiple grey-mould lookalikes including Alternaria and Cladosporium, using both colour, texture, and growth-pattern features.

  • Can it detect stem lesions vs leaf lesions?

    Yes – the model uses separate sub-classes (botrytis_phytophthora_leaf and botrytis_phytophthora_stem) so action recommendations can be specific to the affected plant part.

  • What's the typical detection lead time?

    2–4 days before visible sporulation, depending on humidity. Lower humidity slows sporulation and extends the detection window.
