Mosaic virus

Tomato mosaic virus · Cucumber mosaic virus

Mottled yellow-green leaf patterns caused by viral infection. Croptimus flags suspect plants for isolation before insect vectors spread the virus.

  • Viral
  • Insect-vectored
  • Systemic
  • No cure

Signs Croptimus looks for

  • Mottled yellow-green leaf pattern
  • Leaf curling and distortion on young growth
  • Stunted plant growth
  • Reduced fruit set
  • Fruit mottling and uneven ripening on infected plants

Recommended action

Isolate and remove infected plants immediately – viral infections cannot be cured. Control insect vectors (whitefly, aphid, thrips) aggressively to prevent spread. Croptimus flags suspect plants by zone and row for fast removal.

Viral infections in greenhouse crops are catastrophic – there’s no treatment, only isolation and removal. The longer infected plants stay in production, the more vector insects (whitefly, aphid, thrips) carry the virus to healthy plants.

Croptimus’s zone-level isolation flagging turns viral outbreaks from “replant the block” into “pull those three plants today”. That’s the difference between recoverable and unrecoverable losses.

Frequently asked

  • Can Croptimus distinguish mosaic from nutrient deficiency?

    Pattern + leaf-curl signature. The model uses the characteristic mottle pattern (rather than the diffuse interveinal yellowing of deficiency) to identify mosaic with high specificity.

  • Does it identify the specific virus species?

    No – species-level identification requires ELISA or PCR. The model flags "mosaic virus suspect" so the grower knows when to send leaf samples to a lab.
