Reduce the risk of suffering costly pathogen outbreaks that destroy yields.

Whether you’re growing one plant or thousands, Farmer Freeman’s virus detection assay for cultivators will identify plants infected with hops latent viroid (HLVd) using our high quality RT-qPCR testing.

Signs your plants may be infected with HLVd:

  • Curling or yellow leaves
  • Brittle stems
  • Smaller leaves with lighter node spacing
  • Smaller, looser buds with fewer trichomes
  • Overall loss of quality and yield (dudding)

Prevention is key

Screen your plants and incoming clones regularly.

Screen mother plants to ensure they are virus-free before taking cuttings.

Sterilize your equipment before working on each plant.

Note: Samples must be free of trichomes – samples from flowering stage plants will not be accepted.
