Sarracenia flava Deformed Growth: Herbicide Drift or Insecticide Damage?

Barrel of Sarracenia, one flava deformed with brown veiny discoloration. Thought aphids, sprayed repeatedly (pirimicarb), no help. Root parasite? Thrips? Safe treatments?

Diagnosis: Chemical Damage

Jeff Dallas: looks like physical/chemical damage—similar to herbicide drift. Insecticidal soaps cause this in hot weather. Pirimicarb (relative of carbaryl/Sevin, similar to Diazinon) likely culprit, especially sprayed on hot day. Dig up to check rhizome; top-water heavily to flush.

Safe Insecticides Used at Nursery

• Acephate (Orthene)
• Imidacloprid
• Neem
• Permethrin
• Pyrethrins

Avoid insecticidal soaps and oil-based products.

Good Growing!
