Spring Insecticide Options for Sarracenia and VFT Thrips

Terri sought ready-to-use alternatives to discontinued Ortho Systemic for spring thrip control on young pitchers/VFTs. Asked about Ortho Rose & Flower (acetamiprid) or Bayer Rose & Flower (β-cyfluthrin + imidacloprid), soil contact safety, and spray duration.

Both Products Are Fine

Soil contact is fine—imidacloprid is used as soil drench in some formulations. Follow labels. Podcast on CP-safe insecticides: YouTube link.

Critical Imidacloprid Limitation

It does not kill thrips or spider mites. Agricultural overuse created resistance. Only spray when infestation visible—prophylactic use breeds resistance.

Nuclear Option: Acephate

Ortho Systemic's active ingredient (acephate) available online as powder concentrate (e.g., AM Leonard, 1 tsp/gal). Nasty stuff—reserve for severe outbreaks.
