Fungicide Selection for Carnivorous Plants: Safer Alternatives to Bayer Natria

Bayer Natria now uses Bacillus subtilis (same as Serenade) instead of sulfur. It's safe for Sarracenia but test on flytraps—it's toxic to some sundews. Its short residual activity requires frequent reapplication.

Preferred preventative: Safer Brand Garden Fungicide (sulfur-based), available in ready-to-use and concentrate. It's effective, CP-safe, and longer-lasting. Always test any new product on a single plant first.
