ZeroTol 2.0 by BioSafe Systems — 2.5 Gallon

When pathogens threaten your crop, you need a solution that works fast. ZeroTol 2.0 is a powerful, broad-spectrum algaecide, bactericide, and fungicide that eliminates plant pathogens on contact — no waiting, no systemic uptake required. Formulated with BioSafe Systems' proven peroxycompound chemistry, it delivers rapid, reliable protection from propagation through finished crops.

Use it as a standalone treatment or tank mix with a systemic chemistry like OxiPhos or an insecticide like AzaGuard to build a comprehensive integrated pest management program for your greenhouse or nursery.
