the science behind biocat pst
what are bacteriophages?
Bacteriophages (or "phages") are naturally occurring viruses that specifically engage with and reduce bacterial populations. They are the most abundant biological entities on Earth, found in every environment where bacteria exist — including agricultural soils. Unlike chemical antimicrobials, phages are highly selective: each phage targets only specific bacterial species, leaving beneficial microorganisms unharmed.
BIOCAT+ PST formulations contain carefully selected bacteriophage communities that target pathogenic and growth-inhibiting bacteria commonly found in agricultural soils. When applied, these phages integrate into the soil ecosystem and function as a self-regulating biological control.
When harmful bacterial populations rise above healthy levels, the phages activate — selectively reducing those populations back to equilibrium. When balance is restored, phage activity naturally subsides. This responsive, cyclical mechanism means BIOCAT PST adapts to the soil's own biological rhythms rather than imposing a one-size-fits-all chemical intervention.
how biocat pst works
what this means for growers
The result is a healthier, more balanced soil ecosystem that supports stronger root development, more efficient nutrient cycling, improved disease resistance, and enhanced crop performance. Because BIOCAT PST works biologically rather than chemically, it is compatible with organic certification programs, integrated pest management systems, and conventional growing operations alike.
regulatory classification
BIOCAT PST products are classified as soil conditioners — not pesticides — reflecting their mechanism of action as biological ecosystem enhancers rather than direct pathogen-killing agents.
