Why urea phosphite vs. potassium phosphite
Clemson University research (2025): At equivalent application rates, Prudent Turf increased root mass vs. potassium phosphite and the untreated control
- Promotes foliar uptake and movement for quick response
- No added potassium salt load when K is not desired
- Cleaner tanks and lines with reduced scale and residue
