Dyna-Phos is a liquid formulation designed for soil application as a drench or irrigation supplement. It is comprised of orthophosphate, a readily available form of phosphorus that will stimulate root growth and lower the soil pH.
Dyna-Phos should be applied as a soil drench or injected through the drip or micro-irrigation system at a rate of 1 to 2 gallons per acre. When used as an irrigation line cleaner, Dyna-Phos should be applied at a rate of 2 gallons per 1000 gallons of water to lower the in-line pH below 2.0. Dyna-Phos is not recommended for foliar application.
