Performance Phosphite

Macro-PHITE™ is a double-action plant protection phosphite fertilizer formulated to increase resistance to biotic stress caused by pathogens and abiotic stress caused by adverse climatic conditions.  Macro-PHITE™ contains phosphite derived from potassium hydroxide and phosphorous acid.  It is root and shoot-absorbed, highly mobile within the turf plant and enhanced with Macro-Sorb amino acids for superior product uptake.  Macro-PHITE™ is also fortified with specific amino acids designed to facilitate the production of SAR (systemic acquired resistance) proteins, which are specific proteins that develop in response to biotic and abiotic stresses.

Product at a Glance: 
  • Taken up by plant roots or shoots - Highly mobile within the plant
  • Macro-Sorb amino acids promote efficient uptake and elevates natural defense mechanisms within the plant
  • Excellent tank mix compatibility
  • Amino acid complex provides phosphite stability for maximum efficacy

Apply 1.0 – 1.5 oz. per 1000 sq. ft. every 14 – 21 days for maintenance applications before the onset of biotic or abiotic stresses.  Apply 1.5 – 2.0 oz. per 1000 sq. ft. every 7 – 14 days when environmental conditions favor turfgrass stress.  Apply with enough water to uniformly distribute Macro-PHITE™ to turf canopy.
