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.
- 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.
