Rate:

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.

Package Sizes:

6X1 liter (1.58 US gallons) case

12X1 liter (3.16 US gallons) case

120 liter (31.7 US gallons) drum

Macro-PHITE

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

Pythium Blight Observed Following Treatments

Treatments were applied as a foliar spray application (at given rates) every 14 days to Perennial Ryegrass maintained at fairway mowing heights. Macro-PHITE provided exceptional plant health results compared to the standard potassium phosphite fertilizer treatment.

Real-time PCR to Determine Defense Gene Expression

Defense gene expression 1,2, and 4 days following Macro-Phite application

PCR is a common analytical method for determining gene expression in plants.  Following applications of Macro-PHITE, defense genes were expressed, particularly at 4 days after treatment. Notice how the gene PAL is expressed 4 days after treatment of Macro-PHITE compared to the untreated control. PAL (Phenylalanine ammonia-lyase) is a well-known gene that promotes many natural defense mechanisms in plants.
