PAR+

INCREASES EFFICIENCY of PHOTOSYNTHESIS FOR HIGH QUALITY SURFACES & STRESS FREE TURF

WHY CHOOSE PAR+?

How PAR+ Works

5-ALA is a compound that is made by all plants and is at the start of the metabolic reactions that produce both chlorophyll and antioxidants. PAR+ contains 5-ALA and accelerates this process, resulting in greener, stronger turf with enhanced resilience to oxidative stress caused by intense sunlight, shade, heat, cold and disease pressure.

Proven through Research at the World Renowned University of Nottingham, Sutton Bonington plant research centre.

Enhances Chlorophyll Production

Drives more energy capture for denser,greener turf

Improves Stress Tolerance

Supports turf during intense sunlight, shade, heat, cold, drought and salinity pressures.c

Boosts Energy Flow

Increases metabolic activity and nutrient uptake

Proven At a UK University 

PhD level studies verify the effects of PAR+ on turfgrass surfaces

How to use PAR+

PAR+ is supplied a a liquid that also contains photosynthesis promoting micronutrients, and as a high purity white powder.

The dilution rate of PAR+ varies depending on several factors, including turfgrass species, environmental conditions, and the specific stress factors involved (e.g., mowing, drought, compaction). Guidelines for the dilution rates are as below:​

Stress Level               Rate per Ha.       Frequency

Before stress occurs       1L or 10g                 Every 2-3 weeks

Moderate stress              1.5L or 15g              Every 2-4 weeks

Severe stress                    2L or 20g                Every 4-6 weeks

Considerations for Optimizing PAR+ Application​

  • Application Frequency: Lower concentrations (1L per Ha) can be applied more frequently, while higher concentrations (2-3 litres per Ha) should be used less often to prevent over-stimulation.

  • Environmental Factors: In warmer climates or during active growth phases, slightly higher concentrations (1.5-2 litres per Ha) may be needed, while cooler climates may benefit from lower rates (1 litre or 10g per Ha).

  • Turfgrass Species: Some turfgrass species may have different tolerances to PAR+. For example, cool-season grasses (e.g., bentgrass or fescue) might require lower concentrations than warm-season grasses (e.g., Bermuda or zoysia) due to differences in growth rates and stress tolerance.
