In 2015 we evaluated the efficacy of OARS PS in providing winter hydration to putting greens. Our focus was to provide research based facts that OARS PS could provide the following for turfgrass managers:
Moisture Management Solution
Multi-branched Hydrating Surfactant
PBS150 is a long-term surfactant utilizing a unique multi-branched molecular structure to address the source of performance loss – biodegradation of the surfactant molecule by soil microbes. PBS150 sustains a longer uniform soil moisture profile.
A uniform supply of water within the soil profile is critical during heat and water stress periods to meet the transpirational demands of the plant. Equally important, is the need for a uniform supply of water to turfgrass roots during a period of recovery and repair. Without a sustained supply of water, the turfgrass plant will be unable to rebuild its root system and carbohydrate (sugar) reserves (needed to survive dormancy and for subsequent new growth requirements).
The ability of PBS150 to improve the uniform soil moisture status of turfgrass offers the turfgrass manager a highly flexible surfactant system from which to address these two critical periods of successful turfgrass management — Heat and Water Stress and Turfgrass Recovery.
• Reduces hydrophobic conditions on a sustainable basis for 5 months or more
• Encourages a pattern of hydration and re-hydration that improves the amount of available water in the soil profile to meet the metabolic demands of the plant
• Restores the uniform movement of water into and through the soil matrix
• Improves stress tolerance

Fairways, Tees, and Sports Turf
100 Day Moisture Management: Apply two applications 15 days apart at 5 ounces per 1000 ft² in 2 gallons of water (16 L/ha in 800 L). Reapply 90 to 100 days after last treatment or as needed.
150 Day Moisture Management: Apply three applications 15 days apart at 5 ounces per 1000 ft² in 2 gallons of water (16 L/ha in 800 L). Reapply 120 to 150 days after last treatment or as needed.
Bunker Faces, Collars, Roughs, and Lawns
Apply two applications 7 to 10 days apart at 8 ounces per 1000 ft² in 2 gallons of water (25 L/ha in 800 L). Reapply after 120 to 150 days or as needed.
Irrigate with sufficient water to deliver PBS150 to the soil profile – 1/8 inch (3 mm) or more recommended.
Fairways, Tees, Bunker Faces, Collars, Roughs, Lawns, and Sports Turf
Single Application: (75 Day Moisture Management)
Apply 4 lbs per 1000 ft² (200 kg/ha). Reapply after 60 to 75 days or as needed.
Split Application: (150 Day Moisture Management)
Apply two applications 7 to 10 days apart at 4 lbs per 1000 ft² (200 kg/ha). Reapply a split application after 120 to 150 days or as needed.
Irrigation is necessary to release PBS150 from the carrier. Irrigate before next mowing or leave baskets off.
Evaluation of two commercially available wetting agents on soil moisture management
Evaluation Time Frame:
March 30, 2016 to August 8, 2016, 132 Days
Penn State University, Joseph E. Valentine Turfgrass Research Center
Trials were conducted on native soil fairways. Applications were made at label recommendations. Three applications of PBS150 regenerating multi-branched surfactant were made at 5 ounces per 1,000 square feet. Three applications of an industry leading modified/methyl-capped block copolymer surfactant were made at 6 ounces per 1,000 square feet.
Evaluation of PBS 150 regenerating multi-branched surfactant and an industry leading modified/methyl-capped block copolymer surfactant on soil moisture management of an L-93 creeping bentgrass grown on a native soil fairway. Target moisture level was 35% Volumetric Water Content (VWC). Rewetting of the matrix occurred once 25% VWC was measured. Both measurements were completed using a Spectrum TDR 300 Moisture Meter. The dry down was initiated on June 8, 2016.
PBS150 plots required 36% less water than the control plots maintained at 35% VWC. 36% less water is equivalent to 1,470,150 gallons saved for 25 acres of fairways in an 8 week period. PBS150 outperformed the industry leading surfactant by saving 6% more water and required less watering cycles than the control.
