Cleveland C. Cleary <br />52773 Ash Rd. <br />Granger, In 46530 <br />Supporting Documentation for APSA-80 vs. LESCO-Wet Liquid Wetting Agent. <br />The point of surfactants, regardless of formulation, is to lower the surface <br />tension. APSA-80 takes the surface tension down quickly to just over 30 dynes at <br />30.8 p,pm, or about 1 oz. in 100 gallons of water. <br />For approaches, tees and greens on golf courses or other heavily trafficked turf, <br />we recommend 1 oz. per 1000 sq ft every month at a cost of $0.47. For active dry <br />spot we recommend 2.5 oz. per 1000 sq ft at a cost of $1.18. For fairways, rough, <br />and other areas we want to keep greener longer we recommend 15 oz. per acre <br />per month at a cost of $7.05. If it is possible to get it on while the turf is still <br />dormant in the spring, we recommend starting with a double dose, then regular <br />doses monthly. <br />Following is the LESCO-Wet Liquid Wetting Agent label showing the application <br />rates; the concentration chart and subsequent surface tension for APSA-80; and a <br />quad fold brochure, the APSA-80 for turf is listed on the last fold. <br />
