Notes:
Poa pratensis L.) were established outdoors and moved inside a covered-stadium simulator facility (CSSF). Four rates of flurprimidol (0.56, 1.12, 1.68, and 2.80 kg ha-1) were compared against a control. Studies were conducted under ambient (equivalent to 2-3% full summer sunlight) and supplemental (equivalent to 9-18% full summer sunlight) irradiance. The turf was evaluated with and without simulated soccer traffic. Under ambient irradiance conditions, turf quality generally declined to unacceptable levels within 30 d, although the low rate of flurprimidol extended this period for up to 60d. Supplemental irradiance provided turf of acceptable quality for up to 70 d and the low rate of flurprimidol extended this period for 〉 100 d. Applications repeated within 30 to 40 d virtually stopped measurable shoot growth under all irradiance and traffic regimes. Flurprimidol did not affect turf shear resistance or rooting but did increase tillering. Low rates of flurprimidol should be useful for maintaining turf in reduced irradiance conditions because turf quality is enhanced with minimal risk of phytotoxicity.
