| Abstract/Contents: | "Turfgrass colorants have become widely used for golf and sports turf applications in recent years, and numerous options exist which range from short- to long-term in nature. While in the past, colorants were used primarily to offer color during transition or dormancy periods, they are increasingly being used to enhance turf aesthetics even during growing season. Although a limited amount of data exist, effects of colorants on turf health are beginning to be better understood. One area of limited research involves the impacts of colorant products on absorbance, reflectance, and transmission of photosynthetically active as well as ultraviolet radiation. Laboratory experiments and chemical analyses were conducted with a range of colorant products during 2017 and 2018 at Texas A&M University, College Station, TX. Spectral impacts of fourteen turfgrass colorants were determined, including long-term colorants Brite Stripe, Match Play Ultradwarf, Green Lawnger, Dormant Green, and Endurant Premium, and short-term colorants Turf Screen, Vision Pro, Transition HC, PAR SG, Endurant Turf Enhancer, Turf Mark Blue, as well as fungicides containing colorants (Appear, Interfacer Stressgard and Civitas). This project characterized the effects of turfgrass colorants on light transmission at both UV (200-400 nm) and photosynthetically active radiation (PAR) (400-700 nm) wavelengths by using a Stellarnet Spectroradiometer. Results demonstrated that all spectral transmission differed based on chemical makeup of the colorant. Long-term colorants led to higher reductions in PAR than short-term and fungicides containing colorants." |
