| Abstract/Contents: | "Turf quality on a putting green is damaged when grown under shade stress. In the southeast the traditional use of bermudagrass on putting greens has a major characteristic of being less tolerant to shade stress. The plant growth regulator trinexapac-ethyl, can lessen negative responses of turfgrasses to shade. The purpose of this research was to determine the shade tolerance of 'Diamond' zoysiagrass (Zoysia matrella) when maintained under putting green conditions with and without the use of trinexapac-ethyl. The study included three levels of shade: none (0%), low (60%), and high (90%). The three levels of shade were applied continuously to all plots using a neutral density, poly-fiber black shade cloth. Two treatments were within each level of shade. One included the application of trinexapac-ethyl with a CO2 backpack sprayer at a rate of 4.77 L ha -1wk-1 (1.5 oz/ 1000ft2 wk-1) operating at 20 GPA with an 8003 flat flan nozzle. The second treatment was absent of trinexapac-ethyl application. Application of shade was initiated on 23 May 2008 and removed 30 October 2008. Plot size was 2m by 1.5m maintained at a height of 45cm above ground level to maintain proper airflow. Shade tents were removed 3 hours weekly to take measurements and perform maintenance. Visual turf quality ratings were taken bi-weekly beginning on 23 May 2008 and ending on 30 October 2008. Ratings were based on a 1-9 scale, with 1 representing dead turf and 9 representing flawless turf. A turf quality rating <7 was deemed unacceptable. In the final visual rating on October 30, 2008 acceptable turfgrass quality resulted from 0% shade with and without trinexapac-ethyl and 60% shade with and without trinexapac-ethyl. Unacceptable turfgrass quality resulted from 90% shade with trinexapac-ethyl. Dead turf resulted from 90% shade without trinexapac-ethyl." |
