| Abstract/Contents: | "CGA-163935 is a new plant growth regulator being evaluated for use in northern turfgrasses. Field trials throughout the United States in 1987, 1988, and 1989 showed CGA-163935 has excellent activity and safety on tall fescue (Fesctuca arundinacea Schreb.), Kentucky bluegrass (Poa pratensis L.), perennial ryegrass (Lolium perenne L.), and creeping bentgrass (Agrostis palustris Huds.). CGA-163935 inhibits internode elongation. Uptake is primarily foliar with little or no soil activity. The addition of various surfactants to the spray solution or carrier volumes ranging from 200 to 1,600 L ha-1 has not influenced activity. CGA-163935 inhibited foliar growth when applied within four days before or after mowing. CGA-163935 does not eliminate seedhead production in cool season turf species. Effective use rates of CGA-163935 vary with turf species, ranging from 200 to 800 g ai ha-1. Up to 4,000 g ai ha-1 per year have been tolerated by several turf species without adverse effects. Environmental conditions influence the duration activity of CGA-163935, with the duration of inhibition ranging from two to eight weeks. Multiple applications of the optimum rate at two to four week intervals enhanced the degree and duration of activity. Cool season turf injury due to vehicular traffic was not influenced by CGA-163935. Turf discloration was more common when the turf was growing under stress, including low fertility or moisture, and temperature extremes. Tank-mixing with certain nitrogen- or iron-containing products reduced or eliminated discoloration occurring under stress. In addition to northern turf species, CGA-163935 has reduced foliar growth of several warm season turf species, including St. Augustinegrass (Stenotaphrum secundatum [Walt.] Kuntz), bahiagrass (Papsalum notatum Fluegge), and bermudagrass (Cynodon dactylon [L.] Pers.). CGA-163935 is also being investigated for lodging prevention in small grains and rape." |
