Abstract/Contents:"CGA-163935 is a growth regulator being developed by CIBA-GEIGY Corp. for vegetative inhibition of warm- and cool-season turfgrass. CGA-163935 reduces cell elongation by inhibiting giberellin biosynthesis. Major turfgrass species such as St. Augustinegrass (Stenotaphrum secrundatum [Walt.] Kuntz), bahiagrass (Paspalum notatum Fluegge), Bermudagrass (Cynodon dactylon L. Pers.), tall fescue (Festuca arundinacea Schreb.), perennial ryegrass (Lolium perenne L.), red fescue (Festuca rubra L.) and Kentucky bluegrass (Poa pratensis L.) have shown activity from applications of CGA-163935. Effective use rates vary form 200 to 1000 g ai ha-1 with excellent crop safety. Factors which influence optimum use rates include turf species, application timing, environmental conditions and duration of desired inhibition. Following application, reduced foliar growth has led to reduced number of mowings, clipping weights per mowing, stolon growth and seedhead production. For example, a single application at 800 g ai ha-1 reduced the number of mowings of St. Augustine, bahiagrass, and bermudagrass 66%, 57% and 33% respectively, for a period of six weeks and tall fesccue (fescue) were reduced 50% for seven weeks."
