Abstract/Contents:"CGA-163935 (proposed common name cimectacarb) is a growth regulator being developed for vegetative inhibition of warm- and cool-season turfgrass. CIBA-GEIGY Corporation conducted an Experimental Use Permit (EUP) program in 1991 with CGA 163935 to evaluate plant growth regulator effects on eleven turfgrass species. The EUP program was conducted on golf courses, sod farms, and commercial and residential lawns. Rates of CGA-163935 tested ranged from 300 to 950 g ai/ha, with rates dependent on species treated and duration of activity desired. In the northeastern United States, EUP trials were conducted in New York, Pennsylvania, Connecticut and Ohio. Cool-season turf species treated in these trials included bentgrass (Agrostis palustris Huds.), Kentucky Bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), perennial ryegrass (Lolium perenne L.) and fine fescue (Festuca spp.). Parameters measured in the EUP program included mowing reduction, clipping weights, color, and general turf quality, as well as tank-mix compatibility and methods of application. The 1991 CGA-163935 EUP program confirmed the effectiveness of this compound in reducing the frequency of mowing and the amount of grass clippings produced over a wide range of turf species and situations. Applied to mixed spp. home lawns in Pennsylvania, cumulative growth was reduced by 50% and number of mowings by 20% when averaged across four sites. In Connecticut, CGA-163935 applied to bentgrass fairways reduced total clipping volumes from 48-60% over four week periods. Normal germination and establishment of bentgrass was observed when overseeded 2-5 days after applications of CGA-163935. Differential tolerance of annual bluegrass (Poa annua) vs. bentgrass to CGA-163935 indicates that this compound may be useful in a Poa reduction program. No incompatibilities with tank-mixes or application methods were noted."
