| Abstract/Contents: | "Imazapyr, an experimental PGR of American Cyanamid Co., alone and in combination with imazethapyr (Arsenal), a recently released herbicide from the same company, were applied to mono stands of 'Rebel' tall fescue (Festuca arundinacea), and also to 'Palmer', 'Prelude', and 'Pennant', cultivars of perennial ryegrass (Lolium perenne) on April 29, 1986. Comparisons were made with two commercially available PGR's as well as mowed and unmowed checks. Rates of imazapyr and combinations with imazethapyr controlled seedhead and foliar growth of all four turfgrasses as well as recommended rates of mefluidide did, and better than amidochlor. Discoloration caused by the experimental PGR's was rate related and median doses were similar to that caused by mefluidide. Discoloration was minimal on Rebel tall fescue, but more objectionable at high rates on each of the three ryegrass cultivars. Rebound effects, i.e. increased green color and growth (clipping weights), were more notable and lasted longer with PGR-treated Rebel tall fescue than for the same treatments on many of the ryegrasses. Two later applications of these PGR's, at weekly intervals, on adjacent plots of Pennant ryegrass produced more injury than the earliest application. Severe thinning of the Pennant ryegrass turf resulted from late applications of the highest rates of the experimental materials." |
