| Abstract/Contents: | For two consecutive years certain retardants were applied to the same plots of 'Delta' Kentucky bluegrass and also 'Manhattan' perennial ryegrass under lawn management MH at 4.5 kg/ha, mefluidide at .28, .42, and .56 kg/ha, and MBR 18337 at .14, .28, and .56 kg/ha retarded Delta more effectively without supplemental N in the spring of 1978. Foliar retardation and seedhead suppression of Delta was markedly affected by these treatments in early May while their effects on Manhattan were minimal. The effects of similar treatments reapplied in 1979 were enhanced by mowing one week later. Foliar injury by retardants was nil, but discoloration of turf was greater in mowed plots and this was attributed to the fact that senescent foliage in effective treatments was more exposed because new canopy growth was minimal. Regeneration of roots of 'Park' Kentucky bluegrass from treated plugs was retarded significantly by half the recommended rates of MH (2.2 kg/ha) but only at double (1.1 kg/ha) recommended rates of mefluidide. Manhattan roots were more severely retarded by MH than other chemical retardants. Later in the season only Manhattan treated with MH developed red thread. |
