Abstract/Contents:"Benefin at 2.24 and 3.36 kg a.i./ha, Betasan at 8.96 and 14.00 kg a.i./ha, DCPA at 11.76 and 16.80 kg a.i./ha, Pendimethalin at 1.68 and 3.36kg a.i./ha and Oxadiazon at 2.20 and 4.00 kg a.i./ha were applied to a high maintenance plot and a low maintenance plot of Kentucky Bluegrass (Poa pratensis L.). The objective of this study was to investigate the effect of preemergence herbicides on rooting of Kentucky Bluegrass. A core sampler was used to take plugs of 2 cm diameter and 20 cm deep 50 days after application. These samples were divided into 5 cm sections to check root inhibition variability according to depth. The roots were washed free of any soil and then oven-dry and ash weights were taken. This sampling was repeated again in 50 days on the low maintenance plot. The only plants showing a decrease in rooting were those treated with Pendimethalin at both the 1.68 and 3.36 kg a.i./ha rates in the first sampling of the low maintenance study. There was no significant differences in rooting found in the high maintenance plot nor was there any differences by depth due to herbicides."
