Abstract/Contents: | Studies were conducted to compare the preemergence, crabgrass [Digitaria ischaemum (Schreb.) Muhl. and Digitaria sanguinalis (L.) Scop.] control effecacy of experimental herbicides with commercially available compounds. The herbicides alachlor 4EC, butachlor 5EC, MON 97 8EC, MON 4621 4F, UC 77892-B 5G, UC 77892 80W, and UC 82042 4E and 8G did not provide effective (i.e. > 90%) levels of season-long preemergence crabgrass control. UC 77892 80W (4.5, 5.6, and 6.7 kg/ha) applied when crabgrass was in the 1 to 3 leaf stage, however, provided excellent postemergence control and subsequently effective preemergence control of crabgrass. A single application of DCPA (11.8 kg/ha) provided satisfactory crabgrass control in 1981 and 1982, but not in 1983. Benefin 2.5G (3.4 kg/ha) and oxadiazon 2G (3.4 kg/ha), evaluated in 1983, provided 92.6 and 99.5% crabgrass control, respectively. MON 4621 caused an objectionable yellow-brown discoloration in 'Manhattan' perennial ryegrass. |
