| Abstract/Contents: | Benefin 2.5 G, bensulide 4EC, DCPA 75 WP, oxadiazon and siduron 50WP were applied at recommended and reduced rates to plots that had received the same herbicide the previous year. Benefin (2.2 + 2.2 kg ai/ha), bensulide (8.5 and 4.3 + 4.3 kg ai/ha) and oxadiazon (4.5, 2.2 + 2.2 kg ai/ha) provided exceptional, season-long control of crabgrass (Digitaria ischaemum (Schreb.) Muhl.). Data indicated that no significant residual effect was provided by bensulide, DCPA and siduron from the previous year. Plots receiving 2.2 + 2.2 kg ai/ha benefin did not provide an acceptable level of control in 1980, but when the same plots were similarly treated in 1981 over 95% control of crabgrass was achieved. Application of 2.2 kg ai/ha oxadiazon to plots treated with 4.5 + 4.5 kg ai/ha in 1980 provided 100% control of crabgrass in 1981. Studies were also conducted to assess efficacy of benefin, bensulide and DCPA when compounds were subjected to either immediate or 72 hour delayed post application irrigation. Delaying irrigation reduced efficacy of bensulidide more than DCPA or benefin. Preemergence activity of DCPA, however, was markedly improved when watered-in immediately after application. there was no difference in level of control provided by benefin regardless of post application irrigation schedule. |
