Abstract
Abstract A field experiment was initiated to determine herbicidal activity on large crabgrasses ( Digitaria sanguinalis (L.) Scop.] when core cultivation was performed in a common bermudagrass [ Cynodon dactylon (L.) Pers.] turf after herbicide application. Core cultivation treatments were made prior to preemergence herbicide application or at 1, 2, 3, or 4 months after the chemicals were applied. Where oxadiazon (4.4 kg·ha −1 ), bensulide (11.2 kg·ha −1 ), bensulide + oxadiazon (6.7 + 1.7 kg·ha −1 ) and benefin (3.4 kg·ha −1 ) were applied, the timing of core cultivation had no significant influence on preemergence large crabgrass control. DCPA (14.0 kg·ha −1 ) was ineffective in controlling large crabgrass, regardless of core cultivation parameter. Chemical names used: 3-[2,4-dichloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2(3 H )-one (oxadiazon); 0 ,0- bis (1-methylethyl) S -[2-[(phenylsulfonyl)amino] ethyl]phosphorodthioate (bensulide); N -butyl- N -ethyl-2,6-dinitro-4-(trifluoromethyl)benzenamine (benefin); dimethyl 2,3,5,6-tetrachloro-1,4-benzenedicarboxylate (DCPA).
