Abstract/Contents:"The purpose of this study was: (a) to determine effective dosages of pre-emergence herbicides for season-long crabgrass [Digitaria ischaemum (Schreb.) Muhl.] control in the transition zone; and (b) to determine if reduced rates of herbicides applied in subsequent years would provide satisfactory crabgrass control. A single application of bensulide (8.5 kg ha-1) provided effective (>90%) crabgrass control in all 3 years of the study. Oxadiazon (4.5 kg ha-1) effectively controlled crabgrass, and reducing the rate of oxadiazon to 2.2 kg ha-1 in the 2nd year, or reducing the rate to either 1.1 or 1.1 + 1.1 kg ha-1 in the 3rd year also gave excellent crabgrass control. Single and sequential applications of benefin did not provide satisfactory control in the initial year of use. Benefin applied at 2.2 + 2.2 kg ha-1 provided acceptable control in the 2nd year, whereas it was not until the 3rd year that a single application (2.2 kg ha-1) was efficacious. The lowest effective dosage of DCPA was 8.4 + 8.4 kg ha-1; however, consistently good results were provided by 11.8 + 5.9 kg ha-1 of DCPA. Single and sequential applications of siduron did not effectively control crabgrass in any year."
