In late March the area was vertically mowed, raked and seeded with crabgrass. Initial treatments were applied on June 8 when the crabgrass had reached a 2 to 4 leaf stage. Later treatments were applied on July 20 when the crabgrass was at a 3 to 4 tiller stage. A total of twenty-three treatments were applied to individual 6 foot by 10 foot plots in three replications. The area was maintained at 1.5 inches and irrigation was provided only as necessary to prevent dormancy. Tables provide % crabgrass control on 6/29, 7/27 and 8/31 for herbicides applied at 3 leaf stage and on 8/31 for herbicides applied at 3-tiller stage. Herbicides, herbicide combinations, formulations, and application rates are also provided. MON 15104, 1EC, at 0.75 #ai/A gave best control at 3-leaf stage while Acclaim 1EC, at 0.25 #ai/A gave best control at 3-tiller stage.
