Professional applicators often have little control over mowing. To afford these applicators more confidence when mowing cannot be controlled, we initiated research last fall to determine how mowing around an application affects the efficacy of 2,4-D + MCPP + dicamba on common dandelion.
To test the effects of mowing timing on the herbicide application, turf at each location was mowed at 3 inches 4, 3, 2, or 1 days before treatment (DBT), 1 hour before treatment, 1 hour after treatment, or 1, 2, 3, or 4 days after treatment (DAT). Percent weed cover was visually estimated from 0 to 28 weeks after treatment
Results. Herbicide efficacy was not affected by mowing timing at either location
