Effect of Broadleaf Weed Herbicides in Combination with MACRO-SORB® foliar for the Control of Dandelion
Dr. T. L. Watschke & J. A. Borger
This study was conducted at Penn State University, University Park, PA on a mixed turfgrass consisting of fine fescue, Kentucky bluegrass, and perennial rye with a heavy infestation of dandelion. Treatments were applied on September 12, 1997. The experimental design was a randomized complete block with 3 replications and a plot size of 3 x 15 ft. Treatments were applied on September 12, 1997 and percent control of dandelion was rated on November 13, 1997.

Results and Discussion
Half rates of commercially available herbicides for the control of broadleaf weeds combined with MACRO-SORB® foliar controlled dandelion on turfgrass as full rates did.
