Per page 3 of the product label of Trimec 992 Broadleaf Herbicide, adding spray additives such as adjuvents or tank mixtures may alter the selectivity of the herbicide and may increase the likelihood that you will injust desirable plants. Drive XLR8 should always be applied with an appriopriate surfactant, preferably one with methylated seed oil, such as Dyneamic Surfactant. Please refer to the product label for complete instructions. It would probably be best to apply these herbicides separately, however, we would recommend that you do a small compatibility test mixture before applying herbicides together that are not specifically recommend on the product labels. We would also suggest you test a small area of turf before applying both herbicides so that you do not cause excessive injury to your desirable plants.
