I was planning to combine quinclorac and trimec together. Quinclorac recommends this surfactant, but the Trimec label to my understanding suggests not using a surfactant. I am thinking if I combine the two herbicides I should not use the surfactant.
No, Prime Source Duo Stick Select should not be added to Trimec as it already has a small amount of surfactant in it.
