Ross from Small Town, Ia writes
I want to spray for both weeds and bugs in one pass. If using Speed Zone or Trimec 992 and a Surfactant will it diminish the results or have an adverse affect on the herbicide?
Sometimes herbicides and insecticides can be mixed depending on the molecular makeup of the products. Since both Speedzone and Trimec 992 are made by PBI Gordon we recommend contacting them at 800-821-7925 to verify that these products can be mixed with Tempo SC Ultra. As far as the surfactant, it will not make a difference. You can add a surfactant to both herbicides and insecticide for extra sticking and penetration power.
