Has anyone mixed Lesco three way (at 2 ounces/gallon) and Drive 75 (1 ounce/3 gallons) and then did an application, only to find that it also killed the turf grass around the weed? Temperature at the time of the application was around 80. On one lawn, we treated for crabgrass and virginia buttonweed. The customer called two days later and said that her lawn was spotted. We came back and every area we sprayed was dead! Just wanting to see if anyone has had like experiences.
