How much longer before yellow colored patches turn green after using Tenacity Herbicide?

I applied Tenacity as a preemergent the first week of March. 2 weeks later there are large straw colored patches. To date surrounding areas are green and patches are still there.


It depends on what type of turfgrass Tenacity Herbicide was applied to. If the grass is labeled tolerant to the product then it will bounce back as long as it's a healthy lawn. We would recommend to contact your county extension office to identify if it's a disease.
