Bruce from Houston, Tx writes

Over applied an application of Tenacity in late spring to my St. Augustine lawn and now the turfgrass is not growing in those areas. Is there a product I can apply to the soil to encourage the St. Augustine to grow.

Answer:

Tenacity Herbicide is not labeled for use on St Augustine home lawns, it is only labeled to be used on St Augustine grown for sod aka commercially grown. Unfortunately, the only way to reduce the effects of an herbicide would be to use an activated charcoal immediately after applying (within hours).

For additional information, please contact the manufacturer at 866.796.4368 since the application was off label
