Answer:

Certainty Herbicide can be used on established warm season grasses to control actively growing weeds. Ideally you would want to use it while the grass is still dormant, or after it has greened up completely to avoid any extra stress on the lawn. Grasses that go dormant in winter are most sensitive during their transition periods so this is why its recommended to avoid spraying during this time. If you find you need to treat during the transition, be aware some temporary discoloration or stunting could occur.
