Herbicide damage becomes visible within a few days after a pesticide application. Turf may be scorched or die in spots. Leaf blades may be spotted. Actual leaf symptoms may vary according to product, but damage usually occurs in the patterns in which the herbicide was applied.

Prevention and management

Follow all directions on pesticide labels. Check to make sure that the herbicide you choose is registered for use on your species of turf and is effective against the weed you are trying to control.
