Instructions:
Under certain conditions, Drive XLR8 application to annual grasses at 2-tiller and 4-tiller may not provide complete control. A sequential application will be required for grass control in these situations. Optimum control is achieved when applications of Drive XLR8 + methylated seed oil are applied either before second tiller or as grass weeds mature.

Biotypes of large and smooth crabgrass in California have shown varied response to Drive XLR8. If control failure occurs following a full or split application, DO NOT reapply Drive XLR8. Change to a herbicide with a different mode of action.
