Got my license middle of this year so this is first time for me to spot spray. Using granular program. I can talk with the local Lesco manager about these questions but I wanted some real world answers about Speedzone before I buy it and then ask the Lesco manager the questions. 1. Labeling says 'To prevent separation of the emulsion, mix thoroughly and continue agitation while spraying. This product forms an emulsion and can separate upon extended or prolonged standing.". I have a Shurflo electric backpack sprayer. Is walking around while spraying enough to 'continue agitation' or will I need to get another type of backpack sprayer or ?. 2. It has Dicamba in it but not much (0.67%). Can I spot spray under tree line as long as I don't spray on surface roots? 3. Label also mentions 'delay mowing 2 days before and until 2 days after the application of the product'. Do you follow this quote or is it alright to spray just after you mow? Does grass clippings really effect the product that much from getting on the weeds?
