I applied it 2 1/2 weeks ago as directed for max. effectiveness and added a little detergent to mix which I was told was a good thing to do by sales rep. It took a week before any noticeable effect and now has done pretty well on most weeds, brush,and vines but has not had any or very little effect on some others. Nothing much is completely dead yet. Hope it continues to work until everything wiped out.
1st time user of Crossbow. Applied late summer. Many wild violets started wilting within a a few weeks. No loss of fescue. Easy to apply with tank sprayer. Will spray again in spring when actively growing. Happy with product at this early stage.
