I tell them all about it. I still do 6 visits for weeds, etc., I just won't have to fertilize it every time. Selling it is fairly easy when you explain what the product does and that if kept watered properly they will see consistent color without flush growth. About 20% of my acres were applied with SIFI in March and they look fantastic right now. Hopefully this will at least double next year.
None of my commercials spell out how many fertilizations, just the number of visits and that they are to remain green and have good weed control. I don't do any commercials which are not irrigated, so I do not forsee any problems.
