I just got my MN pesticide applicators license in the mail, and paid for the MN fertilizer license, I've bought my PROLAWN covered sprayer, and bought my earthway fert. spreader. I've contacted JohnDeere/Lesco to start buying pre, post, weed/feed, and fertilizer. NOW............... Where & What are the record keeping/customer forms I need to fill out when I spray or fertilize a property? - I know it has something to do with wind speed, and exactly what active ingredients were applied to the property. And... they have to be kept for... how many years after applying? -Does it matter that I have a covered sprayer, and there will be no drift? Will surely appreciate any advice, or links to the appropriate documents! THANK YOU!!
