After a 2 year fight with the Commonwealth of Virginia, I am now, finally, a licensed Commercial Applicator. I have some ??? though. I have the following equipment: 30 gal, 12V tow sprayer with an 8' boom and wand. 125 lb tow behind spreader. (2) 50 lb push spreader. I tried the big ones, and I just don't want to push around 100# of fertilizer. 4 gal BP sprayer for glyphosate. (2) 2 gal HH sprayers for selectives. What I want to know is this: What else should I plan to buy soon? Are sprayers (generally) more efficient than spreaders? (cost and time) How many treatments can I reasonably expect to add to an existing 4 day schedule? At what point in the future should I expect to be looking for a spray rig? What should I add to maintenance agreements for lawn treatments? When is the best time to advertise for this part of the job? What's the best way to store chemicals on the truck if they aren't going to be used right away? Thanks in advance for any help some of you veterans can give me and maybe keep me from repeating your mistakes.
