1st Question: I'm planning to rebuild a couple spray rigs this winter and I'm wondering what the typical application rate (gals of solution/1ktft2) is for the "hose draggers" here. I'm guesstimating around 2-2.5 is what I would use. 2nd Question: Do you guys apply the same amount (gals of solution/1kft2) for all treatments (pre-m, post-m, fert, insct, fung, etc) and mix accordingly or do you adjust the volume as well. Lawns treatments are only a portion of my business (I plan on focusing on this service next year) and so far all are small, most are <4000ft2. I have just been using an electric backpack sprayer with a boom attachment and applying 1 gal/1k for everything except the occasional fungicide treatment (2 gal/1k). I recently sold some larger treatments for next year 10k, 12k, and 18K so now I have some motivation to get my rigs rebuilt.
