If I had my own yard I'd be experimenting all the time lol. I have an apartment though. And yes I spot spray weeds. I don't agree you should broadcast spray herbicide unless it's a pre-em. What's your reasoning there out of curiosity? In my opinion unless you're turf is that full of weeds(in which case you're doing something wrong elsewhere) there's no need for it and it's just a waste of product. My weed rate is about 2 gallons per thousand. I use a 24 gallon tank with an electrical pump, not my skid sprayer... I'm not sure what you mean by the way I do things needs a different plan/technique. And yes I fertilize with dry, but use liquid too. Dry twice a year and liquid twice a year. I actually have two licenses lol. Working on a 3rd for structural pest control. I'm not an expert though. I've only been doing this 2 and a half years, have learned a lot in that time but still have much more to learn. Either way I can see why you'd question me. I don't think I'm coming off right and maybe worded my question wrong. I know how to calibrate equipment. But calibrating it doesn't fix the way I spray. I'm just trying to see other opinions on what people think about the rate I use and what others spray at. I feel like I'm just slow as hell. And how do I retrain myself to spray differently, but still get proper coverage? What's the "right" way to spray if there is one(as far as walking speed and gun movement etc.)? Are you guys that spray insecticides and liquid ferts etc. at 1-3 gallons a k getting good results? As far as my last boss, turf was actually his specialty. He was a very smart guy. But it was a community HOA like where I work now, with 3 technicians including me. So we had plenty of time to spray the way he taught us(well the way he taught 2 of us, the other tech sprayed much faster and wasn't taught by him). It wasn't really an issue. I really don't see a problem with a 10gal/per K rate as far as the grass is concerned(aside from herbicide, obviously that's too much carrier for that). I never questioned it when I worked there. I never had an issue with it, always got good results. It's only an issue for me now because I switched jobs and I'm the only tech and have many more responsibilities there(irrigation for one). I don't have the time to broadcast spray as much as I'd like because I'm constantly filling up so I'm hoping I can speed things up. The biggest reason I'm asking this is because I skipped my wall to wall preventative insecticide app this year due to lack of time and decided I'd spot treat. And now that's coming back to bite me. Seems like chinch bugs are worse than ever this year.
