Calibrate and keep your equipment clean and repaired .

Depending on whether you are spreading dry or spraying liquid. If using a spreader usually it's a case of making passes either too far apart(most common) or making passes to close, (triple overlapping, not so common). Having ports in your spreader clogging or not open will effect the distribution pattern. Lesco's spreader has a tendency to spread more to the right than to the left unless your adjusting the flow from the adjustable port with the slide plate underneath. When spraying with a liquid the same problem with pattern can occur with not making passes close or too far apart. too many that spray have a tendency to look down and point the nozzle too much toward the ground making a more concentrate pattern in the center of he path they are walking and not getting the pattern back to where the previous pass was made. Likewise the triple overlap problem can occur as well with spraying to far over the previous pass. Speed of app can effect pattern too, by making to much spray applied going uphill while going to fast when going downhill, not that common simply because most that have been doing treatments for any length fo time avoid the up/down scenario by applying with the hill when possible.

The correct way to do it is do half rate in one direction and do the other half at a 90 deg. angle from the first. For granular. Liquid its best to use a marker dye in your tank so you can see where you have sprayed.

If you want to spread correctly, you need to calibrate yourself with your spreader(s) and sprayer(s). These pages will give you an idea on granular Spreader calibration (http://www.members.aol.com/groundkprs/calibration.html).

There is also a proper procedure for calibrating liquid sprayers, whether a single nozzle on a backpack or multiple nozzles on a boom.

Jim, would you mind sharing that, or pulling it up if you have already. Thanks

Mac, I haven't written anything of my own on it. Best bet would be a Google of "sprayer calibration", and pick out the state university sites. Many of them are cumbersome to read, but then everything seems cumbersome when you first do it.

Basic premise is that you measure quantity sprayed over a given area, in order to get your gallons of spray per 1000 ft² with various spray tools and machines. Then you know what proportions to mix at and how much to mix for a specific job or jobs in any type of application device.

Liquid calibration is generally a lot easier than granular, because you just work with water and don't have to sweep it up. But with liquid you must be more critical - each spray nozzle must be checked for proper pattern. Minor wear can drastically change coverages. Tee Jet and others make special calibration equipment for spray tips - when you get into higher production work they are well worth it.
