Hi guys, a quick last request for any help on this before I go for the trial and error method?..any advice? cheers, Mike
Its not trial and error, you just need to do your calibrations - if you have done the course, you should have it in the books they gave you.
Basically jug test your sprayer out put for 1 minute, and measure your walking speed in metres per second. you know your sprayer gives a 0.6m swath (strange choice of nozzle in my opinion- why not using green standard herbicide nozzle?). Then you can work out your area coverage and you will know how much herbicide to use per tank!
Hi Adam,
Thanks for your reply, obviously trial and error was a poor choice for an expression as it's been taken far to litterally!.
I've done all of my spary tickets and successfully been applying herbicides for the past 18 years so completly understand the process of calibration, thanks for the tips though!!
I was mearly trying to save myself the time by asking my original question.
A spray regulator will give the same amount of pressure and using a 0.6 nozzle is a clear choice when spraying off building/path edges to achive a neat result without wasting chemical..
therefore if anyone was using the same setup (Hardy bp20, sorry forgot to say which sprayer originally) it would be an easy ratio for me to use.
cheers for the reply again though, was definately helpfull, have a good weekend
Good work Adam!
Unfortunately, sometimes a bit of "trial and error" has to be done where you're not treating a large unobstructed area where you can keep to your "0.6m swathe" "walking speed in metres per second" Once you start navigating round obstacles, vegetation you don't want to treat, etc etc, the calibration soon goes out the window.
