Hi Gary
Hypro have a great little booklet with all the info in that you could ever need about nozzles, and possibly some info that you don't need too!! If you want to pm me you address, I will post one out to you

Yep it's the Hypro "Crop Spraying Pocket Guide" you need. Wouldn't / couldn't live without it.
Check there web site at http://www.hypro-eu.com/en-gb/ might have a link for the booklet?

Having read the booklet again on nozzles, I want to ask who uses what nozzle for what type of jobs (not talking about calibrating to get the exact nozzle delivery) & why ?
Hi Gary,
as you know its not what we use, its, what do you want to do? what chemicals etc do you plan to use? what water volume are you looking to achieve and what sprayer do you plan to use?? and where?
Too many people don't know how to spray IMO, and copy others (bit like the school cheat....no good if they've got wrong too) :-)
Perhaps I am not putting across my question clearly.
I am trying to re-fresh team's equipment with possible options for their use out in the field. I am trying to stay above the minutia at the moment. All discussions relate to backpack pedestrian sprayers.
What I wanted to know from people's experience (and without loading the questions ) is ;
- what is deciding factor between choosing Polijet/Lumark flood nozzles vs Deflectip flood nozzles ? Is it purely a 'known' make decision ?
Most pesticides (ie RUP) recommend a coarse spray. I then might select next, width of spray needed for a fence line or kerb line.
- for spot spraying pesticides and/or selectives (?), I would 'naturally' choose a "full cone". Is that what other people would choose or do they stick with a narrow angle flood jet ?
- When, in principle, would one choose a Flat Fan (ie Medium/fine spray)
- My understanding is that you would never select a Fine spray nozzle (of what ever type) to apply pesticide/herbicides.
In these scenarios I am not talking about bulk/large area spraying (like you would perform on a lawn) but tactical spot spraying one would perform on commercial/industrial sites, where you can not / do not work out areas prior to spraying.
Hi Gary,
Have posted you a copy of the booklet today.
This is not professional advice, but when I was landscaping, I had 3 nozzles, one coarse flat fan for all herbicides, one coarse deflector tip for spraying under hedges and one fine flat fan for insecticide or fungicide when coverage was a bit more important!
1/ for the booklet
2/ that is where I was kind of going.....I have someone recently qualified and he's asking lots of questions which has made me review and rethink what We/I do.
Utlimately, we all have to start somewhere with training guidelines and initial experience from other people ;-)

Further researching this topic, I found the following on the Monsanto website (..I know RTFM..:-);
Gives some useful additional criteria for 'Nozzle Choice' (esp re: Flat Fans).
Now, unless I'm mistaken this level of advice was never covered in that much detail in my PA training.
Useful to bookmark this page.....
