What are most using these days? Used to be sub 100lit/ha and flat fans but thinking of buying some new nozzles and wondered what others were at. And no don’t get excited won’t be going for quite a while!

What are you trying to hit? Small weeds in a young crop? Fungicide in July?

A compromise between drift control and number of droplets for a small target could be achieved with angled nozzle caps alternating front and rear facing and Bubblejets at 150-200 l/ha at high pressure. If it’s windy, you can always slow down or lower the water volume to drop the pressure down to the 3* drift rating.

Normally use 015 flat fans but this year I’m trying some cheap low drifters, yellow I think that give 96 litres at 3 barg 10k fine spray quality in the hope that a bit more actually reaches the ground. Just hoping the orifice plates don’t bung up with gunge.
Not sure when I’ll be going with these temperature extremes. Rubbish is growing fast though.

The problem with beet sprays is they don’t work work so well at lower concentrations, hence the low volume PITA. 200 litres fine spray doesn’t work as I found out one year.

Agreed. Some pillock fitted rotary 4 way changeovers on my HiLo before I bought it, but they're too big for the boom setup so wont rotate!
My poverty spec hi lo has single body units so have to change every nozzle. I bought a set of new caps to try to make it easy but the bodies have swelled out making it impossible to get the new caps on. As it’s always “the last year” for the beet I can’t justify multiple nozzle bodies especially on a 33 year old sprayer.
 
I've been told by several people that BFS ones are superior, so may try them when replacement is due. But to be fair, I really can't fault the Guardians.
I had a new to me sprayer for this year,was fitted with 04 guardian airs (how old they were I dont know but told they wernt that old)
I had bought a set of bfs 04s last year and kept them so tried a section on the new sprayer along side the GA on a windy day in the yard
To my untrained eyes the bfs were far superior.
The ga seems to just spit and there was a fine drift hanging around
The bfs just seemed a good even pattern with nothing floating about
I wasnt long getting a few extra bfs to fill the rest of the boom up!
