Sprayer nozzles

Currently using 1104 fan jet teejet nozzles for spraying grassland weeds and rushes. Getting fed up of the wind recently and having to stop by 9 in the morning. What low drift nozzles would you recommend for 200l/ha. Are air induction nozzles as good for rushes? Never bothered looking at nozzles before and do some help the chemical adhere to the plant better.?
 
what Speed are you spraying at?
Air induction does help but what chemical are you applying. Have you considered using an cold press oil additive?

There’s no perfect answer

Mind you around here you won’t find a tee jet xr. I haven’t used one in over a decade.

We run Lecher IDK nozzles.

Vote for lechler idk’s for grassland spraying, used to be pleased with them doing grassland too. Theyre made of strong plastic and they’re a coarse spray so want to be working at least 2.5bar but they always did a good job on weed kill.
Using bubblejets / guardian airs on the crops now instead

Spraying 7 to 9 kph.

Excuse my ignorance, but what is the theory behind bubblejets?

They’re air induction nozzles too, believe its just a brand name.
Billericay Farm Services call theirs ‘billercay bubblejets’ (BBJ’s)
Hypro make guardian air

I really like bubblejets, especially into a crop canopy they seem to have a wet spread pattern that doesn’t seem too coarse and I don’t know how it doesn’t drift.

I found Lechler Idk’s produce a noticeably coarser spray at low pressures but that’s good if it gets windy on open grassland slow down and drop pressure to 2bar it’s a coarse pattern but it doesn’t drift and it always got a good kill.
If you want a fine spray mist then wind the pressure up to 4 bar

Air inclusion nozzles are certainly better for reducing drift, and I don’t suppose there’s that much difference between Guardian Air and Bubblejets in the real world.

I’m guessing you’re not spraying hundreds of acres a year (?), so hard to justify spending a fortune on nozzles. Search round and see which can be had on offer. There’s usually one or the other available cheap somewhere. I use Guardian Airs at 150 L/ha for almost everything now.

Most grassland sprays advocate minimum of 200l/ha. Do you find you still you get as good a kill?

Yes, but I try to only spray grassland weeds when they are ideal for killing.
You can crank up the pressure to put 200 L/ha through the Blue GA nozzles, it just means you get a finer spray and lose the advantage of reducing drift.

Billericay Bubble Jets were the first air inclusion nozzle introduced to the spraying market in the early 90's. They suck in air with the liquid flow resulting in 75% less drift, by reducing the number of smaller driftable droplets.The larger droplets have air bubbles in them that help them to splat on the leaf instead of bouncing off to be lost.
Lot more environmentally friendly and perfectly suitable for grassland weeds. I use the 025 lilac at 6 kph giving 200 litres at 3 bar pressure. Often just spot treating the bad patches.

The chemicals are so expensive that its worth spending a few quid on a decent set of low drift bubblejets. I don't want to see my spray moving 5m and missing the target, or killing hedgerow plants. You're right though about a deal - they can be had if you look around. @SimpersTradeCounter worth a try.

By ‘not spending a fortune’ I meant get some GA or Bubblejets, which can be bought fairly reasonably, as opposed to some of the suggestions of 3D Defy or twin nozzle air inclusions.

Totally agree on better to hit the target than drift onto everything nearby.👍
