The Ultra Low-drift (ULA) is the ideal spray nozzle for pre- and post-emergence herbicide applications, where drift reduction is paramount. A unique thick spray pattern, measuring nearly 60° front to back, coupled with the 120° wide spray angle, enables the boom height to be lowered to further decrease drift potential.

4. Ultra Low Drift (ULD)
Coarser sprays like ULD are ideal for soil applied agrochemicals where foliar wetting is not important
They can also be used on larger targets where the chemical moves within the plant

Guardian Air (GA)
Managing drift using forward speed
3 bar at 12 kph = 100 l/ha at optimum spray quality for coverage
1.5 bar at 8 kph = 100 l/ha at 3 star Lerap (>75% drift reduction)

8. Guardian Air (GA)
A finer air inclusion sprayed straight down is effective in reaching weeds and stem bases in cereal crops
GA nozzle is also ideal for wheat ear spray fungicides where there is often only a small weather window

11. Guardian Air Twin (GAT)
A twin 30° inclined spray with finer air inclusion droplets is effective in getting into crop canopies for fungicides and desiccant applications
It is also effective at getting spray coverage onto all the sides of soil clods and ridges

12. Air Induction Nozzles – Droplet size ranking
Beware!
There are big differences between AI nozzles
Larger
We will take a closer look at one of the bar charts. It basically ranks different types of AI nozzle according to the droplet size they produce, larger at the top and smaller at the bottom.
The Hypro Guardian Air and Guardian Air Twin (GAT) consistently deliver the finest droplets of any AI nozzle and are approximately a 1/3 rd the size of the largest the Teejet TTI
So if your overriding concern is drift reduction then you should use one of the nozzles in the top half of the list. If on the other hand you want drift control combined with efficacy equivalent in most cases to a standard flat fan you should choose a nozzle from the lower portion of the chart.

An inclined 80⁰ spray angle gives a similar spray pattern as a 110⁰ spray angle spraying straight down
A narrower spray angle reduces the proportion of finer droplets
Inclined spray 110⁰ angle

This field of Linseed has been sprayed with just one post emergence grass weed Herbicide. The sprayer used was fitted with two types of nozzle
Vertical 17.5 Blackgrass heads/m2
Inclined 6.3
Blackgrass heads/m2
Here is further evidence of the success of angled nozzles in a trial site in Cambridgeshire.
This field of Linseed has been sprayed with just one post emergence grass weed Herbicide. The previous year the field had been used for Wheat.
The sprayer used was fitted with two types of nozzle – on one half of the boom standard flat fans were fitted and on the other, nozzles having the same spray angle and flowrate but with a 40 degree forward facing incline were fitted. So to repeat the only difference between the two half's of the boom is the angle of incline.
The black lines outline the tramline and you can make out a higher density of mature brownish coloured black grass on the left – the side of the boom fitted with standard flat fans. The right hand side, fitted with the angled nozzles is much cleaner leading us conclude that the angle of incline improved contact and therefore control.
