Sprayers are mostly used for weed killing.
To optimise herbicide application, 2 critical factors must be met :
- localisation of the zone to avoid product migration onto the neighbouring plants
- adequate droplet size to reach the plants to be destroyed, thanks to a continuous
pressure of around 1 bar.

Spray shields: protecting plants
To spray a localised zone and avoid spray drift, two types are available:
- a compact round shield (18 cm diameter) to select a localised zone, next to plants
and flowers
- a wide shield (38 cm) for spraying inter-row or along a path (vineyard,
plantations...) safely and efficiently

Lances can be used for weeding more comfortably, without bending.

The lances and telescopic lances offer convenience and safety for all situations where it is crucial to reach high targets such as trees (in winter and after flowering) or roof treatments (e.g. moss treatment).
Light, rigid and resistant (both on a chemical and mechanical level), standard and telescopic lances come complete with nozzle : enabling you to equip your standard sprayer for high treatments with precision and comfort.

Lances :
Extension of the hand and arm, ideal for remote targets such as tall fruit trees.
Available from 0.5 m to 2.0 m

Go to Lances

Telescopic lances :
More compact extensions for distant targets, they can be adjusted to the desired length for a perfect application.

 Loss of pressure at height ?

The pressure out of the nozzle decreases by only 0.1 bar per meter of height, which means that with a 2 m lance pressure output will be reduced by 0.2 bar.
Sprayer pressure output : 3 bar
Pressure output from lance : 2.8 bar


The indispensable accessory for wide spraying.
To pass from a mono-jet to a multi-jet spray, booms are designed to increase capacity and width coverage.
They are particularly good for large surfaces and herbicide spraying.

Lightweight booms ideal for spraying larger areas.

2, 3 and 4 nozzle booms equipped with ISO F-02-110 flat fan nozzles spaced to every 50 cm, ideal for double overlap.
Output per nozzle at 2 bar is 0.65 l/min
Nozzle angle: 110°

Controls and guarantees the right application of product making the nozzle a key-part of any sprayer.

Which nozzle to choose?
A nozzle for every spray job: select the right nozzle to optimize product application and limit the effects of possible drift.
Cooper Pegler offers an extensive range of nozzles:
-anvil or flat fan nozzles for herbicides, for applications around 1 bar pressure
-hollow cone for insecticide and fungicide applications, ideal around 3 bar pressure

For each type of nozzle, you will find different opening sizes and angles in order to choose the right output for the recommended rate. These factors influence your speed of coverage over the field and your ability to spray "on time"; critical issues that will affect the quality of your application and the dose you may have to use.

Volume rate (l/ha) = Flow rate (l/min) x 10,000 / Size of treatment area (m) x speed (m/min)

Go to Nozzles

Choosing the right nozzle ensures the right coverage and flowrate.
Examples of width and volume treatment rate using anvil nozzles

Check the flowrate of each nozzle each year: it must be homogeneous. If it differs by more than 10% from the theorical flowrate at a precise pressure level, the nozzle has to be changed.
