Micro sprayers are small, non-rotating sprinklers with flow rates ranging from 20-150 L/hr and the radius of 1.0-3.0 m. The shape of the wetted area varies depending on the type of the spray used. These units are relatively vulnerable to clogging and require fine filtration from 120-150 microns and are mostly used in tree crops.

They are fixed to small plastic wedges 0.20-0.30 m above ground and they are connected to the polyethylene (PE) laterals with 7-9 mm flexible plastic tubes 0.60-1.20 m long, usually placed one per tree 0.30-0.50 m apart or between the trees. Most of them are insect protected.

The manufacturers catalogue usually shows the sprayer type, nozzle colour and diameter, flow rate, pressure, wetted diameter, proposed lateral size, spacing between sprayers and the maximum number of sprayers per lateral. Based on the nozzle colour/size, one sprayer head can be used -by changing the nozzle only - to achieve various application rates and wetted diameters.

Some of the sprayers can operate upside down to reduce the wetting diameter for irrigating young trees and they can be pressure compensating and non drain - attaching a non drip device to the sprayer -, as well (see pictures).
