A spray nozzle comprising a nozzle body ( 110 ) having an air channel in fluid communication with an air supply, and directing air to one or more air openings ( 160 ) at an end of the nozzle body, and a liquid channel in fluid communication with a liquid supply and directing a liquid to a liquid outlet ( 150 ) of the nozzle body. An air cap ( 120 ) is disposed at the end of the nozzle body and has an orifice in fluid communication with the one or more than one air openings, the orifice is disposed about the outside of the liquid outlet. The spray nozzle also comprises an extension ( 170 ) placed on the liquid outlet, outlet protrudes beyond the surface of the air cap. The spray nozzle is well suited for use under windy conditions in that fouling of the nozzle is reduced or eliminated.
