Spraying apparatus ( 1 ) is provided that has two horizontally disposed upright spray arm assemblies ( 33 ) that each carry sprayers ( 43 ). Each spray arm assembly ( 33 ) has a sprayer ( 43 ) in an upper part ( 35 ) and a sprayer ( 43 ) in a lower part ( 37 ). The upper part ( 35 ) is able to move relative to the lower part ( 37 ) so the axis of spraying from the upper part ( 35 ) will be downwardly directed towards an upper part of crop to be sprayed. The spray arm assemblies ( 33 ) are mounted on respective arms ( 25 ) for moving laterally inwardly or outwardly relative to a longitudinal direction of a row of crop to accommodate for different width crops and/or different crop row widths.
