Abstract: A method of applying a herbicide to a flood field (1). The method comprises providing an unmanned aerial vehicle (UAV) (2), and flying the UAV (2) along a plurality of substantially parallel spray flight paths (31). The method also comprises spraying a herbicide composition from the UAV (2) onto the surface of the flood field (1) at a plurality of application areas (11), each one of the plurality of application areas (11) corresponding to one of the plurality of spray flight paths (31), each application area (11) being separated from adjacent application areas (11) by a dispersion area (12) into which herbicide composition sprayed onto the flood field (1) surface can disperse. The herbicide composition comprises an aqueous emulsion (EW).
