METHOD FOR SPRAYING, SPRAYER AND HERBICIDE COMPOSITION

The invention relates to a method for spraying spray solution, which method is characterised by that the spray solution is sprayed onto the plants from a lateral direction. The invention also relates to equipment for the realisation of the method, which has a container for accommodating the spray solution, a liquid forwarding unit, at least one nozzle and one or more pipes connecting the nozzle to the container through the liquid forwarding unit, and which equipment is characterised by that it is constructed in a way suitable for changing the exit direction of the spray solution preferably within the angle range of about ± 45° with respect to the horizontal plane, and/or in order to control the exit direction of the spray solution the equipment is connected to the vehicle used for carrying the equipment in a way enabling the alteration of its position with respect to the vehicle. Furthermore, the invention relates to a herbicide composition for killing composite weeds, especially ragweed, which consists of an 8% - 19% aqueous solution of one or more salts and is characterised by that it contains mainly or exclusively potassium chloride as its salt component.
