Method and device for the row-by-row application of plant protection agents

A method for the application of spray liquid containing plant

• protection agents onto rows of plants with an agricultural spraying device that comprises groups of spray nozzles, wherein each group of spray nozzles comprises a multiple nozzle body on which spray nozzles of each group are respectively arranged, wherein the multiple nozzle bodies are arranged on a boom of the agricultural spraying device, wherein the groups of spray nozzles and the spray nozzles of each group are spaced apart from one another perpendicular to a direction of travel of the agricultural spraying device and wherein the groups of spray nozzles include at least three nozzles;
• and a control unit for controlling the spray nozzles, wherein the control unit preferably comprises a microprocessor and/or a data store;
• wherein each group of spray nozzles is individually controllable, and each spray nozzle in one respective group is individually controllable;
• wherein the control unit is embodied to select at least one spray nozzle each from at least some of the groups of spray nozzles by means of control signals, wherein the agricultural spraying device is embodied to apply spray liquid with the selected spray nozzles onto one row of plants each, wherein the application of the spray liquid is accomplished from the selected spray nozzles as a strip application in the form of respective strips, and the application of the spray liquid does not overlap within a nominal spray angle of directly adjacent ones of the selected spray nozzles, wherein in two directly adjacent groups, a distance between outer spray nozzles in each directly adjacent group is equal to a distance between directly adjacent spray nozzles of the two directly adjacent groups, and wherein, in each group of spray nozzles, at least one of the at least three nozzles is arranged between the outer spray nozzles of the at least three spray nozzles on the multiple nozzle body, wherein the method comprises:
• controlling at least one spray nozzle each from at least some of the groups of spray nozzles by means of control signals of a control unit to select the respective spray nozzles;
• applying spray liquid with the selected spray nozzles onto one row of plants each;
• wherein the application of the spray liquid is accomplished from the selected spray nozzles as strip application in the form of respective strips in which the application of the spray liquid does not overlap within a nominal spray angle of directly adjacent spray nozzles of the selected spray nozzles.
