Claim 9:
10. An agricultural spraying device that travels in a direction, comprising:
an optical and/or infrared detection unit configured to monitor a field section of a field having plants, an optical axis of the optical and/or infrared detection unit having an angle of inclination greater than 0° relative to a vertical line in a direction of travel of the spraying device;
a control unit including:
a processing unit,
wherein the control unit is configured to:
identify at least one row of plants in the field section being monitored using the optical and/or infrared detection unit;
define a plant region containing the at least one identified row of plants in a specified evaluation portion of the monitored field section using the at least one identified row of plants and an identified weed region different from the plant region;
ascertain a plant value of the weed region in the specified evaluation portion of the monitored field section; and
output a control signal in such a manner that a spray is applied to the weed region of the specified evaluation portion as a function of the ascertained plant value, using spray nozzles of the agricultural spraying device; and

the spray nozzles, the spray nozzles being configured to apply the spray to the weed region of the specified evaluation portion as a function of the ascertained plant value;
wherein, in a direction of travel of the spraying device, a length of the specified evaluation portion is less than a length of the monitored field section; and
wherein a position of the specified evaluation portion in the monitored field section is selected in such a manner that, in the direction of travel of the spraying device, the distance between the specified evaluation portion and the spray region of a following spray nozzle of the spray nozzles is greater than the distance between the monitored field section and the spray region of the following spray nozzle.
