Assignee: DEERE & COMPANY
Field: Other special machines (Mechanical engineering)
Classification: CPC A  G | IPC A  G

Claim 18:
19. A control system for an agricultural machine, the control system comprising:
a processor configured to:
obtain a weed map of a field including a crop, the weed map identifying a plurality of weed areas on the field,
each weed area, of the plurality of weed areas, being defined in the weed map by a spatial boundary that identifies a relative position on the field of the weed area having weed plants;

apply a movement model to the plurality of weed areas defined in the weed map, wherein the movement model represents movement of weed seeds from a first location on one or more weed plants to a second location in which the weed seeds are detached from the one or more weed plants and deposited on or in a ground surface of the field, and wherein the movement model is based on at least one of:
environment data representing an environment of the field,
terrain data representing a terrain of the field, or
machine data representing machine operating characteristics;

identify, based on applying the movement model to the weed map, one or more regions of the field having a number of weed seeds above a threshold; and

a controller configured to generate a control signal for a pre-emergence weed mitigation operation based on the one or more regions of the field.
