1. A computer-implemented method comprising:
obtaining a weed plant map of a field including a crop, the weed plant map identifying a plurality of weed areas on the field,
each weed area, of the plurality of weed areas, being defined in the weed plant map by a spatial boundary that identifies a relative position on the field of the weed area having weed plants;
applying a movement model to the plurality of weed areas defined in the weed plant 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;
based on applying the movement model to the weed plant map, generating a weed seed map that identifies one or more regions of the field having a number of weed seeds above a threshold; and
generating a control signal for a pre-emergence weed mitigation operation based on the one or more regions identified in the weed seed map.
