Agricultural harvesting machine with pre-emergence weed detection and mitigation system

A method performed by an agricultural machine, the method comprising:

• obtaining a weed seed movement model that models movement of weed seeds during a crop processing operation that engages crop in a field and moves the processed crop to a harvested crop repository;
• identifying a weed seed area based on the weed seed movement model;
• and
• generating a control signal associated with a pre-emergence weed seed treatment operation based on the weed seed area.

A control system for an agricultural harvesting machine, the control system comprising:

• at least one processor;
• and
• memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the control system to:
• control crop processing functionality of the agricultural harvesting machine to engage crop in a field, perform a crop processing operation on the crop to obtain processed crop, and move the processed crop to a harvested crop repository;
• identify a weed seed area indicating presence of weed seeds based on a weed seed movement model that projects likely locations of the weed seeds given a location of one or more weed plants in the field that produced the weed seeds;
• and
• generate a control signal associated with a pre-emergence weed seed treatment operation on the weed seeds, prior to emergence of the weed seeds, based on the weed seed area.
