Decision-making processes must indicate if, how, and when weed control should be
practiced. So far, Decision Support Systems (DSSs) for weed control to prevent crop yield
losses can guide decisions on “if” and “how.” Experience shows that farmers need a DSS
that can also guide when to treat, but this can only be done if the actual weed density
observed in the field is known during the crop cycle. Emergence models allow the prediction
of daily density, but precision depends on the survey date. This study focuses on the …
