The abundance of Avena sterilis in dryland barley fields
was studied in four Spanish provinces. During two
growing seasons, differential geopositioning system
(DGPS)-geo-referenced A. sterilis infestations were
obtained in 31 fields. The majority of the infestations
were concentrated in few large but irregularly shaped
patches, with a higher number of smaller and more
regular patches accounting for a small proportion of the
infestation. A multitude of very small and irregular
patches completed the inventory. The implications of
this spatial structure were studied. Site-specific adjusteddose
herbicide application offered 61–74% potential
herbicide savings. However, given the low levels of
infestation and the low economic returns obtained in
most of the provinces, the most profitable strategy was
generally no herbicide application. Site-specific treatments
were advantageous only in high-returns systems.
Because few large patches provided the majority of the
infestation, zone-specific treatments would be advisable,
until such time that weed detection and site-specific applications technologies become more efficient.
