Spatial and temporal dynamics of weed populations

Abstract

Spatial and temporal variations in weed seedlings distributions often occur in arable fields and can be assessed and mapped Weeds Mapping using modern sensor- and information technologies. Both management and site-characteristics can result in the heterogeneity of weed populations Weeds Populations. When site-specific weed managementweed management decisions were taken based on distribution maps a high potential for herbicide savings was calculated. It was found that for many weed species distribution remained stable over time when site-specific herbicidesherbicides applications were realized based on economic weed thresholds Economic threshold level.
