Applikationsverfahren gegen die Restverunkrautung in Zuckerrüben

Even in modern sugar beet production systems the control of remaining weeds may cause problems. One important reason is the so called spray shadow. To estimate the potential performance of different application techniques, the spray distribution quality of four sprayers was investigated under field conditions. Image analysis was used for evaluation. Results show broadcast spraying is not suitable for herbicide treatments in sugar beets at advanced crop development. Purpose-built underleaf sprayers or droplegs deliver good results to a later date as well.
