An important step towards application of variable herbicide rates is the development of online sensors for detecting weeds. Field trials were conducted with a sensor-controlled field sprayer from the year 2000 to 2003 in cereals and pea. The aim was to quantify the influence of the real-time application of variable herbicide rates on the amount of herbicides used, grain yield and late weed infestation. In 13 field trials average herbicide savings of 24.6% were achieved (cereals: 22.8%, pea: 27.9%), and compared with conventional application on average no yield reduction was caused by sensor-based herbicide application. When late weed infestation was checked shortly before harvest, no differences in weed density were observed between areas with reduced and areas with standard dosage.
