According to our present experince Corbel is a fungicide at our disposal to control mildew on cultivated dandelion. However the duration of the efficacy is not sufficient. In this case, Desmel shows a better result. Often two - first with Corbel (Fenpropimorph) and after several days with Desmel (Propiconazol) - resulted in distinguishably higher yields. Even better results were obtained in those fields, which were treated once more with Corbel in case of a late infection. Fenpropimorph can be traced 20 days after the last treatment with 0,10-0,78 mg/kg, At the time of harvest (181 to 230 days approx). After last treatment) no Fenpropimorph could be found. The residue situation was judged positively because the period between the last treatment and the harvest covered several months. Moreover not the treated leaves are harvested but the new sprouts in spring.
