Abstract

A three-year trial was carried out in order to study the long-term dynamics of foliar concentration of two fungicides belonging to the SBI (Sterol Biosysnthesis Inhibitor) and QoI (Quinone outside Inhibitor) groups, the most important active substances used in controlling Cercospora leaf spot. Fungicides were applied following the usual schedule, with three sprays per season at 20-day intervals. Foliar concentrations of both fungicides were tested after 1, 3, 9 and 18 days after application. Results showed that the foliar concentration of these substances changes according to fungicide characteristics, application time, time elapsed after distribution, and size of sugar beet canopy. These results suggest new approaches for applying fungicides to control Cercospora leaf spot epidemics.
