Conclusion

In a single field trial with sugar beets, rust has been the predominant leaf disease, control strategies with one, two or three applications using either solo products or tank mixture have been studied at two lifting times. At both lifting times, 26 October and 22 November, the highest yield increase and net income are seen with two treatments, and the results indicate that tank mixture (0,3 liter Comet pro + 0,55 liter Propulse) gives slightly higher additional yield and net income than treatment with the solo products 0,55 liter Propulse followed by 0,3 liter Comet Pro per ha. More trials with different times of harvest as well as control strategies with reduced dosages should be carried out to be able to draw more confident conclusions.
