Conclusion

In two organic grown sugar beet trials, the products Kumulus S, 1901SC, Charge and Bion have been
investigated for their effect in disease control. Only Kumulus S is approved in organic sugar beet.
On average of the two trials in 2022, there are no definite differences in the yield achieved between the
treatments, but there is a tendency for 3-5 percent more yield when treated with 3 x 7 or 4 x 3.5 kg/ha of
Kumulus S and 3 x 5 l/ha Charge. However, the additional yield in Kumulus S cannot pay for the treatments in
this year’s trial. In an average of four years of trials, treatment with 4 x 3.5 kg/ha of Kumulus S is seen to lead
to a 4 percent increased yield, which is profitable, but this dosage is not approved.
