Bladsvampebekæmpelse i økologi

Slutsats:

I to økologiske sukkerroeforsøg er produkterne Kumulus S, 1901SC, Charge og Bion undersøgt for deres
effekt ved bladsvampebekæmpelse. Kun Kumulus S er godkendt i økologiske sukkerroer.
I gennemsnit af de to forsøg i 2022 er der ikke sikre forskelle i opnået udbytte mellem behandlingerne, men
der er tendens til 3-5 procent merudbytte ved behandling med 3 x 7 eller 4 x 3,5 kg Kumulus S samt 3 x 5
l/ha Charge. Merudbyttet kan ikke dog ikke betale for behandlingerne i årets forsøg. I gennemsnit af fire års
forsøg ses behandling med 4 x 3,5 kg/ha Kumulus S at medføre 4 procent merudbytte, som er rentabel, men
denne dosering er dog ikke godkendt.

Slutsats:

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.
