Insektmonitering og varsling for skadedyr
Konklusion
Ugentlig monitering af skadedyr og varsling for eventuelt bekæmpelsesbehov er i samarbejde med Nordic Sugar udført i 11 marker bejdset med Force 20 CS i perioden fra april til juli 2021. Der blev konstateret tripsangreb over skadetærsklen fire steder på Lolland og Falster. Runkelroebilleangreb blev konstateret flere steder, med to steder over skadetærsklen. Bladlus var ikke et problem i roer i 2021.
Conclusion
Between April and July 2021, weekly monitoring of pests was carried out in collaboration with Nordic Sugar in 11 sugar beet fields treated with Force 20 CS seed coating. At four of the sites thrips damage has been found above the control threshold. Damages from the pygmy mangold beetle have also been found to a limited extent, with only two sites exceeding the damage threshold. Aphids were not a problem in sugar beet in 2021.
