Ukrudtsbekæmpelse – dysevalg ved båndsprøjtning

Conclusion

Herbicide treatments are carried out with different nozzles, in order to find the optimal method for weed control in bands over the sugar beet rows. Weed control between the rows is carried out with two times row harrowing. The treatments are carried out with half the dose of NBR’s standard strategy for weed control. Due to the generally good effect of weed treatments in 2022, there has generally not been a significant difference between the different nozzles for row spraying on the result of the sprayings. In one of the three trials, there was a significantly better effect in the rows of the row spraying compared to the broad-sprayed entries. In general, a lower effect has been achieved where nozzles with coarse droplets have been used compared to fine droplets.
