No arctic bramble cultivars known to be resistant to downy mildew are available." However, there are some cultivars that are less susceptible to infection. A few rose and blackberries have been found to be more resistant but breeding and other control methods need to be put in place.
No arctic bramble cultivars resistant to downy mildew have been discovered, but some types of roses and blackberries exhibit reduced susceptibility. Developing new cultivars through selective breeding and implementing additional management strategies are necessary to mitigate this problem.
