Eutypa dieback is also known as?

Explanation:
This question tests whether you know the common name used for Eutypa dieback in grapevines. Eutypa dieback is commonly called Dead Arm because the infection causes dieback of the vine’s cordon arms, leaving sections of shoots dead and forming cankers in the wood. The other names refer to different diseases: Black Rot affects fruit and leaves, Powdery Mildew is a white powdery fungus on foliage, and Grey Rot is Botrytis cinerea causing mouldy fruit. So Dead Arm is the best answer because it specifically describes the characteristic dieback of the vine’s arms associated with this disease.
