Powdery mildew is one of the costliest grapevine diseases in New Zealand and an increasing challenge for growers from both an economic and sustainability lens. It reduces grape yields, drives up vineyard management costs, and degrades wine quality, leading to significant economic losses. Researchers at Scentian Bio will investigate the use of VOC sensing to provide early detection of powdery mildew. Early detection would be a gamechanger, enabling better control strategies and new control solutions – this could include targeted spraying (only when needed and only for affected vines) as well as new biological controls that are better suited to earlier stages of infestation.
