Managing Pierce’s Disease: Key Strategies
Effective management of Pierce’s Disease (PD) requires an integrated approach combining vector control, cultural practices, and use of resistant grapevine varieties. The glassy-winged sharpshooter (Homalodisca vitripennis) is the primary vector, so monitoring and reducing its populations through biological control agents, selective insecticides, and habitat management are critical. Cultural practices such as removing infected vines, optimizing irrigation, and maintaining vine health enhance resistance to infection. Additionally, planting disease-tolerant or resistant cultivars helps sustain vineyard productivity over the long term. The review emphasizes that early detection, grower education, and collaborative research are essential components in slowing disease spread and minimizing economic impact. By combining these strategies, vineyards can implement a proactive and sustainable PD management program.
