The wild blueberry industry is an economically important and significant sector with approximately 51,800 ha in production, producing 98.7 million kg in the Atlantic provinces and Quebec with farm gate and processed values of approximately $176.6 million and $369 million respectively. The proposed research will examine the impact of fungal diseases Monilinia and Botryis blight on the structure, function, growth, and development of wild blueberries. Wild blueberries are managed using naturally occurring populations of sweet lowbush (Vaccinium angustifolium) and sour-top (Vaccinium myrtilloides) blueberries containing different shoot growth and development characteristics and also varying levels of resistance to these diseases. Given this, efforts will be made in the proposed research to map the population structure of wild blueberry fields through the use of unmanned aerial vehicles, determine the relatively susceptibility of blueberry phenotypes to the fungal diseases, identify the resistance mechanisms being used in deterring the diseases and determine the impact of the diseases on blueberry growth and development. This will be complimented with studies examining the delivery, deposition, mobility and persistence of conventional disease control products, and also developing reduced risk disease management practices that will reduce fungicide usage and improve fruit quality. Findings will be culminated into improved predictive disease models, diagnostic and disease control technologies and production system sustainability. It is anticipated that the proposed project will reduce agrochemical usage by 30% and reduce the cost of production by 20%. The proposed project addresses key research priorities established by producer associations and the industry sponsor, will enhance the research capacity of Dalhousie University, and provide an essential vehicle for the training of highly qualified personnel. Dissemination of research results will occur to all producers and stakeholders in the sector through platforms including field days, twilight meetings, web based mechanisms including the Wild Blueberry Information Network, scientific symposia and meetings, and scientific and technical articles.

野生蓝莓产业是一个重要的经济部门，在大西洋省份和魁北克省的生产面积约为51800公顷，产量为9870万公斤，农场大门和加工价值分别约为1.766亿美元和3.69亿美元。本研究将探讨真菌病Monilinia和Botryis blight对野生蓝莓的结构、功能、生长和发育的影响。野生蓝莓的管理使用天然存在的低丛甜蓝莓和酸顶蓝莓，它们具有不同的茎部生长和发育特征，对这些疾病的抗性水平也不同。鉴于此，拟议的研究将努力通过使用无人机绘制野生蓝莓田的种群结构，确定蓝莓表型对真菌疾病的相对易感性，确定用于阻止疾病的抗性机制，并确定疾病对蓝莓生长发育的影响。除此之外，还将开展研究，检查常规防病产品的输送、沉积、流动性和持久性，并制定降低疾病风险的管理做法，减少杀菌剂的使用，提高水果质量。研究结果将最终用于改进疾病预测模型、诊断和疾病控制技术以及生产系统的可持续性。预计拟议的项目将减少30%的农用化学品的使用，并将生产成本降低20%。拟议的项目涉及由生产者协会和工业赞助者确定的主要研究优先事项，将提高达尔豪斯大学的研究能力，并为培训高素质人员提供必要的工具。研究成果将通过各种平台传播给该行业的所有生产者和利益相关者，包括实地日、黄昏会议、基于网络的机制（包括野生蓝莓信息网络）、科学专题讨论会和会议以及科学和技术文章。
