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经济上重要和重要的部门，产量约为51，800公顷，在大西洋省份和魁北克生产9，870万公斤，农场和加工价值分别约为1.766亿美元和3.69亿美元。拟议的研究将检查真菌疾病Monilinia和Botryis枯萎病对野生蓝莓的结构，功能，生长和发育的影响。 野生蓝莓使用天然存在的甜矮丛（Vaccinium angustifolium）和酸顶（Vaccinium myrtilloides）蓝莓种群进行管理，这些蓝莓含有不同的枝条生长和发育特征，以及对这些疾病的不同抗性水平。 有鉴于此，拟议的研究将努力通过使用无人驾驶飞行器绘制野生蓝莓田间的种群结构，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和发育的影响。这将与研究常规疾病控制产品的交付，沉积，流动性和持久性相配合，并制定降低风险的疾病管理措施，以减少杀菌剂的使用并提高水果质量。研究结果将最终改进预测疾病模型、诊断和疾病控制技术以及生产系统的可持续性。预计该项目将减少30%的农用化学品使用量，降低20%的生产成本。拟议的项目涉及生产者协会和行业赞助商确定的关键研究优先事项，将提高达尔豪西大学的研究能力，并为高素质人才的培训提供一个必不可少的工具。将通过各种平台向该部门的所有生产者和利益攸关方传播研究成果，包括实地考察日、黄昏会议、基于网络的机制，包括野生蓝莓信息网络、科学研讨会和会议以及科学和技术文章。
