Over the next few decades we must increase both agricultural productivity, to deal with growing populations and fuel supply, and agricultural sustainability. Biological inputs are one way to achieve this. Seaweeds have been exploited as producers of biostimulants, and within Canada, Ascophyllum nodosum has been developed into commercial products sold around the world. The proposed work will lead to a broad understanding of the ability of a set of seaweed extracts and formulations to provide biocontrol measures against fungal pathogens of key crop plants of eastern Canada. We will evaluate the effects of selected seaweed extracts and formulations of these for ability to diminish the growth of fungal pathogens, and also for the enhancement of plant growth promotion. Data will be collected on aspects of fungal growth and development under Petri plate conditions and in the presence of specific seaweed extracts and formulations, with a view to identifying those with greatest efficacy. In addition, the materials with greatest antifungal activity (combination of extract and formulation) will be evaluated for plant growth promotion and effects on specific aspects of crop physiology. Acadian Seaplants has conducted preliminary research regarding the seaweed extracts and will provide the most interesting types for the proposed work. The evaluation crop used in this research will be tomato, as it is a high value crop produced extensively in eastern Canada. The work will be conducted through a collaboration between Acadian Seaplants and the Smith laboratory research team at McGill University, in order to elaborate and implement their processes and understandings to date. The work regarding anti-fungal and growth stimulation capability of the seaweed-derived materials will provide a better understanding of the applicability of their current product, and with new products and the foundations for even further products, establishing it as a leader in the rapidly expanding biologicals sector. This will also enhance the sustainability and economics of Canadian agricultural, giving Canada further leadership in the agricultural application of biologicals.

在接下来的几十年里，我们必须提高农业生产力，以应对不断增长的人口和燃料供应，并提高农业的可持续性。生物输入是实现这一目标的一种方式。海藻已被开发为生物刺激素的生产者，在加拿大，Ascophyllum nodosum已被开发成商业产品，销往世界各地。这项工作将导致对一系列海藻提取物和配方的能力的广泛理解，为加拿大东部主要作物的真菌病原体提供生物防治措施。我们将评估选定的海藻提取物及其配方的效果，以减少真菌病原体的生长，并加强植物的生长促进。将收集关于真菌在培养皿条件下和在特定海藻提取物和配方存在的情况下生长和发育方面的数据，以期确定那些最有效的数据。此外，将评估具有最大抗真菌活性的材料（提取物和制剂的组合）对植物生长的促进作用和对作物生理特定方面的影响。Acadian Seaplants已经对海藻提取物进行了初步研究，并将为拟议的工作提供最有趣的类型。本研究中使用的评价作物将是番茄，因为它是加拿大东部广泛生产的高价值作物。这项工作将由Acadian Seaplants和McGill大学的Smith实验室研究团队合作进行，以详细阐述和实施他们迄今为止的流程和理解。关于海藻衍生材料的抗真菌和生长刺激能力的工作将更好地了解其当前产品的适用性，以及新产品和进一步产品的基础，使其成为快速扩张的生物制品领域的领导者。这也将提高加拿大农业的可持续性和经济性，使加拿大在生物制品的农业应用方面进一步发挥领导作用。
