Agricultural crop plants require many agricultural inputs, including pesticides, growth regulators, fertilizers and**other synthetic and organic products. For organic production, a careful assessment of all possible avenues for**pest and disease control, and efficacy data and modes of action, need to be well studied. Sources of**organically-certified products for disease control in Canada are currently limited to a few well-known and**widely used materials that include formulations of bacteria and chelated chemicals. Plant extracts have**attracted wide interest but the consistency and stability of the product has not enabled their widespread use.**There are a few examples eg. giant knotweed (Reynoutria) where plant extracts (available as Regalia) have**been shown to be useful for managing diseases on a range of plants . Plants naturally contain a wide range of**phenolic compounds, terpenoids, flavonoids, phytoalexins and other chemicals that have potential antifungal**properties. In this research, formulated extracts derived from the Karanj tree (Pongamia pinnata) will be tested**for management of three important fungal pathogens that infect greenhouse cucumber plants and medical**cannabis (Cannabis sativa L.) grown in greenhouses. This tree species contains high levels of flavonoids and**phenolic compounds in seeds. The in vitro toxicity of Activate formulations will be tested against mycelial**growth and spore germination of the three pathogens. Whole plant experiments that include replicated**treatments will evaluate whether the formulations have effects on plant growth (height and dry weight) as well**as disease reduction on roots (Fusarium) and leaves (powdery mildew and Botrytis) of the two plant species.**The research will investigate whether induced levels of phenolic compounds, antioxidants and signalling**molecules such as jasmonic acid and salicylic acid, are increased in treated plants. The results will provide**additional insight into the mechanisms of how these plant-derived products affect plant growth and advance**our knowledge on fungal-plant interactions, leading to management of problematic diseases on valuable**horticultural crops and provide additional opportunities for organic uses of plant extracts for crop production

农作物种植需要许多农业投入，包括杀虫剂、生长调节剂、肥料和其他合成和有机产品。就有机生产而言，需要认真研究对病虫害控制的所有可能途径、有效性数据和行动方式进行仔细评估。在加拿大，用于疾病控制的 ** 有机认证产品的来源目前仅限于一些众所周知和 ** 广泛使用的材料，包括细菌和螯合化学品的配方。植物提取物 ** 引起了广泛的兴趣，但产品的一致性和稳定性使其无法广泛使用。有几个例子，例如。巨大的虎杖（虎杖），其中植物提取物（可作为Regalia获得）已被证明可用于管理一系列植物上的疾病。植物天然含有大量的酚类化合物、萜类化合物、类黄酮、植物抗毒素和其他具有潜在抗真菌特性的化学物质。在这项研究中，来自Karanj树（Pongamia pinnata）的配方提取物将被测试 ** 用于管理感染温室黄瓜植物和医用 ** 大麻（Cannabis sativa L.）的三种重要真菌病原体。生长在温室里。该树种种子中含有高水平的黄酮类化合物和 ** 酚类化合物。将针对三种病原体的菌丝体 ** 生长和孢子萌发测试Activate制剂的体外毒性。包括重复 ** 处理的全植物实验将评估制剂是否对两种植物物种的植物生长（高度和干重）以及 ** 对根（镰刀菌属）和叶（白粉病和葡萄孢属）上的疾病减少具有影响。这项研究将调查在处理过的植物中，酚类化合物、抗氧化剂和信号分子（如茉莉酸和水杨酸）的诱导水平是否增加。这些结果将为这些植物衍生产品如何影响植物生长的机制提供更多的见解，并推进我们对真菌-植物相互作用的了解，从而管理有价值的园艺作物上的疑难疾病，并为植物提取物在作物生产中的有机用途提供更多机会。
