Plant-pathogen interactions affected by karanja oil

农业作物需要许多农业投入，包括杀虫剂、生长调节剂、化肥和**其他合成和有机产品。对于有机生产，需要认真评估所有可能的病虫害控制途径，以及效力数据和行动模式。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几种广为人知和**广泛使用的材料，包括细菌和螯合化学品的配方。植物提取物吸引了广泛的兴趣，但产品的一致性和稳定性并没有使它们得到广泛的使用。巨型结缕草(Reynoutria)，其中植物提取物(以Regalia形式提供)已被证明**有助于控制一系列植物上的疾病。植物天然含有广泛的酚类化合物、萜类化合物、黄酮类化合物、植物保鲜蛋白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。在温室里生长。该树种在种子中含有高水平的类黄酮类化合物和酚类化合物。活性制剂的体外毒性将测试对三种病原菌的菌丝生长和孢子萌发的抑制作用。包括重复处理的整个植物实验将评估这些配方是否对植物生长(高度和干重)以及对这两种植物的根(镰刀菌)和叶片(白粉病和灰霉病)的疾病减少**有影响。**研究将调查在处理的植物中诱导的酚类化合物、抗氧化剂和信号分子**的水平是否增加。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洞察力，并促进我们对真菌-植物相互作用的了解，从而导致有价值的**园艺作物的问题疾病的管理，并为有机利用植物提取物进行作物生产提供更多的机会。

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
