Improving plant biostimulants based on natural products and beneficial microorganisms

植物生物刺激剂被定义为生物来源的物质或活微生物，或两者兼而有之，其作用应用于植物或土壤时，刺激生物过程，改善宏观和微量营养素的动员和吸收；缓解非生物应激；保护植物免受病原体和害虫的侵害。BioSun和Lumiera是两家新兴企业，它们积极参与开发用于制造生物刺激素的天然衍生产品。Biosun开发和销售天然产品，如生物农药和生物刺激素。Lumiera参与天然保健产品的开发和商业化。这个行业驱动的项目旨在解决BioSun和Lumeria进入生物刺激素市场的问题。该项目的目标是：优化工厂的生产过程；开发改进的第二代CELEXT07生物防治；并通过适当的控制，在田间试验中验证改良产品的农艺性能。该应用研究项目的成果是优化Plantiful的生产工艺并开发第二代CELEXT07。有了这两种产品，我们预计大田作物和蔬菜的产量至少会增加20%。例如，西红柿产量增加20%，每公顷将使加拿大农民的价值增加2万美元。我们还希望通过控制葡萄孢菌和白粉病等病原体的攻击来减少作物损失。该项目将立即使BioSun和Lumiera从改良产品的商业化中受益，并使作物生产商从提高农场盈利能力中受益。在高投入农业系统中，生物刺激剂已证明其有效性，可减少化学品投入的使用。该项目将有助于确保加拿大农场未来的盈利能力。它将进一步提高加拿大农业食品工业在创新和环境管理方面的世界领先地位。此外，该项目将对加拿大在气候变化和人口增长的情况下改善粮食安全的总体努力作出重大贡献。

Plant biostimulants are defined as either substances of biological origin or living microorganisms or both whose functions, when applied to plants or soils, stimulate biological processes that improve the mobilization and uptake of macro- and micro-nutrients; alleviate abiotic stress; and protect plants against pathogen and pest attacks. BioSun and Lumiera are two emerging businesses that are actively involved in the development of natural-derived products to manufacture biostimulants. Biosun develops and markets natural products such as biopesticides and biostimulants. Lumiera is involved in the development and commercialization of natural health products. This industry-driven project was designed to solve BioSun and Lumeria issues to enter into biostimulant market. The objectives of this project are: to optimize the Plantiful production process; to develop an improved second generation of CELEXT07 biocontrol; and to validate the agronomic performance of improved products in field trials with appropriate controls.The outcomes of this applied research project are to optimize the production process of Plantiful and to develop a second generation of CELEXT07. With these two products, we expect to increase yield of field crops and vegetables by at least 20%. As an example, increasing tomatoes yield by 20% would increase the value of Canadian farmer by $20 000 per hectare. We also expect to reduce crop loss by controlling pathogen attacks such those of Botrytis cineria and powdery mildew.This project will immediately benefit BioSun and Lumiera from commercialization of improved products, and crop producers from improved farm profitability. In high-input agrosystems, biostimulants have proven their effectiveness, allowing a reduction in chemical input use. This project will contribute to securing Canadian farm profitability into the future. It will further the reputation of Canada's agri-food industry as a world leader in innovation and environmental stewardship. Moreover, this project will make substantial contributions to Canada's overall efforts to improve food security in the face of a changing climate and growing population.
