一个国际科研小组在新一期美国《国家科学院学报》网络版上报告说,他们发现,某些植物原料含有一种酸性物质,其杀菌能力约为常用农药的10倍。研究人员表示,未来有望据此开发出新型农药,从而减少对环境的影响。感染病原菌可能导致农作物大幅减产,而长期使用化学农药则会加重环境负担,不利于土壤的可持续生产。日本东京大学研究生院、理化学研究所的科研人员与美国威斯康星大学 An international team of researchers reported in a new issue of the Proceedings of the National Academy of Sciences online that they found that some plant materials contain an acidic substance and have a bactericidal capacity about 10 times that of commonly used pesticides. Researchers said the future is expected to develop a new type of pesticide, thus reducing the environmental impact. Infection with pathogens can lead to a sharp reduction in crops, while long-term use of chemical pesticides can add to the burden on the environment and is not conducive to the sustainable production of soils.
