澳大利亚科学家日前探索到了在澳洲生长的植物中,广泛存在良性的天然物质。这些物质能够抵制植物疾病,从而可以在粮食作物中减少使用化学药剂。热带植物病理学合作研究中心的一个小组逐一研究了250多种澳洲植物,现已证明其中至少有20种天然复合物在防治水果和粮食作物的主要真菌疾病方面很有希望。研究中心副所长、联邦科学与工业组织的农业专家约翰·曼纳斯博士说:“这些复合物中,有些在防治真菌疾病中能起抗 Australian scientists have explored the widespread presence of benign natural substances in plants growing in Australia. These substances counteract plant diseases and therefore reduce the use of chemicals in food crops. A team of Tropical Plant Pathology Collaborating Research Centers studied more than 250 species of Australian plants one by one and at least 20 of them have proven promising for the control of major fungal diseases in fruits and food crops. Dr. John Manus, Deputy Director of the Center for Agricultural Science at the Federal Science and Industry Organization, said: ”Some of these compounds are active against fungal diseases
