英国一组科学家研究了从烟叶分泌出来的杀霉剂以防治作物病害,一种野生烟草(Nicotiana Intinosa)的烟叶上分泌出有两种已经分离检定的化学物质,它们能在不损害作物情况下有效地抑制锈病霉菌。当豆类或小麦植株喷布了0.01％这些化合物几乎可以完全免染锈病。农业研究委员会还报告说,这一方面自然存在的植株抗生素分离 A group of British scientists studied the fungicide secreted from tobacco leaf to prevent crop disease. The tobacco of one Nicotiana species (Nicotiana Intinosa) secrete two chemical substances that have been separated and tested. They can be used without damage to crops Effectively inhibit rust mold. When beans or wheat plants are sprayed with 0.01% these compounds are almost completely free of rust. The Agricultural Research Council also reported that the naturally occurring plant antibiotics in this area were separated
