植物猝死病是一种侵染棉花、豆类、蔬菜等多种作物的常见病害,在美国每年为防治此病需耗资10亿美元。最近,美国科学家改进了一种叫做Gliocladium virens的有益真菌。这种改造的真菌不但能有效地防治植物猝死病,而且能抗一般的化学杀菌剂,将来农民可以同时使用两种药剂控制作物的土传病害。 Sudden death from plant disease is a common disease that infects cotton, beans, vegetables and other crops and costs about $ 1 billion a year in the United States to prevent and treat the disease. Recently, U.S. scientists have improved a beneficial fungus called Gliocladium virens. This modified fungus not only can effectively prevent sudden death from plant diseases, but also can resist common chemical fungicides. In the future, farmers can use two kinds of medicaments to control soil-borne diseases of crops.
