运用生物防治菌治疗农作物病害成为许多国家研究的重点,但因防治菌要求土壤环境不能受到化学农药的污染而无法被应用到农业生产中。日前,哈工大理学院生命科学与工程系教授杨谦运用转基因方法,成功研制出第二代毛壳菌生物防治菌产品,具有了对抗化学农药的抗药性。该项技术填补了国际空白。植物病原菌的抗药性是植物病害化学防治中的一个严重问题,它给多种植物病害的防治带来很大障碍。因为抗药性引起了防治效果下降,甚至完全失效而造成了很
The use of biological control bacteria to treat crop diseases has become the focus of research in many countries. However, the control of bacteria requires that the soil environment can not be contaminated with chemical pesticides and can not be applied to agricultural production. Recently, Yang Hg, a professor of life science and engineering at HIT Dali University, successfully developed the second-generation Chaetomium biological control bacterial product by using the transgenic method and has the resistance to chemical pesticides. The technology fills the international void. The resistance of plant pathogens is a serious problem in the chemical control of plant diseases, which brings great obstacles to the prevention and control of many plant diseases. Because of resistance caused by the prevention and control of the decline, or even completely invalidated caused very
