一项最新研究结果表明,北京地区番茄灰霉病菌对嘧霉胺的抗药性已经非常普遍。为了检测北京地区番茄灰霉病菌对嘧霉胺的抗药性,指导生产上科学用药,研究人员从北京12个区县采集番茄灰霉病样150份,分离纯化获得109个番茄灰霉病菌的单孢菌株,采用菌丝生长速率法测定了番茄灰霉病菌对嘧霉胺的抗
A new study shows that the resistance of Botrytis cinerea to pyrimethanil in Beijing is very common. In order to detect the resistance of Botrytis cinerea to pyrimethanil in Beijing and to guide the production of scientific medication, the researchers collected 150 samples of Botrytis cinerea from 12 districts and counties in Beijing, and isolated and purified 109 Spore strains were used to determine the resistance of Botrytis cinerea to pyrimethanil by mycelial growth rate method
