赤斑病是对蚕豆产量影响最大的病害,广泛发生于我国各种植区。近年来,由于气候异常等因素,其危害愈发严重。就目前科技发展水平来看,药剂防治仍然是最直接、最有效的防治办法。但截至2017年8月底,尚未有专门防治蚕豆赤斑病的药剂在我国获批登记。南京农业大学研究人员以新发现的能引起蚕豆赤斑病的病原菌之一的拟蚕豆葡萄孢为对象,使用7种杀菌剂对其进行室内药效试验,用生长速率法进行7种农药的抑制效果进行对比,再
Red spot is the disease that has the most impact on the yield of broad bean, which occurs widely in all kinds of planting areas in China. In recent years, due to climate anomalies and other factors, the harm is more serious. At present, the level of scientific and technological development point of view, pharmaceutical control is still the most direct and effective prevention and treatment measures. However, as of the end of August 2017, no pesticide has been approved for the control of broad bean red spot in China. Researchers from Nanjing Agricultural University, using the newly discovered fungus Botrytis cinerea, one of the pathogenic bacteria causing broadleaf red spot, were tested for indoor efficacy using seven fungicides and seven kinds of pesticides were inhibited by the growth rate method The effect of contrast, and then
