赤斑病是蚕豆的主要病害。三、四月份蚕豆开花结荚期间,阴雨连绵,田间湿度大,有利赤斑病菌传播蔓延,使蚕豆“未老先衰”,提早落叶、死秆。常年因该病为害,减产二成左右,重病年份减产四至五成。为了控制蚕豆赤斑病的发生,我们使用内吸性菌剂——多菌灵、托布津进行防治试验,取得了显著的防病和增产效果。 Red spot is the main disease of broad beans. In April and April, during the flowering and podding of broad beans, the rainy and rainy days led to the spread of R. solanacearum in the fields, making the broad bean “not old and decaying” and early deciduous and dead stalk. Perennial disease due to the disease, cut about two percent, serious illness year cut four to five into. In order to control the occurrence of broad bean red spot, we use systemic fungicides - carbendazim, Topaz for control trials, and achieved significant disease prevention and yield increase.
