摘要
大豆菌核病又称白腐病，流行年份可减产20％-30％，大豆菌核病是黑龙江省近年来危害大豆的重要病害，发生严重的可达到50％以上，导致百粒重严重下降，造成减产甚至绝产。应用加收米和菌克毒克进行田间防治试验，结果显示加收米和菌克毒克拌种，并在发病前用菌克毒克喷施茎部防治效果较好，防效达69．7％，只用加收米拌种，并在发病前用菌克毒克喷施茎部防治，防效达51．9％，增产13．16％-20．28％。
Soybean white mold is a disease with a general 20% -30% yield reduction and even 50% reduction when it is epidemic. Two agents were tested in field conditions either seed treatment or foliar spraying. The results showed that the control effect reached 69.7% when seed treatment and foliar spraying were integrated, while 51.9% control effect could be obtained if only seed was treated.
