| 摘 要： | 两年来用有机汞消石灰混合粉防治馬鈴薯晚疫病的田間試驗获得了显著的效果。在发生中心病株时开始用1:9西力生消石灰或賽力散消石灰每7天撒佈1次,共撒4-5次可以大大地抑制病害的蔓延,从而提高产量。西力生和賽力散的防病效果相近。

| Abstract: | Field experiments have been carried out in the past two years on the control of the potato late blight by dusting with a mixture of organic mercurial and hydrated lime. Started soon after the appearance of disease loci, dusting with the mixture of 1 part Seresan (2% ethyl mercuric chloride) and 9 parts hydrated lime or the same ratio of Ceresan (2.58% phenyl mercuric acetate) and hydrated lime, 5 times at 7 days interval, gave remarkable control of disease and increase in yield. |
