谷子白发病是我国谷子生产上的重要病害,一般发病率在2—5%,严重的达20—40%。以前曾推广过温汤浸种、药剂拌种和拔除白尖病株等方法进行防治,但因病菌可通过土壤感染,效果不大。而品种间抗病能力在不同地区表现也有差异,有必要进一步了解不同地区间品种抗病性的变化,以便提供抗源材料,较好地控制其病害的发生与为害。1980年我所开始谷子品种抗病性鉴定,1981
Mildew white hair is an important disease in China’s millet production, the general incidence of 2-5%, severe up to 20-40%. In the past, it had been promoted to prevent and cure the soaking of Wen Tang, drug seed dressing and white-tip diseased removal. However, the bacteria can not pass the soil infection and have little effect. However, there is a difference in disease resistance among different varieties in different regions. It is necessary to know more about the change of disease resistance in different regions in order to provide anti-source materials and better control the occurrence and damage of their diseases. In 1980 I started the millet variety disease resistance identification, 1981
