我地区小麦散黑穗病一般发病2%左右,有些易感品种如垦149发病率高达6—7%,又因近几年小麦开花期雨水适宜,病穗有逐年增加的趋势。过去防治小麦散黑穗病较有效的办法是温汤浸种或石灰水浸种,1974年我场试验站温汤浸种处理300亩垦149小麦,比未浸的黑穗病减少90%,但此法要求条件较严格,作业麻烦,不适宜大量处理种子,生产实践中应用不广。 1980年我场13连在6,360亩小麦上用多菌灵湿拌闷种的方法防治小麦散黑穗病,收到了较好效果,
In our region, the average incidence of smut is about 2%. Some susceptible cultivars, such as Ken-149, have a high incidence of 6-7%. In recent years, the flowering period of wheat is suitable for rainwater, and the disease panicle tends to increase year by year. In the past, the method of preventing and treating wheat smut was more effective than soaking seeds with warm soup or lime soaking. In 1974, we immersed 300 mu of cultivated 300 149 wheat in Wen Wen Tang of our field test station, which was 90% less than that of uns smoked smut. However, More stringent, operational problems, not suitable for large-scale processing of seeds, the production practice is not widely used. In 1980, my field 13 with 6,360 acres of wheat on the use of carbendazim wet mixed boring kind of prevention and control of wheat scattered smut, received a good effect,
