高粱是我县主要粮谷作物之一,播种面积历年都占60%左右。多年来,由于种植面积大,品种单一,不能合理的轮作倒茬,致使高粱丝黑穗病发病程度逐年加重。从1977年起全县每年平均发病率都在10%以上,有的年份个别地块发病率竟高达80%以上,严重威胁我县高粱生产。二年来,我们大面积使用了禾穗胺防治高粱丝黑穗病,取得了明显效果。1982年又进行了不同药剂、筛选试验示范工作。现将结果汇总如下:一、药剂及来源1.50%禾穗胺粉剂(沈阳化工研究院生产并提供)
Sorghum is one of the main grains and cereals in our county. The sown area accounts for 60% of the total. Over the years, due to large acreage, a single species, can not be reasonable rotation cropping, resulting in morbidity of sorghum smut increased year by year. Since 1977, the average annual incidence of the county are more than 10%, some of the individual block as high as 80% incidence, a serious threat to my county sorghum production. In the past two years, we have used oxaliplatin to control sorghum smut over a large area and achieved remarkable results. In 1982 and conducted a different pharmaceutical, screening and demonstration work. The results are summarized below: First, the pharmaceutical and sources 1.50% Wo ear powder (Shenyang Chemical Research Institute to produce and provide)
