近年来小麦散黑穗病在吉林省病情有所回升,发病率已从1966年前的千分之几上升到1.99％,有的地区发病很重,严重地块达23％,因此防治小麦散黑穗病已是生产上迫切要求解决的问题。对防治小麦散黑穗病国内外多采用萎锈灵、多菌灵等药剂,但防效不够理想。近来国内用拌种双防效较好,但使用浓度用0.3％就有一定药害,因而应当找出有效而又安全的药剂。为此我们在1980～1982年对禾穗胺等几种农药在防效、种子处理方法、贮藏后的增效作用进行了试验,结果如下。
In recent years, the incidence of wheat smut in Jilin Province has risen somewhat. The incidence has risen from a few thousandths before 1966 to 1.99%. In some areas, the incidence of severe smut is as high as 23%. Therefore, Smut is an issue that is urgently required to be solved in production. The prevention and treatment of wheat scattered smut at home and abroad to use more rust Ling, carbendazim and other agents, but the control effect is not ideal. Recently, the domestic use of seed dressing double control effect is better, but the use of concentration of 0.3% there is a certain phytotoxicity, and therefore should find effective and safe agents. To this end, we conducted experiments on the synergistic effects of several pesticides such as arachidic between control effect, seed treatment method and storage after 1980-1982. The results are as follows.
