摘要
以不同浓度的五氯硝基苯加氧化钙、百菌清、多菌灵等试剂,进行白菜根肿病盆栽防治试验和田间防治试验。结果表明:所选用的药剂均对根肿病有防治效果。其中五氯硝基苯加氧化钙和百菌清处理后的病情指数小,防效也分别达到了66.47%和67.85%,说明2种药剂是延吉市防治白菜根肿病的首选药剂;在产量上五氯硝基苯加氧化钙、百菌清和百菌清加氧化钙处理后的产量最多,产量均达到了10万kg/hm2以上,比对照增产了3.5万kg/hm2以上。
Under different concentration of Pentachloronitrobenzene added calcium oxide, chlorothalonil added to calcium oxide and carbendazol, the control experiments of potted plants and field reveal on Yanji cabbage Clubroot disease was conducted. The results showed that, the medicines both had prevention role. Pentachloronitrobenzene which added to calcium oxide and chlorothalonil least disease index, control effect also reached 66. 47% and 67. 85%, clear description of prevention role.
