防治烟草黑胫病的药效试验

Control Effect Experiment of Pesticide Against Tobacco Black Shank

测定了"百抗"、"东旺黑达"、活性菌肥、"金雷多米尔"、"安克"、"宝大森"、58%"甲霜灵锰锌"、72%"甲霜灵锰锌"等药剂对烟草黑胫病的防治效果。结果表明,"东旺黑达"、"宝大森"、"58%甲霜灵锰锌"、"活性菌肥"、72%"甲霜灵锰锌"、"安克"对烟草黑胫病的防效均较好。其中,"东旺黑达"的防效最好,在病害盛发期的相对防效达到67.48%,生物农药"百抗"和"活性菌肥"防效也分别达到62.71%和65.11%。

The control effects of eight pesticides,including Bacillus subtilis B908 WP,48% cuaminosulfate propamocarb AS,active microorganism fertilizers,53% methalaxyl-mancozeb WG,50% dimethomorph WP, 58% metalaxyl mancozeb WP （ Baodasen） ,58% metalaxyl mancozeb and 72% metalaxyl mancozeb,against tobacco black shank were studied. The results showed that the control effects of 48% cuaminosulfate propamo- carb AS,58% metalaxyl mancozeb WP （ Baodasen） ,58% metalaxyl mancozeb WP,active microorganism fertilizers,72% metalaxyl mancozeb and 50% dimethomorph WP were good,particularly 48% cuaminosulfate propamocarb AS,whose relative control effect reached 67. 48% at full incidence period. The relative control effects of the two biological pesticides,Bacillus subtilis B908 and active microorganism fertilizers,were up to 62. 71% and 65. 11% ,respectively.
