防治烟草赤星病药效试验

Experiments on Control Effects of Tobacco Alternaria alternata with Chemicals

摘要: 为了更有效地防治烟草赤星病,用7种药剂进行了大田喷施对比试验。结果表明:40%"菌核净"可湿性粉剂500倍液、40%"菌核铜"可湿性粉剂500倍液、45%"菌克"可湿性粉剂500倍液、"云岭酶素"300倍液、45%"金叶舒"可湿性粉剂600倍液、3%"多抗霉素"可湿性粉剂300倍液、30%"大力"可湿性粉剂500倍液的相对防效依次为:92.56%、92.13%、92.13%、91.18%、90.36%、87.56%、85.02%、83.91%,差异达显著水平。

Abstract: For controlling tobacco Alternaria alternata more effectively, the field contrast experiments of 7 kinds of chemicals were conducted.The results showed that the relative control effects of 40% Dimethachlon WP at a dilution of 500, 40% Dimethachlon and Copper WP at a dilution of 500, 45% Junke WP at a dilution of 500, Yunlingmeisu at a dilution of 300, 45% Jinyeshu WP at a dilution of 600, 3% Polyoxins WP at a dilution of 300 and 30% Dali WP at a dilution of 500 were 92.56%, 92.13%, 91.18%, 90.36%, 87.56%, 85.02% and 83.91%, respectively.There were significant differences among the control effects of the chemicals.
