助剂对异菌脲防治烟草灰霉病的增效作用研究
|
摘要
为明确助剂对异菌脲生物活性的影响,采用室内生物活性测定法研究了6种助剂对异菌脲防治烟草灰霉病的增效作用及对药液物理性状的影响。结果表明,供试的6种助剂对异菌脲均有不同程度的增效作用,有机硅助剂的增效作用大于植物油助剂,不同有机硅助剂的增效作用也存在差异。有机硅助剂显著降低了异菌脲药液的表面张力,增大了药液的扩展直径,增加了药液在烟草叶面的持留量。
In order to clear the effects of adjuvants on iprodione, the synergism of six adjuvants on iprodione in controlling Botrytis cinerea and the changes of physical properties of the solution were determined by means of bioassay in laboratory. The results showed that the tested six adjuvants all increased the control efficacies of iprodione on Botrytis cinerea. The synergism effects of organosilicon adjuvants were better than that of plant oil adjuvant. And different organosilicon adjuvants had different control efficacy. The organosilicon adjuvants reduced evidently surface tension of iprodione, improved spreading diameter and increased the leaf retention.
