为探明啶酰菌胺与氟啶胺复配物对水稻纹枯病菌和草莓灰霉病菌的增效潜力,采用菌丝生长速率法测定啶酰菌胺和氟啶胺复配物对水稻纹枯病菌和草莓灰霉病菌的抑制效果,并根据Wadley方法评价复配物增效作用。结果表明:啶酰菌胺和氟啶胺对水稻纹枯病菌均具有抑制作用,其EC_(50)分别为0.483 6 μg/mL和0.054 1 μg/mL。将啶酰菌胺和氟啶胺按照1∶5、1∶4、1∶3、1∶2、1∶1、2∶3、3∶2、5∶1、4∶1、3∶1和2∶1的比例进行复配,结果表明:按照1∶2、3∶2、5∶1、4∶1、3∶1和2∶1复配对水稻纹枯病菌均具有增效作用,其中以3∶1和3∶2比例复配增效最佳,增效系数分别为7.7和5.46;以1∶1、1∶3、1∶4、1∶5和...

In order to clarify the synergism of boscalid and fluazinam against Rhizoctonia solani and Botrytis cinerea, the inhibition effects of boscalid-fluazinam mixtures to R.solani and B.cinerea were investigated by mycelial growth rate test. The results showed that they both have notable inhibition effects against R.solani and B.cinerea, with the EC_(50)values of 0.483 6 μg/mL and 0.054 1 μg/mL, respectively. The mixtures of of boscalid and fluazinam at the ratio of 1∶2, 3∶2, 5∶1, 4∶1, 3∶1 and 2∶1 had synergism to R.solani. The mixtures at t...
