【摘要】 [目的]明确腈苯唑与氟啶胺混剂对草莓白粉病和灰霉病的防治作用。[方法]联合毒力试验、田间药效试验。[结果]联合毒力试验结果表明,腈苯唑与氟啶胺混配,在比例为1∶1~1∶5时,对草莓白粉病表现出增效作用;田间试验,混剂(腈苯唑∶氟啶胺=1∶3)在33.75~101.25 g a.i./hm~2剂量下,对草莓白粉病具有良好的防治效果,并且对草莓灰霉病具有很好的兼治作用。[结论]在一些草莓白粉病和灰霉病同时发生的田块,该混剂在33.75~67.5 g a.i./hm~2时,对控制其危害具有十分积极的作用,并且减少农药的施用量。更多还原

【Abstract】 [Aims] This study aims to confirm the efficacy of the mixtures of fenbuconazole and fluazinam against strawberry powdery mildew and gray mould. [Methods] Synergistic action test and field trial wereconducted.[Results] The results indicated that the synergistic effect was afforded by using the mixture of fenbuconazole and fluazinam against strawberry powdery mildew in the range of 1∶1 to 1∶5 in synergistic action test. In field, the mixture of fenbuconazole and fluazinam(the ratio = 1∶3) showed good control against strawberry powdery mildew at the dose of 33.75-101.25 g a.i./ha and an excellent effect on strawberry gray mold as well. [Conclusions] The mixture of fenbuconazole and fluazinam played a very positive role to control the damage of strawberry powdery mildew and gray mould at the dose of 33.75-67.5 g a.i./ha in some fields where these diseases occur at the same time. This technology can reduce the amount of pesticide application.更多还原
