第22卷第4期2023年8月现代农药ModernAgrochemicalsVol.22No.4Aug.2023·药效与应用?桶混助剂对25%吡唑醚菌酯悬浮剂防治黄瓜靶斑病的调控作用曹雄飞1*,刘变娥1,孟令涛²,王佳辉2(1.江苏擎宇化工科技有限公司，扬州211400;2.山东滨农科技有限公司，滨州256600)摘要：为了明确桶混助剂对吡唑醚菌酯防治黄瓜靶斑病的调控作用，本研究结合助剂的结构特点，探究了SP-4806、SY-A、SY-B、SY-C等4种桶混助剂对25%吡唑醚菌酯悬浮剂对靶沉积界面性能、黄瓜体内吸收传导性能以及对黄瓜靶斑病防效的影响。试验结果表明，4种助剂均能降低表面张力、接触角，增强润湿渗透性能，促进25%吡唑醚菌酯悬浮剂在黄瓜体内向上传导作用，且助剂SP-4806对25%吡唑醚菌酯悬浮剂在黄瓜体内向下传导具有显著促进作用。4种桶混助剂均不同程度促进25%吡唑醚菌酯悬浮剂对黄瓜靶斑病的防效，其中添加助剂SP-4806处理的防效较25%吡唑醚菌酯悬浮剂显著提高，药后9d防效分别为76.76%。本研究结果可为桶混助剂对25%吡唑醚菌酯悬浮剂应用于防治黄瓜靶斑病提供参考。关键词：助剂；吡唑醚菌酯；吸收传导；黄瓜靶斑病；防效中图分类号：TQ455TheSynergisticEffectofTank-mixingAdjuvantson25%PyraclostrobinSC(1.JiangsuSinvoChemS&TCo.,Ltd.,Yangzhou211400,China;2.ShandongBinnongTechnologyCo.,Ltd.,Binzhou256600,China)Abstract:Inordertoclarifythesynergisticeffectofadjuvantsonpyraclostrobin25%SCagainstcucumbertargetspot,thisstudyinvestigatedtheeffectsoffourtank-mixingadjuvants,SP-4806,SY-A,SY-B,andSY-Conthetargetdepositioninterfaceperformance,invivoabsorptionandtransmissionperformance,andpreventionandcontrolofcucumbertargetspotdiseaseofpyraclostrobin25%SC,basedonthestructuralcharacteristicsoftheadditives.Theexperimentalresultsshowedthatallfouradjuvantscouldreducesurfacetension,contactangle,enhancewettingandpermeability,andpromotetheupwardconductionofpyraclostrobin25%SCincucumber.Additionally,theadjuvantSP-4806hadasignificantpromotingeffectonthedownwardconductionofpyraclostrobin25%SCincucumber.Fourtypesofbucketmixedadditivesallpromotedthecontroleffectofpyraclostrobin25%SConcucumbertargetspotdiseasetovaryingdegrees.Amongthem,thetreatmentwithadditivesSP-4806significantlyimprovedthecontroleffectcomparedt...
