75％肟菌酯·戊唑醇水分散粒剂防治香蕉黑星病的应用效果

摘要

75% trifloxystrobin o tebuconazole WG is an efficient fungicide and up-to-date product from Bayer CropScience, Germany. The results of control effect tests of 75% trifloxystrobin o tebuconazole WG in fields in 2010 and 2011 showed that application of this fungicide (1:2 500) for 4 times gave a control effect of 75.13% - 78. 73% against banana freckle disease. These results demonstrated that 75% trifloxystrobin·tebuconazole WG had a better control effect against banana freckle disease than 430 g/L tebuconazole SC (1: 000) , 50% trifloxystrobin WG (1:5 000) and 250 g/L difenoconazole EC (1:1 500), and it was worthy to be popularized in banana orchards.%肟菌酯·戊唑醇混配剂是德国拜耳作物科学公司近年开发的新杀菌剂,2010-2011年进行了该药剂对香蕉黑星病的防治效果试验.两年的试验结果表明,75％肟菌酯·戊唑醇水分散粒剂是防治香蕉黑星病的优良杀菌剂,2 500倍液施药4次对香蕉黑星病防治效果达到75.13％～78.73％,优于3个对照药剂430 g/L戊唑醇悬浮剂2000倍液、50％肟菌酯水分散粒剂5000倍液及250 g/L苯醚甲环唑乳油1500倍液施药4次后的防效,值得在香蕉产区推广应用.
