Bio-efficacy of triticonazole 8%+pyraclostrobin 4% FS, pyraclostrobin 20% FS,triticonazole 2.5 % against loose smut of wheat

The field trials were conducted to evaluate the bio efficacy of new fungicide Triticonazole 8%+ Pyraclostrobin 4% FS (Insure Perform 12% FS) @ 0.50, 0.75 and 1.00 ml per kg of seed against loose smut of wheat (Triticumaestivum) caused by Ustilagotriticiby taking infected seeds during 2011-12 and 2012-13 crop seasons at Karnal, India in comparison with recommended fungicide Tebuconazole 2% DS. The test fungicide,Triticonazole 8%+ Pyraclostrobin 4% FS (Insure Perform 12% FS) was highly effective in controlling the disease and gave more than 95% control that was at par with Tebuconazole @ 1.0 g perkg of seed. It may therefore be used as an alternative to already recommended fungicides for the management of loose smut of wheat.
