Effect of fungicides to control purple stain of soybean [Glycine max. (L.) Merill] caused by Cercospora kikuchii

The investigations were carried out to find out effect different fungicides to control purple stain of soybean caused by Cercospora kikuchii. Among all the fungicidal treatments carbendazim @ 0.2%, copper oxychloride @ 0.25%, thiram + carbendazim @ 0.3% (1:1 ratio), thiram @ 0.2% and propiconazole @ 0.05% were significantly superior over control and rest of fungicidal treatments in controlling purple stain of soybean. Among all the fungicides carbendazim @ 0.2% showed highest per cent disease control i. e. 93.34%. It was followed by copper oxychlorides @ 0.25% (90.88%), thiram + carbendazim @ 0.3% (88.48%), thiram @ 0.2% (88.00%) and propiconazole @ 0.05% (87.36%).
