In vitro evaluation of the fungicides, botanicals and bioagents against Colletotrichum truncatum causing anthracnose of soybean

Abstract

Soybean (Glycine max (L.) Merill) is one of the world’s most important oilseed cum legume crop. The present present research work was conducted at Plant Pathology Section, College of Agriculture, Dhule during 2012-2013. The result revealed that treatments carbendazim @0.1%, Tebuconazole @0.1% and Propiconazole @0.1% were found significantly superior over rest of the treatments, which recorded maximum growth inhibition of 97.67%, 97.67% and 97.28%, respectively of the test pathogen with minimum colony diameter of 2.10 mm, 2.10 mm and 2.45 mm, respectively, all were at par with each other. In case of bioagents and botanicals Pseudomonas fluorescens (89.11%), Trichoderma harzianum (88.00%), Propineb (87.00%), Neem (84.72%), Chlorothalonil (81.94%) and Copper oxychloride (78.56%), which were recorded mean colony diameter of 9.80 mm, 10.80 mm, 11.70 mm, 13.75 mm,16.25 mm and 19.30 mm, respectively. While, Thiophanate methyl (75.28%), Ziram (66.39%) and Eucalyptus (55.22%) showed least growth inhibition of the test pathogen with mean colony diameter of 22.25 mm, 30.25 mm and 40.30 mm, respectively.
