Screening of Fungicides, Botanicals and Bioagents against Colletotrichum dematium In Vitro

Rajkumar Kothikar

Abstract


Turmeric is an important and economical medicinal and aromatic crop. It is subjected to variety of diseases like leaf spot, leaf blotch, leaf blight, rhizome rot etc. which are threat in turmeric production. Among these diseases, leaf spot caused by Colletotrichum dematium is important and major limiting factor for yield loss. Realizing the potentiality of the disease in causing economic losses, the different fungicides (propiconazole, mancozeb, carbendazim, hexaconazole, penconazole), botanicals (Azadirachta indica, Agael marmalos, Eucalyptus sp.) and bio-agents (Trichoderma viride, Trichoderma harzianum) were screened against Colletotricum dematium in vitro. In vitro studies by poisoned food technique revealed that, fungicide propiconazole 0.1% found to be most effective among all the chemicals, botanicals and bioagents and gave 91.98% mycelia inhibition of C. dematium. Among the botanicals, Azadirachta indica seed extract 5% (74.69%) found to be superior. Dual culture studies of antagonism reported that, the bio-agent Trichoderma viride (80.11%) was found most effective against C. dematium.
