An experiment was carried out to find out the in-vitro efficacy of systemic and contact fungicides against the pathogen of maize banded leaf and sheath blight (Rhizoctonia solani f. sp. sasakii) by using poisoned food technique. The present experiment was conducted in College of Post Graduate Studies in Agricultural Sciences, Central Agricultural University, Umiam, Meghalaya for the evaluation of different fungicides against the pathogen R. solani f. sp. sasakii. Eight systemic (Carbendazim, Tebuconazole, Propiconazole, Myclobutanil, Azoxystrobin, Metalaxyl, Tricyclazole, Pyraclostrobin), three contact (Mancozeb, Captan and Chlorothalonil) and combination of systemic and contact fungicide (Carbendazim + Mancozeb) were used for the experiment with different concentrations. Among twelve fungicides, Carbendazim was found to be the most effective at concentration of 0.1 % with 95.96 % growth inhibition. Suimilarly, Metalaxyl at concentration of 0.28 % was found to be the least effective with growth inhibition of 55.55 %. The results showed significant differences between different fungicides to inhibit the growth of R. solani.
