Abstract: Effect of nine tested fungicides on the linear mycelia growth of virulent isolate of Rhizoctonia solani were evaluated in vitro test at concentration 50, 100, 150, 200 and 250 ppm. In vitro, the highest reduction of mycelia growth of R. solani pathogen was found with fungicide Monceren and Chlorothalonil. The fungicide Monceren and Chlorothalonil at concentration of 150 ppm and above showed complete reduction in mycelial growth of R. solani and recorded significantly highest level of hundred per cent growth reduction. These two fungicides were closely followed by Topsin M-70, Bavistin, Benlate, Antracol, Monocut, Boric acid and Matco where total mean per cent growth reductions were 76.75, 63.03, 58.78, 31.79, 51.25, 31.43 and 18.33 respectively.
