Three fungicides, namely Bavistin 50 WP (Carbendazim),
Ridomil (Metalaxyl) and Provax-200 (Carboxin),
were tested in vitro to evaluate their effect on colony
growth and sclerotia formation of R. solani following
the poison food technique on PDA Petri plates [19]. All
fungicides were used at 100, 250, and 500 ppm. The details
of the fungicides are presented in Table 1.
