Abstract
Mulberry root rot is most severe disease-causing considerable yield loss, caused by fungal pathogen F. solani, which were managed by the use of effective synthetic chemicals. In this view non-systemic, systemic and combi fungicides evaluated by poison food technique against the root rot pathogen, among the novel fungicides evaluated systemic fungicides tebuconazole 25%EC and propiconozole 25% EC were found significantly superior with cent per cent mean mycelial inhibition. Among non-systemic fungicides copper oxy chloride 50% WP was found significantly superior with 96.66 per cent mycelial inhibition at 1000 ppm concentration. Out of six combi products tested metiram 55%WP + Pyraclostrobin 5% WG was significantly effective with maximum mean mycelial inhibition (82.00 %) followed by carbendazim 12 % + mancozeb 63 % WP with 77.11 per cent mean mycelial inhibition. Among these fungicides tested systemic fungicides tebuconozole 25% EC and propiconozole 25% EC has inhibited cent per cent in all three concentrations. Followed by non-systemic fungicide copper oxy chloride with 96.66 per cent inhibition at 1000 ppm respectively.
