Effect of some systemic and protectant fungicides on growth of Verticillium albo-atrum, Rhizobium meliloti and lucerne seedlings in the laboratory


, : Effect of some systemic and protectant fungicides on growth of Verticillium albo-atrum, Rhizobium meliloti and lucerne seedlings in the laboratory. Protection Ecology 6(4): 279-286

The effect of six systemic and six non-systemic fungicides on the growth of seven Verticillium albo-atrum isolates on PDA was examined at 1 and 10 mu g a.i./ml. With the exception of phosethyl aluminium, the systemics inhibited growth, the inhibition being complete at 10 mu g benomyl or ectaconazole. At the concentrations tested, protectant fungicides had a very limited efficacy on all isolates.
