Co-inoculation timing affects the interspecific interactions between phoma stem canker pathogens Leptosphaeria maculans and L. biglobosa.

For the first time, the results of this study provided evidence that the timing when L. maculans and L. biglobosa meet significantly influences the outcome of the interspecific competition between them. L. biglobosa can inhibit the production of sirodesmin PL and the growth of L. maculans if it is inoculated before L. maculans or less than 3 days after L. maculans in liquid culture. There is a need to further investigate the timing of co-inoculation on interactions between L. maculans and L. biglobosa in their host plants for improving the control of phoma stem canker.
