Detection of latent infections of Monilinia fructicola in plum fruits

In Canada, experiments were carried out to develop a detection method for latent Monilinia fructicola (EPPO A1 pest) in immature plum fruits. Plums were surface-disinfected, treated with paraquat and subsequently incubated at 95% relative humidity in 250 ml jars in light. As controls non-paraquat samples were incubated at 25ø C in dark or light.

It was found that the paraquat treatment enhanced the M. fructicola development. 40% of the paraquat-treated fruits rotted after 5 days while non-paraquat-treated fruits rotted after 11 and 14 days, respectively.
