Brown rot, caused by Monilinia fructicola (G. Wint.) Honey, is a destructive disease of stone fruits (Prunus spp.). The disease expresses as blossom blight and fruit rot. In spring, ascospores or conidia produced from mummies infected by M.
(Flower Incubation Technique, FIT) Before using the risk analysis approach to estimate the possible risks of blossom blight and latent infection for a specific orchard, the inoculum potential of the orchard should be determined.
This technique can be used to determine the latent infection of fruit caused by Monilinia fructicola. Immature fruit collected from orchards could be used to determine the incidence of latent infection. Surface sterilize the fruit in a chlorine solution (32 ml of 0.
