The Problem - Brown Rot

Brown rot (Monilinia fruiticola) is the most economically devastating disease for stonefruit growers. Infections can result in yield losses through fruit rots at harvest. Latent infections not visible at harvest develop into rots in storage and reduce shelf life in the post-harvest food chain.

Cultural techniques including maintaining an open canopy, removing diseased wood and removing mummified fruits can assist by reducing inoculum sources in the orchard. However for economic control a seasonal fungicide programme is required. The critical periods for fungicide applications are through the key infection periods – from early flowering through shuck fall and pre-harvest.
