Since some fungicide treatments for rot control may need to be applied early in the season assessment of orchard factors needs to be done initially pre-bloom and repeated nearer harvest. Near harvest assessments of inoculum are particularly important for …
Keeping records for individual orchards, of losses due to rots, and the fungi responsible, when the fruit is being graded from store can provide valuable information on the current problems in the orchard and the ones likely to occur in future. The …
The mineral composition of fruits is closely correlated to the level of rots found after medium or long-term Controlled Atmosphere (CA) storage. Increased levels of nitrogen and potassium are associated with higher levels of rots while increased calcium …

Research has shown that Cox orchards vary considerably in the actual losses due to rots in store and the main fungi responsible for the losses. Therefore, actual rotting in store is very much related to orchard site. The purpose of rot risk assessment is …
