Pink rot has been reported in some fields this season. Learn more about pink rot and leak management here.

Even if a field has been treated with fungicide during the season to manage pink rot, the disease can still develop. Infected tubers can contaminate healthy tubers during the harvest operations leading to additional disease development in storage.

The use of phosphorous acid applied at harvest is an effective method of reducing this contamination. However, the postharvest application can be difficult from a logistical standpoint. The attachment below is a presentation given at the Idaho Potato Conference this past January and brieflly discusses pink rot management, including postharvest applications of phosphorous acid. Some information on Pythium leak is also presented.
