The best time to apply a fungicide such as Eagle 20EW will depend on what type of plant you are treating, the type of fungus you are trying to prevent and the region you are located in. We recommend reading over the product label available on the Eagle 20EW page on our website or contacting your local cooperative extension office and speaking directly to the master gardener on staff. Master gardeners are experts on the plants and plant diseases in their local region and they should be able to tell you exactly when you should perform the application.
