I signed up for an automatic alert when late blight is spotted within 200 miles of our Gardens. Here is the website http://usablight.org/alerts. There is no need to spray unless late blight spores are in the area - so this seems like a good system. Once I get a notification, I'm planning to spray with Copper fungicide (Bordeaux) alternating with Oxidate (Johnny's recommends this) every 7 to 10 days and before and after rains.
