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.

I have put together an article for our Lottie Newsletter on using Aspirin water to help plants to deter blight after having seen the info I spoke to you about. Further research I did found that a large pharmaceutical company recently started selling Aspirin products for gardeners, so it must work for them to have picked up the research and gone with it. The bordeaux mix is ready to be deployed too!
