Just have to state my annoyance that the news on NPR today warned farmers and gardeners to prevent late blight by spraying "pesticides." ARG! I am compelled to scream at them every time FUNGICIDES! FUNGICIDES!
Ahem. Back to your regularly scheduled programming.
I found the reference NPR took, it's here: http://www.wetmtv.com/news/national/story/Tomato-growers-told-to-ta...
"Cornell University plant pathologist Meg McGrath says tomato growers can
spray pesticides to try to prevent infection, but once late blight
takes hold, the plants are lost."
