I just wanted to do a quick update on blast. I have not seen any other blast besides the one I reported on an earlier post. PCAs that I have spoken to have not seen blast either. With the cooler temperatures, conditions for blast are not as good. The hours of leaf wetness (LW) required for infection are higher when temperatures are cooler (see figures below). We'll see what happens as temperatures warm up again, but we know that as the crop matures, blast infections are less likely. However, I don't want to say we won't see any blast - last year we saw blast infect some fields late in the season. We'll keep monitoring.
