As well as having a quick look at some Sancerre vineyards on Monday we also crossed over the Loire into Burgundy to have a look at Pouilly-Fumé. Again as in Sancerre there is some rot but from what I saw (a rapis impression) it is not too serious assuming that the weather remains dry and sunny with fairly low humidity. If there is rain, especially with high humidity and little wind, then the situation could turn nasty. Fingers crossed it won't.
