Diseased!

This morning was Pinot grigio harvest day in Vinoland.  The fruit looked beautiful and the numbers came in at 27° Brix, a pH of 3.55 and TA at 6.75 - all in a good range.
The 2018 fruit may be in Vinomaker's capable hands now, but I am already thinking ahead to next year and some critical vineyard operations that will ensure a 2019 harvest.  Pruning, of course, is next up, but there is also a bit of replanting to be done.
Alas, there is evidence of Pierce's Disease (PD) in some vines (nine, one right after the other, in one row and at least one vine in the row above them).  The PD symptoms first appeared last year, but this year they are more definitely pronounced; foliar scorching, irregular bark maturity and raisining of the fruit, or, (as demonstrated in the above photograph) miniature clusters (a mere 2.4 inches).
Oh well, it'll give me something to do next spring.
