March 21. Applied lime sulfur spray. Some bud break but still applied in near dormant strength. Have seen no evidence of damage.
April 1 (approx). Applied roundup. Moderately effective.
April 6. Applied nova, mancozeb and Captan. Some shoots, as on de Chaunac, about one and a half inches
April 24 Similar application. Frost damage on most vines, esp. de Chaunac which suffered better than 50% loss of early grapes. All vines show some shoots, though buds still breaking on most plants.
May 3 Quintec, Captan and Mancozeb. Probably the last application of mancozeb, especially if there is an early harvest. Niagaras are coming on nicely and the Cayuga Whites look good. Need to thin out some clusters on those since they are just 3 year plants. Some others need thinning as well.
May 14 Quintec and Captan. Removed broken twigs (deer have really been after some of the top new shoots. I've lost even more grapes now.) We will have a harvest, but it will pale in comparison with last year's.
I added bentonite to the Niagara since it just has not cleared up very well yet. I'm dubious about this working well.
May 26 Nova, Captan and sulphur. I used the minimal amount of sulfur. We'll see if there is any damage to the plants.
June 4 Quintec and Copper. Some possible burning of new leaves from the sulfur on the Nortons. Otherwise, no apparent damage. Trying the copper this time. Again, 2 oz per gallon. Plants are looking good, more grapes than I had thought. Since there are some larger grapes as well as very small, 2nd bloomers, I'll need to decide which to thin and when. Need to research that.
Bad news: first Japanese beetles of the season. Way too early.
