Not at all...I’m probably behind the curve on that one. I’ve got some time to figure it out right? Maybe a couple weeks or longer before first application? Post bud break right??Exciting! Do you have your spray plan figured out?
Yes, you’ll need to start spraying at 1/2-1” shoots. What you’re doing is on a much larger scale than my 75 vines so you might want to check with some commercial growers in your area, but I reckon you should at least get yourself ready with some mancozeb as black rot will be your early enemy and the commercial growers I’ve spoken with use it as I do (6 applications/year with a 66 day pre-harvest interval). Throw in some sulfur as well for powdery mildew, especially since you can spray with it all season. Since 2019 I also spray early with BT for caterpillars. I’m not sure about what is available in Maryland, but Virginia Tech has an extremely helpful grape disease blog that I follow and have learned a ton from. They just updated their spray schedule template which I modified for my home use and you might want to take a look at: Fungicide application template, a table of fungicide resistance, and upcoming meetings. They also have a new online tool www.grapeipm.org for tracking your sprays and materials that I’ve only just started messing around with but looks pretty cool. Also, this may sound obvious but keep your fungicide sprayer separate from the one you use for weed killer. Good luck - you’ve got a big investment of time and money to protect!Not at all...I’m probably behind the curve on that one. I’ve got some time to figure it out right?

any help you can give is appreciated.
Can’t wait to see how the season goes for you!Epic weekend, planted the last of the 278 vines for this year. Waiting on some bamboo for the last grow tubes and I’m short a few trellis posts but things are shaping up.
