(Today’s picture is our friend Phomopsis again!
Left side has more spots probably because it is closer to the vine
where the fungus survives and produce spores.
Spores were rain splashed to the leaf to cause infection.)

It seems that pretty much all over Virginia is expecting some type of rain during next few days. I do not know how “30-40% chance of thunderstorm” turns out, but if your last spray was more than two weeks ago and/or your vines have grown a lot from the last application, then you may need to be prepared for these chances of rains. As I noted yesterday, please adjust your spray materials and spray amount based on your vine’s growth stage.
