Buds are bursting- 2020 season is on a roll
By Terence Bradshaw Growth in the UVM vineyard ranges from bud burst to 2-3 shoots emerged; a few shoots are nearing three inches in length. It’s time to really be thinking about protecting vines from early season disease infections. Most cold-climate cultivars will not need disease protection until 5-8” of shoot growth, but any vineyards…

Petal fall
By Terence Bradshaw I know that some orchards are still in bloom, so the thinning and insect management portions of this message may not pertain. Hopefully everyone with any hint of risk for fire blight has treated sometime during this heat spell. Cooler weather this weekend and rapidly dropping blossoms will decrease risk, but until…

Petal fall and spraying this week
By Terence Bradshaw What an amazing weekend it’s been, weather-wise. I still need to check bud stages, my cider varieties here at 1500’ elevation in central Vermont are still at around half-inch green, and so are not an indicator of what things look like around the state in more typical orchards. However, I imagine many…

Fire blight & streptomycin questions
By Terence Bradshaw I’ve received a few questions about the fire blight alert: If you are in an inland/upland site and no bloom or fresh pruning wounds, this alert does not apply. However, I bet most apples in the state, aside from some late cider varieties, will be in bloom before this disease alert is…

Fire blight alert

I’m seeing sustained warm, sunny, relatively windless, and dry conditions for the next 5-7 days, with increasing risk of rain as next…

Bloom, apple IPM
By Terence Bradshaw Apple bloom has started in much of the state, and the weather looks about as good as it gets for pollination and fertilization. It’s been dry since last Friday, and, in most sites, that rain wasn’t even as much as expected. So, water if you can, trees in bloom and setting fruit…

The goal of the survey is to guide future research and extension efforts in this area. The survey is completely anonymous. You can complete the survey by…

Buds swelling in local vineyards
By Terence Bradshaw Grapevine buds are showing significant swelling in vineyards both in the Champlain Valley and at my house at near-1500 feet in Washington County, so bud break is right around the corner. However, This extended cool weather expected this week will leave those buds in this swollen state for an extended period, which…
