Vineyard management at bloom

By Terence Bradshaw Many vineyards are in bloom across Vermont, and inflorescence looks good and bodes well for a promising year. As I’ve been saying all along, be sure to maintain spray coverage for the next couple of weeks; to remove any diseased tissue as you find it; and to do your best to maintain […]

Apple maggot fly traps

By Terence Bradshaw The time has come to hang apple maggot fly (AMF) traps in Vermont orchards. Last year, we saw higher populations state-wide, for which I don’t really have a good explanation. These are some of the easiest pests to manage using an IPM strategy, so there’s really no excuse. The idea is to […]

July 9 UVM Grape Canopy Management Workshop

By Terence Bradshaw Summer canopy management is one of the most important tasks for producing high-quality winegrapes, especially in cool/cold regions where ripening can be impacted by low heat unit accumulation. The tasks taken to open and manage canopies aren’t necessarily intuitive, and are often overlooked by beginning fruit growers. Join the UVM Fruit Program […]

Grape pest management, June 19

By Terence Bradshaw June 19, 2019 It’s always impressive to me how fast grapevines can go from zero to full foliage in a matter of a couple of weeks. Vines at the UVM Horticulture Research & Education Center are generally at 16-24” shoot growth. We’re not quite at “Immediate Pre-Bloom” stage, but not far off, […]

Petal fall and then some (sometimes quite a bit more)…

By Terence Bradshaw Orchards in the highest elevation and coolest areas are at or just past petal fall, so all the advice I’ve had for other growers applies there as well now. All orchards should have started or, more likely, completed chemical thinning by now. Fabulous thinning weather occurred last week and those who applied […]

Expect insect activity to pick up later this week

By Terence Bradshaw Finally, it looks like we’ll be entering an extended stretch of warm, sunny weather starting Thursday and especially Friday and lasting through the weekend. In South Burlington, we’re expecting temperatures just near 80°F by Sunday. That is great weather to drive plum curculio and European apple sawfly activity, so I suggest treating […]

Orchard management at petal fall (and then some)

By Terence Bradshaw This week I’ll just say, “more of the same…” Apple scab primary ascospore season is done or nearly done in Vermont orchards. Check carefully for apple scab in your orchards before stopping fungicide coverage. Lesions can take two weeks to appear, so you may not see the latest infections for a bit. […]

Grape disease management and shoot thinning

By Terence Bradshaw I’m probably a tad late on getting this out for some growers. The growing season continues to be cool and wet, and grapevines at the UVM Horticulture Research & Education Center are showing about four to five inches of shoot growth. We are beginning to enter a critical time for disease management. […]
