One (or two) more things to think about

By Terence Bradshaw I’ve received questions about a couple of questions about two different yet similar insect pests: grape tumid gallmaker (GTG) and phylloxera. Both of these insects cause galls that develop around larvae that feed on foliar (and fruit, in the case of GTG) tissue which can be quite concerning, but often are not […]

Post-heat wave vineyard management

By Terence Bradshaw It’s cooling off for a bit, time to think about activities in the vineyard. Thankfully, extreme heat isn’t good for most grape diseases, and the dry weather hasn’t been good for them either. However, berries are sizing up and bunch closure will be here before we know it, so we should consider […]

Cooling off orchard activities

By Terence Bradshaw Now that we have a respite from the heat wave, I imagine growers are thinking about what needs to be managed in Vermont orchards. As a rule, there aren’t any across-the-state IPM issues that I expect every grower will be facing. In warmer areas, it’s still a decent time to apply a […]

Spraying and hot weather

By Terence Bradshaw This is just a quick note to urge caution for anyone planning to spray grapes or apples ahead of the upcoming hot spell which is expected to start tomorrow. Meteorologists are calling already saying that this may be the most intense heat event seen in Vermont in recent history, particularly in terms […]

Vineyard management, June 25

By Terence Bradshaw Things haven’t changed all that much in Vermont vineyards since the last posting here. Despite the showers over this past weekend and a pretty good rain last Monday, the predominant weather feature has been dryness. That’s good for most diseases, and as we shift into the postbloom period, we need to also […]

Orchard IPM, June 24

By Terence Bradshaw Things are a bit quiet in the orchards right now. Primary scab season is done, and there is little of it in commercial orchards where dry conditions and easy spray windows have allowed for decent disease management conditions. Fire blight- a minor annoyance in some orchards and absent in most, but keep […]

Early summer orchard considerations

By Terence Bradshaw I’m not sure if everyone reads all the way to the bottom of my postings, or if things are going fine in Vermont orchards. If you recall, I was away working with apple growers and aspiring cider makers in Lebanon May 26-June 10, and was mostly unreachable. That I heard very little […]

Immediate prebloom in grapes

By Terence Bradshaw Grape bloom is looming in many Vermont vineyards, and this is a critical time for disease and vine management. As we mention in our initial IPM strategy for winegrapes, all of the major diseases save for late-season fruit rots are sensitive to management right now. That means that fungicide applications should be […]

Early season vineyard management

By Terence Bradshaw Grapes are moving fast in Vermont vineyards, with most cultivars in the UVM vineyard at about 3” shoot growth. Shoot thinning now will give best results before the vines waste energy on growth that you won’t keep. We typically aim for 4-6 well-spaced shoots per foot of canopy, selecting for the most […]
