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 […]

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. […]

Petal fall approaching for many; Bloom for others

By Terence Bradshaw As has been the general case this year with the drawn-out, cool weather, we have bloom (and p-bloom) bud stages all over the place depending on elevation, proximity to the lake, cultivar, and latitude. For growers in upland sites just entering bloom, see my posts from the past couple of weeks that […]

Fire blight pt II

By Terence Bradshaw Sometimes you need to check the latest weather before hitting ‘send’… After I just sent that last missive, I double-checked conditions in western Vermont, specifically Shoreham and Bennington, and the weather prediction is indeed for warmer weather than when I last looked. NEWA is now calling for “Infection” on Monday for those […]

Apple scab, what would we do without you?

By Terence Bradshaw Here’s a quick note to remind everyone that we’re in the middle of an extended wetting and apple scab infection period that is likely to peak on Monday. Every orchard in the state still has mature ascospores in the leaf litter from last year, so stay protected. We’re also still in rust […]

Apple scab infection period now… (May 13)

By Terence Bradshaw This is a very brief message to Vermont apple growers that we are in a dry and relatively windless slot between significant wetting events and it would be wise to make sure that your fungicide coverage is maintained. I wouldn’t worry about insects now, unless you are treating for scale, but a […]

Pest management in orchards this week, May 5

By Terence Bradshaw First note, please remember that we will be hosting an Orchard Scouting Field Workshop at the UVM HREC on May 16, 1-4 PM to help growers with implementing scouting programs and to discuss upcoming management strategies. I’ll have a registration link ready later this week. The event will be free, but I’m […]
