It’s time to consider ReTain applications in Vermont orchards
The use of plant growth regulators to help with harvest management and improve fruit quality is an important tool in many orchards. ReTain plant growth regulator is used to slow ethylene synthesis in ripening fruit to delay maturity and reduce preharvest drop. Given the dry and hot conditions experienced this summer, drop potential is high,…

This is an important time of year for a…

Vermont Apple IPM: Mid-late summer apple insects and diseases
Apple maggot fly captures are increasing in some orchards.

This will allow for activity and eventual wash off prior to harvest. Check the…

Vermont Apple IPM: Midsummer management
This has really been a bit of a goldilocks season, with relatively mild, or dare I say ‘normal’ temperatures, few significant weather calamities, and just enough rain to keep us from complaining too much. That generally means low tree stress, and with the reports I’m hearing from growers and the observations I’ve made around the…

VT Grape IPM: Diseases showing up in area vineyards
The main management items that should be on the minds of growers right now are disease management, groundcover management, disease management, and maybe some insect management. Canopy management probably needs to wait a little bit. We have been seeing some symptoms of Phomopsis, a little black rot, and some downy mildew in the vineyards we…

VT Apple IPM- Apple maggot fly traps should be prepared and hung
Assuming that you have dealt with codling moth, we’re in a calm spot between insects but it is time to hang your apple maggot fly (AMF) traps. These are some of the easiest pests to manage using an IPM strategy, so there’s really no excuse. The idea is to assess the population in the orchard…

VT Apple IPM Codling moth management due any time
At the UVM Horticulture Research and Education Center, we caught our first codling moth in our pheromone traps on Thursday, May 26. Using that day as a biofix, we start accumulating degree days (base 50°), or rather let NEWA accumulate them, and plan to apply a treatment at egg hatch. Most literature references 220 DD…

Vermont Grape IPM: Peak Disease Management
We seem to be in a Goldilocks sweet spot in regards to moisture- just enough for the vines, not too wet to get work done. That can let some folks get complacent, but as vines are entering the immediate prebloom period, we are at peak disease pressure with all of the major diseases active to…
