EAS, FB, CG…observations from this week.

By Terence Bradshaw June 10, 2017 CPS crop consultant Eric Boire sent me this picture yesterday of what, on first glance, looks like a first generation codling moth larvae burrowed into an apple at about 10-12 mm growth stage: Figure 1. European apple sawfly damage posing as codling moth injury. We have seen this a […]

Grape tumid gall maker- curiosity and management

By Terence Bradshaw June 8, 2017 One of the great things about growing grapes in Vermont is that, by and large (and compared to my other crop, apples), the pest management is relatively simple- four or so well-timed fungicides sprays, and an insecticide aimed at grape berry moth. There are other considerations for unique situations: […]

Codling moth and other pest management in apples

By Terence Bradshaw Codling moth (CM) management is just around the corner in many Vermont orchards. This is an increasing pest in the state- many orchards never had a problem until recently, and some still don’t. Adults begin flying around bloom, and our monitoring program is designed to catch the first flight to tie later […]

Vineyard management approaching bloom

By Terence Bradshaw Grapes are at 10-12” growth in most Vermont vineyards, and combined with the wet, cool, rainy weather, are at prime susceptibility for phomopsis, black rot, and anthracnose. Fungicide coverage should be maintained on 7-10 day intervals during this extended rainy stretch; if it dries out as expected at the end of the […]

Orchard management at fruit set

By Terence Bradshaw By now virtually all orchards, including those in cooler regions, are at petal fall with only straggling bloom around on later cultivars. The cool weather has shut down concerns for continued blossom infections of fire blight. If infection did occur in your orchard during the May 18-20 warm spell (wouldn’t we love […]

Vineyard management: Diseases and shoot thinning

By Terence Bradshaw 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. Growers should consider applying a protective fungicide soon that has activity against […]

Petal fall apple recommendations for Vermont orchards

By Terence Bradshaw Below are some notes I’ve taken, including my own thoughts and observations, from today’s Champlain Valley Petal Fall meeting hosted by Cornell Cooperative Extension. Thanks to Extension Associate Anna Wallis, plant pathologist Dr. Srdjan Acimovic, entomologist Peter Jentsch, plant physioloigist Dr. Poliana Francescatto, and consultant Jim Eaves for contributing to these observations […]

Important clarification- 5/23 New York Petal Fall meeting, no tour

By Terence Bradshaw Sorry folks, I’ve advertised a tour that doesn’t exist. The Tuesday, May 23rd petal fall meeting will be held at 3:00 at Rulf’s Orchard in Peru, NY. There is no pre-meeting tour. 3PM: Thinning Meeting, Rulfs Orchard, 531 Bear Swamp Rd, Peru Cornell Fruit Program Champlain Valley Petal Fall Meeting Tuesday May […]

Petal fall pre-discussion

By Terence Bradshaw May 21, 2017 Most Champlain, Connecticut, and Taconic valley orchards are at petal fall or quickly approaching it, which means the management needs will ramp up quickly- insect and disease management; nutrient application, mowing/herbicide/cultivation; and, of course, thinning. I’ll be wrapping my head around thinning options in the next few days, but […]

Disease management in Vermont grapes- the season begins

By Terence Bradshaw Grapes are moving fast in Vermont vineyards, with most cultivars in the UVM vineyard at about 2” 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 […]
