New York, New England, Canada Fruit Pest Management Conference

I'm on a roll. So, in mid-October 2018 I was up in Burlington, VT with a group of fellow-minded (mostly tree fruit) Extension, research, and consultant folks from the New England states (mostly), New York, and our friends up north, Canada (mostly Quebec). This is the our 82nd get-together, believe it or not. I've been probably close to 25 times beginning with my work at University of Vermont and continuing with my 18 years at UMass, during which I don't think I have missed a year? There were just over 30 of us, as evidenced by this group photo:

We reported on special orchard problems during the past growing season, gave research and Extension reports/updates, and much enjoyed a regional beverage tasting, all at the Bishop Booth Conference Center on the shore of beautiful Lake Champlain. You can further investigate this Tree Fruit Working Group on the Northeastern IPM Center website, including reports and research presentations. (2018 to be posted soon I hope.)

But we had a special guest, Peter Triloff, a consultant from the Lake Constance region of southern Germany. Peter was being hosted by Vincent Philion up in Quebec, so they came to the meeting togeher, and Peter gave an update on canopy adjusted spraying. Wow, kind of blew away some conventional wisdom I had, such as going slower equals better spray coverage (not necessarily) and that air-induction (AI) nozzles are NOT the way to go, because drift reduction, although important, should not be priority when spraying. What is priority? Better coverage while still controlling drift. AI nozzles do not give you as good spray coverage compared to regular hollow cone nozzles with finer droplets. So how do they achieve higher spray coverage with smaller droplets while controlling drift? Peter says by modifying the air flow to match the canopy, which includes throttling down while speeding up.

Now, there are many fine points, but there is one major talking point: radial fans are a disaster if we are talking tall-spindle type trees. (And why would we talk anything else?) A tower (vertical air flow pattern) is the only way to go. I certainly get the impression spray technology over there is way ahead of us. And they have restrictions, such as wind speed limits (app. 8 mph?), sprayer inspections, and full sprayer clean-out between tank mixes. Peter's talk also honed in on the money and time saving that could be achieved by speeding up while still maintaing good coverage. Diesel fuel savings too which they seem to be into out there. AND, pesticide use reduction by about 2/3 because spray is not going on the ground or drifting! Target the canopy and save money, time, and reduce pesticide use. What's not to like? Here is a presentation on this subject from 2014 given by Peter Triloff at Interpoma in Italy. The presentation he gave in Vermont was updated and quite thought provoking. Mostly, we could do a lot better with our spray application technology here in Massachusetts, New England, and the Northeast? I present my case:

IFTA New Zealand 2018

I admit to being lame and not publishing a blog post in almost a year. It's been a busy year with lot's going on, so I ought to make an attempt to get back in the saddle. (No promises.) Will start with a big deal, I was lucky enough to spend almost two weeks in New Zealand last February with the International Fruit Tree Association. Mostly I want to share with you a photo album I put together, but here's a (very) quick synopsis of my trip.

IFTA New Zealand 2018 attendees.

First stop Napier, on the North Island. I liked the public water pool/hot tubs after a long series of flights that spanned two days. One-day IFTA Conference to kick things off, intro to New Zealand apple production and some pretty technical production talks. Of course you know NZ is now famous for Jazz, Pacific Rose, and more recently Envy but don't forget Granny Smith, Gala, and Braeburn also originated in New Zealand! Two full days or orchard tours in the Hawke's Bay apple growing region. Many highlights including NZ Plant & Food Research (Future Orchard Production System), Prevar, and Rockit apples. Very technical and detail-oriented apple orchards, apple quality is key given the money is in export apples. We had a day off with guided activity options, I chose a bike ride along the coast and sheep country topped off by lunch at a winery. With wine of course! Made the bike ride into a stiff wind back to point of origin kind of onerous, but overall the day was a great one.

Public pool/hot tub beachside in Napier. Sweet.

After a short Island hop courtesy of a chartered Air New Zealand flight we landed in Nelson. Nelson is a rather cool place with a downtown filled with shops, bars and restaurants. Two full days of orchard tours in Nelson/Tasman Region. Again, highly technical apple growing, including Drape Net demonstration, 2D apple canopies, and grafting. Another day off with a group trip to Abel Tasman National Park. Choice of activities, I opted for Catamaran ride. Needless to say it was great. While in Nelson, I also caught a glimpse of the "Crux" aka Southern Cross constellation one evening.

Dr. Greg Lang. You think he is enjoying the Cat?

Departing Nelson on bus, destination Christchurch, we stopped in Kaikura. Again, choice of group activities, I went swimming with dolphins. Whoaa, that was an experience, wet suit and mask/snorkel, flippers and all. Whisked off back of boat, saw dolphins, whistled back on boat. Several/many times. Exhausting, ever seen the movie "Open Water?" Thought crossed my mind.

OK, one day of orchard tour out of Christchurch to Timaru Region, one orchard, M A Orchards, first (and only?) Honeycrisp planted in NZ in 2012. Large red apples being harvested, bound for North America. Of concern was some significant drop. Reflective fabric in place. Very interesting.

Thanks to IFTA, all our NZ hosts and sponsors, and Onward Travel for making it all a pretty seamless experience with good orchards, good food, good company and entertainment, good scenery, good recreation. And to WSU's Karen Lewis who did two rounds of hosting over a period of a month.  Every stop/activity times two. She has special skill, knowledge, and stamina to be able to go the mile (kilometer?), and we all appreciated her presence many times over.

Karen Lewis, fearless leader. The end is near...
