Happy New Year!
The folks at Michigan State University Extension are offering a webinar on Tuesday, January 13 at 1 pm ET called, “Your Lungs, Your Life: Respiratory Disease in Hop Growing and Processing.”
The one-hour webinar will include speakers Carolyn Whitaker and Dr. Dave Bonauto from the Washington State Department of Labor and Industries Safety & Health Assessment & Research for Prevention (SHARP) Program.
In this webinar, you will learn how to keep your lungs healthy while growing and processing hops. It will cover what to watch for, when to see a doctor, hop jobs associated with respiratory disease, and what you can do to protect yourself and employees.
No registration is required and the program is free. Simply click the following link five minutes before the webinar is scheduled to begin https://connect.msu.edu/erinlizotte. Please sign in as a guest using your first name and state of residence. You will need a computer with internet access, a web browser (e.g. Explorer, Safari) and speakers. Don’t worry if you aren’t available on January 13th, the webinar recording will be made available at hops.msu.edu.

Please note that the UVM Cereal Grain Testing Laboratory will be closed for the holidays beginning Monday, Dec 22, 2014 and reopening Monday, Jan 5, 2015. It would be best to hold on to your hop samples until after the 5th. Thanks.
Best wishes for happy holidays! And, keep calm and hop on…

Hey all, If you haven’t seen it yet, WCAX, our local CBS affiliate, highlighted our hop research in a recent “Sunday Science” feature. Take a look!

We tested ~ 30g of our early varieties on August 8th and harvested our first Saaz plot of the season on August 12th at the research hopyard in Alburgh, VT. Several of our early and mid-season varieties are ready to harvest.
Please continue to practice meticulous hop processing so that our local brewers have excellent hops this year!
A few harvesting tips to ensure high quality:
- Take pre-harvest moisture samples (see our Hop Harvest Readiness Factsheet)
- Cut down only what you can pick that same day
- Keep your cut hops out of the sun
- Dry your hops to 8% moisture
- Seal your dried hops or pellets and freeze
Check out our easy to use online harvest moisture calculator or download your own copy.

Take a deep breath; help is on the way!
Figure 1. Japanese beetles with winsome fly eggs on their thorax (Scott A. Lewins)
While scouting a hopyard in central Vermont, UVM Extension Entomologist Scott Lewins photographed these Japanese beetles last week with some deadly companions on their backs (Figure 1). The white dots on the thorax of the Japanese beetle in the picture are eggs of a parasitic fly brought here years ago to help control this destructive invasive species.
The winsome fly, Istocheta aldrichi (Figure 2), is a parasitic fly native to Japan, where it is one of the most effective parasites of Japanese beetles. Female flies lay their eggs on the thorax of newly-emerged Japanese beetles. After the eggs hatch, the parasitic maggots burrow into their Japanese beetle host, killing them in five to six days. The beetle rapidly dies as the maggots eat it from the inside out. This often means that the targeted beetles never reproduce. The fly completes its lifecycle within the body of the dead beetle, emerging the following year.
Figure 2. The adult winsome fly (http://bugguide.net/node/view/346199)
The USDA first introduced the winsome fly in the United States in 1922 to try to combat Japanese beetles. Their introduction has been slow to take hold throughout the US, but has become well-established in New England since their introduction. The winsome fly and Japanese beetles are not as well-synchronized within the US as they are in their native Japan. Unfortunately, the fly emerges earlier than the beetle so we don’t realize the full benefit of Japanese beetle control. Despite this asynchrony, parasitization rates of more than 20% have been observed.
In order to encourage winsome flies in the landscape, there are ways to manipulate the habitat to benefit them. Adult flies feed on the nectar of umbelliferous flowers like yarrow, hemlock, Queen Anne’s lace and parsnip. Providing food sources for adult flies will attract them to the area, and when Japanese beetles begin to emerge, the winsome fly will be ready to do what it was brought here for.

We are excited to announce that Trevor Hardy from Brookdale Fruit Farm will be at our Annual Crops and Soil Field Day THIS THURSDAY, July 24th in Alburgh, VT. He owns an irrigation company in Hollis, NH and will be sharing his expertise on the important topics of irrigation and fertigation.
Please join us!

Disease: Downy mildew is our biggest pest problem this year in Vermont. Due to the lasting rainy weather, we continue to see aerial and basal spikes appear. For disease control in the Alburgh, VT research hopyard, we spray an organic fungicide weekly. We also have a new crowning trial this season that you can check out at our field day on July 24th at Borderview Farm!
Arthropods: On the arthropod side of pest management we have been finding medium levels of the major hop arthropod pests in Vermont. Hop aphids, two spotted spider mites, and potato leafhoppers are all present, yet have remained well below actionable levels. The harsh, long winter that our region experienced this year is certainly part of the reason for lower arthropod populations. A few Japanese beetles and various caterpillar species (Eastern comma and hop looper) have also been scouted. As a result of not applying insecticides thus far in our research yard, we have been able to avoid secondary outbreaks of spider mites and aphids. When broad spectrum insecticides are sprayed, beneficial arthropods are killed allowing pest arthropod populations to increase rapidly. See our major and minor arthropod pest fact sheets on our website under News from the Field.
Early Hop Cones: It has been observed across the country that cones are developing early. In our hopyard, ‘Saaz’ as of July 1, 2014 already had full sized cones and will be ready to harvest in a few weeks. It is unclear as to why we are seeing this trend but it is nationwide. Tell us what you’re seeing on our UVM Extension Crops and Soils facebook page!

We began irrigating on the week of June 1st and will continue to irrigate until harvest at the end of August. Hops require a lot of water! We strongly recommend that you irrigate, and once you are done, irrigate some more. Chris Lattak of the Trickl-eez irrigation company recommends 16 gallons per plant per week. That’s a hard number to hit – we won’t be reaching it because we’d run the well dry – but it’s a good goal. For evidence to the value in irrigation, see this recent SARE grant study from Aroostook Farm in Maine: http://www.aroostookhops.com/uploads/SAREFinalReport2012FNE11-711.pdf. This year we also added a fertigation system, which applies fertilizer through the drip irrigation. The fertigation started the week of June 9th. More information to come on our fertigation system.

We have been receiving inquiries as to Downy Mildew diagnosis and management techniques. Our Downy Mildew fact sheet (Link is below) has quite a bit of information that can be helpful. As always, please contact us if you have specific questions, or if we can elaborate on anything found within the fact sheet.
