From graduate student Vinay Pagay:

Chair Marvin Pritts took a group of horticulture graduate students to Shindagin Hollow State Forest on Friday, May 20, for an afternoon hike to observe some natural vegetation — trees, shrubs, and wildflowers, many of which were in bloom then. It was a fun and educational afternoon for all of us, and the wildflowers were wonderful. (See the wall of trilliums below.)

From Allison Chatrchyan, CCE-Dutchess County amc256@cornell.edu:

Cornell University faculty, staff and Cornell Cooperative Extension (CCE) educators recently formed a new Program Work Team (PWT) to develop and disseminate information on how climate change will affect New York State. Collectively, the Climate Change PWT members will be developing research-based materials describing how climate change will affect New York’s communities and resources, and how individuals, communities, and stakeholders can both mitigate their impacts on the climate and adapt to the climate changes that will continue to occur.

More information is available via our website (http://www.climatechange.cornell.edu) and we will continually update and add new resources to that site. The PWT will be communicating with stakeholders via a Cornell email listserve, and organizing several meetings and training opportunities per year.

Please let us know if you would like to be involved with the PWT, would like more information, or have suggestions on information needs of groups you work with. We can be reached by emailing Dave Wolfe (dww5@cornell.edu) and Allison Chatrchyan (amc256@cornell.edu).

Fifth in a series of profiles celebrating the Class of 2011.

Majors: Plant Sciences, Viticulture and Enology

Hometown: Rochester, N.Y.

Why did you choose Cornell?

I was always interested in plants. As an Eagle Scout project, I renovated the landscaping at the Ronald McDonald House in Rochester. And I helped my father convert an apple orchard and cider mill into a vineyard and winery, planting 40 acres of vines by hand and producing our first wines in 2006. (Mayers Lake Ontario Winery.) I knew Cornell was good in Plant Sciences and had started a Viticulture and Enology major, so it was a good match. And if I decided to go the pre-med route I could do that too.

What was the best part of your Cornell education?

Cornell gave me chance to do my own research and get involved as a teaching assistant for four of the viticulture and enology courses. I did wine chemistry research with Kathy Arnink, vine stress physiology research on Riesling and methoxypyrazine research on Cabernet Franc with Alan Lakso. I also worked with Kathy, Ian Merwin and other students to plan and plant Cornell’s first organic vineyard at Cornell Orchards. Some of this research was the first of its kind in my field. This was great for me because of my commitment to research and teaching, and most importantly giving back to field.

What Cornell-related scholarships did you receive?

The Nelson J. Shaulis Award for the Advancement of Viticulture supported my research with Alan.

Who or what influenced your Cornell education the most?

All of the faculty I did research with, especially Kathy. She really took my under her wing and was a great role model. Much of what she instilled in me as a young student has transferred to the present day mostly in the form of my love for research and my commitment to the students and to Viticulture and Enology. Peter Cousins is a great teacher, role model and friend. He spent many hours working with me in a hands-on way to learn the aspects of modern viticulture and basic grape genetics and physiology.

I really liked the hands-on nature of my education here. I was one of the first students to experience all of the aspects of the Cornell Viticulture and Enology program. I was able to develop my own research projects, grow and plant grapevines, harvest the grapes, and conduct experimental winemaking trials based on my own program. I analyzed the wines chemically and physically, and was able to conduct my own research panel from this and teach about my research to a large introductory class as a Teaching Assistant. I could not ask for much more!

What were your main extracurricular activities at Cornell?

I worked as an Orientation Leader and an Orientation Supervisor for New Student Orientation. I spent many hours working with students even after Orientation ended, sharing experiences and helping them through their day-to-day problems. I still keep in touch with many of my students. New-student Orientation took tons of time but it was great for me to be able to share my love for Cornell with all of the new students.

I was also a Social Programming Director in Willard Straight Hall, planning dances, concerts, and weekly events that were attended by many students. I worked for Colleges against Cancer on the programming board, using my time to implement two Relays for Life. I was the Social Programming Director for my fraternity in which I implemented a program in conjunction with the Ithaca Youth Bureau that has raised over $6,000 to date.

And in 2009 I started a company called in2ition music with my friend Kai Keane. We create videos and musical interpretations of electronic music for events all around campus and Cornell. Recently, we developed a show for the Johnson Art Museum’s recent gallery opening. You can find us at www.facebook.com/in2itionmusic.

What was one of your greatest challenges at Cornell?

The coursework. It was difficult but rewarding. Also, balancing everything together to make sure I took care of all of my responsibilities.

What are your plans for next year and beyond?

I applied to grad schools and eventually want to get a Ph.D. because I’m driven to teach. But first I want to get a job, possibly in Extension, where I can help better the industry and give back to growers.

Late blight lesion on tomato leaf. Click for larger view.

On May 18, New York State Agriculture Commissioner Darrel J. Aubertine alerted home gardeners and commercial growers of the potential introduction of late blight this growing season. “The exceptionally cool, damp spring we are experiencing throughout New York State this year heightens our concern for late blight,” the Commissioner said. (View news release.)

Cool wet conditions, coupled with the presence of the disease led to a quick and devastating spread of the disease in 2009. This season, late blight has already been detected at three sites in Michigan, Connecticut and Maine.

Gardeners and growers need to be on full alert to detect the disease early. Be sure to scout greenhouse and high tunnel tomatoes and early potatoes. If you think you may have late blight, contact your local Extension educator.

Knowing where late blight has been found is critical for making the best management decisions. A new national website USAblight is mapping reported outbreaks online. (Reports will not pinpoint your farm or garden, just the county.) View disease occurrence map.

Some resources to help you identify the disease and monitor the situation include:


10 tips for gardeners to beat late blight

So what can gardeners do to minimize late blight in their own gardens – as well as reduce the chance of spreading it to others?

Kill volunteer potatoes. Dig up, bag and trash any potato plants that pop up in your garden or compost pile. It may take repeated efforts to get them all.

Buy healthy tomato plants. Learn what late blight looks like. If you spot any infected plants while shopping, alert store management and your local Cooperative Extension office, and buy your plants somewhere else. Or you can grow your own plants. (Late blight isn’t spread on tomato seeds.) Start seed about 6 to 8 weeks before your last frost date.

Use certified seed potatoes. Don’t use leftovers from last year’s garden or table stock from the grocery store.

Keep plants dry. The late blight pathogen thrives in cool, wet weather. That’s because it requires moisture to infect plants, grows best when it’s cool, and clouds protect spores from lethal UV radiation when they are dispersed by wind. Even in absence of rain, the pathogen can infect plants if the relative humidity is 90 percent or more. If plants need watering, water the soil – not the foliage.

Be vigilant. Inspect plants at least once a week – more often if weather is cool and wet. Immediately remove and bag foliage you suspect might be infected. While late blight symptoms are distinctive – dark brown lesions on stems and leaves with white fungal-like growth developing under moist conditions – it’s possible to confuse it with other diseases. Your local Cooperative Extension office can help you with identification.

Act quickly. If symptoms continue despite removing infected foliage, consider removing plants entirely – sooner rather than later. “It is rarely possible to control late blight just by removing affected tissue,” says McGrath. “The longer you wait to remove plants, the more spores your garden sends to the wind to infect other gardens and farm fields.”

Sound the alert. If you find late blight in your garden, let your gardening neighbors and local Cooperative Extension staff know so they can warn others and be on the lookout for additional infestations. Make sure your neighbors know how to spot late blight in their own gardens.

Dispose of plants properly. To reduce disease spread, remove infected plants during the middle of a sunny day after leaves have dried, if possible. But don’t wait for these conditions. Seal plants in garbage bags and leave them in the sun for a few days to kill plants and the pathogen quickly before placing in the trash or burying underground or deep in a compost pile. Don’t just leave plants on the ground or on top of the compost pile where they will continue to be a source of spores until the plant tissue dies. With a large number of plants, you can build a pile on the ground and cover securely with a tarp until the plants die.

Keep an eye on other tomato-family plants. Some strains of late blight can infect other tomato-family plants, including weeds such as hairy nightshade and bittersweet nightshade. Control them early so that late blight on these plants doesn’t go unnoticed. Petunias and tomatillos are also vulnerable to attack.

Use fungicides with care. Fungicides can control late blight. (Chlorothalonil and copper-based products are both available to home gardeners.) But if you wait until late blight symptoms appear, it might be too late to rescue plants. For fungicides to work effectively on late blight requires a regular preventive spray schedule and thorough spray coverage. Follow all label directions, including use of respirator, waterproof gloves and protective eyewear.
