Apples

Apples The 2012 USDA Census revealed that the 16 counties comprising the Eastern NY Commercial Horticulture program had over 12,500 acres devoted to apple production. The lower Hudson Valley region and the Lake Champlain region are two of the largest and most important apple production areas in New York state which ranks second in the nation for apple production and first in the country for canned apple products, although much of that crop is produced in western NY.

Apples are thought to have originated between the Caspian and the Black Seas and proof of humansí enjoyment of apples traces back at least 750,000 years. Early settlers brought apple seeds with them to the United States. Records indicate that apples were grown in New England as early as 1630. John Chapman, also known as Johnny Appleseed, along with many other traders, missionaries and Native Americans, were responsible for extensive apple tree plantings in the Midwest and beyond.

Apples are one of the most valuable fruit crops in the United States. The 9.0 billion pound U.S. 2012 apple crop was valued at nearly $3.1 billion. Apples are the second most consumed fruit (fresh and processed uses combined), following oranges. The average person consumes 44 pounds of apple products annually.

Over the last 20 years, Cornell research and extension projects have helped growers increase yields and fruit quality by increasing tree densities and improving labor efficiency. We estimate that profitability of new high density orchards is 100 to 300% greater than the traditional low-density orchards.

In 2013, Cornell University announced the introduction of two new apple varieties, SnapDragon and RubyFrost, developed through a managed release partnership with the New York Apple Growers (NYAG). The income generated through this partnership is used to market the new varieties and support Cornellís apple-breeding program.

Best Management Practices for High Tunnel Nutrition and Soil Health

September 13, 2017
5:00 PM - 6:30 PM
Poughkeepsie, NY

Soil tests, foliar tests, foliar feeds, fertigation, managing for yield...long term soil health in a high tunnel isn't a simple process. It can have a lot of components and require a fair amount of analysis. Cornell Cooperative Extension, partnering with NOFA-NY in a New York Farm Viability Institute funded project, have been working to identify long-term soil health and fertility best management practices. We will share what has been learned.

Announcements

Welcome Jim Meyers: New Viticulture Specialist!

Jim has been working with wine grapes for 10 years, first as a Viticulture Ph.D. student at Cornell then as a Research Associate. Prior to coming to Cornell, Jim studied Chemistry and Biology (B.S. West Chester University of Pennsylvania), Computer Science (M.S. Brown University), and had a successful career as software technology entrepreneur. This background is reflected in his viticultural research which has focused on computational tools for mapping canopy and vineyard variability, quantifying relationships between variability and fruit chemistry, and optimizing efficiency of vineyard operations. As an Extension Associate, Jim will continue some of these research activities while also looking for new projects that provide targeted benefits to appellations in Eastern New York. Jim will kick off his new appointment by visiting growers at their vineyards to gather first hand knowledge of the sites and to discuss vineyard operations, goals, and challenges. Building a complete catalog of vineyards in a territory that runs 300 miles along the Route 9 corridor may take a little while, but Jim feels that the effort will lay a solid foundation for future program activities while also clearly differentiating the needs of each appellation.


New Resources for Berry Crops

Berry Crop Diagnostics Tool - Much information exists on controlling plant pests and problems, but one must first identify the cause before intervention can occur. This diagnostic tool was developed to assist the student, grower, and extension educator in identifying potential causes of plant problems in berry crops

White Rot Update

NOW AVAILABLE: White Rot Fact Sheet: Click Here

Earlier in June I sent a garlic sample to the diagnostic lab hoping that I was wrong. The sample was covered in small black sclerotia, the size of poppy seeds, and white fungal hyphae crept up the stem. The results, unfortunately, matched the field diagnosis: White Rot. Within a couple days additional calls came from up and down the Hudson Valley as well as one in Western NY with similar suspicions. These samples have also gone to the lab for verification, but it looks like the latest pest to move back into the state is this nasty fungus. 

White Rot, Sclerotinia cepivorum, decimated the onion industry in New York in the 1930's before being eradicated through careful management. More recently, in 2003, it infected 10,000 acres of garlic in California, leading to the abandonment of some garlic fields and adoption of strict containment rules. White rot has been confirmed in Northeastern states over the last decade as well, with New York being one of the last to discover the disease.

The primary reason that White Rot is such a concern is because the sclerotia, or reproductive structures, can remain dormant in the soil for up to 40 years, attacking any allium crop planted into the soil under favorable conditions. This spring was ideal for infection due to the period of cool, moist weather we had. Optimal temperature for infection is 60-65 degrees F, but infection can occur anywhere from 50-75 degrees F.
Once garlic has white rot, it generally declines rapidly. Leaves will yellow and the plant will wilt, not unlike a severe fusarium infection. However, unlike with fusarium, white rot infected bulbs are covered in black sclerotia and white fungus. To add to the confusion, another disease CAN look similar. Botrytis also causes black sclerotia and white fungal growth. However, Botrytis sclerotia are quite large, often larger than a pencil eraser.

So, what do we do now? We're still working on long-term management strategies, but the most important steps to take now are vigilance when culling (look at the plants you are pulling for symptoms like you see in this article, and if they are present, call us to take a sample and have the disease verified) and, if you see anything suspicious, reduction of movement of inoculum. The main ways diseases get moved around are by dumping culls (compost, field edges, etc) and my moving soil on equipment. Throw away your culls, and wash equipment that may have come in contact with suspicious garlic or the soil it is growing in. Everything from cultivation equipment to harvest bins should be cleaned. 

We will keep learning about this disease and will keep sending out information, particularly to help you make decisions about what to sell and buy. For now, remember that the west coast has learned to manage the disease, and we will too. -Crystal Stewart, ENYCHP
