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 humans’ 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 Cornell’s apple-breeding program.

Strategies for Dealing with Pesky Perennial Weeds
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Perennial weeds can be particularly difficult to manage in the apple orchard. These plants are defined as being able to live for more than two years, which is due to their abilities to produce large root systems or other underground storage structures, such as bulbs, tubers, and rhizomes. These structures facilitate the spread of perennials in orchards, although many species also produce seed that support dispersal.

It's looking like a difficult storage year for Hudson Valley Honeycrisp Producers
Reports are starting to filter in of excessive Honeycrisp cullage out of storage this season. The predominant defect reported is bitter pit, a surprise to some following observations that this season's crop appeared relatively clean at harvest. Our ENYCHP tree fruit team is currently in the 3rd year of our comprehensive Honeycrisp/Bitter Pit survey study, and our results to date shed some light on how 2018 compares to '16 and '17.
2018 Northern NY Trap Data and Pest Exclusion with Hail Netting
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
During the 2018 growing season, we maintained an IPM trapping network in Northern New York, ranging from Chazy in Northern Clinton County to Rexford in Southern Saratoga County. From May through mid-September, we sent weekly e-alerts of our trap counts for oriental fruit moth, codling moth, obliquebanded leafroller, and apple maggot. Now that harvest is winding down, I would like to review this season's pest trends, and discuss what we observed from our hail netting trials in the Champlain Valley.
Marssonina Leaf Blotch of Apple - A Growing Problem in South-Eastern New York
Dan Donahue, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Excessive rain in New York and the rest of the Eastern US experienced in the second half of both the 2017 and 2018 growing seasons favored the development of Marssonina Leaf Blotch (MLB), a disease caused by Marssonina coronaria (sexual stage Diplocarpon mali). In early September 2017, in the lower-Hudson Valley and south NY we found MLB late in the summer in more than several apple orchards on Mutsu, Honeycrisp, NY-1 (SnapDragon), NY-2 (RubyFrost), Gala, Red Delicious, Golden Delicious, Pristine, Grimes Golden, Northern Spy, Stayman Winesap, Tompkins King, and others. The alarming outcome was defoliation of lower part of the tree crowns, especially where moisture due to heavy dew or sprinkler irrigation was present up until midday.

Hail Netting: Is It Right for Your Farm?
Elizabeth Higgins, Business Management Specialist
Eastern New York Commercial Horticulture
Increasingly tree fruit growers in NYS are looking at hail netting as a tool for reducing the impact of hail in their orchards. Hail netting is already widespread in Australia, Europe and is increasing in popularity in Washington State. Netting is used in those places, not only to protect the fruit from hail, but also from sun damage, and insect/pest damage and to increase the quality of the fruit crop. While hail netting seems to have promise, the growing conditions for tree fruit in New York are not the same as Australia, Europe and Washington. The Cornell Cooperative Extension Lake Ontario Fruit Team has recently received a grant to study hail netting in New York and its impact on pests and disease, yields, and quality of the fruit and to better understand the costs and labor needs for managing a hail netting system in a New York orchard.
Increasing Your Wild Orchard Pollinators
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Last week while we were nearing petal fall in the Champlain Valley, a grower and I were discussing when he ought to take his honey bees out of the orchard, which led us to discussing the role wild bees are playing in his orchard. These wild bees help pollinate our crop every year, so I think it is worth reviewing some of the different kinds of bees we can expect to see at bloom, and what we can do to encourage their visits.
The CCE Apple Decline Survey Has Been Extended Through the Summer of 2018
Dan Donahue, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Cornell Extension Specialists are being asked with increasing frequency to investigate both chronic decline and rapid collapse of apple trees in young, high-density plantings in all regions of New York State. Symptoms of chronic decline can include poor growth, off color foliage, and a generally unthrifty appearance that worsens over several years. The death of an (apparently) previously healthy tree over the course of just a few weeks has been termed Rapid Apple Decline (RAD). While the symptoms of chronic decline are subtler in some cases, RAD is eye-catching. Afflicted trees appear to "burn up" mid-summer after having set and sized a normal crop load. RAD may be a subset of the chronic decline condition or a completely different problem; causation is unknown at this time.

Proper Disposal of Pesticide Containers
Dan Donahue, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Tree fruit producers generate substantial quantities of empty pesticide containers over the course of the growing season. Back in the "old days", paper bags found their way into a burn barrel, and plastic jugs into a landfill. Neither option is viable today, so what to do? Landfall disposal is still an option for some types of pesticide containers, and recycling is available for others, but first, here's what's legal in New York State.
Weed Management in Newly Planted Orchards
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Early weed control is a critical component of establishing a new planting. Newly planted fruit trees compete poorly against fast growing weeds for water and nutrients. This competition can severely limit a new block's growth, which can ultimately reduce potential yields in the third year by 50 percent. Weeds also harbor insects and diseases, provide habitat for rodents, and can serve as hosts for viruses, further complicating effective orchard management.

Bird Damage in Tree Fruits
Anne Mills, Field Technician
Eastern New York Commercial Horticulture
Frugivorous birds impose significant costs on tree fruit growers through direct consumption of fruit and
grower efforts to manage birds.We documented factors that influenced tree fruit bird damage from 2012
through 2014 with a coordinated field study in Michigan, New York, and Washington. For sweet cherries,
percent bird damage was higher in 2012 compared to 2013 and 2014, in Michigan and New York
compared toWashington, and in blocks with more edges adjacent to non-sweet cherry land-cover types.
These patterns appeared to be associated with fruit abundance patterns; 2012 was a particularly lowyield
year for tree fruits in Michigan and New York and percent bird damage was high. In addition,
percent bird damage to sweet and tart cherries in Michigan was higher in landscapes with low to
moderate forest cover compared to higher forest cover landscapes. 'Honeycrisp' apple blocks under
utility wires were marginally more likely to have greater bird damage compared to blocks without wires.
We recommend growers prepare bird management plans that consider the spatial distribution of fruit
and non-fruit areas of the farm. Growers should generally expect to invest more in bird management in
low-yield years, in blocks isolated from other blocks of the same crop, and in blocks where trees can
provide entry to the crop for frugivorous birds.
