Fortunately, recent genetic breakthroughs have overcome broccoli's susceptibility to heat stress and broccoli growers in New York look forward to the availability of new varieties adapted to the hot and humid summers of the Northeastern United States. Cornell University is leading an ambitious effort to develop a $100 million broccoli industry in the Eastern United States. Below you will find educational information and results of our research trials.
Organic Production Guides
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
Organic Production Guides for fruits, vegetables and dairy are available through the NYS Integrated Pest Management (IPM) program. They outline general practices for growing vegetable and fruit crops using organic integrated pest management techniques.
2010 Broccoli Variety Evaluation
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
The 2010 Broccoli Variety Trail consisted of 27 entries from 7 seed companies. Industry standards included Diplomat, Gypsy, Green Magic, Imperial and Windsor. Two varieties, Major and Bl 10, were included to evaluate heat tolerance.

O-zone Injury on Vegetables
Crystal Stewart, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
Hot, humid weather with stagnant air masses may lead to ozone damage on crops. Ozone warnings were recently issued for much of New York. These warnings are intended for people with respiratory problems and let them know they should limit their outdoor activity and try to stay as much as possible in air-conditioned locations. These warning are also a good indicator that ozone damage may occur in plants.

Grape Specialist Hiring in Eastern New YorkEastern NY Grape Industry Growth Prompts Marketing Initiatives, Specialist Hiring
Eastern New York grape and wine industry growth is sparking innovative marketing initiatives and the hiring of a new regional grape specialist.
The "October 2016 Grape Production in the Eastern New York Commercial Horticulture Region" report by Elizabeth Higgins, business management specialist, Hudson Valley Lab, Highland, NY, quantifies industry growth as:
. a 34 percent increase in the number of grape-growing operations 2007-2012 with a 50 percent increase in grape acres,
. the 2001-2012 doubling of grape production acres in Ulster, Columbia, Dutchess and Orange counties,
. 2001-2012 growth from nearly zero to 100-plus grape acres in Clinton, Essex, Saratoga and Washington counties, and
. 108 wineries affiliated with local grape production; with new wineries expected.
White Rot Update
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
