Broccoli
Broccoli is grown on an estimated 800 acres throughout New York State. Multiple plantings are typically grown along with other Cole crops such as cauliflower, cabbage and kale on small-scale diversified vegetable farms. Broccoli is predominantly grown from transplants set in April and May for a spring crop and in late June through August for a fall crop. Broccoli that is harvested in July and early August tends to have very high cull rates due to abnormalities caused by heat stress. Broccoli is cut during the cooler part of the day and sold as soon after harvest as possible, as it does not store well.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.

Sprouting Broccoli and Mini Cabbages for Early Spring High Tunnel Harvests
Elisabeth Hodgdon, Vegetable Specialist
Eastern New York Commercial Horticulture
Providing a diverse offering of vegetables for early spring CSA shares and markets can be a challenge. Offerings usually consists of leftover storage root crops, salad greens, and radishes. Due to their cold tolerance and quick growth, brassicas are promising crops for cool spring high tunnel environments. Last spring, we trialed two varieties of sprouting broccoli and four varieties of small cabbages at the Cornell Willsboro Research Farm to develop seeding date and variety recommendations for our region. We harvested fresh broccoli and tender cabbages in mid-May—excellent timing for the start up of farmers market season.
Broccoli Grower Survey

Our colleagues Christy Hoepting and Chris Smart are excited to be part of a 4-year USDA multi-state project on Alternaria leaf spot and head rot in broccoli, which is starting this growing season. This "Control Alt Delete" project will utilize genomics, population genetics and fungicide resistance profiling to understand the Alternaria pathogen(s) that attack brassicas - "get to know the enemy" so-to-speak. Plus, the project aims to design practical and economically sound strategies to limit losses from Alternaria, which will be relevant to all brassica crops.

Brassica Project 2018
Amy Ivy, Vegetable Specialist
Eastern New York Commercial Horticulture
Our New England colleagues have launched a regional project related Brassicas, and New York growers and colleagues are welcome and encouraged to join in.
The Brassica Pest Collaborative is intended as a place where growers and extension folks can talk to each other and share observations and questions throughout the season so feel welcome to join and contribute all things Brassica! They are also looking for more growers to join that list and to sign up as collaborators who will implement a practice and collect some scouting records to help them assess efficacy of given practices on real farms. Growers can sign up by emailing brassicapest@umass.edu and include information about your farm, pest issue and what strategy you would like to try to implement.

O-zone Injury on Vegetables
Crystal Stewart-Courtens, 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.
