Cauliflower
About 500 acres of cauliflower are planted in New York annually. Cauliflower is a member of the Brassicaceae family which includes cabbage, broccoli and Brussels sprouts. All of these crops do well in the climate of New York, but cauliflower is produced as a fall crop to avoid summer heat which can cause heads to become soft and over-mature quickly. Heads maturing in hot weather (over 80 degrees F) can exhibit riciness, leafy heads, off color, loose heads or poor wrapper leaf development. Cauliflower is typically harvested from August through November in New York. Most cruciferous crops have similar cultural requirements and are susceptible to a common set of insects and diseases.Recently, orange and purple varieties are becoming more common along with the traditional white forms.

Cabbage Maggot Control in Brassicas, 2024
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
Since the brassica industry's go-to for cheap, easy and effective control of cabbage maggot, Lorsban along with its generic products (active ingredient chlorpyrifos) was banned in 2021, Brian Nault (Cornell Entomology) and Cornell Vegetable Program Specialist Christy Hoepting have been conducting cabbage maggot trials annually from 2021 to 2023 in search of an effective and affordable alternative. Read our key findings and the 2024 Cornell "Cheat Sheet" for Insecticide Options for Cabbage Maggot in Brassicas in New York.
New Crop Rotation Recommendations for Swede Midge
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
New Cornell research has demonstrated that brassica crop rotations of 500 ft (down from 3000 ft) and 3 months (down from 3 years) could effectively "crash" a swede midge population when fields are secluded from each other, making crop rotation a much more feasible strategy for small farms. A new fact sheet details the new crop rotation recommendations and provides information on the pest's life cycle, biology, and crop preferences in addition to real-world examples of crop rotation. The crop rotation strategies were developed to serve the needs of small organic farmers, but have utility for conventional farmers as well.
Growing for Wholesale: Grading and Packing Guidelines by Crop
Grading and packing guidelines are now available for 18 commonly grown specialty crops in NYS: romaine lettuce, acorn squash, broccoli crowns, Brussels sprouts, sweet corn, green peppers, cucumbers, green cabbage, red cabbage, savoy cabbage, cauliflower, eggplant, green beans, jalapenos, poblanos, Hungarian hot peppers, summer squash, and zucchini.
Growing for Wholesale: Vegetable Grading/Sizing Templates
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
To further assist farmers looking to sell into the wholesale markets, the Cornell Vegetable Program has put together some helpful tools. The tools provided here consist of a color photo guide highlighting the grades of some of the most common vegetables grown for wholesale market in WNY. To aid in the visualization of the grading sizes, the templates are available here for you to print off. These are scaled to size and can be used to create sizing templates to be used by workers on the wash and pack lines.
Video: Swede Midge
Swede midge is an invasive insect pest that is threatening the viability of broccoli, cauliflower, cabbage, Brussels sprouts, kale, kohlrabi and turnip production within the Cornell Vegetable Program region and throughout the Northeastern US. This short video will provide you with some general information about this pest and how to scout for it in your Brassicas.
Video: Flea Beetles
Flea beetles are a common vegetable pest affecting peppers, cucurbits, sweet potato, potato, peas, beans, beets, tomato, corn, turnip, pumpkin, melon, eggplant, and others. This short video gives you some general information about this pest.
Cold Storage Chart and Reference Guide to Commercial Vegetable Storage
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
Commercial vegetable growers will find a Cold Storage Chart by crop type with temperature and relative humidity recommendations. The maximum number of weeks that the crop can be held under ideal conditions is provided as well.
Adapted from the USDA Bulletin #66, The Commercial Storage of Fruits, Vegetables, and Florist and Nursery Stock, growers will find information on quality, grading, sizes, and packaging, chilling and storage, and post-harvest pathology of vegetables.
Video: Produce Washing Stations - How to Use a Germicidal Bleach
Good Agricultural Practices or GAPs are the steps taken in produce packing areas to reduce microbial contamination. One area where reducing micro contamination is critical is in the washing and cleaning of produce. This video shows you a set of standard operating procedures for using a germicidal bleach in a produce washing station. Learn what supplies are required and how to calculate the amount of germicidal bleach needed to sanitize the water.
Video: Farm Food Safety as if Someone's Life Depended On It
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
This video is an overview of Good Agricultural Practices (GAPs) through on-farm risk assessment. Cornell Cooperative Extension, along with the National GAPs Program and the New York State Department of Agriculture and Markets, has developed and implemented a nationally-recognized training program in GAPs to prepare New York growers for the marketplace's increased vigilance in food safety. You can learn more about that program through this video, as well as updates on the Food Safety Modernization Act (FSMA), and economic information on the implementation of GAPs collected from growers through extensive interviews.
Extending the Harvest Season with Fall Production
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
Late season production starts in mid spring. For a successful crop, start with a detailed plan. Designate an area specific for late season production so that management can take place in one spot rather than all over the farm. This will make cultivation, pest management, using row cover, and harvesting more efficient to manage.
