Cauliflower

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

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

New Crop Rotation Recommendations for Swede Midge

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.

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

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

Extending the Harvest Season with Fall Production

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.

Announcements

Winter Cover Cropping in High Tunnels

Cornell Cooperative Extension is researching cover crops for high tunnel growers to better manage fertility and improve soil health. Our work has shown that winter cover cropping in high tunnels has the potential to add organic matter, improve soil structure, support microbial activity, and help with nutrient management by scavenging leftover nitrogen and/or fixing nitrogen. This publication, Management Practices for High Organic Matter Soils: Winter Cover Cropping in High Tunnels, shares best practices for winter cover cropping in high tunnels including species selection, planting rates and dates, termination, and cultural management considerations.

Laser Scarecrows to Deter Birds in Sweet Corn

Are you considering the use of a laser scarecrow to deter birds on your farm? Cornell Cooperative Extension and the University of Rhode Island teamed up to test a research laser scarecrow on sweet corn farms.

A laser scarecrow is a device that has one or more laser modules connected to motors. The specifications of the lasers are optimized to the color and motion sensitivity of bird's eyes. When laser beams move across a field, birds become frightened and attempt to move away from the perceived threat. Light from the laser covers an area quickly and moves through the canopy without causing injury to the crop. Research demonstrates that birds do not readily become habituated to the laser.

A laser scarecrow used as the sole deterrent typically results in a significant reduction in crop damage. Combined with an auditory device, damage can be reduced even more. When used as part of an integrated management program for bird control that utilizes habitat management and multiple scare tactics, laser scarecrows can be useful tools for growers of multiple crops. All scare tactics must be deployed before birds find the field. The effectiveness of lasers depends on multiple factors such as bird species, bird populations, habitat and food availability. Lasers are not effective at deterring deer, racoons, coyotes or other mammals.

To learn more, the Laser Scarecrows to Deter Birds in Sweet Corn and Other High-Value Agricultural Crops fact sheet provides background information, research data, FAQs, and Advantages/Limitations on laser scarecrows.

NY Urban Farms Pest Management Fact Sheet Series

Cornell Cooperative Extension has partnered with dozens of urban farms across New York State to demonstrate and evaluate sustainable pest management strategies. Together with farmers, we found success using control methods that prevent or reduce crop losses through exclusion strategies, crop timing, host resistance, the introduction of beneficial organisms, and more. Regardless of management strategy used, common requirements for success include a knowledge of the pest and disease complex, preventative deployment and commitment to the process. The New York Urban Farms Sustainable Pest Management Fact Sheet Series includes case studies highlighting pest management techniques that New York urban farms have found valuable.

NYS Urban Growers Pest Management Needs Assessment

As part of a multi-year project exploring non-spray pest management options that are economically and environmentally sustainable for urban farms, we conducted a needs assessment with urban growers across New York State. The New York State Urban Growers Pest Management Needs Assessment presents findings on current pest management practices, challenges, and topics of future interest.
