Lorsban is Banned: How to Control Cabbage Maggot in Brassicas Now?
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
Cabbage maggot (CM) feeds on brassica seedlings by tunneling into the stem of the plant just below the soil line. Their feeding can result in unsightly and unmarketable produce in the case of root brassicas like turnips, and in stunting, reduced stand, and reduced yield in head and stem brassicas like cabbage and broccoli. Lorsban and other formulations containing the active ingredient chlorpyrifos were the first line of defense for control of cabbage maggot in several brassica crops, because 1) at ~$10 per acre, it was affordable, and 2) it was easy to apply and avoided worker exposure as a directed spray at the base of the plant.
Unfortunately, Lorsban and all of its generic products for food and feed uses were banned in New York as of July 31, 2021, and in the United States as of February 28, 2022. In the absence of Lorsban and other chlorpyrifos-containing insecticides, NY brassica growers have 6 products belonging to 4 chemical classes available to manage cabbage maggot. This article provides our "2022 Top Picks" to use instead of Lorsban plus results of Cornell research trial results related to application method, rate, and cabbage maggot control.

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.
Video: New York State Produce Auctions
Currently, there are 8 produce auctions in New York State. These auctions are aggregation points that allow local farmers to sell their produce in wholesale lots to buyers from across the region. To document the economic impact of produce auctions on agriculture, local businesses, family farms, and produce buyers, the Cornell Vegetable Program worked with Harvest New York to survey top sellers and buyers.
A new Cornell Vegetable Program video shares general information about produce auctions, how buyers and sellers use the auctions to expand their businesses, and how local communities benefit from them.
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.
Crop Cooling and Storage
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
On-Farm Cold Storage of Fall-Harvested Fruit and Vegetable Crops is an in-depth look at the planning and designing cooling for late season and winter storage but it also is useful for general cooling as well. This was written by Scott Sanford, Distinguished Outreach Specialist, UW-Extension, and John Hendrickson, Outreach Program Manager, Center for Integrated Agricultural Systems, University of Wisconsin-Madison.
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.
