Garlic
Garlic production has increased significantly in New York over the last few decades, and garlic is now considered to be an important niche crop. In 1992, only 11 acres of garlic were reported in New York, but by 1997 the number grew to 153 acres and by 2007 it again doubled to 306 acres. Garlic is currently estimated to be a $20 million dollar crop. New York is the fifth largest garlic producing state in the country, and ten percent of all New York vegetable farms report growing garlic. That is a higher percentage of growers than for broccoli, cabbage, carrots, lettuce, or onions.Garlic is sold at farmers' markets from mid-summer to the fall throughout the state. Garlic is also sold at festivals which take place throughout the Northeast from August through October. New York's largest festival is in Saugerties, in September. Festivals are important outlets for growers and important agrotourism events for the cities that host them.
Varieties of garlic grown in New York tend to be different from those you will find in the grocery store. New York is known for excellent 'hardneck' garlic, which has a hard stalk running through the center of the bulb. The flavor of our hardneck garlic is often considered to be stronger and more unique than the flavor of 'softneck' varieties found in the grocery store and grown primarily on the West Coast or in China.

Allium Leafminer Spring Flight Update
Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture
The spring flight of the new invasive insect pest, the allium leafminer, is coming to an end. However, the larval stage of the pest will remain active for a couple of more weeks and can cause significant damage to garlic, scallions, onions, and chives. Read more about how to continue to protect your spring allium crops and how to prepare for the fall flight.

Lookout for Leek Moth
Amy Ivy, Vegetable Specialist
Eastern New York Commercial Horticulture
Leek moth adults emerge in mid April to mate and lay eggs. This year the first moths were caught in Essex on April 21. The larvae will hatch in a couple of weeks and can do considerable damage to garlic scapes so this is a good first place to look when scouting.
Be cautious when buying and selling onion transplants between growers in the infested areas. We have seen leek moth appear in new locations when infested plants were brought in from farms to the north.
Be on the Lookout for Southern Blight
Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture
Southern Blight (Sclerotium rolfsii) was found on golden storage beets this winter in Dutchess County. The fungal pathogen is fairly new to New York and poses a threat to a wide range of vegetable crops. Early detection and proper diagnosis are key to managing this disease.
Early Season Garlic Fertility

Eastern New York Commercial Horticulture
The window for fertilizing garlic this spring is closing over the next couple weeks. Apply up to 50 lbs/A of quick-release nitrogen in a banded application to boost yields. Read on for more information about how microbes are releasing the N already found in the soil organic matter and in fall fertilizer applications.
Allium Leafminer Active in Southern Pennsylvania
Teresa Rusinek, Vegetable Specialist
Eastern New York Commercial Horticulture
A new invasive insect pest in the Northeast known as the Allium leafminer (ALM), Phytomyza gymnostoma, damages crops in the Allium genus (e.g., onion, garlic, leek, scallions, shallots, and chives) and is considered a major economic threat to Allium growers. Originally from Europe, ALM was first detected in Lancaster County, Pennsylvania in December of 2015 and in New Jersey and New York in 2016. As of fall 2017, ALM activity has been confirmed throughout eastern Pennsylvania, New Jersey, Delaware, southeastern New York as well as Thompkins and Suffolk counties.

White Rot Fact Sheet
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
White rot is a worldwide problem in allium production, and has resurfaced in the New York garlic industry after a long period of eradication. Positive samples were collected in 2016 from the Hudson Valley, Central and Western New York, indicating that the disease is widespread. As with other soilborne diseases, white rot can be persistent and devastating. However, careful management can reduce inoculum, and because the disease is spread by seed and soil, it is also possible to prevent its spread into uninfested fields.

During 2016 and 2017 garlic growers can submit samples for fusarium testing free of charge, courtesy of a SARE grant. Please fill out the form completely when submitting, as the information collected helps us to understand the impact of this disease on the industry.
White Rot Update
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
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. It is now confirmed in the ENYCHP region.

Leek Moth Control and Information
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
Leek Moth was detected in four home gardens in Plattsburg, NY in 2009. It was first detected in Ontario, Canada in 1997 where it has become problematic especially to small-scale, organic growers in eastern Ontario and to commercial producers in western Quebec, who have limited insecticides available to them.
Leek Moth continues its spread to more farms and gardens across the U.S., a new comprehensive website is available to aid in the identification and management of this pest. This Cornell website features maps of the distribution of leek moth, protocols on insect monitoring and identification, best management practices for farms and home gardens, a photo gallery of damage symptoms and a comprehensive resource section.
