This is exactly what will happen to those who are planting onion transplants or sets in October or November with the hope of large onions next spring. Tissue analysis can often be used to detect nutrient deficiencies before they are visible.

Chateau flumioxazin is registered for up to three applications and a total of 3 ounces of product per acre per year. It may be applied with Prowl H2O, but not with Dual Magnum or Outlook because their solvents make Chateau more toxic to onion.

Chateau also has some pre-emergence and post-emergence activity on spotted spurge. Grasses can be controlled with Fusilade fluzifop-P , Poast sethoxydim or Select Max clethodim. The most critical early grass problem in onion is cover crop barley, which may grow too tall.

This often happens when heavy rains prevent timely herbicide applications. Barley should be planted at 0. It can grow past that stage rapidly during cool, wet conditions and adversely affect small onions, often causing stand and yield loss.

Preventing new weed germination and killing emerged weeds in the cotyledon stage is critical to success. A delayed preemergence application 10 to 20 days after seeding, before onion emergence allows many weeds to emerge, which are then killed with bromoxynil, which is added to the pendimethalin.

The primary weeds early in the season are ladysthumb, common purslane and redroot pigweed. The delayed preemergence pendimethalin plus bromoxynil should be applied just before onions emerge. Emerged onion plants may be killed by bromoxynil.

A few loops emerged from the soil surface is the latest safe stage to apply this treatment. Additional weeds that may germinate early include common chickweed, common lambsquarters, marsh yellowcress, shepherdspurse and Virginia pepperweed.

Common purslane is not killed by bromoxynil but can be controlled later with GoalTender. Ladysthumb and common lambsquarters that exceed 2 to 3 leaves often survive Goaltender application, so early kill with bromoxynil is important for season-long weed control. Delayed preemergence application of Prowl H2O also gives the inter-planted barley more time to become established.

The next preemergence application of pendimethalin should be made at the onion two leaf stage 2 LS. The delayed preemergence treatment maintains preemergence herbicide activity for one to two more weeks during the critical early growth stages of onion.

At the full 1 LS second leaf showing , oxyfluorfen GoalTender may be applied at up to 4 fl oz 0. Goal 2XL should not be used at the one leaf stage because it can injure the onions. This application is critical to maintain control of difficult weeds such as common lambsquarters, ladysthumb, marsh yellowcress and Virginia pepperweed.

In a cool, damp spring, common chickweed may germinate over several weeks and remain active throughout the season. Oxyfluorfen does not control common chickweed, so Nortron may be added to the preemergence or postemergence tank mix for control.

Chickweed normally dies out in a warm, dry year. If it persists, it can be controlled with a postemergence application of Starane Ultra or Chateau.

If the barley has not been killed yet, add a postemergence graminicide, such as Fusilade, Poast, or SelectMax, at the onion LS. At the onion 2 LS, apply pendimethalin or s-metolachlor Dual Magnum or dimethenamid-P Outlook.

The Chateau label allows tank mixing only with Prowl H2O. Dry onions are a crop that lends itself well to small-scale and part-time farming operations. Multiple markets exist for growers with small acreages, and the various colors and types of mature bulbs red, yellow, and white allow growers to find their market niche.

The term "dry onion" is used to distinguish them from green onions, which are pulled while the tops are still green and usually before a large bulb has formed. Many field operations, such as land preparation, planting, and harvesting, can be custom hired, and most of the equipment for planting and harvest can be used for other crops.

The common dry onion Allium cepa , a member of the Amaryllidaceae family, originated in mid-Asia in what is now northwestern India, Afghanistan, Tajikistan, and Uzbekistan. It was reported in the sixteenth century that onions were among the most common vegetables used at that time.

They occurred in red and white varieties and were sweet, strong, or intermediate in flavor. The onion was introduced by the Spanish into the West Indies soon after their discovery.

From there, onions spread to all parts of the Americas and were grown by the earliest colonists and soon afterward by Native Americans.

Relatives of onions include garlic, leek, chives, Welsh onion, and shallots. The United States harvests over , acres and produces almost 7 billion pounds of onions annually. In , the Northeast produced over 8, acres of onions on over 3, farms. Fresh-market onions are available in the northeastern United States from the first of July to the end of October.

They are traditionally sold loose in bulk containers or in mesh bags of various weights. Several marketing alternatives are available to the onion grower: wholesale markets, cooperatives, local retailers, and roadside stands, farmers markets, community-supported agriculture CSA , pick-your-own operations, and processing firms.

When planning production, first consider your ability and access to market. You should conduct some market research—growers often overestimate their ability to sell in a given market. Production of less than one acre of many vegetable crops is typical for most growers.

In wholesale marketing, producers often contract with shippers to market and ship the onions for a predetermined price. If you do not use a contractor and ship your onions to a wholesale market yourself, your product will be subject to the greatest price fluctuations. Marketing cooperatives generally use a daily pooled cost and price, which spreads price fluctuations over all participating producers.

Local retailers are another possible market, but you must take the time to contact produce managers and provide good-quality onions when stores require them. Depending on your location, processors may or may not be a marketing option.

Processors are less likely to contract with small-acreage growers those with fewer than 5 acres. For more information on marketing, consult "Agricultural Alternatives: Fruit and Vegetable Marketing for Small-Scale and Part-Time Growers. Retail marketing options include roadside stands either your own or another grower's , farmers markets, CSA, and pick-your-own operations.

These options can provide opportunities to receive higher-than-wholesale prices for your onions, but you may have some additional expenses for advertising, building and maintaining a facility, and providing service to your customers.

With pick-your-own operations, you save on harvest costs, but you must be willing to accept some waste. Farmers markets are another retail option, but you should contact the markets well in advance of the marketing season to be sure space is available and to find out what requirements you must follow.

For more information about roadside markets, see "Agricultural Alternatives: Developing a Roadside Farm Market. Onions should be grown on friable soils, which contain high amounts of organic matter and have good water infiltration rates and good moisture-holding capacity.

The soil should not be compacted, and the pH should be 5. Sandy loams and muck soils are often used for onion production. For sweet Spanish onion production, soils with low sulfur levels below 40 ppm are recommended.

Variety Selection Bulbing of onions is primarily induced by photoperiod, or day length. Both long-day and intermediate-day onion varieties are recommended for the northeastern United States Table 1. Onions are also classified by skin color red, white, brown, or yellow , taste sweet or pungent , and bulb shape round, flat, or globe.

Planting and Fertilization Onions can be started as transplants or sets. Transplants are seeded in the greenhouse 10 to 12 weeks prior to planting in the field. Because onions are a cool-season crop, they can be transplanted as early as mid-March.

When producing transplants in the greenhouse, the plant tops should be trimmed to a height of 4 inches to produce a stout, sturdy transplant.

Growers generally plant 75, to , onions per acre in single rows with 2 inches between plants in the row and 24 inches between rows. For large sweet or Spanish onions, the in-row spacing would be 4 to 6 inches between plants. If you are not limited by equipment space restrictions, multiple up to four rows of onions can be planted on raised beds covered with black plastic mulch.

In this case, two drip tapes are placed 2 inches beneath the soil to facilitate production and harvest operations. Providing your onions with drip irrigation ensures optimum plant growth and yields and provides the option to apply injection-based fertilizer during the growing season.

For more information on drip irrigation, consult " Agricultural Alternatives: Drip Irrigation for Vegetable Production. Fertilizer application rates should be based on an annual soil test.

If you are unable to conduct a test including a test for calcium , the recommended N-P-K nitrogen, phosphorus, potassium application rates are pounds per acre banded at planting or pounds per acre broadcast prior to planting.

For sweet onions, a spring application early May of calcium or potassium nitrate should be side-dressed at pounds per acre. Weed management can be achieved with herbicides, cultivation, and a good crop-rotation system.

Several preplant and postemergence herbicides are available for onions, depending on the specific weed problem and the stage of onion growth. If infestation levels are mild, early cultivation can minimize weed problems.

Insects can be a major problem in onion production. Onion maggots and thrips have the potential to reduce or destroy crops in any given year. Allium leafminer is a new invasive insect that is being found increasingly in onions in Pennsylvania.

Monitoring insect populations will help you determine when you should use pesticides and how often you should spray. Several onion diseases can cause crop losses, especially downy mildew, purple blotch, and white rot.

Many of these diseases can be prevented by using a good crop-rotation system, high-quality soil with good air drainage, and disease-resistant onion varieties.

Many of the pesticides necessary for onion production are restricted-use pesticides and require a pesticide license to purchase. Pesticide applicator tests are usually administered at extension offices; contact your local office for dates and times.

When using any pesticides in your enterprise, remember to follow all label recommendations regarding application rates and personal protection equipment requirements. Also remember that worker protection standards apply to both owner and employees.

Most dry onions are usually harvested when one-third to one-half of the tops have fallen over.

Onions have a shallow, non-aggressive, fibrous root system, and weed competition early in the growing season can significantly reduce yield. Weeds can also interfere with chemical sprays and harvest operations and exacerbate the environmental conditions favorable for foliar disease development by decreasing air movement within the canopy. Weed control in onion fields starts in the fall after harvest of rotational crops and is mainly achieved through a combination of chemical, cultural and mechanical weed control strategies. After crop harvest in the fall, pay close attention to the weed species present in your field. If there are many perennial weeds, then it is the best time to apply glyphosate. Onion field management
