|Arthropod Pest Management Research on Vegetables in Virginia – 2010||
This booklet contains arthropod pest management research conducted on vegetable crops in eastern Virginia in 2010. If not noted otherwise in the individual reports, all research was conducted at the Virginia Tech Eastern Shore Agricultural Research and Extension Center near Painter, VA and at the Hampton Roads Agricultural Research and Extension Center in Virginia Beach, VA. All plots were maintained according to standard commercial practices. Soil type at the ESAREC is a Bojac Sandy Loam. Soil type at the HRAREC is tetotum loam (average pH: 5.7). Most of the research involves field evaluations of federally‐labeled and experimental insecticides. Much of the information presented herein will be published in a similar format in Arthropod Management Tests: 2011, vol. 36 (Entomological Society of America). We hope that this information will be of value to those interested in insect pest management on vegetable crops, and we wish to make the information accessible. All information, however, is for informational purposes only. Because most of the data from the studies are based on a single season’s environmental conditions, it is requested that the data not be published, reproduced, or otherwise taken out of context without the permission of the authors. The authors neither endorse any of the products in these reports nor discriminate against others. Additionally, some of the products evaluated are not commercially available and/or not labeled for use on the crop(s) in which they were used.

Two species of asparagus beetles are found in Virginia, the asparagus beetle, Crioceris asparagi (L.), and the spotted asparagus beetle Crioceris duodecimpunctata (L.). Adults of the asparagus beetle are 1/4 inch (6.25 mm) long, metallic blue to black, and have wing covers with three or four white spots and reddish margins. The thorax is red and usually marked with two black spots. The spotted asparagus beetle is about 1/3 inch (8.3 mm) long and orange with 12 spots on its wing covers. Larvae of both are olive green to dark gray with a black heads and legs. Larvae measure about 6/100 inch (1.5 mm) at hatching, and as they develop they become plump and attain a length of about 1/3 inch (8 mm). Both have eggs that are approximately 4/100 inch (1 mm) long, oblong, shiny, black,\ and are attached by one end to asparagus spears.

|Asparagus Beetles on Asparagus||
The asparagus beetle is a sporadic pest that can be aggravating for asparagus growers throughout Virginia. The shoot damage not only reduces the quality of the spears but this beetle is also unique in the pest world, as it is an insect that is controlled because the eggs laid on the shoots is objectionable to consumers. With a little background on this pest most growers are able develop an effective pest management program.

|Considering Specialty Crops?||
Over the years in extension I have often had opportunity to consult with folks interested in growing specialty crops. Many have experience with other agricultural crops and have been farming for years, some are already involved in some aspect of specialty crop farming, while a fair share are new growers with limited experience. Many have preconceptions and are idealistic in their goals; others being more practically grounded.

|Consumer Campaign Targets Ethnic Produce at Arlington Markets||
The immigration boom of the 1990's has changed the landscape of Washington DC and its surrounding suburbs. According to 2000 census figures, more than one in four Arlington residents is originally from another country. In Arlington County, roughly half of the immigrants are from Latin America, but newcomers have arrived from far and wide with other large groups coming from India, Vietnam, Ethiopia, Mexico, Philippines, and Pakistan. The growing diversity in Arlington has brought with it many new influences, including food from other cultures.

|Diamondback Moth in Virginia||
The Diamondback moth (DBM), Plutella xylostella (L.), is considered to be the most destructive insect pest of crucifer crops worldwide. DBM larvae feed on leaves of crucifer crops such as cabbage, broccoli, cauliflower, collards, kale, kohlrabi, Chinese cabbage, and Brussels sprouts. All plant growth stages from seedling to head are susceptible to attack. DBM larvae can reach high densities and cause substantial defoliation as well as contamination and malformation of heads in cabbage, broccoli, and cauliflower. The absence and reduction of effective natural enemies, especially parasitoids, as well as insecticide resistance, contribute to the status of DBM as a pest.

|Fall Armyworm in Vegetable Crops||
Scientific Name: Lepidoptera: Noctuidae Spodoptera frugiperda (J.E. Smith)
Color: Larvae vary in color from light tan or green to dark brown (nearly black) [base color ranging from yellow-green to a dark brown to gray] with three yellowish-white lines down the sides and back from head to tail and four dark circular spots on the upper portion of each abdominal segment. Front of the head is marked with a prominent inverted white Y, but this characteristic is not always a reliable identifier. The forewing of adult male moths is generally shaded gray and brown, with triangular white spots at the tip and near the center of the wing. The forewings of females are less distinctly marked, ranging from a uniform grayish brown to a fine mottling of gray and brown. The hind wing is iridescent silver-white with a narrow dark border in both sexes.
Description: Larvae are hairless and smooth skinned (See Fig. 1).

|Forced-Air Produce Cooler||
Field heat removal from freshly harvested produce is critical for subsequent handling and storage. Heat removal should be done immediately after harvest to maximize storage potential of the produce. The longer heat removal is delayed, the shorter the shelf life. Force air cooling has been design to remove field heat to bring the produce temperature down to the storage temperature.

|Peanut Variety and Quality Evaluation Results, 2015 I. Agronomic and Grade Data||
Due to suitability to the environmental conditions and existence of a strong peanut industry tailored to process primarily the large-seeded Virginia-type peanut, growers in Virginia, North Carolina, and South Carolina generally grow Virginia-type cultivars. In the view of a common interest in the Virginia-type peanut, the three states are working together through a multi-state project, the Peanut Variety Quality Evaluation (PVQE), to evaluate advanced breeding lines and commercial cultivars throughout their production regions. The objectives of this project are: 1) to determine yield, grade, quality, and disease response of commercial cultivars and advanced breeding lines at various locations in Virginia and the Carolinas, 2) develop a database for Virginia-type peanut to allow research-based selection of the best genotypes by growers, industry, and the breeding programs, and 3) to identify the most suited peanut genotypes for various regions that can be developed into varieties. This report contains agronomic and grade data of the PVQE tests in 2015.

|Specialty Crop Profile: Asparagus||
Asparagus, (Asparagus officinalis), is a hardy perennial vegetable belonging to the Lily Family. It is grown for its succulent early spring vegetative shoots that originate from an underground crown (Figure 1). Nutritionally, asparagus is almost 92 percent water, and it provides fairly high amounts of carbohydrates, vitamin A, riboflavin, niacin, thiamine, and phosphorus. A native of coastal Europe, asparagus has naturalized over much of the eastern United States. With the assistance of man and birds that have spread the seeds, asparagus can be found in gardens, old homesteads, fencerows, roadsides, and railroad right of ways across the state. It is well adapted to most of Virginia, preferring well-drained loam soils and easily tolerating winter cold and summer heat. Asparagus is long lived, and a well-managed planting can last 10 to 15 years. For those considering it as a potential crop, good planning and soil preparation are essential for long-term success.

|Specialty Crop Profile: Globe Artichoke||
Globe artichoke (Cynara scolymus L.) is an herbaceous perennial that is grown for its tender, edible, immature flower buds. The globe artichoke should not be confused with Jerusalem artichoke, another member of the composite family native to North America, which is grown for its fleshy tubers. Globe artichoke plants can become large: four to five feet tall and wide, with long, heavily serrated silvery green leaves (Figure 1a). Unopened flower buds resemble large pinecones (Figure 1b). Buds can grow up to three to four inches in diameter, are rounded at the base, and tapering to the tip or blocky in shape. Many spiny, pointed, green bracts (small, leaf-like structures) surround the hidden flower parts. The buds are harvested at an immature stage before they open and expose the flower. The base of each bract and the large fleshy base or receptacle (artichoke “heart”) on which the flower and bracts are borne are fleshy and edible. If the buds are allowed to mature and open, the resulting flowers are quite attractive, large, and fragrant (Figure 1c) , but the base and bracts harden and become inedible.

|Specialty Crop Profile: Ornamental Gourds||
Ornamental gourds are an important addition to the fall sales mix, along with pumpkins, Indian corn, and fall mums (Figure 1). They fit both direct market and commercial bulk sales outlets. Like pumpkins, gourds are usually packed by bulk box or bin for shipping. In direct markets, they usually are sold by the piece, sometimes by weight. Compared to pumpkins, gourd market windows are longer with the advantage of being sold through the Thanksgiving holiday season. Gourds also can be sold throughout the year as a decorative craft items, such as birdhouses and carved or decorated gourds (Figure 2). Gourd crafting represents a significant value-added opportunity for the creative marketer and is not bound by traditional marketing seasons for produce.

|Specialty Crop Profile: Rhubarb||
Rhubarb (Rheum rhabarbarum) is an herbaceous edible perennial and a member of the buckwheat family. It has also been classified as Rheum rhaponticum, Rheum x hybridum, and Rheum x cultorum, and there are many related, non-edible Rheum species. It is native to Siberia, and has been used as a medicinal plant in Asia for over 5,000 years. Rhubarb was once a very well-known and popular vegetable in this country. But it is not as widely grown as it was in the past. Introduced by European settlers in the 1700s, it is commonly known as “pie plant” and is grown for its edible, but very tart leaf petioles (leaf stalks), which can reach 12 to 18 inches long and one to two inches thick with a crispy texture similar to a large celery stalk (Figures 1a, b). The leaves are toxic because of their oxalic acid (soluble oxalates) content, which can cause human and animal poisoning and must be trimmed from the petiole prior to use.

Nut crops such as walnuts (Juglans nigra) and pecans (Carya illinoensis) have potential for small-scale production and direct marketing in many parts of Virginia. Growing and handling are specialized, and while marketing is niche oriented, demand can be good for fresh, high quality nuts, used both for eating out of hand and for cooking purposes.

Adults and nymphs suck sap, feeding primarily on buds and seedpods. This feeding results in weakened plants and malformed buds and fruit. On okra and bean pods, the damage appears as pimples or wart-like growths. On tomatoes and peppers, white marks, often resembling halos, appear on the fruit. On pecans and beans, the damage shows up as brown spots on the nutmeat or seed. On some tree fruit, stink bugs can cause a deforming condition called cat facing on the fruit.

|String Trellising of Tomatoes to Improve Quality and Profits||
Tests to compare caging, ground culture, and trellising systems of tomatoes were conducted at the Virginia Tech Horticulture Research Farm in the early 1970's with earlier determinate or short growing tomato varieties. Varieties with fewer vines and "self-topping" types were grown in short cages on mulches as early season companions to later-maturing trellis varieties. Many growers adopted short cage culture, using black plastic mulch under the determinate vines.

|Taking Another Look At Globe Artichokes At Virginia Tech||
Many readers may be familiar with globe artichoke, an herbaceous perennial and relative of thistle harvested for its immature flower buds. The market for this crop is dominated by California, which has several coastal areas amenable to perennial production of this unique crop. In recent years, annual production of artichoke in the desert areas of California and Arizona has grown, where off-season production under cooler winter temperatures is employed.

|Time to Plant Garlic||
Garlic is an important crop for many market growers in Virginia. For direct marketers, garlic can be an important sales item to complement other early summer crop offerings. Though it requires advance site preparation and planning, garlic is generally an easy crop to grow, and one which lends itself well to organic production.

|Tips for Handling Gourds this Fall Season||
Each year I observe more direct market and wholesale growers adding gourds to their fall sales mix, along with pumpkins, ornamental corn and fall mums. Proper harvest timing, handling and curing are important to ensure maximum longevity of gourds once the consumer brings them home.

|Wireworm Pest Management in Potatoes||
Wireworms are the subterranean larval stage of click beetles (Coleoptera: Elateridae). They are pests of many agricultural crops including corn, sorghum, small grains, tobacco, and various vegetables, but are particularly damaging to potatoes, since the marketable portion of that crop is in the soil. Wireworms are found throughout the world, and species vary greatly across regions. In Virginia, three important pest species of agricultural crops are the corn wireworm, Melanotus communis, the tobacco wireworm, Conoderus vespertinus, and a related species, C. lividus (Fig. 1). A field survey of more than 60 fields in eastern Virginia from 2002 to 2004 revealed that 80% of wireworms collected were the corn wireworm, M. communis. This is the primary soil pest attacking potatoes in Virginia.
