Latino Immigration And Community Development In Rural Nebraska, Daniela Mettos

Cornhusker Economics

"Community" originates from the Latin "communis," meaning common. A community can be defined as a group of people who know one another and share common cultural traditions, interests, concerns, and objectives mainly because they have always interacted on a regular basis. To most rural people, community means the same familiar faces and places, a daily routine, social systems and norms they understand, things they have always done. This scenario has been changing with the influx of immigrants in rural areas. Nowadays, rural community residents find themselves sharing their place with new people from distant regions and different cultures.

Analysis Of Asynchronous Supplemental Course Modules In Statistical Process Control, Matthew E. Harvey, John R. Haughery, Sai K. Ramaswamy

Sai Ramaswamy

Many engineering and technology departments at the collegiate level have developed extensive online and hybrid (face-to-face and online) course offerings (Bourne, Harris, & Mayadas, 2005). These courses may meet several goals such as increasing access, reducing university costs, providing schedule flexibility, and increasing curriculum offerings. An additional opportunity for computer-based learning is to increase student success by offering asynchronous learning modules to extend content beyond traditional lectures.

Repeated Applications Of Callisto And Devrinol On Newly Planted Cranberry Vines, Hilary A. Sandler, Katherine Ghantous, Krystal Demoranville

North American Cranberry Researcher and Extension Workers Conference

Abstract:

To evaluate the weed control provided by various combinations of preemergence applications of Devrinol (napropamide) and postemergence applications of Callisto (mesotrione) in newly planted and 1-yr-old cranberry vines, six 2-yr experiments were conducted during 2009-2012. Three sites were treated in the year of planting plus the subsequent year (called “new plantings”) and three sites were treated in their second year of growth plus the subsequent year (called “second-year plantings”). Ten treatments, delivered in 3,735 L ha^-1 water, were administered each year: Devrinol at 3.36 kg ai ha^-1 applied once, twice, thrice or once followed by (fb) one …

Screening Of Post Herbicides For Controlling Carolina Redroot (Lachnanthes Caroliana) In New Jersey Cranberry Beds, Thierry Besancon, Baylee Carr, Peter Oudemans

North American Cranberry Researcher and Extension Workers Conference

Abstract.

New Jersey produced 27 million kg of cranberries in 2015 at a farm value of $22 million (USDA 2017). Cranberry beds in New Jersey are concentrated in the Pine Barrens coastal plain where soil conditions (sandy texture, pH 4.0 to 5.0, good drainage) are optimal for cranberry production. The perennial nature of cranberry production predisposes the crop to a diversity of weed species ranging from herbaceous weeds to woody perennial species. Among perennial weed species, Carolina redroot has been an increasing source of concern for New Jersey cranberry growers regarding the lack of sufficient control from their current management …

Biocontrol Of Moss With Sodium Bicarbonate, Jocelyn Moreau

North American Cranberry Researcher and Extension Workers Conference

Abstract:

Cranberry growers struggle with controlling the presence of moss of different species in their fields. Few chemical treatments have been tested in the past with mixed results. In organic production, no solution is available for such control. A few web references mention the use of baking soda on driveways and other structures in order to eradicate mosse. The aim of this project was to assess the effectiveness of sodium bicarbonate to control moss in productive cranberry bogs without damaging the plants.

Many sources of information on the Web refer to a dose of 30 g / liter (4oz / …

Moss As An Emerging Weed Problem In Cranberry, Katherine Ghantous, Hilary A. Sandler

North American Cranberry Researcher and Extension Workers Conference

Abstract:

Moss is an emerging weed issue in Massachusetts and other cranberry growing regions. Although present in cranberry for decades as a minor weed, growers have recently begun to perceive it as becoming more widespread and difficult to control despite practices, such as improved drainage and water management, that should discourage moss growth. Of growers surveyed at the 2016 UMass Cranberry Management Update Meeting, 67% reported having moss on their farms (n=100), 41 % said they felt it was more common than it was 5 years ago (n=85), and 41% said they considered moss to be a problematic weed (n=96). …

Predictive Models Of Moth Development, Elissa Chasen, Shawn Steffan

North American Cranberry Researcher and Extension Workers Conference

Abstract:

Degree-day models link ambient temperature to insect life-stages, making such models valuable tools in integrated pest management. These models increase management efficacy by predicting pest phenology. In Wisconsin, the top insect pest of cranberry production is the cranberry fruitworm, Acrobasis vaccinii Riley (Lepidoptera: Pyralidae). Control of this species is often complicated by the fact that the larvae feed entirely within the fruit. Timing of control tactics is therefore critical and generally targets the adult and egg stages. The first part of this research was conducted in the laboratory to determine the upper and lower temperature-mediated growth thresholds of this …

Progress In The Mechanization Of Mating Disruption Deployment, Natalie Eisner, Elissa Chasen, Brian Luck, Shawn Steffan

North American Cranberry Researcher and Extension Workers Conference

Abstract:

The American Cranberry, Vaccinium macrocarpon Aiton (Ericaceae) is the most significant fruit crop in Wisconsin, accounting for almost 85% of the states total value of fruit production. A challenge faced by cranberry growers is managing for insect pests that cause economic damage. Presently, growers use insecticides to manage insect pest populations. However, insecticides also cause mortality in beneficial insects - including pollinators and natural enemies. An alternative for reducing insect populations in cranberry marshes is Mating Disruption (MD), which uses pheromones to prevent and delay mating. MD systems function by sending out false plumes of the insect’s sex pheromones …

Managing Surface Water Inputs To Reduce Phosphorus Losses From Cranberry Farms, Casey Kennedy, Peter Kleinman, Carolyn J. Demoranville, Kyle Elkin, Ray Bryant, Anthony Buda

North American Cranberry Researcher and Extension Workers Conference

Abstract:

In Massachusetts, cranberry (Vaccinium macrocarpon Ait.) production accounts for one-fourth of US cranberry supply, but water quality concerns, water use, and wetland protection laws threaten the sustainability and future viability of the state’s cranberry industry. Pond water used for harvest and winter flooding accounts for up to two-thirds of phosphorus (P) losses in drainage waters. Consequently, use of P sorbing salts to treat pond water holds promise in the mitigation of P losses from cranberry farms. Laboratory evaluation of aluminum (Al)-, iron (Fe)-, and calcium (Ca)-based salts was conducted to determine the application rate required for reducing P …

Impacts Of A Community Supported Agriculture (Csa) Voucher Program On Food Lifestyle Behaviors: Evidence From An Employer-Sponsored Pilot Program, Jairus J. Rossi, Timothy A. Woods, James E. Allen Iv

Agricultural Economics Faculty Publications

Community supported agriculture (CSA) programs have recently received attention for their potential to influence food lifestyle behaviors and health outcomes. We build on and expand inquiries into the relationship between CSA participation and behavior change by presenting the results from a controlled pilot study of first-time CSA shareholders. We offered 95 first-time shareholders a $200 voucher to participate in a CSA. Prior to and immediately following CSA participation, these shareholders completed a survey on food lifestyle behaviors. Using econometric analyses, we measured shareholder behavior changes against an 82 person control group. All participants were drawn from a pool of individuals …

Regional And Temporal Parasite Loads In Bumble Bees Associated With Cranberry Landscapes, Noel Hahn, Andrea Couto, Anne Averill

North American Cranberry Researcher and Extension Workers Conference

Abstract.

There are concerns that the fitness of bumble bees that provide pollination services to cranberry could suffer within intensively managed agricultural lands. In the cranberry region of Massachusetts, the crop occurs within urbanized coastal and sand plains that generally lack floral resources. Additional stressors that compromise the health of bumble bee colonies could be the reduction of habitat and infections by parasites. In contrast to the lack of floral resources in the region, the mass bloom of managed cranberry provides abundant floral resources around July. We examined the prevalence and intensity of pathogen infection in bumble bees collected across …

Impact Of Fertilization On The Firmness Of Cranberry (Vaccinium Macrocarpon Ait.), S.M. Reza Jamaly, Sebastien Marchand, Serge-Etienne Parent, Silvio Jose Gumiere, Jean-Pierre Deland, Leon-Etienne Parent

North American Cranberry Researcher and Extension Workers Conference

Abstract.

Québec is one of the leading cranberry (Vaccinium macrocarpon Ait.) or called ‘Atoka’ in the Iroquoian language, producers in the world. Fertilization is a key management tool to reach high fruit yield and good quality. For example, in blueberries, rates and application methods of fertilizers can affect fruit firmness. N showed the greatest effect on the development, flowering, and productivity of the cranberry plant. On the other side, hand harvesting is preferred for marketing of fresh fruit since the physical abuse of mechanical harvesting reduces fruit firmness and substantially reduces market life. The objective of this research was …

Population Densities Of Lepidopteran Pests In Selected Cranberry Cultivars In Wisconsin, Erin Mcmahan, Shawn Steffan, Christelle Guedot

North American Cranberry Researcher and Extension Workers Conference

Abstract:

Host plant resistance, an important strategy of integrated pest management, was examined in the American cranberry, Vaccinium macrocarpon Aiton (Ericaceae). Despite the pressure on cranberry growers to reduce pesticide usage, host plant resistance is not used to help manage insect populations. This study measured field population densities of the three most economically important pest insects in Wisconsin, namely, cranberry fruitworm (Acrobasis vaccinii Riley), sparganothis fruitworm (Sparganothis sulfureana Clemens), and blackheaded fireworm (Rhopobota naevana Hu¨bner), in five different cranberry cultivars, i.e., ‘Stevens’, ‘Ben Lear’, ‘GH1’, ‘Mullica Queen’, and ‘HyRed’.

Population densities of male moths of all three …

Soil Moisture Management And Variability In Cranberry Beds, Peter Jeranyama, Casey Kennedy, Carolyn Demoranville, Rebecca Brennan

North American Cranberry Researcher and Extension Workers Conference

Abstract.

Summer irrigation is a major management input in cranberry production, and traditionally, cranberry beds have received 25 mm of water per week from either rain, capillary action from groundwater, irrigation , or some combination of these from late spring through the summer. However, environmental conditions and drainage characteristics can vary from bog to bog, meaning that the 25-mm rule does not always result in ideal soil moisture conditions. Measurement of cranberry soil water status has been based on two technologies; (i) measuring the amount of water in the soil using volumetric water sensors or measuring the depth of the …

New Brunswick Cranberry Industry Update, Gavin Graham

North American Cranberry Researcher and Extension Workers Conference

Abstract:

New Brunswick growers produced cranberries on over 900 acres in 2016 and had a record harvest of 13,780 barrels last season. Growers are having difficulty navigating the low price concerns, and have begun to limit expenses and treatments as best they can. They are monitoring for pesticide application more than ever and have moved towards more effective use of irrigation in recent years. Weeds are beginning to be more problematic in fields, but this could also be from a mild winter. Other pest pressures have been low in 2017. One grower had extensive early leaf drop in the spring, …

Cranberry Toad Bugs: What Are They?, Cesar Rodriguez-Saona, Vera Kyryczenko-Roth, Robert Holdcraft

North American Cranberry Researcher and Extension Workers Conference

Abstract:

In recent years, there has been an increased concern among New Jersey cranberry growers for the potential increase in secondary pests, such as the cranberry toad bug Phylloscelis atra (Hemiptera: Dictyopharidae), because of changes in pest management strategies (e.g., adoption of new reduced-risk products and decreased applications of broad-spectrum insecticides). In 2013, we observed damage in cranberry bogs caused by the cranberry toad bug in New Jersey. Here we report results from studies being conducted to: 1) determine the life cycle of cranberry toad bugs in New Jersey cranberries; 2) determine the impact of toad bug feeding damage on …

The Usda Cranberry Entomology Lab: Highlights From 2011-2016, Shawn Steffan

North American Cranberry Researcher and Extension Workers Conference

Abstract:

Biological, chemical, and cultural control methods have been investigated as part of the cranberry crop protection program pursued in the USDA Cranberry Entomology Laboratory. Surveys of native entomopathogenic nematodes in Wisconsin have produced a new bio-insecticide agent (Oscheius onirici subsp. wisconsinensis), which shows high virulence against flea beetles, cranberry fruitworm, and sparganothis fruitworm. Other biological control studies have examined spider densities in flooded vs. sprayed cranberry beds, showing that flooding conserves hyper-abundant beneficial arthropod populations, such as spiders and springtails. Flooding also appears to directly reduce populations of black-headed fireworm and sparganothis fruitworm, while having no negative …
