Estimated Impact Of X-Disease And Little Cherry Disease In Washington And Oregon From 2015 To 2020, Cody Molnar, Tianna Dupont, Ashley Thompson

The Journal of Extension

X-disease phytoplasma and little cherry virus 1 and 2 have resulted in substantial loss of stone fruit acreage in Washington and Oregon. The extent and financial impact on the industry was not previously known. A Washington and Oregon State University survey documented 238,856 trees equivalent to 974 acres of sweet cherries removed due to X-disease and little cherry disease between 2015 and 2020. Removed trees reduced revenue to the industry by an estimated $30 million in 2020 and $65 million between 2015 and 2020. Over the seven-year re-establishment period estimated lost revenue and establishment costs to growers is an estimated …

Is There An Economic Advantage To Planting Diverse Summer Annual Forage Mixtures?, Kelly Mercier, Chris Teutsch, Ray Smith, Kenny Burdine, Edwin Ritchey, Eric Vanzant

The Journal of Extension

This study examined economic implications of planting summer annual mixtures of grasses, legumes, and forbs at varying nitrogen rates. No differences in yield occurred between the three mixtures, indicating that mixtures with lowest seed cost will be most economical. Applying N resulted in yield increases of 12.26 lb DM per lb N applied. Although yield responses to N were positive, sensitivity analyses showed that applying N resulted in positive net returns only when hay prices were high and N prices were low. When utilization rates are accounted for, enterprise budgets determined grazing to be 18% cheaper to implement than haying.

An Economic Impact And Investment Analysis Of Armillaria Root Rot In The United States Peach Industry, Gracie Herrin

All Theses

Peach production in the United States has decreased over the last decade due to increased disease prevalence. Armillaria root rot (ARR) is a lethal root fungus that affects many stone fruits, including peaches, often leading to rapid decline/death of trees and abandonment of orchards. This thesis is divided into four chapters which focus on answering four key questions that, to the best of my knowledge, have not been addressed in previous industry research.

The second chapter determines the magnitude of ARR disease prevalence in the United States and producers’ maximum willingness to pay (WTP) for a theoretical ARR-resistant rootstock. Results …

Engaging Farmers, Culinary Schools, And Communities In Value-Added Production To Strengthen Local Food Systems, Lauren B. Errickson, Ethan D. Schoolman, Virginia Quick, Sarah Davis, Anthony Capece

The Journal of Extension

Value-added products can generate farm income and improve community food access, yet lack of available kitchen infrastructure and labor can limit farm production capacity. This project explored how community-based culinary schools might fill the gap. A unique “product share” model was identified and piloted, meeting the collective needs of farmers, a culinary school, and urban consumers. By researching farmer crop availability and business model preferences, and aligning value-added production with community food preferences, we demonstrate a successful pilot indicative that similar initiatives can be replicated in other metropolitan areas, with potential to engage cross-disciplinary extension professionals.

The Adoption Of Food Safety Practices And The Implications Of Regulation For Small Scale Farms, Elizabeth Canales, Juan Silva, Joy Anderson

The Journal of Extension

In this article we examine the adoption of food safety practices among produce growers in the south and discuss implications of food safety regulations in the U.S. Produce growers have adopted standard food safety practices to varying degrees, but there is still an adoption gap, particularly among small scale operations. Market-driven and regulatory food safety enforcement continues to tighten, and this can further hinder market access for small scale producers.

Economic Implications Of The Mexican Fruit Fly Infestation In Texas, Samuel D. Zapata

The Journal of Extension

The Texas citrus industry is threatened by the presence of Mexican fruit fly. The objective of this study was to estimate the economic losses caused by this invasive pest. Economic impact is estimated in terms of loss in revenue and increase in operating costs. Under current quarantined areas and pest management strategies, the Texas citrus industry could experience an annual economic loss of $5.79 million. The analysis was extended to evaluate the economic impact associated with different quarantined area scenarios. This article can be used to increase awareness and adapted to estimate the economic impact of emerging invasive pest outbreaks.

Characterizing The Decision Process In Setting Corn And Soybean Seeding Rates, David A. Hennessy, Alexander J. Lindsey, Yuyuan Che, Laura E. Lindsey, Maninder Pal Singh, Hongli Feng, Elizabeth M. Hawkins, Sakthi Subburayalu, Roy Black, Eric A. Richer, Daniel S. Ochs

The Journal of Extension

Selecting optimal corn and soybean seeding rates are difficult decisions to make. A survey of Ohio and Michigan farm operators finds that, although generally keen to learn from others, they tend to emphasize their own experience over outside information sources. Soybean growers declare university and extension recommendations as more important than do corn growers. In response to direct queries and in free comments, growers place more emphasis on understanding the agronomic and technological problems at hand than on adjusting to the market environment. Given the decision environment, we argue that these responses are reasonable.
