Spotted wing drosophila, Drosophila suzukii Matsumura, a native of eastern and southeastern Asia, is pest small stone fruits. First detected in California 2008, the insect now found across Pacific Coast states. Its penchant for attacking healthy, ripening fruit (as opposed to overripe rotting favored by other so-called “vinegar flies”) makes it potential economic threat host soft- thin-skinned crops including cherry, raspberry, blackberry, blueberry, strawberry, peach, plums, pluots,...

Economic costs of spotted wing drosophila (SWD) include yield and associated revenue losses, labor material for monitoring management losses due to the closure export markets should fruit from SWD-infested regions be banned by trading partners. This analysis focuses on two types loss in California raspberry strawberry industries: absence management, insecticide a per treatment basis. It computes cost specific program raspberries California's Central Coast region.Insecticide application are...

Abstract BACKGROUND The spotted wing drosophila ( SWD ), Drosophila suzukii (Matsumura), is an invasive vinegar fly with a preference for infesting commercially viable berries and stone fruits. infestations can reduce yields significantly, necessitating additional management activities. This analysis estimates economic losses in the California raspberry industry that have resulted from invasion. RESULTS producers experienced considerable revenue costs first years following 's invasion of...

The phase-out of methyl bromide as a soil fumigant for strawberry ( Fragaria × ananassa , Duch.) and increasingly strict regulations all fumigants suggest that non-fumigant methods disinfestation are needed. In warm climates, solarization controls soilborne pests, but fog lower summer temperatures in coastal California render it unsuitable pest control relative to chemical fumigation. first objective this study was test the efficacy steam controlling pests production. second determine if...

Abstract The broiler industry presents two puzzles regarding production contracts: why do processors control growers' inputs, and they use a statistically insufficient estimator to calculate compensation? This paper provides an agency theoretic framework that explains these in terms of processors' response grower heterogeneity risk aversion. Processors inputs reduce the information rents paid agents. By forcing agents bear additional income through imprecise estimator, can increase profits,...

Abstract Food‐safety incidents disrupt impacted markets, cause destruction of edible product, shake consumer confidence, and impose economic losses upon participants across the implicated supply chain. Despite prevalence such incidents, we know surprisingly little about their chain impacts, especially in modern produce markets where contracts may impede diffusion price impacts through The November 2018 E. coli incident for romaine lettuce Central California roiled North American throughout...

Abstract Over the last two decades, number of honey bee colonies performing pollination services for California almond industry has grown steadily and now equals a substantial share all in United States. Most US beekeeping operations have not expanded their colony numbers at current levels fees. Thus, as acreage increased, marginal supplier moved further away from California, increasing interstate shipments. We provide conceptual representation supply demand U.S. pollination, utilize...

Quality considerations are increasingly important drivers of production and coordination choices for players in the agrofood chain. Incentive contracts between farmers processors, shippers, other buyers an popular means coordinating to improve food quality. This review examines economic literature regarding incentive provision quality, with a focus on empirical analyses. Studies specific value chains find that desire higher quality or attributes increases likelihood contract, rather than...

Governments, nonprofit organizations, and grower groups have expended considerable resources on agricultural extension education programs, even though the evidence regarding impact of these programs farmers’ technology choices productivity is mixed. Many studies finding substantial effects methodological problems. We control for problems by using a panel selection model to examine effect Biologically Integrated Orchard Systems program California almond growers’ replacement organophosphate...

Most agricultural policy analysis assumes that markets are perfectly competitive, despite increasing evidence to the contrary. We demonstrate interaction of market power and government intervention may lead outcomes counter key results for competitive markets. show reduce or eliminate entirely net welfare benefits from removing two traditional support mechanisms, price floors deficiency payments, increase considerably government's cost implementing either them. Accordingly, optimally...

California strawberry production accounts for 18% of total methyl bromide use in U.S. agriculture. Under the Montreal Protocol, was slated to be banned United States 2005. A critical exemption obtained agriculture 2005 and 2006, but phaseout continues. We examine ban's effects on industry, individual regions state. most likely scenario, industry revenue will decline by 6–17% due ban. The differ region, seasonal differences demand production, possibility increased foreign competition.

Methyl bromide has been applied to California strawberries for forty years. However, it will be banned in the United States and other developed countries 2005. Critical use exemptions provide a mechanism that allows its continued after this date industries do not have technically economically feasible alternatives, are consequently subject significant market disruption. Integrating scientific economic results from multidisciplinary research project, we evaluate whether eligible critical exemption.

Contracting and other forms of vertical coordination are important parts the supply chains for many agricultural products. Often buyer cares about multiple product attributes affected by a grower's actions. Using data that insulated from common methodological problems, we test whether or not price incentives two processing tomato quality exhibit complementarity in improving delivered quality. Price substitutes provision one complements other. This finding has consequences profit‐maximizing...

Crop diseases and how they are managed can have a large impact on agricultural productivity.This paper discusses the effects productivity of Verticillium dahliae, soil borne fungus that is introduced to via infested spinach seeds causes subsequent lettuce crops be afflicted with wilt.We use dynamic structural econometric model wilt management for in Monterey County, California examine crop-fumigation decisions grower welfare.We also discuss our research externalities arise renters, between...

The California wine industry is growing and changing amidst a global revolution in grape growing, production, marketing consumer tastes. accounted for roughly 90% of the value U.S. production 2006. per capita consumption quality consumed continue to rise. largest wineries have long most shipments expand with respect volume number labels. While small sell their directly end-users, many midsized face challenges an increasingly crowded marketplace.

The recent phase-out of the soil fumigant methyl bromide (MB) due to its impact on stratospheric ozone presents a huge challenge strawberry nursery producers. We evaluated effectiveness alternative fumigants pests and plant productivity, as well production costs in California nurseries. Our trials followed stock through low- high-elevation phases runnerplant propagation complete cycle fruit coastal fields. Plant yields from nurseries Oxnard Watsonville indicated that plots treated with...
