Simultaneous Diffusion of Herbicide Resistant Cotton and Conservation Tillage
(AgBioForum, 2009)This study used state-level data from 1997-2002 to econometrically estimate factors explaining the diffusion of two technologies by US cotton producers: herbicide-resistant (HR) cotton seed varieties and conservation ... -
Pricing of Herbicide-Tolerant Soybean Seeds : A Market-Structure Approach
(AgBioForum, 2009)This article investigates the effects of supply-side factors on the pricing of soybean seeds in the United States. We discuss recent trends that have shaped the US soybean seed market. Using an econometric model, we also ... -
Predicted Willingness of Irish Farmers to Adopt GM Technology
(AgBioForum, 2009)In this article, we use a probit model to assess the factors that will influence the decision of Irish farmers to adopt genetically modified (GM) technology should they be given a choice in the near future of selecting ... -
Potential of Herbicide-Resistant Rice Technologies for Sub-Saharan Africa
(AgBioForum, 2009)Weed-inflicted yield losses in rice equate to half the current rice imports in sub-Saharan Africa (SSA) and African rice farmers have a limited range of effective and affordable weed management technologies. Herbicide-resistance ... -
Perceived Consequences of Herbicide-Tolerant and Insect-Resistant Crops on Integrated Pest Management Strategies in the Western United States : Results of an Online Survey
(AgBioForum, 2009)We conducted an online survey to assess the potential effects of herbicide-tolerant (HT) and insect-resistant (IR) crops on integrated pest management (IPM) practices in the Western United States For HT crops, participants ... -
Overview : Herbicide Resistant Crops -- Diffusion, Benefits, Pricing, and Resistance Management
(AgBioForum, 2009)Weeds, along with insect pests and plant diseases, are sources of biotic stress in crop systems that reduce yields, raise production costs, and contribute to income risk to farmers (HarvestChoice, 2009). Transgenic, ... -
Managing the Herbicide Resource : An Evaluation of Extension on Management of Herbicide-resistant Weeds
(AgBioForum, 2009)The threat of herbicide-resistant weeds to crop production makes sustainable weed and herbicide management an important issue for agricultural extension agencies throughout the world. In this study, we examined the ... -
Glyphosate-Resistant Crops and Weeds : Now and in the Future
(AgBioForum, 2009)Glyphosate-resistant (GR) crops represent more than 80% of the 120 million ha of transgenic crops grown annually worldwide. GR crops have been rapidly adopted in soybean, maize, cotton, canola, and sugarbeet in large part ... -
Genetically Modified Crops and Household Labor Savings in US Crop Production
(AgBioForum, 2009)In spite of widespread adoption, there is mixed evidence as to whether adopting genetically modified (GM) crops increases farm welfare. One possible reason for widespread adoption is the labor savings. Using a treatment ... -
Efficiency Analysis of the US Biotechnology Industry : Clustering Enhances Productivity
(AgBioForum, 2009)This article attempts to identify the factors affecting location of biotechnology firms in the United States. To achieve this goal, the regional efficiency in the biotech industry is measured using the Data Envelopment ... -
Effects of Weed-Resistance Concerns and Resistance-Management Practices on the Value of Roundup Ready[trademark] Crops
(AgBioForum, 2009)This study estimates grower benefits of Roundup-Ready[trademark] (RR) weed management programs and how weed-resistance concerns and resistance-management practices affect those benefits. Direct survey methods were used to ... -
Corporate Pricing Strategies with Heterogeneous Adopters : The Case of Herbicide-Resistant Sugar Beet
(AgBioForum, 2009)In ex-ante impact assessment of proprietary seed technologies, the assessor operates under scarce and imperfect data. No market has been established for the new technology and adoption has yet to take place. Recently, the ... -
Characteristics of Herbicides and Weed-Management Programs Most Important to Corn, Cotton, and Soybean Growers
(AgBioForum, 2009)The introduction and rapid adoption of herbicide-tolerant crops has renewed interest in better understanding the characteristics of herbicides and weed-management programs that are important to growers besides profitability. ... -
Can Cooperative Membership and Participation Affect Adoption Decisions? Issues for Sustainable Biotechnology Dissemination
(AgBioForum, 2009)Biotechnology has become the dominate technology in the agricultural environment globally, possessing the capacity to address issues related to food insecurity and low productivity. Developing countries therefore cannot ... -
Adoption Patterns of Herbicide-Tolerant Soybeans in Argentina
(AgBioForum, 2009)The adoption of herbicide-tolerant soybeans (HTS) in Argentina was a very rapid process, as HTS covered virtually all of the area under soybean cultivation less than 10 years after their introduction in 1996. In our analysis, ... -
Adoption of Conservation-Tillage Practices and Herbicide-Resistant Seed in Cotton Production
(AgBioForum, 2009)Agricultural Resource Management Survey data for 2003 were used to estimate logit models for adoption of conservation-tillage practices and herbicide resistant/ stacked-gene cottonseed in the United States. The specification ... -
