Research Project: A Predictive Model to Increase Adoption of Ipm of a Mite-Virus Disease Complex in Wheat

Location: Grain, Forage & Bioenergy Research

Project Number: 3042-21000-031-10
Project Type: Reimbursable

Start Date: Jan 01, 2013
End Date: Nov 30, 2014

Objective:
The goal of this project is to develop, deploy, and assess the adoption of a disease risk assessment and forecasting model for this mite-virus complex in wheat across the Great Plains. The following objectives will be pursued: 1. (Research) Determine the impact of environmental conditions (e.g. temperature, moisture), alternate hosts, and management tactics (e.g. green bridge, resistant varieties, irrigation, nitrogen application, planting date) on vector population dynamics and subsequent disease incidence, in geographically diverse production regions across the Great Plains. 2. (Research) Identify primary interactions that occur in this mite-virus complex across the region, i.e. among the mite vectors (biotypes/haplotypes), the three viruses, and their hosts. 3. (Extension) Increase producer implementation of integrated management principles for the WCM-virus complex across a wide geographic region. 4. (Education) Develop student training opportunities and educational resources that will be used for graduate, undergraduate, and high school (targeting HS teachers) that use this mite virus complex to demonstrate the principles of biology, ecology, and IPM. 5. Evaluate the impact of the research, extension and education objectives of the project.

Approach:
The risk assessment model will be developed using historical, current, and planned research to identify risk potential of disease epidemics across the region. Demonstration trials in multiple states will contribute to and validate the models as well as serve as a focus for farmer education and student training. We will identify the impacts of environmental factors and alternate hosts on disease incidence and severity across the region. Specific integrated management plans for high risk areas will be developed and disseminated through extension and educational efforts designed to enhance producer adoption and reduce the impact of this disease complex. These activities will address regional differences in economic and social constraints of adoption, and increase producer adoption through multiple avenues of dissemination, including traditional and electronic methods (e.g. eXtension and other vehicles).
