Survey of Plant-Parasitic Nematode Population Densities, Virulence Phenotypes and Biological Control Agents in Mississippi Soybean Fields

Investigators

Objectives

  1. Year 1: Initiate statewide survey on nematode population and density distribution in MS soybean fields. Survey results will help growers identify PPN in soybean field. 
  2. Year 1-3: Determine the virulence phenotypes of SCN and speciation of root-knot nematode in Mississippi. Results of this project will help soybean growers to determine the right variety to use in their field and to make right rotational choices
  3. Year 1: Search for potential PPN suppressive soils in Mississippi.  Year 2 and 3: Characterization of potential biocontrol agent for PPN in Mississippi soils. Results obtained from this project will give soybean growers more options in PPN management
  4. Year 3: Generate nematode population distribution heatmap and provide up-to-date management strategies through survey results. An updated PPN management advice will be provided to soybean grower.

Expected End Results

The proposed project will address the research question on “Nematode management/Control”. Anticipated data generated from this project will arise awareness of the distribution and density of plant-parasitic nematode population in Mississippi, which is key to establish successful management strategies for soybean growers. Data generated in this project will also facilitate breeding efforts to provide more rotation options for growers. Survey will cover all major soybean production areas in Mississippi, which would potentially impact 2.3 million acres.
