Project Summary

An evaluation of many SCN seed treatments to manage SCN and SDS symptoms to develop Missouri specific management recommendations.

Management of soybean cyst nematode has moved beyond the traditional use of resistant varieties and crop rotation. The inclusion of nematode-protectant seed treatments are an additional tool in the toolbox for management. Some of these treatments are also intended for the management of soybean sudden death syndrome. Understanding the impacts of these emerging tools on two important soybean diseases in Missouri across environments and seasons is of value to growers and MU Extension personnel.

Project Objectives

This study has three primary goals:
1. Evaluate SCN seed treatments for their ability to control and manage SCN in Missouri
2. Determine if SCN seed treatments reduce SDS foliar symptoms
3. Assess how well SCN seed treatments perform across environments

Project Deliverables

Data will be analyzed by all possible combinations of treatment and location for the three disease response variables described above.

Data generated by this study will be disseminated at Scouting Schools, through Extension and outreach programming throughout the state, and at scientific conferences.

Progress of Work

Final Project Results

Benefit to Soybean Farmers

The data generated by this project will allow for the development of Missouri specific information regarding the performance of SCN seed treatments on SCN and SDS. These impacts will be realized in the following ways: first, the information collected will be used to evaluate emerging tools in the SCN management toolbox and how nematode-protectant seed treatments perform in Missouri soils; and second, this project will allow for a better understanding how newly developed SCN management tools impact the development of SDS symptoms.

The data collected will be presented at the Scouting Schools implemented by the “MU Certified” Strip Trial Program, at MU Extension Field Days, and at other relevant regional and national conferences. In addition, the data generated by this study will be used to facilitate the development of and insight into further crop protection comparison trials through the “MU Certified” Strip Trial Program.
