Technical Abstract: The concept of utilizing organic amendments to manage plant-parasitic nematodes is not new, but the widespread implementation of this management practice has still not been realized. The use of organic amendments for plant-parasitic nematode management is a complex process requiring an understanding of the transformation and generation of active compounds. As a result, research endeavors to understand and maximize the use of this management practice require a multi-disciplinary approach which draws upon the expertise of nematologists, microbiologists, natural product chemists and soil scientists. Factors that require analysis and clarification include lethal concentration levels of organic amendments necessary to kill nematodes; chemical composition of incorporation material; fate and exposure potential to nematodes of compounds released into the soil; understanding of how the environment (i.e., temperature, microbial community, soil type) influences the activity of organic amendments. Examples of research conducted in a collaborative manner on rye (Secale cereale) and brassiceous cover crops, as well as a biosolid amendment, will demonstrate the power of multi-disciplinary research. Only through collaborative research can consistent and reliable nematode suppression with organic amendments be achieved.
