Research Collaborations Can Improve the Use of Organic Amendments for Plant-Parasitic Nematode Management
AbstractThe 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 multidisciplinary 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; and the influence of environmental factors (i.e., temperature, microbial community, soil type) on the activity of organic amendments. Examples of research conducted in a collaborative manner with rye (Secale cereale) and a biosolid amendment demonstrate the power of multidisciplinary research. Only through collaborative research can consistent and reliable nematode suppression with organic amendments be achieved.
