Brief Project Summary:

This research project will characterize the bio-control activity of a collection of fungal species isolated from soybean production fields. The ultimate goal is to use these potential bio-control agents to enhance efficiencies in managing Soybean Diseases caused by pathogens present in the soil, such as, Fusarium spp., Phytophthora sojae, Pythium spp. This can be achieved either by introducing these bio-control agents to soybean production fields, and/or by fine-tuning existing management practices so that the prevalence and activity of bio? control agents native to production fields are enhanced.

Extensive research has been conducted to identify and characterize bio-control agents...

Information And Results
Final Project Results

Fifty-eight potential bio-control agents (BCA) were tested against 7 fungal pathogens. Several specific BCAs showed activity against Fusarium graminearum, Fusarium virguliforme and Macrophomina phaseolina.

Fourteen BCAs were tested against 12 oomycete species. Some of the BCAs demonstrated trends of plant protection against particular Pythium species.

Fourteen BCAs were evaluated for their sensitivity to different fungicide active ingredients. Preliminary results indicated that some of the BCAs could be added with a fungicide seed treatment with minimal inhibition occurring.

Preliminary data indicates that, in addition to their antibiotic activity against plant pathogens, some of the BCAs also seem to induce resistance mechanisms in soybean, thus providing an additional layer of protection against seedling pathogens.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
