A question was posed on P2 tech concerning biotech. Since we have a P2 Turfgrass stewardship program (in partnership with MSU) I sent the question over there for a response. I hope you find the attached useful. Wendy Wendy Fitzner, Chief Program Management Unit Pollution Prevention Section Environmental Assistance Division Michigan DEQ P.O.

Dr. Joseph Vargas Jr., Professor of Plant Pathology at MSU has been working to develop biological organisms for the control of turfgrass diseases for many years. His laboratory released bacterial organisms in recent years that have been demonstrated to reduce the severity of several turfgrass pathogens. While these bacteria are shown to be effective under laboratory conditions, the initial field work was inconsistant and unreliable. To be effective under field conditions, the bacteria need to be present in high concentrations during the time that the fungal organisms are infecting and damaging turfgrass plants. The Bioject is a peice of equipment that "brews" and delivers the bacteria to the golf course turf via the irrigation system. It is a rather elaborate system that has a large stainless steel incubator (30-150 gallons). Each day, the bacteria are placed in the incubator along with a food source and water. Conditions are provided for the organisms to multiply in the incubator. Then, the bacterial solution is injected into the irrigation system and applied over the golf course with irrigation water. The system starts again the next day so the organisms are appied each day to sustain the bacterial populations appropriate for disease suppression. After 2-3 years of use in Michigan, the results are still variable, but some sites are documenting significant reductions in fungicide use. The Huron-Clinton Metropark golf courses have installed biojects at most of thier sites. There are over 200 systems in place around the country, with most being here in Michigan. We have one in place at the Hancock Center if you are interested in seeing one in action, or would like to veiw any of the research plots. The Bioject supplier here in Michigan is Benham Turf Partners in Farmington Hills - 248-474-7474. Dr. Joseph Vargas's lab can be contacted at 517-353-9082.
