Progress 08/15/08 to 08/14/11
Outputs
OUTPUTS: Mating disruption products for grape berry moth control were tested and the results have been delivered to the grape industries of the Great Lakes region by the project team. The degree day model that has been validated in this project has been released on the MSU Enviroweather website and is being widely used for timing sprays to control grape berry moth. The improved information on the timing of grape berry moth activity has been used to test new timings of applications of reduced-risk selective insecticides, and information on their efficacy under field-scale trial conditions was presented through extension channels to our stakeholders. We presented talks at over 20 grape grower meetings in Michigan and Wisconsin, and the results have been used to inform grape pest management in other regions. PARTICIPANTS: Luis Teixeira was a postdoc working on this project with Dr. Isaacs. We also collaborated with MSU Extension educator Mark Longstroth and with IPM educator Erin Lizotte in NW Michigan. TARGET AUDIENCES: Grape growers, extension educators, consultants, scouts, grape entomologists. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Based on the research conducted under this funding, the GBM-SPLAT product was registered for use in US vineyards by ISCA Technologies. Additionally, use of the degree day model has increased over 100% according to website access data. We have also seen that growers with larger acreages are using it to time applications for protection of their vineyards. Support from this project has allowed widespread testing of the degree day model and pheromone mating disruption across the grape Michigan's grape industries. We now have a very clear dataset showing the performance of employing the degree day model-based programs for control of this pest, and this has supported transition from broad-spectrum insecticides to more selective insecticides in this grape industry. USDA-NASS survey data have been used to document these changes, along with information from the primary juice grape processor.

Mawby Vineyards, Sutton's Bay, Michigan. Sept 2, 2010. 20 grape growers and winemakers. Late-season insect management . Grape IPM meeting. August 13, 2010. Lemon Creek, Berrien Springs, MI. 30 growers. Selecting grape insecticides. Viticulture Day 2010. July 29, SWMREC, Berrien Springs, MI. 120 grape growers/winemakers. Grape insect management. Grape Extension Meeting . SWMREC, Benton Harbor. Japanese beetle and SPLAT technology. Viticulture 2010 and 39th Annual New York Wine Industry Workshop. Rochester, New York. February 17-19, 2010. Grape Berry Moth Management with Monitoring, Models, and New Insecticides. SW Hort Days, January 4, 2010. PARTICIPANTS: Luis Teixeira was a postdoc working on this project with Dr. Isaacs. We also collaborated with MSU Extension educator Mark Longstroth and with IPM educator Erin Lizotte in NW Michigan. TARGET AUDIENCES: Grape growers, consultants, and scouts. Extension educators. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

The project was also supported by funding from NGC. TARGET AUDIENCES: Grape growers Extension educators Crop consultants PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
SPLAT-GBM now registered by the US-EPA for application to vineyards for GBM control. This project has demonstrated the efficacy of using mechanically-applied SPLAT-GBM for mating disruption of grape berry moth, by testing different application rates and timings. The mechanical applicator has been improved to become more user-friendly and reliable while maintaining low costs. The deployment of mating disruption in wooded areas bordering vineyards did not lead to a decrease in infestation in the vineyards, so this approach has not been pursued further. The efficacy of selective insecticides has been demonstrated to growers and awareness of the potential for natural biological control has increased in the grower community. MSU's online phenological model for timing GBM management activities is gaining acceptance by grape growers as a standard tool to correctly time insecticide sprays. During 2009 this website was accessed over 300 times. In addition, this work has provided the basis for expanding the use of phenological models by grape growers throughout the Midwest.
