Michigan Apple Committee announces 2025 research projects

The Michigan Apple Committee (MAC) has approved funding for 10 research projects that address challenges growers face in producing apples.

For 2025, the board allocated $249,995 for the projects that range from studying lenticel breakdown in apples to assessing insecticide resistance of oblique banded leafroller populations in Michigan apples. 

Every year, a subcommittee selects projects that align with MAC’s research priorities. The goal is to select projects that improve profitability and production and explore new markets. MAC aims to back innovative research that boosts the reputation of Michigan apples, according to a news release.

The projects include these topics:

• Fungicide resistance screening and testing alternatives in the apple scab and bitter rot pathogens
• Managing Honeycrisp fruit growth rate to mitigate bitter pit
• Efficacy trials for early-, mid- and late-season thinning
• Woolly apple aphid biology and management
• Assessing insecticide resistance of oblique banded leafroller populations in Michigan apples
• Increasing apple production profitability by optimizing pollinizer efficiency in single variety blocks
• Developing the native apple as a model for understanding spring frost resistance in commercial apples

“MAC welcomes proposals from various research institutions and centers of excellence. We are fortunate to have Michigan State University’s agricultural expertise nearby, fostering collaboration among institutions and colleagues,” Diane Smith, MAC’s executive director, said in the release. 

The research subcommittee is made up of growers selected by MAC’s board of directors. Committee members evaluate research project proposals and recommend funding to the board.

Based in Lansing, Michigan, MAC approved the projects during its March board meeting.
