Industry Priorities

  • Support research to address emerging chestnut pest issues through continued partnership with
    Michigan State University, MSU Extension, Michigan Department of Agriculture, and other relevant
    industry partners. Current areas of concern include Asian Chestnut Gall Wasp (ACGW), chestnut
    weevil, and pre/post-harvest nut rots. These problems have come to Michigan and must be well
    managed to allow sustained and increased profitability of the chestnut industry.
  • Develop a chestnut orchard curriculum to support new and experienced growers. Very few new
    chestnut growers come to the industry with past orchard or horticultural experience, and this can
    impair productivity and efficiency in their orchards.
  • Improve chestnut crop estimating and market projection data to optimize industry scaling for
    processing and marketing. No benchmark data exists for yield estimation or projection and at the
    current time, chestnuts have tended to bear larger yields every other year. Pollination is subject to
    weather conditions and other unknowns that substantially impair our ability to plan for harvest,
    processing, and marketing. Determining the variables of pollination and managing them will allow
    for better planning.
  • Determine optimal nutrient and moisture needs for chestnut production in Michigan. We simply do
    not know what specific requirements are for chestnut other than anecdotal information. For
    instance, the industry has been operating on the recommendation of a former forestry consultant
    who tested a fertilizer formulation in his own orchard. There has been no corroboration of these
    recommendations with professionally conducted research.
  • Improve chestnut harvester technology, particularly for small to mid-scale growers with emphasis
    on affordability and efficiency. In general, Chestnut growers are not closely co-located, so an on
    farm harvester matched to the specific needs of small to mid-scale growers is essential. Growers
    with large, expanding acreages will have the ability to purchase available machinery from Europe
    while smaller scale growers need cheaper and still efficient options.
  • Improve knowledge of market-based information, including consumer preferences, potential for
    diversification and value-added products, branding, and promotion; likely in collaboration with the
    growers cooperative, Chestnut Growers, Inc. Due to work done previously on chestnut promotion,
    Americans have become minimally aware of chestnuts. Research has shown that as Americans
    become more aware of American-grown chestnuts, they replace European-grown and Asian-grown
    imports, pound for pound. Given the volume of chestnut imports, chestnut promotion is crucial,
    and profitable given that our industry will grow substantially in the next decade and longer.
