Michigan Christmas Tree Industry Research Priorities 2020
Reducing/eliminating cone production • Look at using PGR’s or herbicides to reduce the cost of picking cones. • Evaluate other plantation management that may influence early coning.
Weed management • Evaluate new herbicides for use in Christmas tree production. Particularly broadleaf herbicides to use after bud break. • The effects of long term glyphosate use on tree growth • Herbicide programs to use with ground covers • Herbicide resistance issues – Stinger, Velpar and Round-up
Improved Genetic • Help establish seed orchards • Crosses with fir’s – example: Concolor X Fraser • CoFirG trials of Turkish fir • Develop trials looking at traits for “target” seedling vs just height (example caliper, root shoot ratio) to improve establishment.
Pest Management (insects and diseases) • Evaluate new fungicides for use in Christmas tree production • Emerging pest issues – Hemlock and balsam woolly adelgid, midges, etc. • Sustainable pest management • Ways to get off the pesticide treadmill • Organic options
Nutrient management • Looking at nitrogen management • Using N inhibitors • Rates and timing to maintain color at harvest
