The 1984 edition of the Blueberry Progress Reports was prepared for the Maine Blueberry Commission and the University of Maine Blueberry Advisory Committee by researchers with the Maine Agricultural Experiment Station and Maine Cooperative Extension Service at the University of Maine, Orono. Projects in this report include:
1. Control, biology, and ecology of insects affecting lowbush blueberries .
2. Chemical control of mummyberry disease (Monilinia vaccinii-corymbosi)
3. New Fungicides for control of Botrytis blossom blight
4. Nutritional survey of selected lowbush blueberry fields
5. Interaction of fertility and pruning practices on soil characteristics and lowbush blueberry growth and yield
6. Long term effects of N and NPK fertilizer on plant growth and yield
7. The effect of N fertilization on clonal spread
8. Nutritional responses of the lowbush blueberry in new plantings as related to early establishment
9. The effect of several mulches on frost heaving, soil moisture, soil temperature and rhizome development
10. Effectiveness of mulches and planted lowbush blueberry seedlings for stabilizing soils and increasing plant cover
11. Effect of surface mulches on stabilizing lowbush blueberry soil in barren areas
12. Frequency of fertility application for establishment of lowbush blueberry seedlings
13. Slow release vs liquid fertilizer for establishment of lowbush blueberry seedlings
14. Comparison of rooted cuttings and tissue culture propagated lowbush blueberry plants
15. The effect of growth regulator formulations on growth and rhizome production of the lowbush blueberry
16. Unburned, mowed fields

24. Hand-wiper applications of herbicides on birch, maple and willow
25. Glyphosate applied after leaf drop for bunchberry control
26. Napropamide for seedling weed control
27. PP333 plant growth regulator
28. Dichlobenil for bunchberry control
