Possible Mummy berry infection in the next few days in Midcoast
From today, I have a report of approximately 30% of stems with F2 (susceptible) flower buds in Waldoboro and about 20% in Searsport fields. Other fields in Warren, West Rockport and Hope were lower with approximately 15% of F2 flower buds. Mummy berry plots had cups in Waldoboro and Searsport and West Rockport had pinheads so the mummy berry fungus is progressing.
If you have an early field with flower buds at about 30 to 40% F2 and a history of mummy berry, there may be an infection period in your field over the next couple of days with the rain forecast to fall tonight through Thursday night.
Please reference the 2022 Fungicide Chart for product options AND if you send your berries to a processor, please check with your processor on allowed fungicides in the market for your berries.
