We got Mummy berry last year but only identified it after hundreds of berries fell on the ground. We pruned, mulched, sprayed sulfur every 2 weeks and tried the biodynamic preparation of horsetail every week. It has shown up again this year, we are cutting off all signs of infection but we are losing everything! It is heartbreaking! Any suggestions?
Monilinia Brown Rot. Monilinia amelachieris. (Mummy Berry) Control: Remove and burn, bury or compost mummified berries and fallen leaves. No fungicides are specifically registered for this disease, but application of TOPAS 250E for leaf and berry spot should help to control Monilina rot also. Apply Topas 250E 3 times a year at white tip, petal drop and green fruit stage: 38 days to harvest. This information is from the Nursery and Landscape Pest Management and Production Guide. BCLNA, Ministry of Agriculture. Ask at your co-op or garden supply store. I have never used TOPAS and knock on wood that my blueberries stay healthy.
