I have a 30' bed of raspberries which produce faithfully every year, but this year I notice maybe 5% of the berries have a bleached out portion of the berry. The color is missing, and the small pieces are whitish. Otherwise they seem to be fine. the only change I made this year was to add one year old horse manure. I also spray every year in the spring. Any suggestions to eliminate this? Thanbk you Ellis 604-988-8679
