Home gardeners cannot diagnose and treat raspberry plant diseases before crop loss

Home gardeners discover black streaks on raspberry plants but lack reliable diagnostic resources and treatment guidance, leading to plant death and lost harvests. Current solutions like generic gardening forums provide inconsistent advice, and by the time gardeners identify the problem (likely cane blight or anthracnose), significant damage has already occurred. Gardeners need rapid, accurate disease identification with actionable treatment steps before their plants are destroyed.
