The system facilitates problem identification through a visual matching process, allowing comparison of damaged plant parts against a database of over 1000 high-resolution photos. Each image is linked to detailed descriptions of damage and developmental stages to aid in diagnostic confirmation. The platform provides management recommendations for over 200 distinct problems affecting more than 100 shrub varieties. Information within the tool is searchable and can be indexed by either shrub type or pest.
