Yes, you can use EarthCare Rose Black Spot & insect spray on plants other than roses.
While this specific product is highlighted as being "ideal to use on all types of roses", the manufacturer also explicitly states that it is "suitable for use on all flowering and ornamental plants including shrubs, annuals and perennials."
This means the formulation is designed to be effective against common issues (like black spot and insects) while being safe for a wider variety of garden plants.
Why Use Rose Spray on Other Plants?
Often, rose sprays are formulated to tackle specific pests and diseases common in gardens, such as aphids, mites, black spot, and powdery mildew. Since these issues are not exclusive to roses, a spray designed to combat them effectively on roses may also provide protection or treatment for other vulnerable plants.
Based on the reference, this particular rose spray has been deemed appropriate for a broad spectrum of non-rose plants.
