Question:
What is wrong with my rose bushes?
Answer:
This is damage from the rose slug, also known as sawfly. The rose slugs eat the tissue between the veins of the leaf. This is a light to moderate infestation and the plant can withstand that amount of damage. The viewer asking the question used Bayer Systemic Rose & Flower Care which contains imidacloprid. It is likely that the treatments killed the rose slugs but the damage is still there. The plant will eventually grow out of the damage.
