Rose : Leafrollers
(revision date: 3/10/2017)

Several different caterpillars roll leaves on roses. Among these are the obliquebanded leafroller, which is green with a dark head, and the orange tortrix, which is tan to greenish with a tan head. Leafrollers are often found near the tips of shoots. They feed inside the rolled leaves, which are held in place with webbing.
Management Options

Non-Chemical Management
  • Pinch rolled leaves, killing larvae inside.
  • Encourage natural predators such as birds and predaceous beetles, which help control caterpillar populations.
Select non-chemical management options as your first choice!

Chemical Management

Apply before the leaves are rolled. Avoid Sevin (carbaryl) if there is any possibility of pesticide drifting onto nearby blooming plants. These products are toxic to bees. Bacillus thuringiensis (Bt) will control leafrollers only if they are actively feeding. Use a spreader-sticker with liquid Bt formulations.
