When it comes to garden pests, one of the most common is the leaf roller. You can identify leaf roller damage by finding rolled up leaves on your shrubs and trees. Leaf rollers can cause significant damage if left unchecked. Understand the source of the problem and effective treatments for dealing with leaf rollers in your garden and landscaping.
Leaf rollers are a group of moths and larvae that roll up or tie leaves together with silk threads. The larvae then feed on the inside of the leaves and pupate in the rolled leaves. There are several species of leaf rollers, including the cherry leaf roller, birch leaf roller, poplar leaf roller, and dogwood leaf roller.
Leafroller damage can be identified when leaves are tightly rolled or tied together. Other signs of damage include pin holes, skelΒetonized leaves, and brown patches. In severe cases, this pest may completely defoliate the foliage of affected trees and shrubs.
There are several approaches for controlling leaf rollers. To start, you should be sure to plant shrubs and trees that are resistant to this particular pest. You can also monitor the rollers closely and remove them from plants by hand. This will help to reduce leaf roller populations in the garden.
The use of chemical sprays may provide additional relief. While there are a variety of sprays available, the most effective are synthetic pyrethroid, spinosad, and Bacillus thuringiensis (BT) preparations. Applying these types of sprays will help to control leaf rollers in your garden and prevent them from doing further damage.
