Merit Applications

IMG_4846_cropMerit applications are used on trees such as crape myrtle, hackberry, pin oak, white birch, and flowering plum to prevent aphid infestation.  Merit applications are injected into the soil around trees and shrubs during January and February.

Merit injections are a cost effective and environmentally friendly method for controlling aphids because the application last for approximately one year.

The main alternative to merit injections is spraying trees with an insecticide that is more expensive, less effective, and can be a logistical challenge.  If not treated, the common side effect is a waxy residue/sap that drips onto cars and grounds and is transferred into the buildings by foot traffic.  Also, infestations can distort leaf growth and appearance, taking away from the beauty of your plants and trees.
