The Elm Leaf Beetle has very few natural predators and as a result the best method for treatment is with pesticide. There are two main methods for Elm Leaf Beetle Control – ground drenching (soil injecting) with pesticide and or trunk injection with pesticide.
- Trunk injection – localises the rather hazardous chemicals
- Soil injection – chemical uptake through the roots though isolation is unavoidable.
At Treelife we prefer the method of trunk injection. This method significantly reduces the amount of rather hazardous chemical used. It also treats the problem tree and not everything around it. Most importantly, it significantly reduces the loss of micro-organisms that die in the soil. It is these organisms that will improve your tree’s overall health into the future.
