Precise pruning for healthy growth

Emerald Ash Borer

Emerald Ash Borer (EAB) is an aggressive beetle in Asia, which has caused widespread destruction of ash trees in North America, including Ontario. Adults are EABS metal green, about 8-14 mm long, beetles. They put their eggs on the bark of ash trees, and when the larvae hatch, they burrow in the inner bark of the tree and live by the flood – the tissue responsible for transporting nutrients. This matters the ability to move water and nutrients in the tree, and eventually lead to the death of the tree, often within 2 to 4 years of infection within 2 to 4 years.

There are indications that your ash tree can be infected with emerald ash borer, which includes thin or dying crowns, yellow or brown leaves in the growing season, bark division, and the presence of the exciting hole for exclusion of about 3-4 mm wide deformed on the trunk and branches where adult beetles have appeared. You can also see the tunnels on the tunnels under the bark tunnels on the bark. Woodpecker injury, where the bird is the bark in search of larvae, is another common indicator.

To prevent EAB infection, it is necessary to avoid the transmission of ashes or logs from infected areas to non-irritated people, as Beetle Wood can cause hiccups. Maintaining the health of the overall tree through proper watering, mulching, and fertilization can help trees resist stress, but it does not prevent infection in itself.

For already high-risk trees, systemic pesticides can be effective when used quickly. Trench injections or trenches in the soil, such as Emmacin-Benzoat or Imidacloprid products, can protect the ash trees by killing them in the soil, larvae, and adults. It is best to consult a certified arbist for diagnosis and treatment options, as time and application methods are important to succeed. In severe cases where trees are heavy.
