Combating the Emerald Ash Borer Threat

With potential damage to Denver trees in the tens of millions of dollars, treating and preventing infestation of the emerald ash borer is a top priority of arborists and foresters area-wide. While traces of the beetle—which has no natural predators—haven’t been seen in the city yet, the beetle has appeared in Boulder and Longmont, and the Denver city forester says the time to start preventive treatment is now. To head off infestation, Denver Parks & Recreation has launched the Be a Smart Ash campaign to educate property owners of the dangers posed by the beetle. Donovan Arborists supports the campaign enthusiastically and offers the following advice to homeowners and businesses with ash trees on their property.

Be A Smart Ash: Protect Your Trees from the Emerald Ash Borer

The time to treat emerald ash borer and other pest infestations and diseases in your landscape is before they occur. And early spring is a good time to start with a program of Integrated Pest Management to keep your trees and shrubs healthy and thriving.

What is Integrated Pest Management? 

Integrated Pest Management (IPM) is a holistic approach to the long-term health of your plants. It’s a USDA-sponsored program designed to improve economic benefits in plant management while reducing human health risks and adverse environmental effects. It extends to all forms of pest management from insect damage to plant diseases in both agriculture and urban landscapes.

Putting Integrated Pest Management to Work for You

At Donovan Arborists we believe in being proactive in preventing insect infestations and disease outbreaks in our customer’s trees and shrubs. We understand that people have different views when it comes to the use of pesticides on their property. Together with your input, we develop a plan that determines the actions taken. We ensure your landscape is healthy and that the direct environment around the plant is not stressed. Stress contributors (soil, water and nutrient levels) are effectively managed and kept in balance, reducing the risk of pest and disease infestation and the need for traditional pesticide use over time.
