Experts Discuss Insecticide Options for Emerald Ash Borer Tree Care

Emerging challenges in managing the Emerald Ash Borer (EAB) were front and center at the recent informational meeting held by Minnesota Agriculture for Cass, Isanti, and Kanabec Counties. A key focus was the financial burden faced by homeowners needing to remove infested trees, particularly those on limited incomes.

During the meeting, officials highlighted a relief grant introduced last fall, aimed at assisting governmental units with EAB removals. However, the discussion revealed a significant gap in support for individual homeowners, who often struggle to afford tree removals. “We still don’t have great answers for that,” acknowledged one speaker, emphasizing the ongoing challenges for those with tight budgets.

In addition to financial concerns, the meeting provided valuable insights into effective treatment options for EAB. Experts recommended the use of emoectin benzoate, a chemical commonly employed by tree care professionals, particularly for large mature trees. This treatment is applied via trunk injection and has shown the most effectiveness based on research. The average cost for homeowners to protect their trees is approximately $10 per diameter inch, translating to around $150 for a 15-inch tree every two years.

As communities grapple with the impact of EAB, the need for accessible resources and financial assistance remains critical. The meeting underscored the importance of continued dialogue and support for homeowners facing these challenges, as well as the need for effective pest management strategies moving forward.
