Emerald Ash Borer 101

An introduction to a “Bug Without Borders” and effective management options

SLIDE 2

What is EAB?

Emerald Ash Borer (Agrilus planipennis)
Non-native invasive insect with NO natural

predators in Ontario.

Approx 3.5mm wide and 8-15mm long
Originated in Asia
Came to N. America via shipping crates and

dunnage.

First noticed in 2002 near Windsor, ON

SLIDE 3

Regulated by the Canadian Food Inspection

Agency.

Multi-agency approach involving the Ontario

Ministry of Natural Resources (OMNR), Canadian Forest Service and the Ontario Ministry of Agriculture.

EAB affects everyone and comes with a price

SLIDE 4

EAB attacks all species of true Ash trees (genus Fraxinus)

White Ash Green Ash Black Ash

North American hosts

What trees will EAB attack?

EAB is predicted to kill 99.9% of all Ash trees if nothing is done!!

SLIDE 5

A Deadly Cycle

SLIDE 6

What are the symptoms?

SLIDE 7

How does EAB move around?

Natural spread

 adult beetles can fly up to 3km but typically only 100m

Human assisted spread

Firewood Nursery stock Pallets Logs

SLIDE 8

What’s the BIG deal?!?

Toledo, Ohio - difference from 2003-2009 Ottawa, ON - 2011

SLIDE 9

How fast will trees decline?

2-4 years with

lighter populations

1-2 years with heavy

EAB populations

As quickly as one

growing season!

Treatment options?

Inject with a systemic insecticide.
TreeAzin product of choice
Bioinsecticde with an active ingredient

extracted from Neem tree seeds.

2 year protection against EAB.
Poses minimal risk to:

applicators, bystanders, and pets bees, birds, and mammals soil and aquatic ecosystems

SLIDE 17

How effective is TreeAzin?

SLIDE 18

How long do we keep treating?

SLIDE 19

So what’s everyone else doing?

City of Peterborough

Peterborough’s Emerald Ash Borer Management Plan which will guide the City over the next 10 years includes:

Inventory, Monitoring and Assessment;
Treatments;
Tree Removals;
Tree Planting;
Wood Waste Disposal; and
Public Education and Communication.

SLIDE 21

Primary objectives of plan

Ensure Public Safety and

Minimize Liability

Mitigate the Loss of

Significant Ash Trees

Maintain the City’s Tree

Canopy

Provide Public Education and

Awareness

SLIDE 22

What are the options?

Option #1 – Do Nothing and REMOVE everything Option #2 – Treat Everything Option #3 – Hybrid Plan - treat the best, remove the rest

SLIDE 23

Managing the fiscal hit

The Hybrid Plan has been adopted by The Society of Municipal Arborists as the best management option.

SLIDE 24

Continue to manage the inherent risk that your trees

present.

Continue taking steps to mitigate the impending

liability brought on by EAB.

Continue to develop and adopt an effective and

efficient EAB Management Plan.

Where do we go from here?

Continue to be good stewards of our urban forest!
