Where are EAB found?

The emerald ash borer (Agrilus planipennis) is a destructive wood-boring pest of ash trees (Fraxinus spp.). Native to China, Mongolia, North Korea, South Korea, Japan, Taiwan, and the Russian Far East, the emerald ash borer beetle (EAB) was unknown in North America until its discovery in southeast Michigan in 2002.

What is an EAB quarantine?

The quarantine prohibits the entry into California of EAB and its host plants originating from any area where an EAB infestation exists. The Emerald Ash Borer is a wood-boring invasive beetle native to Asia and causes damage to agricultural and natural resources.

Is Emerald Ash Borer in Minnesota?

With nearly 1 billion ash trees in the state, the spread of EAB will have a serious impact in Minnesota. And although frigid winter temperatures in northern Minnesota may help to slow the spread and survival of EAB, cold won’t stop it completely.

Where can the Emerald Ash Borer be found in Minnesota?

The Minnesota Department of Agriculture (MDA) has confirmed EAB in Freeborn County. There are now 28 counties in the state with EAB. The new detection was found near the city of Alden, MN. The MDA has enacted a quarantine to limit the movement of firewood and ash material into Minnesota and out of infested counties.

How do you prevent EAB?

The most effective way to prevent EAB is to have prevention products injected into the trunk. Due to the complexity of this, it is recommended to hire an arborist to inject ash tree trunks in late May or spraying the trunk and foliage with insecticide in early June and again in early July.

What does the emerald ash borer do to the trees?

The larvae bore into the ash tree and feed under the bark, leaving tracks visible underneath. The feeding disrupts the tree’s ability to transport water and nutrients, resulting in dieback and bark splitting.

How far can you transport wood?

As a very general rule of thumb, 50 miles is too far, and 10 miles or less is best. Visit our Firewood map to help you figure out how far is too far in your area. In many states there are rules, regulations, and quarantines that clearly state how far is too far.

How much does it cost to treat an ash tree?

An average cost of treatment is approximately $11.00 per DBH. Dose rate of formulation and cost are determined by your tree’s diameter at breast height (DBH). Starting at 4½’ up from the base of the tree, measure the circumference of the tree’s trunk in inches with a measuring tape.

How did the emerald ash borer get in the US?

Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia.

What time of year do you treat ash trees?

This treatment process usually begins in late June or early July depending on the weather. According to university research, most EAB larvae begin actively feeding in ash trees around mid-July in this part of the country.

What tree does the EAB infest and why is it difficult to detect?

This guide is intended to assist field personnel in identifying life stages of, and damage caused by, emerald ash borer (EAB) (Agrilus planipennis Fairmaire). This difficult-to-detect insect causes symptoms in ash trees similar to those caused by many other abiotic and biotic causes.

Can I treat my ash tree myself?

Can I treat an ash myself or do I have to call an arborist? If your ash is smaller than 47 inches around the trunk at chest height [i.e., 15″ diameter at breast height (DBH)], you may be able to treat your ash tree yourself.

What should the base temperature be for EAB?

For EAB a base temperature of 50° F is used and the following are estimated thresholds for EAB activity: Current base 50° F degree day accumulations for Minnesota are available from US degree-day mapping calculator. What is EAB and how does it spread?

How to report emerald ash borer in Minnesota?

You can report EAB to the Minnesota Department of Agriculture several ways. or by leaving a detailed phone message at 1-888-545-6684. . account and submit a report. What are the Common Myths about EAB?

When was EAB first discovered in the US?

EAB was first discovered in North America in Michigan in 2002, and has now spread to many other U.S. states and some Canadian provinces (EAB in North America ). In Minnesota, EAB was discovered in 2009 in St. Paul, and a year later in Minneapolis and southeastern Minnesota.

What can be done to slow the spread of EAB?

Slowing the actual spread of EAB may mean economic viability for cities that are affected. If nothing is done to slow the spread, EAB can kill all area ash trees in a very short time. Slowing the spread means a city can spend $1 million a year on ash tree removal for eight years, instead of spending $8 million in one year for all the dead trees.
