Summer 2015 - The Grazing Gazette Ag Newsletter

An Agricultural Newsletter IN THIS ISSUE:

Greetings Agrarians,

Summer has finally arrived. Tobacco is being set, hay is being cut, and corn and soybeans are sprouting. The year has been unpredictable with weather, but let’s hope we have a mild summer with good rainfall.

I know things are busy during production season, but take a look at some of the upcoming field days that are occurring in our area.

I will be traveling for much of June and July attending state meetings, national meeting, and taking a study tour. If you need immediate assistance for crop or livestock needs, please call the Grant County Cooperative Extension Service 859-824-3355. For all other inquiries I will be available through email lindie.huffman@uky.edu.

The Grazing Gazette

by Lee Townsend, Extension Entomologist, Lynne Rieske-Kinney, Professor, Forest Entomologist, University of Kentucky College of Agriculture What is the status of the emerald ash borer in Kentucky?

The first infestations of the EAB were confirmed in May 2009 from sites in Jessamine and Shelby counties. Visit the Kentucky EAB site for the latest information. The first infestations of the EAB were confirmed in May 2009 from sites in Jessamine and Shelby counties. Visit the Kentucky EAB site for the latest information. http://pest.ca.uky.edu/EXT/EAB/welcomeeab.html What makes an EAB infestation "official"?

The initial confirmation of EAB in a county must be based on the collection of a life stage of the insect– usually a larva or an adult.

Larvae or adults collected from ash wood should be preserved in alcohol.

Specimens are sent to the Animal Plant Health Inspection Service for confirmation before the insect is considered to be officially present. An exit hole or larval gallery in wood is not enough to make a positive identification for a new county record.

What happens after an identification is confirmed?

The county will be placed under quarantine to prevent movement of infested articles and a survey will begin to determine the extent of the infestation. A management plan will be developed after the extent of the infestation and the density of ash in the area has been determined.

On June 24, 2009, a quarantine was issued to include Boone, Bourbon, Campbell, Carroll, Fayette, Franklin, Gallatin, Grant, Harrison, Henry, Jefferson, Jessamine, Kenton, Oldham, Owen, Pendleton, Scott, Shelby, Trimble and Woodford counties. The quarantined area includes counties with confirmed infestations, those close to the infestations, and counties with a high density of ash trees.

What does a quarantine accomplish?

The quarantine prohibits “regulated articles” from being moved outside the quarantine area without a certificate or limited

permit except under certain conditions. A regulated article may be moved by the U.S. Department of Agriculture or the Kentucky Department of Agriculture for experimental or scientific purposes; may be moved in an enclosed vehicle or completely covered to prevent access by the emerald ash borer (through Sept. 30); may be moved directly through the quarantined area without stopping except for traffic conditions and refueling; may be moved if it is stored, packed or handled at locations that do not pose a risk of infestation; and may be moved if it has not been combined or commingled with other articles.

"Regulated articles" are defined as the emerald ash borer, hardwood firewood, ash nursery stock, green ash lumber, other ash material, and any other materials that present a threat of artificial spread of the emerald ash borer. Regulated articles that have not been treated can be moved out of the quarantine area during the non -flight season (October thru March) with a limited permit. Both the shipper and receiver must have compliance agreements and the processing mill must process the materials by April 1.

The EAB is in Kentucky to stay and its distribution in the state will continue to expand. A sound plan for living with it has been developed based upon research findings and experiences from older infestations. The challenge is to do everything we can to make the plan work and learn to manage the EAB. What trees does the EAB attack?

All species of ash (Fraxinus) in landscapes, forests, and woodlots in eastern North America are susceptible to attack by the emerald ash borer. Females may prefer to lay eggs on stressed trees but healthy ones also can be infested. Host size does not appear to be a constraint either, larval galleries have been found in trees or branches as small as 1 inch in diameter.

What does the EAB do to ash trees?

As they feed under the bark, EAB larvae destroy the tree’s water and nutrient conducting tissue. This reduces water and nutrient flow to the canopy and causes thinning above infested portions of the trunk and major branches. Dieback in heavily infested trees usually starts at the top with one-third to one-half of the branches dying in one year; most of the canopy will die within 2 years of the first appearance of symptoms.

What are signs of an EAB infestation?

The following general characteristics may be caused

by EAB, other borers, stress, or physical injury:  - Thinning of canopy  - D-shaped 1/8" exit holes in the bark  Serpentine-shaped tunnels under bark  - Young sprout growth at base of tree  - Woodpecker activity  - Vertical splits in bark How do infestations spread?

Normal flight spread of the EAB is between one-half to two miles a year so natural spread tends to be relatively slow. Unfortunately, movement of infested ash wood can result in jumps of hundreds of miles.

Firewood has been a major means of transporting EAB, especially by hunters and campers. Slowing the spread can buy time to develop and implement management plans based on ash components of wooded areas and to take advantage of strategies that might be developed through current research. Is the EAB easy to recognize?

Adults are distinctive dark metallic green beetles that are about 1/2 long and about 1/8 inch wide. They may be found resting or

feeding on ash leaves during May and June. They emerge through distinct D-shaped holes in the bark. The larvae may be found tunneling under bark from July thru October. Fortunately, they are relatively easy to distinguish from native ash borers.

Should I begin to use insecticides to protect my ash trees from the EAB? Treatment is an individual decision based on specific conditions.

However, preventive insecticide applications generally are not recommended if known infestations are not within 15 miles of your location. If there is no quarantine for your county, identify ash trees on your property and keep them as healthy as possible through proper fertilization and watering. Watch trees closely for signs of EAB infestations. Stay informed about the situation in your area.

Are insecticide applications worthwhile if nearby infestations are discovered?

Most insecticides currently registered for EAB control must be applied every year. Treatments may be worthwhile to protect very valuable trees or to keep individual trees alive until nonsusceptible replacement trees are large enough to provide satisfactory shade. Detailed information on control alternatives is available at: http://pest.ca.uky.edu/EXT/EAB/EABcontrol.pdf What is the life cycle of this borer?

The EAB can have a one– or two-year life cycle, development time decreases and the number of borer larvae per tree increases. In Michigan adults begin emerging in mid to late May with peak emergence in late June. Females usually begin laying eggs about 2 weeks after emergence.

Eggs hatch in 1-2 weeks, and the tiny larvae bore through the bark and into the cambium - the area between the bark and wood where nutrient levels are high.

The larvae feed under the bark for several weeks, usually from late July or early August through October. The larvae typically pass through four stages, eventually reaching a size of roughly 1 to 1.25 inches long. Most EAB larvae spend the winter in small chambers in the outer bark or in the outer inch of wood.

Pupation occurs in spring and the new generation of adults emerges in May or early June, to begin the cycle again.
