Invasive Plant Workshop in Montgomery County

Extension to Host Workshop on
How to Fight Invasive Species

     Some exotic plants are invasive weeds that form expanding populations on our landscape, making management of timer, wildlife and other natural resources a challenge.  These invasive exotic plants can displace native plants and associated wildlife, and can affect fire and water flow.  The rapid and effective dispersal characteristics of these invaders make them extremely difficult to eliminate.  

     Because of the challenges invasive species present to our natural spaces, University of Illinois Extension Unit 18 is hosting a prairie stewardship workshop on September 19 from 9 am – 3 pm at the Montgomery County Extension Office in Hillsboro. The workshop will also include on-site field demonstrations at Bremer Sanctuary.

     The program will describe the more common and troublesome invasive exotic plants in central Illinois and current methods being used to control them. The program will include talks on identification of local invasive exotic plants and animals, and methods of control, how herbicides work and how to select the right one, and herbicide safety and application techniques. In the afternoon, the program will conduct on-site field demonstration at Bremer Sanctuary.

     The cost for the program is $10 per participant and includes materials. In order in insure there are adequate materials, those interested in attending are asked to contact the Montgomery County Extension office at 217-532-3941, or they can register for the workshop on-line at:  Once on the site, go to the “Register Online” area at the right hand side and click on the event.

     University of Illinois Extension provides equal opportunities in programs and employment. If you need a reasonable accommodation to participate in any of our programs, please contact our office.

Invasive beetle confirmed in 3 Arkansas counties

HOPE, Ark. (AP) - State agriculture officials say an insect native to Asia that kills ash trees has been confirmed in three Arkansas counties.

The Arkansas State Plant Board and the Arkansas Department of Agriculture say the emerald ash borer has been found in Hot Spring, Clark and Nevada counties. The insect arrived in the U.S. around 2002 and has killed about 50 million ash trees since then.

Officials say the insect has now been confirmed in 24 U.S. states and two Canadian provinces.
Female emerald ash borers lay eggs on the bark of ash trees. Once the eggs hatch, the larvae bore into the bark, eventually killing the trees.

Officials say the best way to avoid the spread of the insect is to not move firewood from place to place.

Issue no. 8 of the Home, Yard & Garden Newsletter


Guignardia Leaf Blotch

Guignardia leaf blotch is a fungal disease that affects many Aesculus species.  In Illinois, this disease is commonly seen on the common horsechestnut (Aesculus  hippocastanum).  Symptoms begin as rapidly enlarging, irregularly shaped,  water-soaked areas.

Modified Growing Degree Days (Base 50°F,  March 1 through May 15)

Insect  development is temperature dependent. We can use degree days to help predict insect emergence and activity. Home, Yard, and Garden readers  can use the links in this article along with the degree day accumulations to determine  what insect pests could be active in their area.

Illinois  Invasive Plant Phenology Report

Several invasive plant experts  from around the state have started a new series of reports focusing on the  phenology of invasive plants in Illinois. The intent of these reports is to  provide an update on the development of invasive plants across the state of  Illinois -- what plants are in bloom, leafing out, setting seed, or senescing in  different areas of the state.

Thousand  Cankers Disease Confirmed in Indiana, Fungus Found on Insect Other than Walnut  Twig Beetle

The Indiana Department of  Natural Resource issued a press release on Friday, June 20 announcing the  detection of Thousand Cankers Disease in Indiana. Indiana joins Maryland, North  Carolina, Ohio, Pennsylvania, Tennessee, Virginia, and eight western states  with the disease.

Palmer Amaranth -- A New Weed to Watch For

Ask any cotton farmer what has been their biggest weed  problem of recent years and they will all likely tell you the same:  Palmer amaranth (Amaranthus palmeri).  This  plant has put some southern farmers out of business. Midwest farmers are now or  will soon be well acquainted with this fast growing and yield robbing species  as it is moving northward across the Midwest.

Japanese Beetle

Japanese  beetle adults are present throughout Illinois. Robert Bellm, Extension  Educator, reported their presence in Madison County, and Ed Nangle, Chicago District  Golf Association, reported their presence in Cook County. Last week in this  newsletter, we predicted low numbers in the northern half of the state due to  the extended deep soil freezing last winter.

Fall Webworm

Fall  webworm is named for infestations that occur in the northern part of the United  States only in late summer to early fall. In the southern half of the United  States, including the southern half of Illinois, fall webworm has an additional  generation in early summer. This first generation of fall webworm is now  feeding in southern Illinois.
