    University of Illinois Home Yard and Garden newsletter is a great way to stay up on Illinois weed, disease and insect problems and management guidance.  With the below link you can sign up for direct emails notifications as well.


    Issue no. 9 of the Home, Yard & Garden Newsletter is now available on the Web. Point your browser to:


    White grubs

    White grub is a common name for the larvae of June beetles, chafers and Japanese beetles that feed on the roots of turfgrass.  The grubs can be found in the first 8 inches of soil beneath turfgrass.  They are white, C-shaped larvae, about 1 inch long and have 6 jointed legs attached close to their small brown head capsule.  Excessive root feeding by white grubs can leave turfgrass poorly anchored to the soil and can result in brown patches in a lawn that can be pulled back like a rug.  This can impact the aesthetics of a lawn and, in some cases, can make sports fields less safe for children and athletes.

    Nimblewill Noticeable During Hot Dry Conditions

    There have been a few recent calls about nimblewill (Muhlenbergia schreberi).  With the hot, dry conditions we have had  lately, our cool-season turfgrass growth has slowed, making warm-season  nimblewill growth more noticeable.  While  cool-season turfgrasses are dormant, nimblewill is actively growing and  enjoying the lack of competition.  This  unbalance can allow nimblewill to be a serious weed problem.

    Fire Blight

    I have received a few reports and questions regarding fire  blight on ornamental pears. Fire blight is a bacterial disease that infects  approximately 75 different species of plants, all in the Rosaceae family. Apples,  pears, crabapples, and ornamental pears are the most seriously affected  species. Other rosaceous hosts include cotoneaster, hawthorn, quince,  firethorn, and mountain-ash.

    Bacterial Leaf  Scorch – New Molecular Service Available

    It’s the time of the year that we start seeing bacterial  leaf scorch symptoms develop in central Illinois, and several samples have been  submitted that appear to be infected in the last few weeks. We are now offering  a molecular test for this pathogen, which will reduce the turnaround time, and  because it’s more sensitive than the previous ELISA test, ca be used any time  during the growing season when symptoms appear.

  2. update on tree inventory

    Associated Project(s): 

    Davey Tree's staff person is averaging 214 trees per day.  He started at University Avenue and is working his way south.  Currently he is at Armory Avenue.  Depending on the number of trees on campus, he could be done by the end of September.

  3. Update from Davey Tree

    Associated Project(s): 

    Here is an update on the progress of the tree inventory. Tree Count - 1,117


    I began on the north side of campus as we discussed in our kickoff meeting, and have started working south. I have completed most everything north of Green St. I will continue to work my way south next week. See attached file.

    Next week I will also start to do some data quality checks and will include some of that reporting in these update emails. If you have any questions, please let me know.

  4. Chancellor Jones sends congratulations letter

    Associated Project(s): 

    Chancellor Jones sent a congratulatory letter to the Tree Campus Advisory Committee, in recognition of their efforts to be recognized as a Tree Campus USA. That letter, as well as the letter from the Arbor Day Foundation, are attached here.

    "Congratulations to all of the Campus Tree Advisory Committee on your efforts that led to Illinois being recognized as a Tree Campus USA for a third consecutive year! This is a very visible example of what our campus commitment to environmental sustainability looks like in practice. I also know that this recognition is not simply a paper honor handed out to every university that applies, but only goes to universities that meet the exacting criteria set out by the Arbor Day Foundation. Thank you for all your hard work. The new tree on the Quad planted to celebrate this latest honor is going to be a great addition to the campus skyline."

  5. South Campus Afforestation Recommendation - Transmittal to the unit

    The recommendation was submitted to the NRES unit on March 2, 2018, by Morgan White. Jay Hayek, Extension Forestry Specialist in NRES, will be planting 2 acres of trees at the southwest corner of Race Street and Windsor Road.  The trees were purchased by the Champaign County Rotary Club.  There will be a wide variety of native oak and hickory species that come in 3 gallon containers and range in height from 3-6 feet.  The Students for Environmental Concerns (SECS) plan to assist with planting the trees, when they are delivered in early April.

  6. South Campus Afforestation Recommendation - Assessment with comments

    The iCAP Working Group (iWG) met on Feb 16, 2017. They supported the South Campus Afforestation recommendation. Their official comments for this recommendation was:

    "The iCAP includes an objective to add 50 acres of trees on campus, and this SWATeam recommendation suggests one potential location. The iWG suggests the College of ACES work with the Campus Master Planning committee to identify appropriate locations for additional trees. Another option to consider is parallel to the Embarras River."

    See attached the iWG assessment complete with comments from all the iWG members.
