Burn Bans, Fireworks, and Turf
As of today, July 10th 2012, there are 85 counties in the state of Indiana that are reporting active burn bans (http://www.in.gov/dhs/files/burn-ban/). Many of these bans include the use of public and personal firework displays. Although these bans are in place and we are past July 4th, it may be necessary to survey sites under […]
Ground Moving with Tiny Migrating Insects
Whenever I give my ‘General Insect Pest’ presentations I include a couple of photos of chinch bugs and their nymphs. Usually I say something like “These are not pests every year in Indiana but can become troublesome in years when we have a drought.” Guess what? That is now! The dry conditions we are […]
New! Purdue Extension Website with Drought Information
A new website has been created to help homeowners and professionals find useful information concerning how to cope with drought. This page includes resources about crops, turf, landscapes and more. Visit www.purdue.edu/drought for more information.
My Lawn is Brown and Crunchy… Is it Dead? What do I do now?
The first day of summer/longest day of the year for 2012 has come and gone and just this past week a new National Drought Monitor Map was published (see below). The city of West Lafayette in Tippecanoe County has now fallen into the “Severe Drought” category. In fact 36% of Indiana is now in […]
Japanese Beetle Emergence and Management
Below is an e-mail conversation that may be of benefit to other turfgrass managers asking similar questions. Original message: From: Golf Courses Date: Friday, June 22, 9:30 AM To: Gibb, Timothy “Gibb, Timothy” <gibb@purdue.edu> Subject: Japanese Beetles Management in 2012 With the early spring we expected to see early Japanese Beetles. We did […]
2012 Imprelis UPDATE
A new publication, Imprelis Update: 2012 Field Notes on Injury and Recovery, was just developed by Purdue Specialists to address some of the many questions being asked about Imprelis in 2012 including: Did trees recover from Imprelis® injury? Are new symptoms being discovered? What Should I Do if I Suspect Imprelis® Injured Trees BUT I […]
It’s getting toasty out there! Update on drought and management adjustments
If you like your toast burnt and your bacon crisp, then you might be enjoying this weather. Most of Indiana has entered into drought officially as determined by the drought monitor (see map below). Maps are updated weekly and available at: http://droughtmonitor.unl.edu/monitor.html Indiana specific weather can also be found at http://iclimate.org/index.asp including maps like […]
Purdue Annual Turfgrass Research Report
As the green industry continues to have a large impact on Indiana and the nation, Purdue University has assembled an outstanding team of researchers, extension personnel, and educators that are dedicated to solving problems and helping meet the needs of Indiana residents. One segment of the Indiana green industry that continues to provide a significant […]
Should I apply an herbicide right now?
Here are some thoughts on summer weed control in non-irrigated areas during periods of drought: Herbicides are ineffective on drought-stressed weeds and can be damaging to drought-stressed turf, especially when temperatures are warm. My rule-of-thumb is that if the lawn is >50% green, then herbicides can be applied. Avoid the temptation to apply herbicides […]
Early Billbug Damage Reported Across the Midwest
This season continues to challenge our traditional thinking about insect seasonal ecology and management. Indiana and neighboring states are currently witnessing serious billbug infestations with late instar billbug larvae already present in the soil. This activity is easily 2-3 weeks ahead of normal. We advise all turf managers to take a close look at areas […]
Japanese beetle monitoring traps confirm early season in 2012
As anticipated, Japanese beetles are out early this year. The first beetles were captured in central Indiana during the week of May 14-18. (This is nearly a month earlier than most years.) We expect Japanese beetles to arrive in full force in this area within the next 2-3 weeks. Because we have never experienced […]
Time to Water?
With the heat and dry conditions most in Indiana are experiencing, many turf areas are starting to brown. Water is critical to the growth of all plants, not just turfgrass. Turfgrass leaves and shoots are comprised of about 80% water. A lack or water (rainfall or irrigation) will lead to a decrease in growth and […]
Grassy Weeds in Turf Planted Last Fall
Many samples have arrived in the Plant and Pest Diagnostic Lab the past few weeks with the common question of “What’s this grass in the turf I seeded last fall?”. Although there could be a host of answer to this question with annual bluegrass likely on the top of the list, most of what I […]
Don’t Forget to Sharpen Those Mower Blades
Sharply cut leaf blades increase turf health by improving recovery, decreasing water loss, and increasing photosynthesis. Lawns mown with a dull mower blade have poor aesthetics, heal more slowly and have greater water loss. Seedheads are present in many lawns right now and they are typically tougher to cut than the grass blades themselves. As […]
Assessing Spring Freeze Injury in the Landscape
As most gardeners have marveled, we’re having one of the earliest “spring” seasons this year, with woody plants and herbaceous perennials three to six weeks ahead of “normal.” And then, perhaps inevitably, “normal” spring frost and freeze visited. Being so much further along in their development, plants are quite vulnerable to damage. […]
Crabgrass Not Dead After Recent Frosts/Freezes
Despite some recent frosts and freezes across certain spots in Indiana, crabgrass remains unaffected and was not killed. Although crabgrass was not injured, other cold sensitive plants were such as volunteer tomato seedlings in my garden and my Japanese maple. Recent cold air temperatures cooled down our soil temperatures. Temperatures will be mild for […]
