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 […]
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 […]
Early Spring Insect Update
Not surprisingly, the early spring warm-up has resulted in a frenzy of early season insect activity. We were out in the field earlier this week to get a handle on just how far ahead insect activity may be this year and we were somewhat exasperated by what we found… Billbugs Billbugs are out in […]
Black Cutworm and Armyworm Moths Are Early Arrivals in 2012
The mild winter experienced throughout the midwest has affected the arrival of our early season moths. Recent reports of both armyworm and black cutworm adults throughout the state signal an early arrival of the caterpillars. The first order of business for these moths is to mate and lay eggs. Golf course superintendents and athletic field […]
Crabgrass is Now Germinating at Most Indiana Locations
The GDD Tracker website (sponsored by the MRTF and Purdue University) is predicting that crabgrass is now germinating at most Indiana Locations (see figure below). The GDD Tracker estimated that crabgrass germinated in Lafayette, IN after Wednesday this week and I was able to confirm this by identifying newly germinated crabgrass (see figure below) both […]
When Will Crabgrass Germinate?
With the rapidly warming weather, several are asking “When will crabgrass germinate?” The reason this is so important is because preemergence herbicides used for the control of crabgrass must be applied prior to emergence (except dithiopyr (Dimension) which can be used postemergence on crabgrass up to 1-tiller). There are several different ways to try and […]
Unwinter, Poa seedheads and Growing Degree Days, Oh MY!!!
As the “un-winter of 2011-2012” rapidly winds to a close golf course managers are already bringing their playing surfaces into peak form. For those managing putting surfaces containing annual bluegrass (Poa annua) this means addressing concerns that seedheads are affecting surface smoothness. With the lack of snow cover this past winter, the seedhead season is […]
Get your motor running: Crabgrass control adjustment
With warm temperatures this winter many are questioning how to adjust their turf management practices in 2012. In the past 90 days, Indiana temperatures have averaged 3-4 degrees warmer than normal. The forecast also shows that we will likely continue to be warmer than normal during the next 30 days. Although I do not foresee […]
Purdue Turf Bowl Teams Place in the Top Ten in Las Vegas!!!
Purdue students continue to protect their “turf” among the rise of new competitors at the 18th Annual Collegiate Turf Bowl Competition hosted during the 2012 Golf Course Superintendents Association of America (GCSAA) International Golf Course Conference and Show in Las Vegas, NV. The three and one-half hour competition this year challenged student’s knowledge of more […]
2012 = Same Pests But Earlier ETA
With the very mild winter that most of Indiana experienced so far, we are being asked about its effect on insect populations for this year. The consensus among turfgrass entomologists is that although insect populations were probably not especially hurt by low temperatures this winter, they probably have not benefitted that much either. Insect pests […]

Imprelis Herbicide Injury: 2011 PPDL ‘Host’ List
We have received questions pertaining to susceptibility of plants to Imprelis. We do not have a list of “susceptible vs. not susceptible” plants because we do not know exactly which plants might be affected under certain growing conditions. However, based on our experience in the PPDL this past summer the list below contains the names […]
