Purdue Turfgrass Research Report Available On-Line
The summary of our turfgrass research in the year 2004 is now available at http://www.agry.purdue.edu/turf/report/2004/index.htm. The overall goal of our research program is to minimize inputs while maintaining turf quality, minimizing costs, and further protecting our environment. Our research summary contains over 40 reports of on-going research at Purdue University. The report is a cooperative effort […]
Turf Field Day Held July 26
Thanks to everyone who attended and helped make the 2005 Midwest Regional Turf Field Day a success on Tuesday, July 26. A hot steamy day with thankfully a brisk breeze greeted the almost 750 attendees. Attendees had the opportunity to view the latest in turfgrass research, visit with Purdue specialists, see the most modern equipment […]
Summer stress of Poa annua, Poa trivialis on Golf Courses
Persistent air temperatures of 90F and soil temperatures greater than 80F combine with high humidity and adequate rainfall (in some areas) is doing in the Poa annua (annual bluegrass)and Poa trivialis (rough bluegrass)on golf courses. After a week or two of these conditions, Poa annua greens and fairways will start to thin and die in […]
Summer stress of Poa annua and Poa trivialis in Lawns and Sports Fields
Persistent air temperatures of 90F and soil temperatures greater than 80F combine with high humidity and adequate rainfall (in some areas) is also doing in the Poa annua (annual bluegrass)and Poa trivialis (rough bluegrass)on lawns and athletic fields. Patches of these fine-bladed grasses seemingly die overnight with even a minimum of drought stress. Though these […]
Perennial Ryegrass Looking Exceptionally Bad Right Now
Dollar spot, pythium, brown patch, rust, and perhaps other diseases are ravaging perennial ryegrass lawns currently (See the attached (undoctored!) photos). Turf performance in July and August is the main reason I don’t recommend perennial ryegrass for lawns in Indiana. Perennial ryegrass requires more irrigation, more fertilizer, and more fungicide applications than my preferred grasses, […]
Japanese Beetles are in Full Force
The first Japanese beetles of the year were observed in central Indiana on June 22 and have since come out in full force. They are being reported in large numbers from many places throughout the state feeding on their favorite plants. Plants particularly at risk include those that have been recently transplanted or those that […]
Midwest Regional Turf Field Day on July 26
Don’t forget to register for the Midwest Regional Turf Field Day that will be held on July 26 at the W.H. Daniel Turfgrass Research and Diagnostic Center in West Lafayette. This is a great opportunity for turf professionals to view the latest in turfgrass research, talk to Purdue specialists about turf and ornamental issues, and […]
Establishing Turf in July
This is the toughest and most expensive time of the year to establish a lawn and waiting just four or five weeks to seed in the first half of August would be ideal. However, in some cases it must be done now and following are some tips to help: Success depends on irrigation and it […]
Overseeding creeping bentgrass into thinning Poa annua
Dry and hot conditions may unfortunately favor early exit of Poa annua from golf turf. However, there is a silver lining to this. Rutgers reported that overseeding creeping bentgrass directly into a Poa stand in summer is effective for gradual conversion when done July 1. Rutgers produced significant (>25% cover) of bentgrass within 12 months […]
Velocity for Poa annua control….Potential and Precautions
Velocity (byspribac) was registered for Poa annua control in creeping bentgrass last November, so this is the first summer of potential widespread use. As with all new pesticides, we’ll learn more of the finer details as we use it. We have a number of studies at Purdue currently and I just stopped at a course […]

Facts and Advice on Turf Survival in Drought
There are many questions about turf survival in drought with the on-going drought in most parts of the state. Though we understand many of the mechanisms of turf survival in drought, it’s hard to duplicate all of the potential situations on research plots across the country and it’s difficult to give definite “black and white” […]
Quicksilver Receives 24C Registration for Moss on Greens in Indiana
FMC’s QuickSilver T&O herbicide has just received special local 24(c) registration for control of silvery thread moss in putting greens in Indiana. Though Quicksilver (carfentrazone) is used widely as a quick knockdown contact broadleaf herbicide, it has good efficacy on silvery thread moss. The recommended rate for moss is 6.7 fluid oz/A (0.154 oz/1000 ft2 followed […]
Purdue Urban Landscape Study
Curious about your lawn and landscape? We need your help! We’re looking for volunteers from Tippecanoe and adjacent counties to participate in our landscape study. Scientists from Purdue University will: • Survey your lawn and landscape for insects, weeds, and diseases • Determine what type(s) of turfgrasses are present • Conduct a free soil test […]

This is a great opportunity for turf professionals to view the latest in turfgrass research, talk to Purdue specialists about turf and ornamental issues, and visit with […]
Early Dollar Spot Applications Make Sense
Dollar spot has arrived on golf courses. The standard mid- to late May fertilization of 0.75-1.0 lb N/1000 sq. ft. with primarily slow release N should have helped minimize some dollar spot. On golf courses with a long history of dollar spot, first and foremost review the fertilization practices and increase the annual N if […]
Update on Black Cutworm
Significant weather events from the south usually are responsible for the movement of the black cutworm moths into our area each spring beginning as early as March. Black light traps stationed throughout the state have failed to catch many black cutworms this year to date. This is good news for our industry and may spell […]
Maximizing Lawn Performance Under Drought
As low moisture conditions continue in Indiana and Indianapolis is already requesting volunteer reductions in water use, it is time to start preparing for a potentially serious drought. Generally, turf can survive 5 to 8 weeks of dry conditions without substantial thinning or death. However, poor soils, traffic, excess heat, low mowing and/or scalping, and […]
Interactive Turfgrass Identification Tool now available
After about 9 months of development a concept of mine has finally borne fruit. This week we rolled out the interactive, self-guided, online turfgrass identification tool, located at: http://www.agry.purdue.edu/turf/tool/index.html. Now you can probably identify the mystery grass in your lawn from the comfort of your own computer. If you still can’t identify it, you can always […]
