Helping Fall-use Athletic Fields
Fall use athletic fields are taking a beating right now. To help those fields, fertilizing aggressively with 1.0 lb N in September and again in October will help. Fertilizing is the most inexpensive but effective way to improve any sports field. Though it’s easier said than done, aerifying during extended breaks in practices or games […]
New Era begins for Ross-Ade stadium turf
The Purdue Boilermaker’s 60-35 win this past Saturday was not only the first test for the football program but also the first real test and a historic milestone for Purdue’s newly renovated field. The beginning of this season marks a new era in Purdue football as Ross-Ade stadium becomes the only Big-10 stadium with a […]
Crabgrass Problem Revisited
The tremendous crabgrass pressure mentioned in earlier Turf Tips deserves more attention and the most common question is “Why is it so bad this year?”. The obvious answer to this is the above average heat and humidity during July increased disease pressure and thinned or weakened turf. Crabgrass germinated in these new gaps and quickly […]
Gray Leaf Spot Update
There have been several reports of gray leaf spot outbreaks throughout Indiana and the lower Midwest during the past two weeks. The disease will develop over a broad range of environmental conditions (not just hot and wet). Our research results showed that the presence of inoculum is the disease-limiting factor north of the Ohio River. […]
Turf Field Day Held July 18
Thanks to everyone who attended and helped make the 2006 Midwest Regional Turf Field Day a success on Tuesday, July 18. A hot steamy morning with thankfully a brisk breeze greeted the almost 650 attendees. Attendees had the opportunity to view the latest in turfgrass research, visit with Purdue specialists, see the most modern equipment […]
Overseeding creeping bentgrass into thinning Poa annua
The recent heat 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 of […]
Summer stress of Poa annua, Poa trivialis on Golf Courses
Persistent air tempertatures 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 […]
Bermudagrass Takes Root in Ross-Ade and the South Football Practice Field
It is in some ways difficult to believe that it has been just over one month since the first “Big Rolls” of ‘Patriot’ bermudagrass were installed in Ross-Ade stadium on 6 June, 2006. The sod 42” wide rolls arrived on refrigerated trucks from the sandy coastal plain soils of Eastern Maryland. Some of you may […]
Midwest Regional Turf Field Day on July 18
Don’t forget to register for the Midwest Regional Turf Field Day that will be held on July 18 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 […]
Japanese Beetles: They’re Back!
The first Japanese beetles of the year were observed in central Indiana last week and now is a great time to review the biology and control of these pests. Japanese beetle adults pupate from larvae in late spring and begin emerging at this time of the year. We expect them to arrive in full force […]
Bermuda suppression in zoysia?
Bermudagrass is one of the most difficult species to control due to its extensive stolon and rhizome system, aggressive growth, and tolerance to management and environmental extremes. It is even more difficult to control selectively in another warm season grass, thus it can be a problem wherever zoysiagrass is grown as the desirable turf. Recent […]
More on Nematodes and Indiana Greens
As our nematode survey continues, more questions are being asked about nematodes, their damage potential, etc. Following is an update on the survey: Do not attribute all vague symptoms to nematodes. Nematode populations and symptoms are extremely complex and cannot be diagnosed by anyone other than a nematologist. In other words, don’t panic. […]
Red thread, pink patch, and dollar spot in lawns and roughs
Red thread and its close relative pink patch, are now appearing on home lawns (and golf course roughs) in the central and southern parts of Indiana. Red thread first appears as small (quarter to golf ball size) gray – tan colored patches in the turf. After extended dew periods, white – pink mold may be […]
Football Renovations Continue (Part 2)
Tremendous progress has occurred since our last update, 17 May, on the projects to enhance the football practice and game fields at Purdue University. These have been exciting times for all those associated with the Turf program as we have been able to witness three different turf renovation projects all occurring simultaneously. It has truly […]
Ross-Ade and South Football Practice Field Renovations – Update 17 May 2006
After nearly a week of steady rain in West Lafayette and across the region, work was finally able to continue on the Ross-Ade stadium and South football practice field renovations. The existing Kentucky bluegrass/perennial ryegrass turf in Ross-Ade was removed today with a “Koro” machine. The machine is essentially analogous to a milling machine used […]
Aerification Following Preemergence Herbicide?
In theory, a barrier of preemergene herbicide is created in the soil and limites emergence of crabgrass. Any gap in this barrier could allow crabgrass to germinate. This is why a uniform application of preemergence herbicide is required and practices like power raking or aerification are usually not recommended after application. However, research consistently shows […]
Pink Snow Mold Active
The cool wet weather the last two weeks is favoring Microdochium nivale, the pathogen that causes pink snow mold (sometimes referred to as Microdochium patch). The color of pink snow mold scars indicates the activity of the patch. Straw colored patches are usually inactive. However, a rust to orange colored band or ring indicates an active […]
