It has been a hectic start! And Summer has not disappeared – yet!

A summer finish that seemed somewhat timid has not completely let go as we currently stand – temperatures in the mid 80’s mean that there is still a bit of care required to avoid getting into late season trouble. Aeration cores have been flying along with sand topdressing to help summer recovery processes – critical to many golf courses who retain quality putting surfaces through the summer seasons.

Rust abounds and I would expect some issues with dollar spot to still exist, although the drying conditions may limit the severity of the issues. Insect activity and the resulting digging has not started to fire up too intensely but it should arrive at some stage soon. Leaf fall has begun for many as Maple trees start to turn color and create a mess at the same time – it is the time of year for it to happen so surprise should not be one of your expressions in regards to this.

As for ATI students, they have been busy – classes have returned with somewhat higher number – a good thing though we would like more! The students have made a trip to Columbus to visit the OSU golf course facility during the event week, the Scotts Company in Marysville to see how fertilizer is made and also to the Ohio Turfgrass Foundation Research Field day – where they got to see the latest research at from the OSU Turf program. Following that the students were involved in the Turfgrass Scholarship Fundraiser on September 14th where they carried bags, interacted with alumni who came from all over, and some even managed to get some golf in. The students used the research green as a stop for the longest putt competition which was won by current OTF president Jason Straka who dropped a 40ft bomb with his first putt! The event raised over $17,500 for scholarships and we will look to build on that for next year – we are very grateful for everyones support both on the day and in the run up to the event.

The turf club has elected a new board of officers and students are preparing for trips to both OTF and GIS where they will man the OSU ATI Turfgrass Booth and meet our ever expanding alumni network. Finally Dr. Raudenbush and Dr. Nangle combined to purchase a greens roller for the students to practice on the putting green and make sure they know the intricacies of using such a piece of equipment – no one has crashed it yet!

As always if there are questions or queries dont hesitate to contact us! Enjoy the fall – whenever it arrives – Go Bucks!

Scholarship Golf Outing

Many of you have been waiting with bated breath for the announcement – here it is!

The annual golf outing in aid of student scholarships at ATI has been announced and the date is September 14th with a shotgun start at 9.30am – The annual event helps to fund incoming and current students and is a vital source of funding for students coming from families who have never had an opportunity for third level education previously.

Opportunities for hole sponsorships, door prizes and raffle items are available. Registration for players is expected soon with a 4 man team costing $320 and a per player price of $80. If there are any questions don’t hesitate to contact either Dr. Raudenbush ( or Dr. Nangle (

Thanks and looking forward to seeing you there.

The heat is literally ON

Summer has certainly arrived as temperatures rapidly went from enjoyable to decidedly uncomfortable with the current nighttime lows in NE Ohio hovering around the dreaded 70°F mark and concern rises about the arrival of the dreaded Pythium word. As of 6-13-17 the moisture has been limited with this hot spell (in reality it has been more hairdryer like) however with thunderstorms forecast and an increase in atmospheric moisture accompanying that then problems are certain to follow. As we get ready for the 100 days and start the countdown to August 15th remember – no rash decisions!

To help your self aim to vent or poke holes with non invasive pencil tines as much as possible – getting oxygen into the rootzone (which we hope is not compromised with spring rains) is critical to overcoming the issues. Further to that ensuring the plant protectant processes are on time and covering the expected issues is going to be critical at this time of year. Do not get behind the game early on turf conditions as summer is a very hard time to recover from problems. Further to that water management and ensuring maintenance conditions are not too stressful will be critical to help get the summer golf season off to a good start – so watching mowing heights, roller types and reducing inputs from a fertility standpoint will need to be given consideration. Finally – it is starting to get into insect activity time so using the model systems will be critical – if conditions stay hot and dry like this it could be a long summer!

Ensure staff are well hydrated and also protected from sun issues at this time also – they are your most valuable asset.  Good luck out there!


The summer has started!

This week has really introduced the heat for the year and those of you with bentgrass have probably been pretty darn happy – the wait is over – kind of! (A cool down will come). However  soil temperatures have now started to climb into the upper 50’s on average – and that is critical – measuring soil temperature at 12pm is not a good indicator of the reality of soil temperatures. This means timings for issues such as DMI treatments are now getting extremely late.

Further to that we are now most decidedly beyond the use of ester based formulations for broadleaf weed control and froma  safety standpoint amine formulations will be most appropriate going forward. Issues have not been to intense so far but managing water may be critical for the next short period of time – temperatures, high winds and turfgrasses that may be juvenile will be prime for problems. Trial season has begun for many of the turf team and so expect to see results running through the summer as well as the OTF Field Day on August 29th and trial data at Bob O’Link for vendors day on August 13th

Finally with this current blast of heat – make sure that all the crew are fully hydrated and also sufficiently protected against sunscreen. Good luck out there!

Trials initiated 5-17-17 at Bob O’Link in Avon, OH – see the results on August 13th!

End of the semester countdown

The end of the semester is coming up and students are getting ready for the final exams at ATI. All of our turfgrass students have had internships since late last year and places as far flung as Nevada, Illinois, Ohio and West Virginia are all on the list for students internship sites. Students have been out with Dr Raudenbush both at Hawks nest and around the state gaining insight into the industry as it wakes back up after winter (Picture 1). Dr’s Raudenbush and Nangle are getting ready to put out research trials both at Hawks Nest and in the Cleveland area so expect to see us out and about this summer. The year has been a busy one for all and we are expecting a strong incoming class for next August / September. To that end – make sure and provide us with your internship opportunities early and provide an educational plan for the internship if you really want to compete.


OSU/ATI students were in Columbus with Dr. Raudenbush and the Columbus Crew with field managers Weston Appelfeller this week (4-20-17)

Trial focuses will include moss control options, some plant health work and projects looking at water management strategies. We are also looking forward to releasing information about our scholarship golf outing with strong hopes of building on last years successful event.

Things to watch for in the near future – dandelion activity is in full flow, crabgrass germination is beginning to grab hold state wide with the only exceptions being on the lake in the northern part of the state. Furthermore courses in the northern part of the state would want to think about finishing and early season DMI applications up as time is starting to run out – rapidly!

Hurry hurry hurry

Rather incredible to think but based of the GDD tracker for people in northern Ohio time is now getting close to being passed optimum for both pre-emerge applications and applications of materials for seed head control – it also means golf season is just around the corner. Managing very wet soils and reducing early season wear and compaction is going to be difficult for many for the next month and so patience will be critical. Further to that – communication with memberships and golfers will be important this week as they lay their eyes on the beauty of Augusta.

Issues on the disease front seem to have been limited so far this spring – certainly there were no reports of Typhula spp. and it seems with the melting of snow and warmer temperatures in both January and February, Microdochium nivale has also failed to make much of an impression. Some activity has been noted with Rhizoctonia showing up around the ATI campus and also Laetisaria fuciformis showing up on slow growing lawn height turfgrasses. Its early in the season but scouting and staying on top of issues now will help for the rest of the summer!



Old man winter returns

The rush to summer may have slowed somewhat late this week, sightings of red thread were given last week and snow mold seemed to have taken to the bed for another year with highs running into the 60’s and 70’s. That however changed with snow in Northern Ohio in particular which followed some very stormy and heavy weather. The cold temperatures have indeed cut the progress on the growing degree days but this will be only a momentary slow down. Reports in the Cleveland area this week were that Poa annua seedheads had emerged on south facing slopes. The hope is that drying will occur soon and allow for applications to be made as people battle to manage the timing. The month of February saw many courses draw extremely unusual numbers of golfers and certainly will have been a help to start the year off – the concern is that there may be other issues such as diseases and insects that will have benefited from the early warm temperatures – scouting will be required. Winter annual weeds are certainly beginning to show up also – purple dead nettle and chickweed both emerging after the cold winter – activity is certainly ramping up early!


Old man winter returned with a bang this week to northern Ohio

Current research: Quicksilver applications during dormancy – pushing the limits

It’s hard to believe temperatures are forecasted in the upper 50’s in Wooster, Ohio for the next seven days. While creeping bentgrass (Agrostis stoloifera L.) remains dormant, silvery-thread moss (Bryum argenteum Hedw.) is going to take full advantage of this warm winter weather. When water is available and temperatures are >40ºF, silvery-thread moss is actively photosynthesizing, producing new shoots, and gaining a foothold in putting greens. Silvery-thread moss’ lack of temperature-related dormancy is concerning because since January 1st we’ve had 27 days of temperatures >40ºF and 12 days of temperatures >50ºF in Wooster. It’s becoming apparent that moss control strategies may need to continue throughout the winter months to prevent a surge in population growth during unseasonably warm weather.

Many superintendents rely on applications of Quicksilver to keep moss populations in check throughout the growing season. Quicksilver’s active ingredient, carfentrazone-ethyl controls weeds by inhibiting an enzyme involved in chlorophyll synthesis, which eventually results in the breakdown of cellular membranes. Oppositely, a healthy creeping bentgrass plant can rapidly metabolize carfentrazone-ethyl into non-herbicidal compounds; however, during stressful conditions (e.g. low and high temperatures) the enzymes involved in this detoxifying process may not have the ability to metabolize all of the herbicide and injury could occur. During these abnormally warm, moist winter days, silvery-thread moss is active and should be injured by an application of Quicksilver, but what about the creeping bentgrass? From a theoretical perspective, chlorophyll production should be nonexistent if creeping bentgrass is dormant; therefore, no pathway would be available for carfentrazone-ethyl to inhibit, and injury to creeping bentgrass would be unlikely. Because the aforementioned statement is entirely theoretical, we decided to conduct field trials throughout the midwest and eastern United States to determine if a winter application of Quicksilver would injure creeping bentgrass.

To test our objective, researchers applied Quicksilver to creeping bentgrass putting greens at 0, 1.6, 3.3, 6.7, and 13.4 fl.oz. product per acre (Note: 13.4 fl.oz. per acre is twice the label rate). Following the application, researchers will collect NDVI measurements and report any negative effects to the creeping bentgrass. Currently, this study is being replicated by researchers at Ohio State, Rutgers University, Kansas State University, University of Nebraska-Lincoln, and the Chicago District Golf Association. We will monitor the putting greens until mid-June and report the results in the months following!

GIS in Orlando

As we get ready to expose our students to the ‘national’ as some in the industry call it we need to let everyone know that ATI will be down there with a booth. The booth will be located beside the Ohio State Universities four year program and we will be looking for as many alumni to call in as possible – there is a lot going on here lately!

Students are traveling for the turfbowl and they will also be manning the booth – expect raffles and plenty of giveaways as well – stop in and reacquaint yourself with the program – we want to talk to you!
