Awesome graphs and cool season grasses!
This trip included one of the best discussion and presentations about Dr. Woods' climate maps and also put me back in touch with cool season turfgrasses. A major issue I saw in Beijing was the desire to start using Kentucky bluegrass throughout the fairways. ...

Hong Kong Clouds and Beijing Botanizing
The seminar was at Clearwater Bay, a course with manilagrass tees, fairways, and roughs. We saw a little bit of dollar spot and heard from superintendent Darry Koster about his preventative fungicide program for large patch (caused by Rhizoctonia solani). It gets just cold enough at Hong Kong for large...

Two-Wheeled Vehicles and Zoysia Putting Greens
We headed to Twin Doves Golf Club where I had my opportunity to see a wall-to-wall Seashore paspalum (Platinum TE variety) golf course. While the course looked great from a distance, it was clear that the grass selection presented its own challenges. While Micah can talk more about this from...

Saigon, San Miguel, and Shade
Except for the superb mountain course at Dalat, with a lot of kikuyugrass (Pennisetum clandestinum) on the fairways and creeping bentgrass (Agrostis stolonifera) greens, all courses at Vietnam have been planted to seashore paspalum or bermudagrass. This is a mistake....

Singapore and Thailand from my perspective
Our first stop during the 2012 Asian Turfgrass Roadshow took us to Singapore. For me, it was about 22 hours in the air (through Tokyo) and a 12:30AM arrival on Monday night/Tuesday morning. Knowing that I wasn't going to be able to sleep right off the flight, I had recent...

Frost impacts new growth in lawns
The unprecedented warm weather in March led to all sorts of plant anomalies, including early flowering in trees and shrubs, germination of annual grasses, and spring green-up of cool-season turf. Although perennial cool-season grasses are well equipped to withstand sudden and extreme temperature drops, new, succulent leaf tissues are susceptible...

Early early early
The temps have been warmer than normal, in some cases WAY warmer. Here in Manhattan it was 89 on April 1. Even the warm-season grasses are growing like mad. Along with the early plant growth, plant diseases are...

Some Much-Needed Rain and Some Unwanted Diseases
In Oklahoma and the Southern Plains, we received some much-needed rain to help offset the drought that has persisted over the last year or so. Some areas of Oklahoma received as much as six inches of rain over the last 10 days. Many have welcomed this, but it...

An Excellent Question Without a Good Answer
What's that question? It is the one posed most frequently by delegates to this week's Sustainable Turfgrass Management in Asia 2012 conference: How can we control bermudagrass in seashore paspalum? The conference saw 210 delegates from 20 countries assemble at Thailand's popular beach resort of Pattaya to discuss turfgrass management...

dollar spot

We saw a little bit of dollar spot and heard from superintendent Darry Koster about his preventative fungicide program for large patch (caused by Rhizoctonia solani).

It’s been a busy week for golf course superintendents in the region as diseases are in high gear and the heat and temperature stress are causing many golf course putting greens to decline. We are hearing a lot of reports of yellowing and discoloration to bentgrass putting greens, possible nematode issues, and the typical diseases that we would expect to see at this time of the year. Rain storms that swept through much of the mid-Atlantic provided some much needed relief from the drought we were in, but in many cases the rain fell too fast and basically moved via...
HOT HOT HOT We’ve been cooking over the past week. We are not as bad as Oklahoma. Just reading Damon’s post made me break into a sweat, both with the thought of those high temperatures AND the thought of the number of samples he’s dealing with. It hasn’t been quite that extreme just a bit north, where I am located. But, this current week has been nasty, with more 100+ on the way. Localized dry spot: This photo was sent in with a subject line that said “Help!!!” While I am not a fan of diagnosing based only by photo,...
We have seen relatively few disease issues in the TDL the past month or so. Throughout Upper Midwest temperatures have been warm, but we have also been quite dry. However the forecast for next week is very different. Highs for next week will been in the low to mid-ninties, more importantly night time temperatures will exceed 72 for most of next week. I included a 7-day forecast from NBC 15 here in Madison, but areas west and south of us will likely experience even hotter temperatures. I know that doesn’t compare with the excruciating heat experienced by those in the...
As I mentioned the last time I posted, I promised to summarize some information that was presented at our Turfgrass Pest Management Field day held on June 15th in subsequent posts.So here goes… One of the fungicide trials that we toured during field day included several different fungicide formulations for control of dollar spot and brown patch on creeping bentgrass putting greens.In this particular trial we applied the newer fungicide Civitas + Harmonizer alongside other conventional fungicide products.As you may remember in previous posts here and here by Dr. Tredway, Civitas performed well for control of dollar spot and did...
Hello, I am back in the US after an agriculture development trip to Tajikistan. If any of you are curious about that, you can check out this website where I have some notes and photos. The photo above is me with the Tajikistan-Afghanistan border mountains in the background.. . https://picasaweb.google.com/mmkennelly/TajikistanVisit2011?authkey=Gv1sRgCMvxxJn_moCCKg . .Anyway, back here on the home front dollar spot is active in putting greens and fairways. Though I have not seen it yet with my own eyes, I have had a few reports of brown patch activity as well. In addition, with some of the recent heat and wind...
I’m posting this from Australia where the winter is just beginning. At the Redlands Research Station near Brisbane today I saw plenty of dollar spot on seashore paspalum. Pictured is a plot of Sea Isle Supreme. These are the typical symptoms of dollar spot that occur when the growth of seashore paspalum is slow. I also saw some interesting mite damage yesterday on bermudagrass (or green couch as it is called here). From a distance the area pictured below looked as if it were suffering from drought stress, but upon closer inspection these severely stunted shoots, so typical of mite...
