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...

The Asian Turfgrass Roadshow 2012 started with a seminar at Sentosa Golf Club in Singapore, host site for the European Tour’s Singapore Open. Dr. John Kaminski, with only a few hours of sleep after his travel from the other side of the world, exactly twelve time zones away, gave two...

Fungicide book, and thinking about summer patch – earlier than usual
It’s been awhile since we’ve plugged this book, so I’ll do it again: It’s a terrific resource for any turfgrass manager. You can find more details about the contents and purchase it at this website: http://www.apsnet.org/apsstore/shopapspress/Pages/43924.aspx Summer patch Summer patch symptoms tend to...

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...

A New Year and Winter Meetings
Happy belated New Year! I know I haven’t had a recent contribution to the blog, but things got pretty busy for the Turf Team at Oklahoma State University this fall and into the new year. We had our 66th Annual Oklahoma Turfgrass Conference and Trade Show in Stillwater in...

large patch
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 patch to be a problem on ...
Like Megan, I’m going to give the new blog format a test drive with this post. I also want to make some comments about what is happening in the South-central U.S. As you can see by the title, it appears that it might actually rain. Check out the beautiful screen shot taken from the Oklahoma Mesonet this morning for the Stillwater area. Simply marvelous! We were hot yesterday and will be again today, but that forecast sure looks like relief to me. With that said, be sure you have a good preventative fungicide down. We are likely going to get...
Hi, I don’t have a lot of news, but I wanted to share these very cool photos that were sent by Darin Pearson at Eagle Bend Golf Course in Lawrence. The course is stripping zoysia into rye, and you can see how the large patch is expressed in the susceptible turf (zoysia) while leaving the rye seemingly untouched. Starting tomorrow I’m off to Tajikistan for about 10 days. I wonder how the turf world will change while I’m gone. It could be cool and rainy, hot and dry, hot and sticky… we’ll see. It’s always interesting to see how quickly...
The major news around here this week has been the weather. No, that’s not a photo of the Mother Ship come to take me home, that’s the back of one of the many storm fronts that passed through this past week. I’m sure you have all heard about the devastating tornado in Joplin. Other communities in the region were also struck. Along with the violent winds, hail, etc, abundant rain has accompanied some of the storms. The University of Arkansas talks about wet conditions in their area. They also shared some images of flooding from some storms a few weeks...
Spring dead spot of bermudagrass After a cold winter throughout much of the Southeast, damage from spring dead spot is particularly severe on bermudagrass. Scenes like this one are all too common when visiting golf courses in North Carolina right now. We’re also seeing an unusually high number of spring dead spot outbreaks on zoysiagrasses across the southeastern US. Samples, photos, and reports of spring dead spot on zoysiagrass fairways, tees, lawns, and landscapes have been rolling in all spring. Spring dead spot of zoysiagrass? Yes, this is not a new thing. Spring dead spot was first documented in zoysiagrass by...
Spring dead spot of bermudagrass As the old joke goes, “In the transition zone, we can grow all of the turfgrasses, we just can’t grow any of them well”. The last year has been an excellent demonstration of this fact. Spring 2010 brought major problems with winter-kill in the warm-season grasses across much of the southeast. Everyone will remember the summer of 2010 as the year when record heat caused widespread failure of creeping bentgrass putting greens. Large patch of bermudagrass The spring of 2011 hasn’t been much kinder. Spring dead spot is particularly severe on bermudagrass this spring, and...
