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 show up when heat and drought fire up in late June/July/Aug, but the infection occurs in mid/late spring.  The fungus is soilborne and attacks roots.    When the daily max soil temperatures at 2-3 inches deep are consistently (3 days in a row) above 65, that’s a good time to make...

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 did cause...

Update on Some Nematode Control Options for Creeping Bentgrass Putting Greens
In Oklahoma, there are not many options for nematode control in creeping bentgrass putting greens. With the loss of Nemacur, superintendents are left with Nortica (Bayer Environmental Science), Econem (Syngenta Lawn and Garden), and Multiguard Protect EC (Agriguard Company). Curfew (Dow AgroSciences) is a commonly used product for some golf courses in the southeastern U.S. but is not currently ...

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 Mid-November.  Mr. Bob Randquist, CGCS, Boca Rio Golf Club gave the keynote address.  The next two days were filled with educational programming from not only the turf team at OSU, but also several guest lecturers.  Dr. Xi Xiong, Assistant Professor at the University of Missouri gave a very informative presentation...

Looking back at 2011 and ahead to 2012
Hello, Happy Holidays! I’m sure many of us are ready to say goodbye to 2011 and welcome 2012. Before I head back to my homeland of Wisconsin (Go Packers!) tomorrow for Christmas I thought I’d write just a few summary notes from 2011. First, let me...

Spring dead spot and large patch on my mind
We have been busily working on getting our fall spring dead spot and large patch preventative fungicide trials deployed here in Stillwater. In Oklahoma we like to initiate fall, preventative fungicide applications prior to the soil temperature falling back down to ...

Is this what the future will look like without Rubigan?
What will we do when Rubigan is Rubi-gone?
The Gowan Company announced yesterday that it will cease Rubigan sales on December 31, 2012. Gowan has already removed fenarimol from most other markets and is reserving the remaining active ingredient for turf and certain fruits where its usage is...

Rain in Oklahoma? You Don’t say…
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...

A quick test from Megan
Hello out there, I’m mainly just checking out the new format and making sure I can log in and post.  Thanks again to John for doing all the behind-the-scenes management. Last time I posted I was feeling pretty grumpy because it was 108 degrees on Sept 1.  But, things have improved since then.  Except for a mild spike into the 90′s yesterday it’s been lovely, with nighttime lows dipping almost to 40 a few times.  We got new windows this summer at our house, and now we actually get to enjoy having them open.  Woohoo! For the photos and figures,...
