TURFCOMMS V. 7, L 8 Mar. 28, '94 PURPOSE: To pass on what we learn willingly and happily to others in the profession so as to BOY HAVE I BEEN CATCHING HECK LATELY: See letter below from TGIF and then there was Gary Schinderle, Golf Enviro Systems, Inc. called telling me that he had been telling me about Humate (see last issue) for three years and I better put his phone number in the next issue. Gary's Company is national Distributor for S.L.S. Humates, call him at 1(800) 225-1311 {if in Colorado area} and tell him where you saw his # and that he owes me a free sample. "Dear Dr. Hawes, 28 January 1994 It was with major concern that I noted your editorial in the December 27, 1993 issue of Turfcomms. concerning several issues relating to TGIF and TIC. I hope to be able to address the points you raise, in some cases providing explantaions, in others, corrections. 1. We do have a major backlog on processing online activation applications. This is in part due to software limitations and complexities, staff shortages, competing fulfillment pressures, as well as a rapid increase in new subscribers, like yourself, wishing to take advantage of the online option. This is regrettable and not in keeping with our efforts and intentions to provide rapid turnaround. We are attempting to eliminate this backlog, and fully intend to do so. My apologies for this unfortunate delay. 2. When an individual "subscribes" to the Center, it can be for many reasons, one of which is to gain online access to TGIF and the other databases. Only about 50% if (sic) TIC subscribers, however, request the use of this no-initial-extra-cost option. That may have been your primary motivation for becoming involved, but it is certainly not the only reason to become involved by subscribing. 3. Regarding USGA support for the TIC project: USGA has continued to support the project since the completion of grant funds from the USGA Turfgrass Research Program ended in February of 1993. USGA Green Section personnel, including National Director Jim Snow, sit on the Center's Advisory Council, which now provides the primary external visibility, fund-raising, and feedback focal point for moving the project forward. The USGA Green Section was the first Golf Corporate subscriber under the revised subscription structure which went into place in January of 1993. I would hardly categorize this as no support, whcih the final line of the paragraph certainly implies. TURFCOMMS is published at unpredictable intervals by the editor and publisher: improve turf conditions around the country. Douglas T.

Send checks to Doug Hawes at the above address 4. Regarding Michigan Stated level of commitment to the project, and, more importantly, the concept of collecting, preserving, and providing access to the printed record of turf science and management; the record speaks clearly for itself. It began more than 20 years before I arrived at MSU, and more that (sic) 20 years before the first USGA grant monies were directed towards beginning the process of building TGIF. TGIF is, after all, a database. It is based on a Collection, the O.J. Noer Memorial Turfgrass Collection, growing throught the 60's and thereafter, beginning with Dr. James Beard's recognition of the need to have SOMEWHERE where the "Ibrary" intersest of the discipline and profession were seriously and systematically worked on. The O.J. Noer Foundation has maintained a 
long ter interest and financial stake in the development of the Collection. In addition, many, many, individuals over a very long period of time have made this project a reality, even as most individual's involvement has come and gone. It began before your M.S. at Cornell (R-10301 in TGIF), well before my arrival in 1985, and it will continue when both of us are no longer active in the turf arena." "We all owe a debt to those who labored long and hard before the reality could catch up with theory on this one; many of those individuals were at MSU. 5. The future success and continued construction of TGIF is directly dependent on outside support from Foundations, 
Associations, Corporations, and Individuals, such as yourself, and a willingness to give as well as take from the shared resource which TGIF represents Š the literature. I hope these comments have clarified a few points; again, my apologies for the delay on online activation. You will get time credit for the time lag. As we discussed on the phone some time ago, please let us know if we can supply any searches directly to you until you are active online, at no charge. Incidently, I note that we do not have a copy of either your Thesis or Dissertation in the Noer Collection; copies of both would strengthen both the Collection and TGIF. Any such help is always appreciated. Sincerely, Peter O. Cookingham, Project Manager." Peter, Thesis is in the mail. Doug. H. REBOUND, ground rubber tires and compost, is a soil modification well worth looking at for those walkways on to greens and other heavily trafficked areas. After seeing their booth at The GCSAA Show I called Tommy Anderson of the Broadmoor and asked him about his experience with this product. He said that so far it has been pretty positive but, too early to make any decision yet (2/16/94). This is NOT an inexpensive solution to an old problem but the soil physics sounds good and ground rubber tires don't decompose very fast. Again it is worth a try. Call 1-800-795-8473 for more 
information, in Colorado 303-322-7887. Or read the article in Grounds Maintenance, March, '94. FOR A TURF ADVISORY VISIT CALL (214) 867-0176 and ask for the Doc. Dr. Virginia Lehman Marries Old Prof. or would you prefer Well know Turf Breeder Marries Former Student When I heard the news just prior to publication several headings came to mind, so I thought I'd poke a little fun but didn't dare print some of those headings. I was told 3/26/94 that Drs. Milt Engelke and Virginia Lehman were married not too long ago. I wish them the best of luck. I never thought Dr. Engelke would ever marry again. A decade ago he wouldn't even go to somebody elses wedding. I was with him on the San Antonio Riverwalk about ten years ago and when he saw a wedding being performed up ahead, he told me I could keep going that way but he was turning around and heading elsewhere. Which he did real fast. Well he married a winner this time, the second time for both by the way. Virginia is one great lady and with their combined energies and the many other attributes and interests they have in common it should be a dynamic and productive marriage. TEXAS TURF CONFERENCE - Dr. Monica Elliott: I've been saving two talks by Dr. Elliott because I was spending a lot of time adding to a fungicide list she handed out that I wanted to pass on to my readers. Dr. Monica Elliott, plant pathologist from the Univ. of Florida, gave a talk entitled "Managing Patch Diseases in Turf'. She prefers the name Root Rot Patch Diseases and includes Summer Patch, Necrotic Ring Spot, SDS, Bermudagrass Decline, Take All Root Rot and Take All Patch in this group. The things these diseases all have in common according to Dr. Elliott are: dark pigmented fungi which colonize roots, penetrating the root vascular system causing a root rot and collapse or plugging of the xylem and phloem tissue. Also she notes, by the time you see the symptoms it is too late to control these disease that year. She went on to report that nutrition does appear to affect these diseases in that ammonium nitrogen reduces the effects of the disease; while nitrates and lime increase the severity. Urea based nitrogen is intermediate. Acidifying the soil reduces the severity and so does high soil potassium levels. The effects of micronutrients is still questionable. For control only use systemic fungicides and realize that they, for the most part, only move up in 
the plant therefore they must be drenched into the soil. Bayleton, Rubigan, Fungo, 1991 and Banner are effective if applied preventative. She did make it clear that one should not use Banner 
when the temperatures go over 93°F. Dr. Monica Elliott gave a second talk titled "How to mix Fungicides". I thought this was excellent but trying to take notes from her lecture and slides proved to be almost impossible there was just too much good information. She did give a handout which I'm including. Here is the few notes I was able to get. DO NOT MIX FUNGICIDES WITH HERBICIDES. Do not mix with surfactants unless the label specifies. She praised the Subdue label as being one of the best to show what it is compatible with. She noted that Subdue should always be watered in with 1/4 to 1/2 inch of water. Aleitte should not be mixed with foliar fertilizers, metal ions, surfactants, or flowable Daconil 2787. The latter I, the editor, would never use on bentgrass/ Poa annua greens in the summer time. That the Pennwalt label for Maneb carries a 24 hour waiting period. That Algaen-X (Consan 20) should not be mixed with anything and be sure to use lots of water with the high label rate. For Banner the addition of surfactants may result in phytotoxicity and do not mix with 1991 or a fertilizer solution. She gave out a handout which I am including as a separate sheet. I am including it because it is so critical to not only switch fungicides periodicly but when you make a switch it needs to be to a product in another chemical class. This handout makes it easier to identify the chemical classes. I have added the common name for the products in the O.M. Scott's line as well as Lesco and other information I could find at the GCSAA Show including the new fungicide ProStar and a new biological fungicide. I suggest you add the common names of the chemicals you commonly use and any you consider using. Turfgrass Fungicides Grouped by Trade and Common Names - List One Grouped by Class - List Two These two lists of fungicides were stimulated in part by a talk given by Dr. Monica L. Elliott, University of Florida - IF AS, Fort Lauderdale Research and Education Center atTexas Turf Conference, Dec. 1994. The arrangement of fungicides by class is her list. I wish to thank her for proofing this paper and adding many comments. Additions which have been made by me, Dr. 
Douglas T. Hawes, are shown in Hobo-WP, any fungicide left out or any mistakes made are my fault. The grouping by trade and common names followed by class was an idea of mine that I thought would help make her list more useful. Products are grouped according to chemical class for several reasons. As disease control becomes more sophisticated disease control experts such as Dr. Elliot tell us that we should never mix fungicides belonging to the same chemical class. Secondly, when we want to alternate fungicides to avoid development of resistant strains of pathogens it is wise to alternate to another class of fungicide. When we want to obtain a broad spectrum of preventative control it is also wise to combine fungicides of different classes. The combination products on the market such as Broadway, Duosan and Fungicide VIII do this for us. To assist you in making fungicide decisions I have made an alphabetized list of fungicides by common and trade name. Then for each of these we have given you the class. These two 
groupings allow several approaches to making fungicides selections. You may go down the list of common and trade names until you find the fungicides you want to use and quickly determine whether they are in different classes or you can go to the class your principle fungicide is in and find what other fungicides are in that class so that you will know what you shouldn't be using with it.
