Abstract/Contents: | "1. A series of studies on turf cultivation include different intensities, season and sites for cultivation treatment. The Aerifier is principal cultivating tool in use. Some of the preliminary results are as follows: 1. Use of the Aerifier at different seasons and intensities has not created any weed problem. 2. Preliminary results from turf cultivation suggest that it may have no measurable value on areas that do not have a thatch or sod compaction problem. This past year we have established some cultivation treatments on areas having thatch and soil compaction; however, we have no results to report. II. The effect of fertilization practices on Poa annua is receiving considerable attention. It is hoped that some of the basic fundamentals on rates and time of application can be determined. The preliminary results obtained to date show that fertilizer practices have a profound effect on the comparative amounts of Poa annua and bentgrass. Additional study is being made to determine the reasons. III. Tests are being conducted on new and standard fungicides. Large brownpatch and copperspot are the diseases most frequently encountered on the tests. The inorganic mercury type has been the most effective on both diseases. Among the new materials, Orthocide 406 has shown real promise for large brownpatch control. It has given considerably better control than Tersan and it has ranked second to the inorganic mercuries only. It has given no discoloration to date which gives it one advantage over mercuries. IV. Crabgrass Control 1. Chemical crabgrass control has received considerable attention. It is not expected that the use of chemicals serve as a ready cure for crabgrass. Several phenyl mercury compounds have been found very effective. We have tested potassium cyanate each year since 1948 and we have found it to give good results on the bluegrass type of turf. We have tested a number of experimental chemicals since 1948. Of these several boronium fluoride compounds, such as S-1998 and S-1840 have been most promising. To date neither of these have been sold commercially. This past season, we have been doing some work on gallonage and dry application of potassium cyanate. As to the future, we believe that the large number of chemicals being developed for herbicidal use may reveal other chemicals of value for crabgrass control. 2. Control of crabgrass by mechanical treatment. In 1951 a comb mounted in front of the mower reel and an arrangement of vertical knives behind the mower were used on crabgrass infested turf. The results obtained indicate that mechanical treatment of crabgrass may be a very useful procedure. The equipment was supplied by the West Point Lawn Products and the financial support was supplied by the U. S. Golf Association. V. Studies conducted with new grasses. The following studies are in progress. 1. A performance test of Highland bents, Astoria bents and Seaside bent. 2. Trial plantings U-3 bermuda and Zoysia matrella. 3. A strain test of 15 bentgrasses at ¼ inch cut 4. A test of Merion and other Kentucky bluegrasses. Merion bluegrass appears to be one of the most noteworthy improvements. During the past three years it has shown greater tolerance of the 3/4 inch cut and more resistance to leafspot disease than the other Kentucky bluegrasses used. It appears to make a denser turf than the other Kentucky bluegrasses; however, its density is not nearly as great as the bentgrasses. 5. A study has been started to determine the possibility of growing a well-balanced combination turf of B-27 bluegrass and the Z-52 strain of Zoysia japonica. Different management practices will be used to determine their influence on the balance. The Green Section of the USGA has cooperated with us on this study by supplying planting materials." |
