Abstract/Contents:"One of the projects we have under way is carrying on various studies of nitrogen, phosphorus and potash on three types of bent under putting green conditions. We are using Arlington, Congressional and Washington. We have Washington in our trials because in Michigan 90% of our greens are Washington and I don't think that the clubs are going to be changing them too fast. We have some Arlington and Congressional, too. For some reason or other on some of our plantings of Congressional and Arlington in Michigan they look very good until they are put under playing conditions and then they begin to thin out. In Michigan instead of being nice vigorous growing grass like they are supposed to be. We have continuation of the project that Bill Daniel worked on for his doctor's thesis - the irrigation and height of cut studies. We have enlarged it to include Merion bluegrass, Astoria and Colonial bentgrasses along with Kentucky bluegrass and creeping red fescue. So far we have found that we can maintain better turf with much less water than we have been using on a lot of our golf courses. We have one set of plots that we have started this year on which we are going to run compaction studies and then aeration or cultivation treatments using the different types of machines. We have a series of plots for trying out different types of bents and other grasses under different conditions, for putting greens and fairways and lawns. It includes not only trying out the grasses, but trying out fertilizer and cultural treatments along with them to see what types of conditions we need to grow them. A year ago we planted U-3 and Z-52 in rows. They came through the snow looking very nice. Then we had some alternate freezing and thawing weather and in the areas where they had stolons with roots in the ground, the stolons all raised up and died. In the parts that were compacted and knit firmly together they came through and the U-3 this summer has looked very good and the Zoysia has done very well also. It hasn't been quite the answer to being weed free turf because the season has been fairly cool and it hasn't grown as fast as it does in some places and some of our cool season weeds have come in. We can take care of them, but they are there. I want to try some different treatments in carrying them over the winter to see if we have to cut them or if bedding them will be useful. We have some places where we could use them if we could carry them through and make work. We have some strains of bermuda that have been growing on the campus for a long time. The only thing about them is that they shift around. One year they are in one place and the next year they are in another place. In addition to the work that I am doing, Dr. Grigsby in the Botany Department is carrying on the chemical weed control work including the cooperative crabgrass experiments. Dr. Vaughan and his associates in the Botany Department are carrying on studies of disease control. Most of their work last year and this year has been aimed at the control of helminthosporium on bentgrass greens. They have found two species in the greens and as far as we are concerned, I think the helminthosporium damage to the greens is probably one of the number one problems that we have. We have tried Actidione and it looks very good. The only thing wrong is that the manufacturing company hasn't offered it for sale yet."
