Recently, the phenomenon of localized dry spots (LDS) occurring on bentgrass sand greens of golf courses has caused serious problems in Japan. In this study, we surveyed various districts of Japan and occurrences of LDS in certain golf courses. Using a question-nair, followed by several experiments and observations, we attempted to find the possible cause (s) of LDS on bentgrass golf greens. Regardless of the season, spot sites occurred in areas with low soil moisture and high soil temperature. Treatment with a wetting agent was effective in diminishing dry spot areas.<BR>By examining the soil temperature and soil moisture, it might be possible to predict potential LDS sites before they occur.<BR>Preliminary treatment of sites that have high soil temperature and low soil moisture with wetting agents might be an effective way to avoid the occurrence of LDS.
