Because of the increased interest in endophyte-infected grasses, an efficient detection method was deemed necessary. To facilitate screening a large number of individual seeds and plants, a rapid, safe staining procedure was developed using rose bengal. Previous methods were time-consuming and often required careful boiling of the plant tissues. The rose bengal staining procedure is simple and effective and gave excellent visual results. Minimal staining times of 3060 sec gave good fungal differentiation even in thick tissues, and no additional fixing was necessary. Seeds and dried tissue also were stained effectively.
