Popis: The observed survival of Pinus patula seedlings and cuttings has, on many occasions, been inadequate in nurseries and after field planting in South Africa. There have however, been several reports that survival can be improved if a fungicide is applied at planting, indicating that mortality is partially related to pathogenic activity. This paper summarises the results from two trials established to investigate the effects of the fungicide, Benlate (a.i. Benomyl), and biological control agents, Trichoderma harzianum and Bacillus subtilis, on P. patula survival and growth. During the nursery raising period, the pathogen Fusarium circinatum was isolated from all dying material. Field results from the trials indicate that initial (
