Abstract
A study of fungi responsible for root rot of Pinus patula seedlings in a forest nursery yielded Fusarium subglutinans f. sp. pini and F. oxy sporum. F. s. pini was isolated most frequently from diseases seedling s and proved to be the most virulent fungus in pathogenicity tests con ducted on germinated seed and 2-mo-old seedlings. Inoculation of 3-yr- old trees with F. s. pini yielded symptoms reminiscent of pitch canker . This is the first report of F. s. pini causing root discase of pine seedling and is also the first record of the fungus in the Southern He misphere.
