Abstract: Between 1990 and 1991, compost production units were assessed for the presence of Trichoderma species through the collection of air, swab and compost samples. The Trichoderma species isolated were Trichoderma harzianum, T. viride, T. longibrachiatum, T. koningii, of which T. Harzianum was the most commonly isolated species. From the Tharzianum isolates collected, 3 distinct types were recorded, varying in both radial growth and sporulation rate. These types were finally designated as Thl, Th2 and Th3, confirming previous work by Seaby (1987). Th2 was found to be the cause of 'green mould' in mushroom compost, where Thl and Th3 did not cause a compost problem. The survey of compost production units recorded Thl as the predominant type isolated from the compost yard, making up 84% of T.harzianum isolates collected; Th2 -15% and Th3 - 1%.
