The effect of HWT on the cultures of anthracnose and stem-end rot-causing pathogensthe sources of anthracnose (C. gloeosporioides) and stem end rot-causing (L. theobromae) pathogens. and on the overall quality of fruit was examined. At this exposure however, the propagules of Colletotrichum gloeosporioides and Lasiodiplodia theobromae were not totally controlled. HWT was unstable in controlling C. gloeosporioides and L. theobromae as demonstrated by high standard deviation of radial growth. HWT manner of control is fungistatic rather than fungicidal as pathogens developed after treatment. Fungistatic activity of HWT was perhaps inadequate to protect the fruit from decay due to absence of residual action.
