20 ml of a chlamydospore suspension were injected into the soil 7 cm 

 from the plant.

z + = conidia of each of five isolates (three isolates of Trichoderma 

 harzianum , one isolate of Penicillium restrictum , and one isolate of 

 Aspergillus ochraceus) were added to the crown area of the transplant 

 at 5 X 10-' conidia of each isolate per pot.
