Abstract :Nowadays, pestisides and organic compounds are being widely used to inhibit pathogen microorganisms. Degradation of these compounds are very difficult and accumulation and concentration of them in food chains leading to toxicity in animals at higher tropic level. As a result, biological control has become increasingly important in recent years. It is showed that Tricho-derma spp. could be used as a biocontrol agent. In this study, spore production and mycelial growth of Trichoderma harzi-anum isolates were studied in vitro. The lowest colony diameter was obtained from isolate T7 in urea. It was followed by T14. Differences in dry weight of mycelial growth of T. harzianum were observed between the isolates and addition of fertilizers to the media increased numbers of spores. Addition of fertilizers to the media increased number of spore. There was maximum spore production in urea, ammonium sulphate and urea + triple super phosphate.
