Popis: | Manure pellets produced from processed swine faeces can be used as carrier material for the biocontrol fungus Trichoderma harzianum. The antagonist can grow and sporulate on the processed manure powder as the sole source of carbon and nutrients. The incorporation of conidia in pellets of the processed manure was shown to be feasible on a laboratory scale. Survival of the fungus in the pellets during storage was satisfactory. The population dynamics of T. harzianum were studied using a benomyl-resistance marker after introduction of conidia into soil. The antagonist could colonize and spread through a number of non-sterile soils and was able to establish a stable population over a period exceeding 125 days. Under sterile conditions, the propagation of T. harzianum in soil was much greater than under non-sterile conditions. The incorporation of antagonist conidia in pellets was found to be essential for the successful colonization of non-sterile soil. In growth chamber experiments, application of T. harzian... |
