| Popis: | The objectives of this study are: (1) to inventory Trichoderma spp. in North Minahasa District, South Minahasa District, and Tomohon City-Minahasa District, (2) inventory of Trichoderma spp. in the rhizosphere of cultivated and fallow gardens, and (3) calculate the population density of Trichoderma spp. all soil samples. The scope of this study is the biological control of plant pathogens, induce plant resistance, and biological fertilizer production. Trichoderma isolation spp. has been carried out by dilution method and cultured on PDA + antibiotics. Population density of Trichoderma spp. calculated using the plate calculation method. Identification of this species function based on the color and patterns of sporulation in the colony; hyphae and clamydospores; conidiophores; and phialides and phialospores. Trichoderma species found in North Minahasa District were T. harzianum, T. koningii, and T. viride; in South Minahasa District, T. koningii and T. viride; and in Tomohon City-Minahasa District, T. koningii and T. viride. In fallow gardens were T. harzianum, T. koningii, and T. viride, and in cultivated gardens were T. koningii and T. viride. Population densities of Trichoderma sp. in South Minahasa District, North Minahasa District, and Tomohon City-Minahasa District, respectively 1,363.64, 466.67, and 26.67 CFU / g soil. |
