Abstract

This study was done to determine the species of biological agents Streptomyces sp. from Pare-Kediri tomato land and Gliocladium sp. from Food and Horticulture Crops Protection in Pandaan, and to know their antagonistic effects on F. oxysporum f.sp. lycopersici soil borne pathogens from Wajak village, East Java, Indonesia. Treatments were laid out in CRD with 4 replications. Biological agents were identified through its morphological characteristics and DNA sequensing. Streptomyces sp. was identified as Streptomyces griseorubens and Gliocladium sp. as Gliocladium virens. The results showed that S. Griseurubens, G. virens and T. harzianum were hiperparasites of F. Oxysporum. They can potentially compete with F. oxysporum for food and space in rhizosphere through the formation of pheripheral roots. The third mixture of these biological agents also produced antibiosis in the rhizosphere that could inhibit F. oxysporum f.sp. lycopersici growth.
