Abstract:

 Objective: The aim is to determine the biological control potential of rhizobacteria isolated from the rhizosphere of tomato plants against soil-borne fungi that cause disease in tomato plants. Materials and Methods: The biocontrol potentials of 10 different rhizobacteria strains against 3 different fungal pathogens Fusarium oxysporum HMK2-6, Rhizoctonia solani HB-66, Verticillium dahliae YY-14, and their plant growth-promoting characteristics were determined in vitro. In addition, the effects of two selected strains among these strains against R. solani were determined in vivo. Results: It has been determined that Pseudomonas chlororaphis strain T142 and Bacillus subtilis strain T139 decreased the disease severity of R. solani at rates of 19.9 and 11.9, respectively. In addition, Bacillus subtilis strain T139 increased the root growth of tomato plants compared to negative control. Conclusion: Rhizobacteria strains in this study showed promising results for the biological control of R. solani in tomato plants.

 Amaç: Domates bitkisinde hastalığa neden olan toprak kökenli funguslara karşı, domates bitkilerinin rizosferinden izole edilen rizobakterilerin biyolojik mücadele potansiyellerinin belirlenmesidir. Materyal ve Yöntem: 10 farklı rizobakteri izolatının bitki gelişimini teşvik etme ve 3 farklı fungal patojene Fusarium oxysporum HMK2-6, Rhizoctonia solani HB-66, Verticillium dahliae YY-14 karşı biyokontrol potansiyelleri in vitro koşullarda belirlenmiştir. Ayrıca, aralarından seçilen iki rizobakteri izolatının R. solaniye karşı etkisi in vivo koşullarda belirlenmiştir. Araştırma Bulguları: Pseudomonas chlororaphis T142 strainin 19.9 ve Bacillus subtilis T139 straininin 11.9 oranında biyokontrol etki göstererek R. solaninin hastalık şiddetini azalttığı tespit edilmiştir. Ayrıca Bacillus subtilis T139 izolatı, domates bitkilerinin kök gelişimini kontrole göre artırmıştır. Sonuç: Çalışmada kullanılan rizobakteri izolatları domateste R. solaninin biyolojik mücadelesi için ümit vadedici sonuçlar ortaya koymuştur.
