“…The application of culture filtrates containing secondary metabolites produced by the 4 Trichoderma species in agar plates, reduced the growth of Fusarium mycelia. These results coincide with many other works and depend on the species tested (Bolar et al 2000, Reino et al 2008, Li et al 2015, Moosa et al 2016.…”

“…Bal & Altintas (2008) also demonstrated that application of T. harzianum did not increase yield in tomato. On the other hand, integrated management of Fusarium wilt in tomatoes using cow manure and a combination of T. viride and T. harzianum produced the best inhibition and showed lower levels of disease severity in in vivo experiments (Moosa et al 2016). The use of T. spirale as biological control agent is uncommon and few reports on its biological characterization are available in the literature.…”

El uso Trichoderma spp. se ha incrementado en la actualidad para el control de hongos patógenos de plantas. En Venezuela los productos comerciales a base de Trichoderma son formulados casi exclusivamente a partir de esporas de T. Harzianum, pero muchos experimentos han reportado en la literatura un mejor desempeño de otras especies nativas no comerciales en comparación con los productos formulados en el país. En este trabajo, 4 especies nativas de Trichoderma Persoon fueron evaluadas en condiciones de laboratorio y en invernaderos comerciales para el control de la marchitez del Fusarium en una variedad de tomate tipo “cherry” de crecimiento indeterminado. Diferentes experimentos fueron realizados para evaluar el antagonismo, micoparasitismo, endofitismo, efecto de metabolitos secundarios producidos por Trichoderma y el efecto agronómico de esas especies en los invernaderos comerciales. Las especies evaluadas fueron: T. koningiopsis Samuels, Suárez & Evans, T. virens Mill., Giddens & Foster, T. spirale Bissett y T. harzianum Rifai. De todas estas, T. spirale mostró los mejores resultados en todos los experimentos. Trichoderma spirale fue capaz de inhibir el crecimiento de Fusarium hasta el 79% en placas de PDA; mientras que sus metabolitos secundarios redujeron el crecimiento del patógeno en un 64%. Por otro lado, mostró un efecto protector contra Fusarium en condiciones in planta en pruebas de laboratorio, reduciendo la enfermedad en 70%. También demostró un efecto positivo en el crecimiento de la planta, posiblemente la acción edofitica de T. spirale. En condiciones de invernadero T. spirale produjo los mejores resultados luego de 90 días post-transplante con el aumento del tamaño de las plantas, la producción de tomates por racimo junto con la protección de las plantas contra la marchitez del Fusarium. Los resultados obtenidos con la cepa nativa de T. spirale usada en este trabajo demostraron que este organismo posee un gran potencial como agente de control biológico.

“…This finding suggested that the genetic variability of antagonistic isolates played an important role in biocontrol activity. The results of this study were in agreement with a study conducted by Moosa et al (2017) in which the variability of antagonistic activity depends on the isolate genetic potential and its origin. It was demonstrated that seven Trichoderma isolates had an antagonistic activity to suppress the growth of three soil borne pathogens with different levels of inhibition.…”

Abstract. Yusnawan E, Inayati A, Baliadi Y. 2019. Isolation of antagonistic fungi from rhizospheres and its biocontrol activity against different isolates of soil borne fungal pathogens infected legumes. Biodiversitas 20: 2048-2054. Soilborne diseases caused by Rhizoctonia solani and Fusarium sp. are biotic limits for legume production. Biological controls offer environmental friendly control for these pathogens. This study aimed to isolate and screen Trichoderma from different rhizospheres and to obtain effective Trichoderma isolates to suppress in vitro growth of the soil borne pathogens. The antagonistic inhibitory activity was performed by dual culture method. Seven out of forty indigenous Trichoderma isolates collected from East Java, Indonesia effectively suppressed the growth of different fungal isolates, namely Rhizoctonia solani (R.s1), R. solani (R.s2) as well as Fusarium sp. which infected soybean and mung bean. In vitro study showed different suppression of the pathogens on dual culture tests. The seven isolates inhibited the growth of R. solani (R.s1), R.solani (R.s2) and Fusarium sp. ranging from 90.0 to 99.6%, 72.8 to 82.4%, and 67.9 to 90.8%, respectively. Isolate origin and genetic variability of Trichoderma played an important role in the antagonistic activity. The fast-growing of selected Trichoderma showed their abilities for space occupation and nutrition competition, which involved in the antagonistic activity. The mycelial growth of Trichoderma over pathogens showed hyperparasitism mechanism. In addition, coiling of Trichoderma over hyphal pathogens was observed during microscopic observation. The seven Trichoderma isolates, therefore, are promising as biological control agents against the soil borne fungi infected legumes.

Trichoderma species are recognized as biocontrol agents with great potential in inhibiting fungal pathogens that cause significant crop losses. In this study, 15 Trichoderma isolates were collected from various Egyptian locations. Internal transcribed spacer sequencing revealed four different Trichoderma species; Trichoderma harzianum, Trichoderma asperellum, Trichoderma longibrachiatum, and Trichoderma viride. The antagonistic activity of Trichoderma isolates against Fusarium oxysporum f. sp. capsici was evaluated in vitro. The effect of Trichoderma isolates on pepper growth plants in the presence of F. oxysporum was studied in planta. The inhibition of pathogen mycelial growth in vitro ranged between 35.71%and 85.75%. The isolates Ta3 and Tl had the highest antagonistic ability in vitro against F. oxysporum f. sp. capsici. However, Th7 and Th6 of T. harzianum isolates showed the highest values of disease severity reduction under greenhouse conditions. The genetic diversity of the Trichoderma isolates (Ta1, Ta2, Th1, Th2, Th3, Th4, Th5, and Tv) was investigated on the basis of ISSR and SCoT markers. SCoT primers generated a total of 28 bands, out of which 14 (50%) were polymorphic. ISSR primers gave 32 bands, and 11 of these bands (34.37%) were polymorphic.
