“…Compared to control treatment, bioformulation-treated bananas contained lower chlorophyll content. Similar to other reports, BCA-treated plants contained lower or showed no significant difference in chlorophyll content than control treatment ( Patel & Saraf 2017a ; 2017b ). The overall improved plant growth in bioformulation-treated Berangan could have contributed to lower chlorophyll content as energy was diverted for vegetative growth under stress conditions ( Teh et al 2015 ).…”

Fusarium wilt of banana cannot be effectively controlled by current control strategies. The most virulent form that caused major losses in the banana production is Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc-TR4). Biocontrol of Foc-TR4 using microbial antagonists offers a sustainable and eco-friendly alternative. A consortium of biocontrol agents (BCAs), Pseudomonas aeruginosa DRB1 and Trichoderma harzianum CBF2 was formulated into pesta granules, talc powder, alginate beads and liquid bioformulations. Previous study indicated bioformulations containing both BCAs successfully reduced the disease severity of Foc-TR4. To date, the biocontrol mechanism and plant growth promoting (PGP) traits of a consortium of BCAs on infected bananas have not been explored. Therefore, the study was undertaken to investigate the effect of a consortium of DRB1 and CBF2 in the growth and biochemical changes of Foc-TR4 infected bananas. Results indicated pesta granules formulation produced bananas with higher biomass (fresh weight – 388.67 g), taller plants (80.95 cm) and larger leaves (length – 39.40 cm, width – 17.70 cm) than other bioformulations. Applying bioformulations generally produced plants with higher chlorophyll (392.59 μg/g FW–699.88 μg/g FW) and carotenoid contents (81.30 μg/g FW–120.01 μg/g FW) compared to pathogen treatment (chlorophyll – 325.96 μg/g FW, carotenoid – 71.98 μg/g FW) which indicated improved vegetative growth. Bioformulation-treated plants showed higher phenolic (49.58–93.85 μg/g FW) and proline contents (54.63 μg/g FW–89.61 μg/g FW) than Foc-TR4 treatment (phenolic – 46.45 μg/g FW, proline – 28.65 μg/g FW). The malondialdehylde (MDA) content was lower in bioformulation treatments (0.49 Nm/g FW–1.19 Nm/g FW) than Foc-TR4 treatment (3.66 Nm/g FW). The biochemical changes revealed that applying bioformulations has induced host defense response by increasing phenolic and proline contents which reduced root damage caused by Foc-TR4 resulting in lower MDA content. In conclusion, applying bioformulations containing microbial consortium is a promising method to improve growth and induce significant biochemical changes in bananas leading to the suppression of Foc-TR4.

“…Martínez et al (2008), evaluated 59 Trichoderma isolates and reported a strong competition for the substrate, especially competing for nitrogen, carbohydrates and macronutrients. The beneficial effect of Trichoderma on the protection of tomato plants in vivo under laboratory conditions, demonstrate that T. spirale strain used in the experiments, protected the plants again the pathogen and also improve their agronomic variables, possibly because improving water and nutrient intake by the plants (Santander et al 2003, Patel & Saraf 2017. The increased dry weight tomato plant stems and roots by different Trichoderma species has been reported previously (i.e.…”

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.

The aim of this study was to evaluate the influence of cultivar and biostimulants on the health status of potato tubers after harvest and after 5 months of storage. The fungal pathogens isolated from potato tuber were cultured on PDA. The biostimulants limited the symptoms of dry rot in cv. Satina after harvest, in stored cv. Irga (Bio-Algeen S-90) and cv. Blaue St. Galler (Kelpak SL). The symptoms of common scab were reduced in stored potatoes cv. Satina in the Asahi SL treatment and the symptoms of late blight in stored potatoes cv. Satina in the Kelpak SL and Trifender WP treatment and in cv. Valfi in the Bio-Algeen S-90 and Kelpak SL treatment. Asahi SL and Kelpak SL decreased the severity of black scurf in stored potatoes cv. Irga. Biostimulants decreased the occurrence frequency of the causative agents of dry rot and black scurf after harvest. Total chlorogenic acid, which is predominant in potato tubers, was present in higher concentrations in the skin than in the flesh. Potato tubers had the highest content of 5-caffeoylquinic acid, followed by neochlorogenic acid (3-caffeoylquinic acid) and cryptochlorogenic acid (4-caffeoylquinic acid). Higher concentrations of chlorogenic acid were found in potato cultivars with blue-purple-and red-colored flesh than in those with yellow-and cream-colored flesh, and in response to the application of the Asahi SL biostimulant and Trifender WP.
