“…Their results indicated that Trichoderma strains reduce the mycelial growth of Foa isolates tested, with inhibition rates of 63% and 65% respectively. Due to their rapid development and their production of bioactive substances, several Trichoderma species limited the growth of Fusarium species and considered as a powerful microbial antagonists and can be used as a bioprotector or as a plant biostimulant (Sghir et al, 2016;Benouzza et al, 2020;Haouhach et al, 2020;Bustamante et al, 2021;Pani et al, 2021;Hammad et al, 2021). In the same context, the efficacy in vitro of the inhibitory activity of T. harzianum against F. oxysporum were assessed by Hibar et al (2005) who recorded inhibition rates greater than 65%, after a direct confrontation on the PDA medium.…”

“…e activation of Trichoderma strains was carried out in plates containing Papa Dextrose Agar (PDA), for a period of 15 days at a temperature of 25 °C with 12-hour photoperiods (fluorescent white light/darkness) [18]. Subsequently, 5 discs of 0.5 mm in diameter were removed from the Petri dish and placed in bags with sterile rice substrate.…”

Peru is one of the main producers of fine aroma native cacao, expanding its areas considerably in recent years, which makes it necessary to seek adequate management alternatives to obtain advantageous yields. The present work had the objective of testing the influence of Trichoderma sp. endophytic strains on the agronomic characteristics of ecotypes of Theobroma cacao L. under nursery conditions, Cajaruro district, Utcubamba, Amazonas, Peru. The Trichoderma strains evaluated were Trichoderma breve; T. harzianum; T. longibrachatum; T. afrojarzianum, and Trichoderma sp. which were inoculated on cocoa seedlings of ecotypes CCN51; TCHS565; and Nativo fino de aroma. The variables evaluated were chlorophyll indices (at 30, 45, 60, and 70 days after planting), percentage of endophyte colonization, root hair development, trichomes on stems, and agronomic characteristics (plant height, number of leaves, stem diameter, root dry and fresh weight, root size, etc.). The results showed that the application of Trichoderma breve in the fine aroma native cocoa ecotype (T12) presented the highest chlorophyll index at 75 days after planting (DAP) with 43.53 ± 1.59 and 49.77 ± 2.42 for the apex and leaf base, respectively, with a percentage of colonization in the root hairs of 66.67%, and with better characteristics for the number of leaves with 12.00 ± 3.46. T12 showed positive influences for plant height, leaf number, and chlorophyll index. Treatments based on T. harzianum + CCN51 (T5) and T. afroharzianum + TSHS565 (T6) showed 100% colonization of the root hairs and trichomes on stems. Endophytic Trichoderma fungi are an alternative for organic production of fine aroma cocoa in Peru, improving the agronomic characteristics of the crop.

“…Ceramicum, Chlorosporum, Harzianum, Helium, Spinulosum, and Strictipile, but this treatment has not been fully accepted by other researchers ( Chen and Zhuang, 2017 ). Recently, Bustamante et al (2021) conducted multilocus phylogenetic analyses and four DNA-based methods to delimit the Trichoderma species of the Harzianum lineage that comprises most green-spored species.…”

Trichoderma spp. are a group of widespread fungi with important applications in many aspects of human life, but they are also pathogens that cause green mold disease on mushrooms. During a survey of mushroom cultivation in Guizhou, China, five strains of Trichoderma from three different localities were isolated from soil in mushroom bags of Hymenopellis raphanipes. The typical morphology of having gregarious, reddish stromata and gregarious phialides and the results of phylogenetic analyses based on a combined dataset of RPB2, TEF, and ITS gene sequences demonstrated that these green-spored Trichoderma belong to a new taxon, Trichoderma hymenopellicola. Pathogenicity tests by covering fungal mycelial blocks or soil mixed with spore suspension in mushroom bags showed similar symptoms to those in the field, and the same fungal pathogen had been observed and re-isolated from these symptoms, which fulfill Koch’s postulates. A primary screening test of nine common fungicides indicated that prochloraz-manganese chloride complex and propiconazole are the top two effective fungicides inhibiting the pathogen, whereas the former was further indicated as a suitable fungicide to control Trichoderma hymenopellicola, with a high inhibition ratio to the pathogen and low toxicity to the mushroom.
