“…At the end of 68 d, all treatments achieved a reduction of females greater than 80 % compared to the control, where the best result was Oxamyl with 92.47 %, although among the two strains evaluated, T. erinaceum was the best performer with 86.74 % (Figure 2). Applications with T. harzianum and T. virens also achieved a decrease in the number of M. incognita females in tomato crops, with a percentage higher than 80 % (Pinzón-Espinoza et al, 2015;Cetz-Chi et al, 2018). Medeiros et al (2017) reported that T. atroviride is able to activate a defense system in response to the attack of M. javanica on tomato plants, where the number of adults and galls was significantly reduced, even without establishing direct contact with the nematode.…”

In this study, the antagonistic potential of Trichoderma erinaceum 10-15 and T. virens 32-09 against the nematode Meloidogyne incognita was evaluated in tomato (Solanum lycopersicum L.) plants. A solution of 106 conidia mL-1 of each strain was inoculated on tomato plants, and the variables of nematode control, galling index, eggs per gram of root, and females per gram of root were determined. The in vitro antagonism of Trichoderma filtrates on the hatching of eggs and J2 juveniles of M. incognita was evaluated. The results were used for analysis of variance and comparison of means using the Tukey method (p ≤ 0.05). Control variables of the phytopathogen on S. lycopersicum were determined by measuring the area under the disease progress curve (AUDPC), the Weibull parameter, the coefficient of determination, and the final severity of root damage. T. erinaceum 10-15 showed a greater inhibitory effect on M. incognita, relative to T. virens 32-09. Both strains evaluated showed significant differences in comparison to the uninoculated control, resulting in a 60 % reduction in juvenile stage mobility and egg hatching, as well as greater control of the phytonematode in the AUDPC variables, Weibull parameter, and final severity under controlled conditions. The strain T. erinaceum 10-15 showed a better antagonistic effect on egg formation at 68 days, at 60.3 %, and on reducing the number of M. incognita females with at 60 days, at 80.6 %. Both T. erinaceum 10-15 and T. virens 32-09 were found to be potential biocontrol agents of M. incognita in S. lycopersicum.

“…Este resultado fue estadísticamente igual al tratamiento 1x10 7 conidios mL -1 (Cuadro 2). Cetz-Chi et al (2018) reportaron incrementos en el crecimiento de plantas de jitomate, con ganancias de altura entre 4.4 y 14.2 % cuando se inocularon con especies nativas: T. virens (Th33-59 y Th26-52) y T. simmonsi (Th33-58), Th33-59 de T. virens incrementó el volumen radical y el peso seco de raíz con respecto al testigo. Ruiz-Cisneros et al (2018) observaron incrementos en altura de planta, diámetro de tallo y longitud de raíz en plantas de jitomate cuando se inocularon con T. asperellum, T. harzianum y T. longibrachiatum en concentraciones de 10 6 conidios mL -1 .…”

Corynespora cassiicola is a pathogen that causes lesions in different organs of tomato crops. For its control, synthetic fungicides are used that require more than one application. Trichoderma spp. is a highly interactive saprophytic fungus in the rhizosphere known as a biological control agent against plant diseases and promoter of plant growth due to its different modes of action. The effect on physiological and growth variables in Solanum lycopersicum plants inoculated with spore concentrations 1x100, 1x105, 1x106, 1x107 and 1x108 of Trichoderma asperellum Ta-13-17 and Fithan®, (as a commercial control) was evaluated. As a biocontrol agent for C. cassiicola under protected conditions. The 1x106, 1x108 and Fithan® treatments obtained the highest photosynthetic rates with 20.7, 20.6 and 19.6 µmol m-2 s-1 respectively. The 1x108 conidia mL-1 treatment obtained the highest means in the photosynthesis variables 20.6 µmol m-2 s-1, yield 1347.02 g per plant and presented a lower percentage of final severity, lower speed in the distribution of the disease and lower accumulation of area under the disease progress curve.

“…Por ejemplo, T. harzianum contribuyó a una mejor protección de plantas de cacahuate contra la infección de Sclerotium rolfsii en comparación con un fungicida (Michel-Aceves et al, 2013). Por otro lado, T. virens contribuyó a reducir la formación de agallas, el número de huevos y hembras del nematodo fitopatógeno Meloidogyne incognita en Solanum lycopersicum (Chi et al, 2018). Adicionalmente, se demostró el potencial biológico de T. asperellum para controlar el desarrollo de antracnosis ocasionada por Colletotrichum gloeosporioides en frutos de mango (Santos-Villalobos et al, 2013).…”

Background. Trichoderma is a cosmopolitan genus of fungi with beneficial species that help both to improve the plant rhizosphere and combat pathogens in economically important crops. Due to its importance in the agricultural biotechnological field, the morphological and molecular identification of Trichoderma species is of interest; however, currently the information on identification, biocontrol and its applications in agriculture is scattered. Objective. The objective of this review was to carry out an exhaustive analysis on the identification of Trichoderma, as well as an analysis of biocontrol studies and applications of Trichoderma in agriculture in Mexico. Methodology. A bibliographic review of Trichoderma was carried out in the following databases: Scopus, Science Direct, NCBI, Google Scholar, Pubmed and USDA. The keywords used were Trichoderma, identification, morphology, molecular, antagonism, biocontrol, agricultural use, agricultural importance, and Mexico. The collection of information on Trichoderma species in Mexico was considered during the period from 2005 to 2022. Results. In Mexico, 42 species reported to date of Trichoderma based on morphological characteristics were found, the main identified species are T. harzianum, T. asperellum and T. viride; according to the ITS barcoding marker and tef1α gene region, 17 species reported to date have been identified at the molecular level. The main species reported are T. asperellum and T. harzianum. Additionally, the most reported species as antagonists are T. asperellum and T. harzianum, the latter being the one that is mostly marketed in biological products. Implications. Currently the species T. asperellum and T. harzianum stand out in identification, biocontrol, and application in agriculture. Conclusions. Morphological identification alone is difficult; recently in Mexico, the identification of Trichoderma species is carried out at an exhaustive level, complementing the morphological identification with molecular identification. At present, reports on the diversity of Trichoderma species have increased in identification, biocontrol, and applications in the agricultural area.
