“…F. solani presented a slower growth rate (0.4718 ± 0.00063 mm h −1 ). The results obtained in the present investigation were consistent with a study carried out by Miguel Ferrer et al [38], where different species of Trichoderma had superior mycelial growth compared with F. solani (4.71 cm d −1 ).…”

Strawberry wilt is a disease caused by Fusarium solani, which it provokes the death of the plant. Farmers mainly use chemical methods for its control, which has a negative impact on the environment and human health. Given the growing demand for organic agricultural products, compatible alternatives must be sought for disease management that can reduce the doses of fungicides. A combination of pesticides and biological control agents could be an alternative for the management of F. solani. Consequently, investigations on fungicide compatibility and synergistic effects are recommended in relation to the biological control of strawberry wilt. In this study, potential antagonism was calculated according to the class of mycoparasitism and the percentage inhibition of radial growth in order to later design a compatibility model of the different species of Trichoderma with three protective fungicides at different concentrations. The potential antagonism showed that Trichoderma asperellum presented high compatibility with the fungicides Captan and Mancozeb added in concentrations of 450, 900, and 1350 mg L−1. The use of antagonistic strains together with the fungicide Chlorothalonil in its three concentrations showed a negative effect on the growth of Trichoderma species, which caused low and null compatibility against the MA-FC120 strain of F. solani in vitro.

“…With the T4 treatment, the huacle chili seeds recorded a high germination percentage (99.6%), as a result of the previous management, and no impact by Fusarium spp. However, Nápoles García, 2019;Anguiano Cabello et al, 2019) and, as antagonists of Fusarium spp., they protect the huacle chili seeds (Martínez et al, 2013;Rojas et al, 2017, Pérez;García-Godos, 2019;Vásconez et al, 2022;Miguel-Ferrer et al, 2021).…”

“…Bacillus subtilis produces siderophores, indole compounds, and jasmonic acid, which promote stem height and a greater number of leaflets (Anguiano Cabello et al, 2019). As for Trichoderma harzianum, it can potentially control vascular fusariosis, resulting in a high germination percentage in miahuateco chili (Miguel-Ferrer et al, 2021) and mycoparasitism, through the production of antifungal enzymes with potential antibiotic characteristics. In addition, it increases the pod production (24%), root length (40%), and yield (23%) of chickpea crops (Martínez-Martínez et al, 2020).…”

Objective: To evaluate the effect of biological control agents (BCA) and two biological formulations (Bio-Terra and Bio-CNPR) against the phytopathogens found in the soil of huacle chili (Capsicum annuum) plantations, in order to obtain healthy seedlings. Design/Methodology/Approach: The following design variables were evaluated: germination (%), disease incidence (%), and survival (%). Stem height and root length were also evaluated. The experimental unit was a tray with n=30 seedlings per each treatments (T0, T1, T2, T3, and T4) and four repetitions. An analysis of variance (ANOVA) was used. Tukey’s mean test was applied (using the Minitab Statistical program version 20.0) in units that presented differences (p≤0.05). Results: The phytopathogenic microorganism Fusarium spp. was isolated from the soil of the plots cultivated with huacle chili. The T1 treatment recorded the best inhibitory effect against Fusarium spp.: it had 92.2% germination, 18.3% incidence of Fusarium spp., and 82% surviving seedlings (with an average height of 16 cm and a root length of 7.9 cm). The sterilization of the soil lead to T4 having the best results in germination, incidence, and survival, since Fusarium spp. did not damage huacle chili seedlings. In contrast, T0 did not prosper neither with BCA nor with biological products, since all the seedlings in non-sterile soil died. Study Limitations/Implications: A plastic barrier was placed between the trays with the chili seedlings to avoid cross-contamination between treatments. Findings/Conclusions: T1 (the BCA with nitrogen-fixing bacteria and B. subtilis) recorded the best counteracting results against the damage generated by Fusarium spp. Their antagonism allowed a high percentage of survival of huacle chili seedlings and encouraged plant development through the best root growth and height of the seedlings.

“…La inoculación de Trichoderma harzianum sobre la pudrición radicular de plántulas de pimiento redujo su daño y además promovió su crecimiento (Sofian et al, 2013;Tančić-Živanov et al, 2020;Bader et al, 2020;Miguel-Ferrer et al, 2021), igualmente el uso de Trichoderma asperellum cepa T34, tuvo una alta efectividad en el control de Phytophthora capsici en pimiento (Segarra et al, 2013;Herrera-Parra et al, 2017), similarmente, la aplicación de Trichoderma spp. en pimiento, controló el daño por Rhizoctonia (Ali, 2021).…”

En Araya Grande - Barranca, la páprika (Capsicum annuum L.) cv. Papri King se cultiva en suelos en proceso de degradación; hoy en día, para una buena cosecha, se utilizan altas dosis de fertilizantes y el uso constante de pesticidas tóxicos. El presente estudio tuvo como objetivo evaluar el efecto de la aplicación de ácidos húmicos co-inoculado con microorganismos eficaces y Trichoderma asperellum, T. viride y T. harzianum en el crecimiento de páprika en un suelo degradado. El experimento se instaló en el Centro de Investigación Los Anitos, en condiciones de casa malla, en macetas de 5 (l), bajo un diseño al azar, con 5 tratamientos y 6 repeticiones. Se evaluó la altura de planta, materia seca foliar y radicular a 60 días después del trasplante.
