Antagonistas microbianos para biocontrol de la marchitez y su efecto promotor en el rendimiento de chile serrano

Abstract: Fusarium oxysporum y Rhizoctonia solani son agentes causales de la marchitez del chile y provocan pérdidas hasta 80% en el cultivo en México. El uso inadecuado de fungicidas químicos ha generado problemas de resistencia, esto no se observó con agentes microbianos, por lo que se evaluaron en el biocontrol de la marchitez del chile en parcelas experimentales donde se identificó a F. oxysporum y R. solani como agentes causales de la enfermedad. Trichoderma spp., Bacillus spp., mezcla de fermento propagativo micro… Show more

“…Espinoza-Ahumada et al [40] aimed to find more environmentally friendly alternatives to the wilting of chile pepper; they evaluated the application of −1 was applied for treatments one, two, and three, while the dose applied for thiabendazole was 0.5 kg.ha −1 . Field sowing is done with chile seedlings (10 cm), transplanted in 1.5 m double row beds.…”

“…The results generated by the microplate dilution method are consistent with the results obtained from indirect test by confrontation or dual test, such as shown in the following results against fungi isolated from crops as melon, pepper, and others, which are produced in different zones from Mexico. In melon crop, the root and stem rot disease is a big problem; in this context, Espinoza-Ahumada et al [40] studied the in vitro antagonist effects of Trichoderma spp. and found that T. asperellum have excellent biological activity against Fusarium strains, isolated from melon, shown in Table 3.…”

“…Varios estudios han demostrado que existe una interacción entre estos fitopatógenos para provocar esta enfermedad, además, de que algunas de sus sintomatologías son muy similares (Velásquez et al, 2001;Velásquez-Valle et al, 2017), como lo son; una menor cantidad de pelos radiculares (Espinoza-Ahumada et al, 2019), pudrición de raíces y tallos (Fig. 7-A), en ocasiones con presencia del signo de la enfermedad como lo es el micelio o esclerocios (Fig.…”
