“…Esto indicó que la inoculación de consorcios de HMA, potenció la asimilación de carbono, no así la inoculación con Trichoderma. Considerando que los tratamientos con HMA también incrementaron la mayoría de las variables de crecimiento y las características de los frutos, se sugiere que a pesar de la presencia de ne-matodos los mecanismos que utiliza la planta durante la simbiosis con HMA mejora la síntesis de fotoasimilados, los cuales son canalizados en las diversas formas de crecimiento de la planta (Parihar et al 2020, Bernardo et al 2021.…”

Los nematodos agalladores afectan la producción de chile ha- banero (Capsicum chinense Jacq.) y el uso de microorganimos antagonistas son una opción para su control. El objetivo fue evaluar consorcios nativos de hongos micorrízicos arbusculares (HMA) y Trichoderma spp. (TRI) para el manejo de M. incognita (Mi) en C. chinense. En condiciones protegidas se establecieron cinco tratamientos: HMA + Mi, TRI + Mi, HMA + TRI + Mi, nematicida Vydate 24% (Oxamil) + Mi y un control solo con Mi. Cada tratamiento tuvo 15 repeticiones. El tratamiento HMA + Mi, disminuyó el índice de agallamiento, el número de huevos y hembras en un 56, 48 y 26.29% con relación al Oxamil. El mayor crecimiento de las plantas se logró con HMA + Mi con efectos superiores al nematicida y el control. Los tratamientos HMA + Mi y HMA + TRI + Mi promovieron mejor funcionamiento fisiológico de las plantas.

Plant-parasitic nematodes (PPNs) are among the most notorious and underrated threats to food security and plant health worldwide, compromising crop yields and causing billions of dollars of losses annually. Chemical control strategies rely heavily on synthetic chemical nematicides to reduce PPN population densities, but their use is being progressively restricted due to environmental and human health concerns, so alternative control methods are urgently needed. Here, we review the potential of bacterial and fungal agents to suppress the most important PPNs, namely Aphelenchoides besseyi, Bursaphelenchus xylophilus, Ditylenchus dipsaci, Globodera spp., Heterodera spp., Meloidogyne spp., Nacobbus aberrans, Pratylenchus spp., Radopholus similis, Rotylenchulus reniformis, and Xiphinema index.

“…More recently, information about the effect of the interaction between N. aberrans s.l. and AMF on pepper plant physiology and biochemistry was described ( Bernardo et al., 2020 ). These authors analysed the potential of three AMF ( F. mosseae, R. intraradices B1 and A2) in the nematode control.…”

Sustainable strategies for management of the “false root-knot nematode” Nacobbus spp.

The genus Nacobbus, known as the false root-knot nematode, is native to the American continent and comprises polyphagous species adapted to a wide range of climatic conditions. Alone or in combination with other biotic and abiotic factors, Nacobbus spp. can cause significant economic yield losses on main food crops such as potato, sugar beet, tomato, pepper and bean, in South and North America. Although the genus distribution is restricted to the American continent, it has quarantine importance and is subject to international legislation to prevent its spread to other regions, such as the European Union. The management of Nacobbus spp. remains unsatisfactory due to the lack of information related to different aspects of its life cycle, survival stages in the soil and in plant material, a rapid and reliable diagnostic method for its detection and the insufficient source of resistant plant genotypes. Due to the high toxicity of chemical nematicides, the search for alternatives has been intensified. Therefore, this review reports findings on the application of environmentally benign treatments to manage Nacobbus spp. Biological control strategies, such as the use of different organisms (mainly bacteria, fungi and entomopathogenic nematodes) and other eco-compatible approaches (such as metabolites, essential oils, plant extracts, phytohormones and amendments), either alone or as part of a combined control strategy, are discussed. Knowledge of potential sources of resistance for genetic improvement for crops susceptible to Nacobbus spp. are also reported. The sustainable strategies outlined here offer immediate benefits, not only to counter the pathogen, but also as good alternatives to improve crop health and growth.
