“…Moreover, 71% of egg masses were infected at the end of the experiment. Another in vitro study involving P. lilacinum Argentinian isolates (LPSC# 876, Ls and Pv) showed antagonism against eggs of N. aberrans s.l., regardless of their embryonic state (Gortari and Hours, 2019). Hyphae surrounding the eggs were observed after 24 h, and the infection signs (invasion of hyphae, vacuolated, with deformed edges and without remains of the embryo and/or juvenile) became evident at 48 h. Meanwhile, conidiophores and conidia development took place between 48-72 h of culturing.…”

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.

“…Among the widely used and frequently studied biological control agents is Trichoderma spp. for their biocontrol activities and beneficial plant interaction Purpureocillium lilacinum (LUANGSA-ARD et al, 2011), is a natural soil fungus with a wide geographical distribution and recognized for its antagonistic activity on insects, eggs and females of plant parasitic nematodes (BARRA et al, 2015;GORTARI and HOURS, 2019;TOLEDO-HERNÁNDEZ et al, 2019). Purpureocillium lilacinum is also recognized as a producer of several pathogenicity factors such as enzymes, metabolic products of diverse nature and toxins (SHARMA et al, 2016;WANG et al, 2016).…”
