“…In other studies, it was found to inhibit eggs from hatching by a nematostatic effect on the J2 of M. javanica, preventing early root invasion [45,46]. Application of this nematicide also reduced galling in beet plants infested by M. incognita by up to 86% [47]. However, in the 120 days after transplanting evaluation of our study, it performed poorly and matched the untreated control population.…”

The increase in the populations of root-knot nematode Meloidogyne enterolobii in various vegetables such as tomatoes grown under greenhouse conditions as well as increasing restrictions on the use of certain chemical nematicides have led to the search for new, effective management strategies, preferably ones that are sustainable biological alternatives. In this work, two formulations of the nematophagous fungus Metarhizium carneum, one concentrated suspension and one wettable powder, were evaluated under greenhouse conditions to reduce the M. enterolobii infestation in tomato plants. In addition, the effectiveness of the liquid formulation of M. carneum was compared with two biological and three chemical commercial nematicides. The results show that the two M. carneum formulations reduced the M. enterolobii population density by 78 and 66% in relation to the control treatment. In comparison, the liquid formulation of M. carneum and Purpureocillium lilacinum treatments reduced nematode population density by 72 and 43%, respectively, while for metam sodium preplanting applications followed by M. carneum applications during the tomato growth stage, the reduction was 96%. The alternate use of some chemical compounds plus the application of M. carneum as a biocontrol is a good starting strategy for managing M. enterolobii populations. These results confirm that M. carneum is a serious candidate for the short-term commercialization of an environmentally friendly biological nematicide.

The fungal microbiota associated with the roots and rhizosphere of plants represents a significant source of biocontrol agents against the root-knot nematode Meloidogyne spp. While some fungal genera have been studied extensively, others require more attention in terms of their identity and mechanisms of action against plant parasitic nematodes. Thus, the aim of this research was to demonstrate the in vitro and in vivo biocontrol potential of fungi isolated from the root and rhizosphere of guava plants against the root-knot nematode Meloidogyne incognita. We isolated four fungi (C5, C6, C7, and C10) from the root and rhizosphere of guava plants using the serial dilution method. These fungi were purified on potato dextrose agar and evaluated in vitro to assess their ability to parasitize M. incognita eggs and juveniles. Subsequently, the fungi were assessed for M. incognita control under nursery conditions in guava plants. The identity of the fungi with parasitic capacity and biocontrol potential was confirmed by amplifying and sequencing the ITS region, followed by Bayesian inference analysis. Results showed that the fungi corresponded to Talaromyces sayulitensis (C5), Myrothecium sp. (C6), Penicillium shearii (C7), and Beauveria bassiana (C10). Parasitism of M. incognita eggs was confirmed for all fungi, parasitism of juveniles occurred with T. sayulitensis (C5) and B. bassiana (C10). In guava seedlings treated with fungal isolates, a significant reduction in the number of eggs, juveniles, and nodules per gram of root was achieved. The biocontrol potential against M. incognita in guava seedlings was confirmed for different fungi associated with the root rhizosphere.
