“…In several preliminary in vitro experiments, it was found that B. subtilis and P. fluorescens strongly influenced the mortality and hatching of M . javanica , however, the pattern of influence of two organic amendments (vermicompost and BD) on the nematode was inconsistent ( Das et al., 2021a ; 2021b ). On the basis of these findings, organic amendments were integrated with the two bacteria in these trials.…”

“…In addition to J 2 , egg masses and hatching processes are important targets for nematode control in crops worldwide (Das et al, 2021) (Kepenekci & Saglam, 2015). In addition, greenhouse experiments showed a significant dose-dependent reduction in the number of M. incognita laid (> 85%) and in the number of galls (85%) on tobacco roots after J 2 exposure to CAREs from S. subinerme and S. lycocarpum, suggesting that the presence of CAREs in the soil affected the ability of J 2 to infect plant roots in vivo.…”

Brazilian crops are strongly affected by the root-knot nematode Meloidogyne incognita, which compromises food production and causes serious economic losses around the world. Synthetic nematicides are still some of the main control strategies for this pathogen, despite the high risk to human health and the environment. Therefore, sustainable biotechnology represents a viable alternative for nematode control. Plants of the Solanaceae family are present in several biomes and are a source of secondary metabolites of various chemical classes. In this context, the nematotoxic effect of crude aqueous root extracts (CAREs) of three Solanum species was investigated: Solanum americanum, S. subinerme and S. lycocarpum. CARE showed high nematicidal activity (94.6±9.2% mortality, p ≤ 0.001) against second-stage juveniles (J2) of M. incognita, even after heating to 50 °C. These CAREs also inhibited hatching of juveniles (98.4±0.7% of mortality, p ≤ 0.001) in addition to presenting a mean lethal dose of 336 μg ml-1. No toxic activity was observed against non-target organisms, such as fungi (Trichoderma harzianum and Trichoderma asperellum), yeast (Candida maltosa), nitrogen-fixing bacteria (Bradyrhizobium diazoefficiaens, B. japonicum), two strains of Azospirillum brasilense, AbV 5 and AbV 6 and Bacillus [2538 Ba]. Bioassay performed in a greenhouse demonstrated that CAREs of these species were effective in reducing the number of egg masses and galls (> 85%, p ≤ 0.0001), and did not show a phytotoxic effect on soybean seedlings. Our findings indicate that CAREs from plants of the Solanaceae family, especially S. lycocarpum, demonstrated nematotoxic activity on J2 and inhibited the hatching of Meloidogyne incognita eggs, representing an ecologically appropriate tool to control nematode infection in crops worldwide.

In this study, twelve aqueous extracts were assessed for their effects on egg hatching, mortality of second-stage juveniles (J2s) of Meloidogyne chitwoodi in vitro and growth chamber in 2020-2021. The mortality of the J2s increased with increasing exposure time and concentration with all extracts. Maximum mortality was observed in 10% extracts of Anethum graveolens (100%), Eruca sativa (100%), Vitex agnus-castus (98%), Asphodelus aestivus (96.4%), Eucalyptus camaldulensis (95.6%) after 24 hours and minimum mortality was found in 1% extracts of Laurus nobilis (6.6%) after 6 hours. Maximum suppression of hatching was found at 64.2%, 61.0%, and 59.4% with extract of A. aestivus, Nerium oleander, V. agnus-castus after 7 days, respectively. The pot experiments showed that gall index was the lowest in soils treated with Ficus carica, N. oleander, Zingiber officinale, and L. nobilis. The chemical composition of four aqueous extracts was analysed by using GC-MS, and the main components of L. nobilis, E. camaldulensis, F. carica, and N. oleander were identified as eucalyptol, 2-methoxy-6,10-dimethyl-dodeca-2E,6Z,10Z-trienoic acid, 12-acetoxy-, and dihydroedulan II. The study confirms the potential of mainly L. nobilis, E. camaldulensis, F. carica, and N. oleander extracts for the formulation of new products for controlling M. chitwoodi.
