Special Issue Information

Dear Colleagues,

The challenge of managing plant-parasitic nematodes is a growing concern in sustainable agriculture, especially as these pests threaten global crop productivity and quality. Traditional chemical nematicides, although effective, often pose environmental and health risks, pushing researchers and producers alike to explore safer, eco-friendly alternatives. In recent years, innovative control strategies have emerged, emphasizing biological and integrated approaches for effective and sustainable nematode management.

This Special Issue focuses on alternative strategies that promote the natural resilience of plants against nematodes, including biological control agents, resistant crop varieties, and improved soil health practices. Biological control, through the use of nematophagous fungi, bacteria, and entomopathogenic nematodes, holds promise for reducing nematode populations while maintaining ecological balance. Additionally, crop rotation, cover cropping, and organic amendments offer avenues for suppressing nematode densities naturally by disrupting their life cycles and enhancing the growth of beneficial soil organisms.

We also encourage contributions on molecular and genetic techniques, such as RNA interference (RNAi) and CRISPR/Cas9, which target nematode-specific genes and disrupt their development and infectivity. Insights into plant–nematode interactions, root exudates, and soil microbiomes will provide a comprehensive understanding of these systems, paving the way for innovative and sustainable nematode control.

Through this Special Issue, we aim to advance knowledge on sustainable nematode management, contributing to resilient agroecosystems and improved crop productivity while minimizing reliance on chemical interventions.

Abstract
This study evaluated the chemical properties of phosphocompost extracts and their effectiveness in inducing tomato seedlings resistance to Meloidogyne javanica. Phosphocomposts: Sugar beet phosphocompost (PC-SB: CP2), green waste phosphocompost (PC-GW: CP3), and olive mill waste phosphocompost (PC-OMW: CP4), were utilized to produce [...] Read more.
This study evaluated the chemical properties of phosphocompost extracts and their effectiveness in inducing tomato seedlings resistance to Meloidogyne javanica. Phosphocomposts: Sugar beet phosphocompost (PC-SB: CP2), green waste phosphocompost (PC-GW: CP3), and olive mill waste phosphocompost (PC-OMW: CP4), were utilized to produce compost water extracts at concentrations of 1:5, 1:10, 1:20, and 1:100 g:mL and then applied as soil drenches for tomato seedlings one-week post-inoculation. The CP2 extract applied at a 1:5 dilution led to marked improvements in growth parameters, with plant height increasing by over 52.2%, shoot fresh biomass rising by approximately 52.44%, and shoot dry biomass showing a gain of 62.21%. Root biomass also rose by 33%. Chlorophyll a increased with CP4 at 1:5 and 1:100 (41.05% and 37.32%), chlorophyll b increased with CP3 at 1:5 and 1:10 (22.34% and 7.59%), while carotenes showed no variation. Polyphenols rose by 86.45–91.01% with CP2 from 1:5 to 1:20, and flavonoids increased by 64.90% with CP4 at 1:10. CP2 diminished the ultimate M. javanica population and reproduction factor by 171.43%, while CP4 at 1:20 decreased egg masses by 151.94%. The root gall index showed no variation. The chemical composition of phosphocomposts revealed that the strategic incorporation of diverse organic improvers (10%) in phosphocomposts yielded distinct nutrient signatures, with sugar beet waste enhancing PO43− (12.91 mg/L) and secondary macronutrients, green waste optimizing NO3− (69.91 mg/L) and SO42− (62.70 mg/L) availability, and olive mill waste producing superior micronutrient concentrations alongside dominant Ca (24.21 mg/L), K (392.50 mg/L), and P (9.17 mg/L) levels. Overall, the results underscore the potential of phosphocompost extracts as a viable, low-cost, and eco-friendly alternative to synthetic nematicides, offering a sustainable and resilient approach to M. javanica control while enhancing tomato plant growth.

The primary strategy for managing Nacobbus aberrans has traditionally relied on synthetic chemicals. However, increasing regulatory pressure on unsafe products has led to a growing research focus on nematicides. Despite this, chemical nematicides remain more effective than other control methods. Consequently, there is a pressing need to develop novel nematicides that are both effective and environmentally safer. This study aimed to evaluate the nematocidal efficacy of various synthetic molecules against the second-stage juveniles of N. aberrans, the false root-knot nematode. A total of fifty-eight synthetic derivatives were obtained and tested in vitro at a concentration of 500 µg/mL. The results identified the AGAz family as the most promising, with AGAz-3 (LC50: 52.7 µg/mL) and AGAz-4 (LC50: 103.22 µg/mL) surpassing the efficacy of chitosan. Our findings emphasize the strong potential of AGAz-3 and AGAz-4 as nematocidal agents, particularly for in situ applications in agricultural settings. Additionally, AGAz-3 demonstrates potential not only as a nematocidal agent but also as an incentive for related research exploring its analogs as effective ovicidal compounds and investigating its efficacy against other phytonematodes. Furthermore, compounds from the N-Sulfonyl-hydrazone and N-acyl-hydrazone series showed efficacy (>50%), warranting additional experiments to assess their effectiveness across the most important pest phytonematodes.
