Plant nematode disease management is still a difficult problem in agricultural production. To develop novel green nematicides, pyridazine compounds with nematicidal activities against Ditylenchus destructor (D. destructor), Bursaphelenchus xylophilus (B. xylophilus), Aphelenchoides besseyi (A. besseyi), and Meloidogyne incognita (M. incognita) were discovered. The LC50 values of compound C2 7.1 3.4 mg/L D. A. besseyi, respectively. Compound not only caused an adverse oxidative stress response nematodes, resulting intestinal damage, but also significantly inhibited egg hatching destructor. may lead to decreased cellular tolerance antioxidant function by downregulating the differential gene heat shock 70 kDa protein, thereby accelerating cell litter process ultimately leading death nematode. can serve as potential nematicide worthy further study future.

To develop new nematicides, amide derivatives with oxazole/isoxazole were synthesized via scaffold-hopping as succinate dehydrogenase (SDH) inhibitors. The nematicidal activities of these target compounds tested against Bursaphelenchus xylophilus, Aphelenchoides besseyi, and Ditylenchus destructor. Some the showed excellent activities. Compound B21 had LC50 values 3.2 mg/L for B. 11.5 A. 10.5 D. exerted a pronounced inhibitory effect on feeding, reproduction, embryonic development capabilities while concurrently triggering deleterious oxidative stress responses within nematodes. These reactions led to intestinal damage eventually death exhibited strong hydrophobic interactions residues Arg-76, Val-103, Pro-193, Ile-242 SDH. Additionally, significantly inhibited SDH an IC50 value 6.5 μmol/L.

To discover novel structural nematicides, 79 amide compounds containing 1,2,4/1,3,4-oxadiazole moiety were designed, synthesized, and evaluated for nematicidal efficacy against second-stage juveniles of Bursaphelenchus xylophilus (B. xylophilus). Notably, some exhibited superior efficacy, example, the LC50 values 11, 39, 40, 48, 49, 51, 52, 54 7.4, 31.0, 35.3, 10.3, 12.7, 6.9, 21.5, 52.2 mg/L, respectively, with activities significantly surpassing that tioxazafen (79.3 mg/L). Compound 51 multifaceted activity through suppression motility, feeding, reproduction, combined induction oxidative stress. reduced nematode protein content impaired antioxidant capacity. Meanwhile, compound demonstrates binding energy interaction mode succinate dehydrogenase (SDH), showing potent SDH inhibition (IC50 = 15.0 μmol/L). Therefore, which may become a potential inhibitor, interferes metabolism by inhibiting activity, resulting in death.

Abstract BACKGROUND The pine wilt disease (PWD) caused by Bursaphelenchus xylophilus is considered the ‘cancer’ of trees, and protecting forests from destructive impact nematode remains a significant challenge. Chemical control one most effective methods for managing plant nematodes. Developing new nematicides an strategy urgent need management. RESULTS Amide derivatives containing 1,2,4‐oxadiazole were designed synthesized through scaffold‐hopping strategy. Some target compounds exhibited nematicidal activities. For example, compound F3 showed half‐maximal lethal concentration (LC 50 ) value 3.63 mg/L against . Compound not only significantly inhibited hatching eggs, but also reduced feeding, reproduction, motility Additionally, induced accumulation lipofuscin, lipids, reactive oxygen species (ROS) in , leading to harmful oxidative stress responses. severe damage intestinal barrier, led shrinkage surface. Interestingly, favorable interaction pattern with succinate dehydrogenase (SDH) was similar fluopyram SDH. may inhibit activity SDH, blockage electron transfer respiratory chain, thereby resulting death. CONCLUSION can serve as potential lead SDH inhibitor, further molecular structure optimization discover future. © 2025 Society Industry.

Pine wilt disease, caused by Bursaphelenchus xylophilus (Steiner & Buhrer, 1934) Nickle 1981, poses a significant threat to the safety of pine forests in world. Currently, available nematicides for controlling this disease are limited. Finding new is crucial effective prevention and control disease. In study, we discovered that tetramycin B3, derived from Streptomyces ahygroscopicus, demonstrated promising effect on The LC50 values B3 at 24, 48, 72 h were 26.49, 23.37, 12.79 μg/mL, respectively. Tetramycin significantly inhibited feeding growth rate B. low concentrations while also increasing ROS (reactive oxygen species) production lipid accumulation. Furthermore, markedly activity detoxifying protective enzymes. Transcriptome metabolome analyses indicated affected expression genes related lysosomes, autophagy, metabolism xylophilus. Additionally, delayed onset results showed influenced defense responses trees induced produce disease-resistant mechanisms. Future research will focus further elucidating mechanism action against verifying gene functions identified through transcriptome screening.
