Summary: Management of plant-parasitic nematodes encompasses various methods such as host plant resistance, crop rotation, cultural methods, and nematicide applications. However, the development of host resistance is laborious, while crop rotation and cultural methods present challenges. Sole reliance on chemical nematode suppression is not sustainable due to environmental and health concerns. Recent experiments have demonstrated that certain digestates possess nematode-suppressive capacity.

Summary: In this study, a CTL-like effector MiCTL1a of Meloidogyne incognita was characterized, which interacts with Arabidopsis catalases to modulate hydrogen peroxide homeostasis. This interaction allows the nematode to establish a parasitic relationship with its host by interfering with catalase activity, ultimately fine-tuning responses mediated by reactive oxygen species.

Summary: Meta-analysis was conducted to compare the efficacy of different nematicides on cotton yield protection and nematode suppression. The results showed that nematicides had no impact on nematode reproduction or root infection, but significantly increased cotton yield. The effectiveness of the nematicides varied depending on different moderator variables for different nematode species.

Summary: Soybean Cyst Nematode (SCN), Heterodera glycines Ichinohe, is a major soybean pathogen in the Mid-Atlantic region. The effectiveness of genetic resistance against SCN has declined, so additional management approaches are needed. Two experiments were conducted to study the effects of chemical and biological seed treatments on SCN. Seed treatments increased emergence percentage but did not significantly affect nematode populations or yield. However, one trial showed that pydiflumetofen + base seed treatment had the highest yield. Seed treatments may have potential as a part of integrated management for SCN.

Summary: The study explored the nematicidal activity of seed extracts from eight medicinally important plants against Meloidogyne incognita. The extracts of Taraxacum officinale and Bunium persicum were found to be the most effective in reducing the number of gall and egg masses, suggesting their potential as natural alternatives to synthetic nematicides.

Summary: This study investigated the impact of different seed priming treatments on the growth performance and reduction of nematode infestation in bread wheat. The results showed that seed priming with neem leaf extract was the most promising treatment, significantly reducing nematode infestation. Additionally, PSJN-1 exhibited maximum plant growth and reduced nematode infestation.

Summary: Soybean fields in Georgia were surveyed for plant-parasitic nematodes (PPNs) during the 2021 growing season. The most prevalent PPN taxa were the spiral nematode, lesion nematode, stubby root nematode, ring nematode, and root-knot nematode. The presence of soybean cyst nematode (SCN) was confirmed in nine counties, with different SCN populations showing varying levels of virulence on resistant soybean.

Summary: This study investigated the molecular mechanisms of induced resistance to Meloidogyne incognita by P. chrysogenum strain Snef1216 through seed coating. The results showed that P. chrysogenum strain Snef1216 could induce defense and plant growth-promoting responses. These findings are important for breeding nematode-resistant and biomass-enhancing cultivars of cucumber.

Summary: The study investigated the suppressive effect of powdered seeds of red radish, cress, and arugula on Meloidogyne incognita in tomato and cucumber. The results showed that the treatment with radish seed powder was more successful in controlling the nematode compared to cress and arugula seed powders.
