Meloidogyne enterolobii is an extremely important plant parasitic nematode. Tomato (Solanum lycopersicum) is an essential worldwide vegetable, and M. enterolobii poses a major threat to its production. The present research investigated the effects of different levels of inoculum density of M. enterolobii (100, 500, 1000, 1500, and 2000 second-stage juveniles (J2s)/plant) on tomato growth, physiological, and biochemical changes at 7, 14, 21, and 28 days post-inoculation (dpi). The negative impact of M. enterolobii on plants gradually increased when the inoculum level increased. Therefore, M. enterolobii population densities (500–2000 J2s/plant) significantly (p < 0.05) reduced plant growth, photosynthetic pigmentation, gas exchange, and chlorophyll fluorescence compared to control plants, while the low population density (100 J2s/plant) showed very little influence. Furthermore, plants with the highest M. enterolobii inoculum (2000 J2s/plant) exhibited a greater number of egg masses and galls. The inoculum densities of M. enterolobii exhibited a notable correlation with the significant elevation of both malondialdehyde (MDA) and hydrogen peroxide (H2O2) levels, which are recognized as very detrimental stresses in plants. Similarly, a rise in the activity of several defensive antioxidant enzymes, namely superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD), indicates the defensive mechanism used to combat the oxidative destruction produced by M. enterolobii. The specific activity of glutathione (GSH) and ascorbate (ASA) increased as potent antioxidant defense molecules in response to induced oxidative damage. In addition, our findings also demonstrated that the highest population density (2000 J2s/plant) increased the secondary metabolites responsible for scavenging oxidative stress in the plants. However, further research is required to explore the underlying reasons for this phenomenon and to develop efficient chemical or biocontrol strategies for managing M. enterolobii.

“…The temperature in the shed can reach more than 70℃, and the temperature at 15 cm of the ground under the film can still get more than 40℃ [21][22][23], and it is rarely applied on the open field. Studies have shown that the pesticide action of calcium cyanamide is mainly through its decomposition process to produce cyanamide substances, which can effectively inhibit and kill underground pests such as root-knot nematodes, pathogens, and weeds [24][25][26]. In this study, the open field was treated with Calcium Cyanamide, covered with black mulch film, and combined with sunlight exposure to explore the effect of Calcium Cyanamide disinfection, chemical fertilizer, and bacterial fertilizer on the control and growth of root-knot nematode of capsicum.…”

The cultivation of chili peppers in Zhanjiang City, Guangdong Province, China, has long suffered from root-knot nematode, which has caused significant economic losses. Commonly used chemical nematicides are highly toxic to humans and animals, and they can remain in the soil, damaging soil health and affecting the cultivation of subsequent crops. There is a need to find a green and safe alternative. Therefore, the present field experiment was conducted based on laboratory studies to evaluate the effect of treatment of open field with lime nitrogen followed by different fertilizers on the control of root-knot nematode in chili and its growth. The highest preventive effect against root-knot nematode was found to be 53.37% after applying lime nitrogen treatment in the open field, and the highest preventive effect was 80.42% when combined with fertilizers. Compared with the control, the maximum increase in soil temperature was 8℃, and the pH value of the soil was increased from 5.83 to 7.52, effectively improving soil acidification and structure and increasing soil fertility. The present results show that this technology can meet the expectations when applied on the open floor, but it needs to be combined with other measures. It can be carried out in combination with the summer fallow period.
