{"title":"Comparative Evaluation of Organic Amendments Against Meloidogyne incognita in Tomato Seedlings","authors":"Sumit Vashisth,&nbsp;Aayush Kaushal","doi":"10.1111/jph.70387","DOIUrl":"https://doi.org/10.1111/jph.70387","url":null,"abstract":"<div>\u0000 \u0000 <p>Tomato (<i>Solanum lycopersicum</i> L.) is a globally important vegetable crop whose productivity is significantly constrained by root-knot nematodes (<i>Meloidogyne incognita</i>). The results revealed that all organic amendments significantly reduced nematode population and associated disease parameters compared to the untreated control. Among the treatments, neem cake applied at 2 t ha⁻¹ exhibited superior performance, recording the lowest nematode population in soil (80.00 and 112.22 J2/200 cc soil during 2023–2024 and 2024–2025, respectively), minimum number of egg masses and eggs per mass, and substantial population reduction (52.84%–58.93%). Neem cake also resulted in the lowest reproduction factor (0.62 and 0.42) and root-knot index (0.78 in both years), indicating effective suppression of nematode multiplication and disease severity. Furthermore, it enhanced seed germination, achieving the highest germination percentage (93.33% and 94.67%). The suppressive effects of organic amendments may be associated with the release of biologically active compounds, including ammonia, organic acids and phenolic compounds, during decomposition, as well as with stimulation of antagonistic soil microorganisms, as reported in previous studies. Although these mechanisms were not directly assessed in the present experiment, they provide plausible explanations for the nematode suppression observed following amendment application. Carbofuran showed efficacy statistically comparable to neem cake for several measured parameters; however, given the broader pesticidal activity of carbofuran and the increasing emphasis on environmentally sustainable pest management, the consistent performance of neem cake is noteworthy. The present findings therefore suggest that neem cake is a promising organic amendment for the management of <i>M. incognita</i> in tomato nurseries and could contribute to reducing reliance on chemical nematicides. Its potential benefits for soil organic matter and crop establishment further support its integration into sustainable and integrated nematode management programs, although these soil-health effects were not directly quantified in the present study.</p>\u0000 </div>","PeriodicalId":16843,"journal":{"name":"Journal of Phytopathology","volume":"174 5","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In October 2024, severe phyllody and virescence symptoms were observed in cucumber (<i>Cucumis sativus</i> L.) and summer squash (<i>Cucurbita pepo</i> L.) grown in Kırıkhan district, Hatay Province, Türkiye. Considering that all flowers on infected plants exhibited phyllody, yield losses in affected plants were estimated to reach up to 100%. A total of 27 symptomatic plant samples, including 19 squash and 8 cucumber plants, were collected and subjected to molecular analyses. Universal primer pairs F1/R0 and R16F2n/R2 were used to amplify the 16S rRNA gene (direct and nested PCR, respectively), and all symptomatic samples tested positive for phytoplasma presence, whereas no amplification was detected in asymptomatic control plants. BLASTn analysis of the 16S rRNA gene indicated that the detected phytoplasma belongs to ‘<i>Candidatus</i> Phytoplasma australasiaticum’. To further characterize the detected phytoplasma, multilocus analyses targeting the <i>secA</i>, <i>tuf</i>, <i>imp</i> and SAP11 genes were performed. BLASTn analyses of the representative 16S rRNA, <i>secA</i>, <i>tuf</i> and <i>imp</i> gene sequences revealed 99.93%–100% nucleotide sequence identity with reference strains of ‘<i>Ca</i>. P. australasiaticum’, cucumber phyllody phytoplasma, and tomato big bud phytoplasma. Phylogenetic trees based on the 16S rRNA, <i>secA</i>, <i>tuf</i> and <i>imp</i> genes showed that the Hatay isolates clustered within the peanut witches' broom subgroup (16SrII-D). To the best of our knowledge, this study represents the first molecular evidence of cucumber and summer squash phyllody associated with ‘<i>Ca</i>. P. australasiaticum’ (16SrII-D) in Türkiye. These findings expand current knowledge of phytoplasma diversity in cucurbit crops and demonstrate the value of multilocus sequence analyses for molecular characterization and phylogenetic inference.

This perspective complies recent observations on the emergence, distribution, epidemiology and management of SRBSDV in rice ecosystem of Haryana, where the disease was first reported during <i>kharif</i> 2022. No outbreaks were reported during the <i>kharif</i> 2023 and 2024 due to unfavourable climatic conditions, sustained effective preventive measures and increased awareness among farmers. However, in <i>kharif</i> 2025, the disease re-emerged across all major rice growing districts of Haryana, likely associated with favourable climatic conditions and decline in effective preventive measures, awareness and relatively casual attitudes among farmers, possibly resulting from the absence of outbreaks in the preceding 2 years. This re-emergence of SRBSDV suggests a potential phase of establishment under favourable agro-climatic conditions. Field observations revealed characteristic symptoms, including severe stunting, dark green erect leaves, excessive tillering, poor root development and poor/no panicle formation. The disease is transmitted by the white backed planthopper (<i>Sogatella furcifera</i>), whose migratory behaviour, rapid population build-up and interaction with environmental factors collectively play a crucial role in SRBSDV outbreaks. In several districts of Haryana, the infection level was found relatively low due to uprooting and destroying the stunted rice plants by the farmers. The estimated crop loss in affected fields remained relatively low, about 5% to 10%; however, the expanding spatial distribution and recurrent outbreaks indicate a high epidemic potential. Therefore, in this article, we have presented our perspectives on emerging risks of SRBSDV in the rice ecosystem of Haryana, India and management tactics, including cultural practices, vector surveillance and timely insecticidal interventions.</p>\u0000 </div>","PeriodicalId":16843,"journal":{"name":"Journal of Phytopathology","volume":"174 4","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148783711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
