Developing resistant cultivars/rootstocks remains an important strategy for the sustainable management of plant-parasitic nematodes in integrated pest management (IPM) systems. Controlling the citrus nematode is challenging due to its wide host range and high adaptability. Although commonly used, chemical nematicides increase production costs and pose risks to human health and the environment. In this study, we separately evaluated the response of five commonly used citrus rootstocks, Citrus paradisi (M.) × Poncirus trifoliata (L.) Raf. (Citromelo), P. trifoliata (L.) Raf. (Poncirus), Citrus jambhiri Lush (Rough lemon), C. volkameriana Ten. & Pasq. (Volkamer lemon), and Citrus aurantium L. (Sour orange), to T. semipenetrans infection. In parallel, we evaluated the biocontrol potential of two bacterial strains, Bacillus safensis Q.en and Pseudomonas chlororaphis P.en, on the susceptible 'Sour Orange'. The results showed that T. semipenetrans exhibited the highest reproduction on 'Volkamer lemon' (275 females/g root and 1,150 second-stage juveniles [J2s]/200 g soil), whereas 'Citromelo' showed the strongest resistance (8 females/g root and 220 J2s/200 g soil). Application of the bacterial agents to 'Sour Orange' significantly reduced the number of females on roots and juveniles in the soil, while also improving plant growth parameters compared to untreated controls. Our findings demonstrate the individual potential of using resistant rootstocks or biocontrol agents as economical, effective, and environmentally safe components for managing T. semipenetrans. The resistant genotypes identified may also be useful in future breeding programs.","PeriodicalId":16475,"journal":{"name":"Journal of nematology","volume":"57 1","pages":"20250064"},"PeriodicalIF":1.4,"publicationDate":"2026-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12860889/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146105896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reports suggested that Ditylenchus dipsaci in yellow pea export was likely the nonquarantine species D. weischeri, a Canada thistle (Cirsium arvense) parasite. To determine if D. dipsaci is found in pulse plants and understand nematode distribution in the Canadian Prairies, a survey was conducted in commercial yellow pea, lentil and chickpea fields in Alberta, Saskatchewan, and Manitoba. Samples of pulse and thistle plants (flowers or pods, stems and leaves) and soil were collected from 94 fields. Nematodes were identified by morphological features and molecular analyses (species-specific PCR, PCR-RFLP, and sequencing of the partial 18S, 28S and ITS of the rDNA gene). High densities of plant-parasitic nematodes - Pratylenchus, Paratylenchus, Helicotylenchus and Telotylenchinae - were found in several fields. Ditylenchus weischeri, a parasite of thistles and not pulse crops, was recovered from 20 fields across Alberta, Saskatchewan and Manitoba; D. dipsaci was found in pods of one yellow pea field in Manitoba. These results confirm the high prevalence of D. weischeri on creeping thistle in pulse fields and the near absence of the quarantine pest D. dipsaci.","PeriodicalId":16475,"journal":{"name":"Journal of nematology","volume":"57 1","pages":"20250040"},"PeriodicalIF":1.4,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12768485/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145911945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It focused on commonly planted soybean varieties, as well as University of Missouri varieties with reported resistance to the reniform nematode. Field trials were conducted in 2022 and 2023 at two locations in Louisiana. The resistant soybean varieties consistently suppressed reniform nematode soil population densities, achieving population reductions of 73% in 2022 and 72% in 2023, relative to the commercially planted soybean varieties. Resistant soybean varieties generally achieved higher yields than the commercial soybean varieties. This trend was consistent across the field trials conducted over both years.
