Many studies of entomopathogenic nematodes (Heterorhabditidae and Steinernematidae) have reported that only a small proportion (typically < 40%) infective stages (dauers), even under apparently ideal conditions, actually infect host. The 'phased infectivity hypothesis' is most frequently invoked to explain this pattern low infection with nematodes. It proposes at given point in time not all individuals are infectious i.e. infectiousness delayed some individuals. We tested experimentally...
Abstract Vetiver, a nonhost grass for certain nematodes, was studied the production of compounds active against southern root-knot nematode, Meloidogyne incognita . In laboratory assays studying effects on second-stage juvenile (J2) activity and viability, crude vetiver root shoot extracts were nematotoxic, resulting in 40% to 70% J2 mortality, also repellent J2. Vetiver oil did not exhibit these assays. Gas chromatography-mass spectrometry analyses three ethanol commercial determined that...
Summary The legume cavalcade, Centrosema pascuorum , is used extensively as a cover crop and component of conservation agriculture systems. It also an attractive rotation or for the management root-knot nematodes (RKN; Meloidogyne spp.) it non-host. RKN are persistent pests that well known to be difficult control. However, mechanisms governing non-host status cavalcade unknown. current study established leaves toxic either aqueous extracts soil amendments. Bioassays conducted using javanica...
Root-knot nematodes have caused severe damage to chili grown in Ubon Ratchathani province, Thailand, for a long time. As yield losses by these root-knot been evaluated and effective control methods sought, accurate identification of the species is urgently needed. Thus, this study focused on nematode using morphological molecular techniques. A field survey damaged plants was carried out 4 districts province: Lao Suea Kok (LS), Mueang (AM), Muang Sam Sip (MS) Det Udom (DA). This revealed that...
Abstract Samanea saman (Jacq.) Merr., commonly known as rain tree, is a crucial shade tree with traditional medicinal properties. In our study, 50 soil samples were collected around the rhizosphere of in Bangkok, Pathum Thani, Uttaradit, Khon Kaen and Ubon Ratchathani Provinces Thailand. Meloidogyne populations only found from Mueang district, Province 30‐year‐old exhibited root gall symptoms caused by root‐knot nematodes ( ) on its adventitious roots. The species identified based...
The induction of systemic acquired resistance (SAR) in pineapples (Ananas comosus) was studied as shown by the up-regulation PR-1 gene (the SAR marker) and examination effect on reniform nematode, Rotylenchulus reniformis. Real-time polymerase chain reaction assay performed using degenerate primers designed from genes several monocotyledonous (monocots) dicotyledonous (dicots) plants. A 266 bp cDNA band evident only plants treated with inducer, acibenzolar-s-methyl. This sequenced found to...

The rice root nematodes, Hirschmanniella spp., are considered the predominant plant-parasitic nematode in clay soils of Battambang's lowland fields Cambodia. In this study, we compared population dynamics, yield parameters, and soil organic matter content under conservation agriculture (CA) system with conventional tillage systems green manure management (GMCT) or plough-based (CT) systems. Results demonstrated that GMCT for one year (GMCT1) long-term CA seven years (CA7) reduced densities...
The rice root nematodes, Hirschmanniella oryzae and H. mucronata, are serious widespread threats to global production, especially in tropical subtropical zones. Reliable efficient identification of these nematodes is vital nematode control management. In this current study, 36 soil or samples were collected from fields located Pathum Thani province used for extraction. results demonstrated that sp. was found all paddy fields, Muang District, where RD47 cultivars grown at pH 5.9. Molecular...
The purpose of this study is to describe the strategy pursued by Government Thailand in collaboration with existing stakeholders increasing competitiveness SMEs amidst invasion foreign manufacture-based products. method used observation and in-depth interviews at SME product canters, marketing places tourist destinations, related parties. Observations were made for 5 years 2018-2023, however, observations January-March 2023. results analysis show that very good due support from universities,...
Numerous phytoparasitic nematodes have been identified in Thailand’s paddy fields, which routinely cause substantial reductions rice crop yields. However, effective strategies for their management yet to be documented. In this study, cavalcade legume was used as a soil amendment RD41 fields examine its effects on the nematode community, properties, and yield components compared untreated control plots. The results demonstrated that population densities of plant-parasitic (PPNs) order...
