In greenhouse tests using potted grape plants three nematicides, aldicarb 10 G at 4.5 ai/ha, phenamiphos 15 G at 22 kg ai/ha, and oxamyl liquid at 4.5 kg ai/ha, were tested against Xiphinema index on 'Thompson Seedless' grape. Different timings for chemical treatments and X. index inoculations were used to determine some of the aspects of the mode of action. When nematodes and nematicides were ...

In this study, we aimed to determine the nematode diversity in soils from olive orchards İzmir, Manisa, Çanakkale, and Balıkesir provinces. For purpose, a survey was carried out 2021-2022; each orchard, soil samples were collected 0-60 cm depth, nematodes extracted by modified Baermann Funnel method. Thirty-seven genera of (Achromodora, Acrobeles, Acrobeloides, Alaimus, Aphelenchus, Aphelenchoi...

Tomato ringspot virus (ToRSV), Tobacco ringspot virus (TRSV) and Tobacco rattle virus (TRV) are transmitted to healthy plants by viruliferous nematodes in the soil. A method was developed for extraction of genomic viral RNA from virus particles carried within nematodes and a sensitive nested RT-PCR detection assay. The procedure has been adapted to microscale for handling multiple samples. This...

Summary A new species of the dagger nematode, genus Xiphinema , was recovered from rhizospheric soil samples collected rangelands in Semnan province, north-central Iran, and described based upon both morphological molecular data. sangesarense n. sp. is characterised by 3.7-4.8 mm long females having 136-154 μ m odontostyle, 74-87 odontophore, two equally developed genital tracts with crystalloi...

The filamentous fungus Ashbya gossypii is a cotton pathogen transmitted by insects. It is readily grown and manipulated in the laboratory and is commercially exploited as a natural overproducer of vitamin B2. Our previous genome analysis of A. gossypii isolate ATCC10895, collected in Trinidad nearly 100 years ago, revealed extensive synteny with the Saccharomyces cerevisiae genome, leading us t...

Previous reports of crop losses to plant-parasitic nematodes have relied on published results of survey data based on certain commodities, including tobacco, peanuts, cotton, and soybean. Reports on crop-loss assessment by land-grant universities and many commodity groups generally are no longer available, with the exception of the University of Georgia, the Beltwide Cotton Conference, and sele...

One hundred and nine soil samples were collected in 69 different localities along two transects, one North– South, about 900 km in length, and the other East–West (750 km in length), across Senegal and Gambia. The first transect followed a rainfall gradient and the second a human density gradient. The relationship between carbon content, C/N ratio and soil type on the abundance and species dist...
