Plant parasitic nematodes (PPNs) are the leading source of damage to crops in agricultural production and they can cause very serious yield reductions. The Tylenchida (Nematoda) constitutes most important group PPNs due containing a large number economically plant species. This study was conducted apple (Pyrus malus L.) walnut (Juglans regia orchards Bingöl (Turkey) between 2016 2017. For this ...

Population densities of nematodes in field soil without plants were monitored for 10 months following application of organic amendments to pots in a greenhouse. The four treatments consisted of three different kinds of organic amendments: homogeneous crop residues of maize (Zea mays, C:N = 48.0:1), Texas panicum (Panicum texanum, C:N = 32.9:1), or velvetbean (Mucuna pruriens, C:N = 18.6:1), plu...

The succession of soil nematodes from initial planting with Pinus sylvestris seedling to about 30-year-old pine plantations on coal mining sands in the Lusatian lignite-mining district near Cottbus (Germany) was studied and compared with the nematode fauna of a 40-year-old semi-natural pine forest on naturally formed sandy soil. The initial stage was primarily characterised by a very low abunda...

Previous reports suggest that fungivorous nematodes are the only trophic group in forest soils affected by elevated CO2. However, there can be ambiguity within trophic groups, and we examined data at a genus level to determine whether the conclusion remains similar. Nematodes were extracted from roots and soil of loblolly pine (Pinus taeda) and sweet gum (Liquidambar styraciflua) forests fumiga...

in order to identify the plant parasitic nematodes of tomato fields in northern khorasan province, 50 soil and root samples were collected during 2009 - 2010. nematodes were extracted by combined sieving and centrifugal-flotation method and processed to be transferred to glycerin. after preparing microscope slides, the morphological and morphometrical characters of the nematodes were studied us...

plant parasitic nematodes with various populations have found in the soil around the roots of plants. due to the biologic value of landscape and the importance of plant parasitic nematodes in the reduction of the growth of landscape plants; the study of identification, abundance and distribution of plant-parasitic nematodes in landscape of tehran city, iran was in interest. in order to dentific...

in order to identify the plant parasitic nematodes of pulse fields in northern khorasan province, 41 soil and root samples were collected from rhizosphere of pisum sp., phaseoulus sp., lens sp. during 2011 and 2012. the nematodes were extracted by combined sieving and centrifugal-flotation method of jenkins (1969) and transferred to glycerin by using method of de grisse (1969). the permanent sl...
