Several formulations of 1,3-dichloropropene and chloropicrin were compared with a methyl bromide/chloropicrin formulation for nematode control on tomatoes (Lycopersicon esculentum Mill.) grown on a sandy soil in Immokalee, Collier Florida Agricultural Experiment Station Journal Series No. N-01294. This work was supported by funding from the United States Department of Agri culture Specific Coop...

The aim of this review was to undertake a survey of researchers working with plant-parasitic nematodes in order to determine a 'top 10' list of these pathogens based on scientific and economic importance. Any such list will not be definitive as economic importance will vary depending on the region of the world in which a researcher is based. However, care was taken to include researchers from a...

in this study, high biocontrol potentially bacillus isolates, against root knot nematode were evaluated from viewpoint of biofilm formation and root colonization in vitro. among 139 bacillus isolates from tomato rhizosphere of several regions of razavi khorasan, 15 strains which show more ability to prevent egg hatch and cause larvae mortality of meloidogyne javanica, were tested in biofilm ass...

A new root-knot nematode, Meloidogyne aquatilis n. sp., attacking the roots of Spartina pectinata Link growing in the Ottawa River is described and illustrated. Meloidogyne aquatilis is distinguished from M. graminis by the light brown body color and by the absence of perineal lateral fields in the female. The male differs by the shorter stylet and by the hemizonid being separated by 7-9 annule...

rhizosphere soil samples were collected from olive orchards of golestan, guilan, zanjan and qom provinces. fluorescent pseudomonad strains were isolated from the collected samples on king’s b medium and their phenotypic features characterized as based on the standard bacteriological methods. for all the tested strains oxidase reaction, fluorescent pigment, growth at 4?c and arginine dihydrolase...

Pulsatilla koreana, a species endemic to Korea, is an important herb used in traditional medicine to treat amoebic dysentery and malaria. In the present study, 23 oleanane-type triterpenoid saponins 1-23 and eight lupane-type triterpenoid saponins 24-31 were isolated from the roots of P. koreana. Their structures were elucidated on the basis of spectroscopic data. The methanol extract and isola...
