The potato rot nematode, Ditylenchus destructor, is a very destructive nematode pest on many agriculturally important crops worldwide, but the molecular characterization of its parasitism of plant has been limited. The effectors involved in nematode parasitism of plant for several sedentary endo-parasitic nematodes such as Heterodera glycines, Globodera rostochiensis and Meloidogyne incognita h...

Five field trials were conducted in Italy in 1983 and 1984 to test the efficacy of isazofos and benfuracarb in controlling Heterodera carotae on carrot, Ditylenchus dipsaci on onion, and Meloidogyne javanica on tomato. Methyl isothiocyanate (MIT) was tested against H. carotae and M. javanica. Single (10 kg a.i./ha) and split (5 + 5 kg a.i./ha) applications of isazofos gave yield increases of ca...

abstract in order to identify biodiversity of  plant parasitic nematodes in alfalfa and no comprehensive research about the plant parasitic nematodes associated with alfalfa,during 2002-2003, 33 soil samples were collected from alfalfa fields of several locations in alfalfa fields in ahar region, partly biodiversity plant parasitic nematodes in this crop were identified.nematodes extracted by c...

Population densities of D. destructor on embryo explants of 22 peanut genotypes grown in vitro were compared with those in roots and seeds of the same genotypes grown in the greenhouse. During the first 8 weeks after inoculation, the optimum incubation period was 6 weeks for maximum reproduction of Ditylenchus destructor on embryo explants of peanut (Arachis hypogaea L. cv. Sellie) inoculated w...

The motility and survival of Orrina phyllobia fourth-stage juveniles (J4) were examined in NaCl, sucrose, and synthetic soil solutions. Synthetic soil solutions (SSSs) contained Na, K, Ca(2), Mg(2), Cl, and NO at relative concentrations identical to those in a known agronomic soil. Nematode activity was dependent on solute composition and on water potential. In all solutions, motility ceased at...

Abstract The stem nematode, Ditylenchus dipsaci , is a severe pest in European sugar beet production. In France, Germany, and Switzerland, D. damage varies among specific geographic areas. this study, the reproduction potential of four geographically distinct populations was determined using sterile carrot disc cultures. addition, virulence pathogenicity were investigated in-vivo beet. No diffe...
