The interactions of Meloidogyne javanica, Rotylenchulus reniformis, and Rhizobium sp. on cowpea seedlings were investigated. Upon simultaneous inoculation with the two nematode species, M. javanica invaded first but did not affect root invasion by R. reniformis. M. javanica populations increased less in competition with R. reniformis than when present alone. Preinvasion by R. renilormis signifi...

A soil temperature of 20 C was equally suitable for the invasion and development of M. hapla and M. javanica. However, M. javanica predominated in a mixed species infection at this temperature. Predominance increased with increasing mixed-species inoculum levels. Invasion by M. hapla was more density-dependent than M. javanica. M. hapla produced a greater incidence of terminal galls and lateral...

Resistance to a peanut-parasitic population of Meloidogyne javanica and an undescribed Meloidogyne sp. in peanut breeding lines selected for resistance to Meloidogyne javanica was examined in greenhouse tests. The interspecific hybrid TxAG-7 was resistant to reproduction of Meloidogyne javanica, M. javanica, and Meloidogyne sp. An Meloidogyne javanica-resistant selection from the second backcro...

A mixed population of Meloidogyne arenaria race 1 and M. javanica race 3 is reported on peanut from a field in Levy County, Florida. Confirmation of M. javanica on peanut is based on esterase and malate dehydrogenase isozyme patterns resolved on polyacrylamide slab gels following electrophoresis, and perineal patterns. Up to 29% of 290 individual females collected from peanut roots in the field...

The host suitability of five zucchini and three cucumber genotypes to Meloidogyne incognita (MiPM26) and M. javanica (Mj05) was determined in pot experiments in a greenhouse. The number of egg masses (EM) did not differ among the genotypes of zucchini or cucumber, but the eggs/plant and reproduction factor (Rf) did slightly. M. incognita MiPM26 showed lower EM, eggs/plant, and Rf than M. javani...

Fusarium oxysporum f. sp. ciceri and Meloidogyne javanica are important pathogens of chickpea. Interrelationships between Fusarium oxysporum f. sp. ciceri and M. javanica were investigated on 53 Fusarium wilt-resistant chickpea genotypes in pot experiments. All of the genotypes were susceptible to M. javanica. Fusarium wilt resistance in one genotype (ICC 12275) was ineffective in the presence ...

Root knot nematodes (Meloidogyne spp.) cause yield loss in all countries, of which, M. javanica, is the most widespread species in Iran. In order to identify M. javanica, 100 infected root and soil samples of root knot nematode were collected from different regions of Kerman province. After purification of populations and identification of M. javanica based on morphological and morphometerical ...

Second-stage juveniles (I2) of Meloidogyne arenaria consumed more oxygen (P </= 0.05) than M. incognita J2, which in turn consumed more than M. javanica J2 (4,820, 4,530, and 3,970 mul per hour per g nematode dryweight, respectively). Decrease in oxygen consumption depended on the nematicide used. Except for aldicarb, there was no differential sensitivity among the three nematode species. Meloi...

The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent. The egg pathogenic fungus Paecilomyces lilacinus is a unique strain with a wide range of activity against the most important plant parasitic nematodes. The aim of this study to evaluate the efficiency of P. lilacinus on parasitic nematodes Meloidogyne javanica on tom...
