verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

Twelve soil drenches over a period of 30 days with DBCP concentrations of 40 microg/ml did not completely prevent infection of tomato plants by root-knot nematode juveniles. Repeated DBCP drenches of 40 microg/ml halted gall development during the drenches, but 10 days after drenching was discontinued galls were apparent. DBCP drenches at 200 microg/ml prevented tomato root development, and 40 ...

The root-knot nematode Meloidogyne incognita was controlled more effectively and yields of host plants were greater when Paecilomyces lilacinus and Pasteuria penetrans were applied together in field microplots than when either was applied alone. Yields of winter vetch from microplots inoculated with the nematode and with both organisms were not statistically different from yields from uninocula...

Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest perce...

Pasteuria penetrans isolate P-20 has been attributed as the cause of soil suppressiveness to peanut root-knot nematode in Florida. In this study, P. penetrans was transferred from a suppressive site to a new site and established by growing susceptible hosts to the peanut root-knot nematode during both summer and winter seasons. When two soil fumigants, 1,3-dichloropropene (1,3-D) and chloropicr...

Cortada, L., P. Manzano, F. J. Sorribas, C. Ornat, and S. Verdejo-Lucas. 2010. The resistance response of Solanum huaylasense accession LA1358 to Meloidogyne spp. Nematropica 40:31-40. Pathogenicity tests were performed to determine resistance in the wild tomato Solanum huaylasense to four populations of Meloidogyne spp. The S. huaylasense accession LA1358, the root-knot nematode resistant toma...

Resistance to the southern root-knot nematode, Meloidogyne incognita races 1 and 3, has been identified, incorporated, and deployed into commercial cultivars of tobacco, Nicotiana tabacum. Cultivars with resistance to other economically important root-knot nematode species attacking tobacco, M. arenaria, M. hapla, M. javanica, and other host-specific races of M. incognita, are not available in ...

This study sought to control the root-knot nematode (RKN) Meloidogyne incognita using benign organo-chemicals. Second-stage juveniles (J2) of RKN were exposed to dilutions (1.0%, 0.5%, 0.2%, and 0.1%) of acetic acid (AA), lactic acid (LA), and their mixtures (MX). The nematode bodies were disrupted severely and moderately by vacuolations in 0.5% of MX and single organic acids, respectively, sug...

Management of Meloidogyne incognita (root-knot nematode) in cotton in the United States was substantially affected by the decision to stop production of aldicarb by its principle manufacturer in 2011. The remaining commercially available tools to manage M. incognita included soil fumigation, nematicide seed treatments, postemergence nematicide application, and cultivars partially resistant to M...

Root-knot nematode is one of the significant plant-parasitic nematodes in cucumber (Cucumis sativus L.). Considering its destructive potential, studies were carried out on effect organic amendments and their integration with chemicals upon root-knot pots (2016–17) infested field (2017–18), at research farm Punjab Agricultural University, Ludhiana, Punjab. Among amendments, mustard cake treatmen...
