The present study reveals antimicrobial potentials and phytochemical analysis of A. javanica and L. ustitatissimum. Phytochemical analysis indicated that the tested plants contained a substantial amount of flavonoids, terpenoids and steroids while saponins and tannins were absent in L. ustitatissimum, however, tannins were present in A. javanica. L. ustitatissimum contained maximum total phenol...

Several cover crops with potential for use in tropical and subtropical regions were assessed for susceptibility to three common species of root-knot nematode, Meloidogyne arenaria, M. incognita, and M. javanica. Crops were selected based on potential use as organic amendments in anaerobic soil disinfestation (ASD) applications. Nematode juvenile (J2) numbers in soil and roots, egg production, a...

The discovery of Meloidogyne mayaguensis is confirmed in Florida; this is the first report for the continental United States. Meloidogyne mayaguensis is a virulent species that can reproduce on host cultivars bred for nematode resistance. The perineal patterns of M. mayaguensis isolates from Florida show morphological variability and often are similar to M. incognita. Useful morphological chara...

culture filtrates (cf) of two species of the nematophagous fungi, arthrobotrys oligospora and arthrobotrys conoidesat three concentrations (25%, 50% and 100%) of stock, were tested on the mortality of second stage juveniles (j2) and egg hatching rate of meloidogyne incognita and meloidogyne javanica. results showed that the percent juvenile mortality was directly proportional to concentration o...

El subproducto de la industria vitivinícola (SIV) es rico en compuestos bioactivos, incluidos los fenólicos. Dado que nematodos del nudo raíz son suprimidos por fenólicos, enmienda suelo con SIV puede controlar estos patógenos. Evaluamos el efecto manejo Meloidogyne javanica plantas tomate invernadero. En primer estudio, macetas se enmendó 0, 5, 10, 15, 20, 25 o 30 g kg. Las dosis crecientes in...

Advance inoculation of the tomato cv. Celebrity or the pyrethrum clone 223 with host-incompatible Meloidogyne incognita or M. javanica elicited induced resistance to host-compatible M. hapla in pot and field experiments. Induced resistance increased with the length of the time between inoculations and with the population density of the induction inoculum. Optimum interval before challenge inocu...
