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...

Even though oats (Avena spp.) have the capacity to produce numerous compounds with potential act antagonistically against plant pathogens, studies on genotypic effect of this crop focusing their nematicidal activity are limited. The objective study was verify aqueous extracts prepared biomass oat genotypes, hatching second-stage juveniles root-knot nematodes (Meloidogyne javanica and Meloidogyn...

Nematodes are very diverse and could be free-living or plant parasite species. Amongst the existing categories, most aggressive ones root lesion nematode (Pratylenchus spp.), root-knot (Meloidogyne cyst (Globodera spp.). These categories affect over 2000 susceptible crop species causing varying yield losses, reaching 100% under heavy infestations in potatoes. The common hosts include tomato (So...

Dentre os biomas brasileiros, o Cerrado é segundo em extensão territorial e diversidade de espécies vegetais animais. A biodiversidade do tem sido estudada no que tange a sua flora fauna, carecendo dados microorganismos representantes da microfauna, exemplo dos nematoides galhas radiculares. Meloidogyne spp. são endoparasitas sedentários plantas. presença solo áreas com vegetação nativa cerrado...

Pasteuria penetrans is a mycelial, endospore-forming, bacterial parasite that has shown great potential as a biological control agent of root-knot nematodes. Considerable progress has been made during the last 10 years in understanding its biology and importance as an agent capable of effectively suppressing root-knot nematodes in field soil. The objective of this review is to summarize the cur...
