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...

Resistance of pepper species (Capsicum annuum, C. baccatum, C. chinense, C. chacoense, and C. frutescens), cultivars and accessions to the root-knot nematodes Meloidogyne incognita race 2 and M. javanica, and their graft compatibility with commercial pepper varieties as rootstocks were evaluated in growth chamber and greenhouse experiments. Most of the plants tested were highly resistant to M. ...

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...

Trichoderma harzianum strain ESALQ-1306 was assessed for its potential biological control against Meloidogyne incognita race 4 under in vitro and greenhouse conditions. In vitro, we noticed 64% of conidial attachment on eggs and second-stage juvenile immobilized by the fungus. In greenhouse, cucumber plants were treated with different concentrations of conidial suspensions before and after inoc...

Selection of detectable numbers of Mi-virulent root-knot nematodes has necessitated a greater understanding of nematode responses to new sources of resistance. During the course of this research, we compared the reproduction of four geographically distinct Mi-virulent root-knot nematode isolates on three resistant accessions of Lycopersicon peruvianum. Each accession carried a different resista...

The effects of a yard waste compost amendment and crop establishment on nematode populations and yields of suscep­ tible vegetable crops were determined in two tests in Florida in sites infested with the root-knot nematode, Meloidogyne incognita. Main plot treatments consisted of 269 mt/ha of a yard waste com­ post applied as a mulch, 269 mt/ha of the compost incorporated into the soil, and an ...
