Effect of Entomopathogenic Nematodes on Mesocriconema xenoplax Populations in Peach and Pecan.
The effect of Steinernema riobrave and Heterorhabditis bacteriophora on population density of Mesocriconema xenoplax in peach was studied in the greenhouse. Twenty-one days after adding 112 M. xenoplax adults and juveniles/1,500 cm(3) soil to the soil surface of each pot, 50 infective juveniles/cm(2) soil surface of either S. riobrave or H. bacteriophora were applied. Another entomopathogenic n...
متن کاملBiological control of the phytoparasitic nematode Mesocriconema xenoplax on peach trees.
Seven fluorescent Pseudomonas spp. capable of inhibiting reproduction of Mesocriconema xenoplax have been isolated from soil sites that suppress both nematode multiplication and Peach Tree Short Life (PTSL). One of these seven strains, Pseudomonas sp. BG33R, inhibits M. xenoplax multiplication in vivo and egg hatch in vitro. Mesocriconema xenoplax populations on peach seedlings inoculated with ...
متن کاملAssociation of Macroposthonia xenoplax and Scutellonema brachyurum with the Peach Tree Short Life Syndrome.
High populations of both Scutellonema brachyurum and Macroposthonia xenoplax were detected in the root zones of peach trees growing at sites where peach tree short life occurred. Both nematodes responded to changes in tree health, with the highest numbers detected under the most vigorous trees; both populations declined as tree vigor declined. Few of either species were detected 6 months after ...
متن کاملHost Status of Three Transgenic Plum Lines to Mesocriconema xenoplax
The expression of gastrodianin antifungal protein (GAFP) in a form of its VNF isoform increases tolerance to Phytophthora root rot (Phytophthora cinnamomi) and the root-knot nematode (Meloidogyne incognita) in transgenic plum lines. However, nothing is known about the potential of the GAFP lectin to confer disease resistance to the ring nematode, Mesocriconema xenoplax, in plum. Three transgeni...
متن کاملImpact of Meloidogyne incognita on the Incidence of Peach Tree Short Life in the Presence of Criconemella xenoplax.
The relationship between Cricenemella xenoplax alone and in combination with Meloidogyne incognitaon the incidence of peach tree short life disease was studied in field microplots during 1989-96. The presence of M. incognita suppressed the population density of C. xenoplax on Lovell peach. Tree trunk diameter was significantly reduced in the presence of both nematode species prior to 1993. Soil...
