Nematodes attacking cultivars of peach in north Carolina.
Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...
متن کاملProvisional Estimate of Crop Loss in Sugarcane Caused by Nematodes
Results of more than 130 field trials with nematicides, principallyaldicarb, weregroupedaccordingto the claycontent and parent material of the soil on which the trials were conducted. An estimate of loss in yield due to nematodes was obtained by extrapolating from the results of the field trials to the total area under sugarcane on each soil group. Crop loss per unit area was greatest on the Re...
متن کاملBurkholderia Tropicalis, a Potential Bacterial Inoculant to Control Nematodes and Improve Sugarcane Growth
The bacterial genus Burkholderia is abundant in the sugarcane rhizosphere. Literature states that some Burkholderia strains are nematode and fungal antagonists and/or plant growth promoters. Research was undertaken to obtain indigenous sugarcane-associated Burkholderia strains that possess these properties. Preliminary screening produced 13 isolates that are able to paralyse juveniles of Meloid...

15 صفحه اولCONTROL OF INSECT PESTS WITH ENTOMOPATHOGENIC NEMATODES I. Control of Weevils with Entomopathogenic Nematodes
Entomopathogenic nematodes in the genus Steinernema and Heterorhabditis have been successfully commercialized as biological control agents for a variety of curculionid species. Nematode-based products have been introduced for: 1) root weevils, Otiorhynchus spp. 2) billbugs, Sphenophorus spp. 3) the apopka weevil, Diaprepes abbreviatus, and 4) the citrus root weevil, Pachnaeus litus. Several oth...
