Inhibition of Tea Root Lesion Nematode, Pratylenchus Loosi, by rhizospher bacteria
Root-lesion disease, which is caused by Pratylenchus loosi , is one of the most important diseases currently impacting Iran tea plantations. This disease causes great economic crop impacts. Northern provinces, which supply much of Iran’s tea production, have been especially hard impact by root-lesion disease.The purpose of this study was to biological control the nematodes as one of the main se...
متن کاملEctoparasitic feeding behaviour of the root lesion nematode, Pratylenchus penetrans, on root hairs of different host plants
The feeding behaviour of Pratylenchus penetrans on root hairs was observed using video-enhanced contrast microscopy. The behayiouk could be separated into phases of probing, ce11 penetration by the stylet, salivation and food ingestion for brief and extended ,periods. &ter cell penetration, a small “ salivation zone ” was formed around the stylet tip. No feeding tubes were observed. The root ha...
متن کاملCulture of the Root-Lesion Nematode Pratylenchus vulnus on Carrot Disks.
O'Bannon and Taylor reported that carrot disks on 1% agar were suitable for culturing Pratylenchus brachyurus (4). We found that they are suitable also for Pratylenchus vulnus, and easier to prepare than the alfalfa tissue we have used in the past (3). Our observations on carrot disks during the last 3 years may be useful to others. Initially, many of the carrot disks rotted, and a variety of s...
متن کاملResponse of Peach Seedlings to Infection by the Root Lesion Nematode Pratylenchus penetrans under Controlled Conditions.
Twenty-one open pollinated populations of peach rootstock seedlings were evaluated for their response to infection by the root lesion nematode, Pratylenchus penetrans, over a period of 98 days. Nematode-infected peach seedling populations were shorter in plant height and had less shoot weight but more dry root weight than nematode-free controls. Rootstock differences were demonstrated for nemat...
متن کاملGenetic Characterization of Resistance in Wheat to the Root-Lesion Nematode Pratylenchus Thornei
The root-lesion nematodes Pratylenchus neglectus and P. thornei are economically damaging pathogens of wheat in the Pacific Northwest (PNW). Growing resistant and tolerant varieties is the best approach to minimize yield loss. All PNW wheat varieties were found to be susceptible. Crosses were made between the PNW-adapted varieties (Alpowa Louise, Otis) and the Australian wheat GS50a with resist...
