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 کاملRoot-knot Nematode Management in Dryland Taro with Tropical Cover Crops.
Twenty-two cover crops were evaluated for their ability to reduce damage by root-knot nematode, Meloidogyne javanica, to taro, Colocastia esculenta, in a tropical cropping system. Cover crops were grown and incorporated into the soil before taro was planted. Barley, greenpanic, glycine, marigold, sesame, sunn hemp, and sorghum x sudangrass DeKalb ST6E were poor or nonhosts to the nematode as me...
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 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 کاملAttacking Cancer at Its Root
This year the Lasker DeBakey Clinical Research Award will be shared by Brian Druker, Nicholas Lydon, and Charles Sawyers for their development of a targeted molecular therapy for treating chronic myeloid leukemia. Their work demonstrated the ability of drugs directed against cancer-causing oncogenes to turn a rapidly fatal malignancy into a manageable chronic disease.
