Infection Behavior and Overwintering Survival of Foliar Nematodes, Aphelenchoides fragariae, on Hosta.
We studied the pathogenicity and overwintering survival of the foliar nematode, Aphelenchoides fragariae, infecting Hosta spp. Nematodes applied to either lower or upper sides of noninjured and injured hosta leaves were able to infect and produce typical symptoms on nine cultivars. Leaves of only four cultivars (Borschi, Fragrant Blue, Patomic Pride, and Olive Bailey Langdon) showed no symptoms...
متن کاملInterrelationship of Aphelenchoides fragariae and Xanthomonas begoniae on Rieger begonia.
Disease complexes initiated by plantparasitic nematodes and bacteria on aerial plant parts are relatively uncommon. Interactions involving Aphelenchoides ritzemabosi (Schwartz) Steiner & Buhrer, Anguina tritici (Steinbuch) Chitwood, and Ditylenchus dipsaci (Kiihn) Filipjev with species of Corynebacterium are known (1, 3, 8). Ditylenchus dipsaci also is reported to interact with Erwinia rhaponti...
متن کاملEffectiveness of a Hot Water Drench for the Control of Foliar Nematodes Aphelenchoides fragariae in Floriculture.
Effectiveness of a hot water drench for the control of Aphelenchoides fragariae infesting hosta (Hosta sp.) and ferns (Matteuccia pensylvanica) was studied. Drenching with hot water at 70 degrees C and 90 degrees C in October reduced (P < 0.05) A. fragariae in the soil but not in the leaves relative to the control (25 degrees C) 300 days after treatment (DAT). Plants drenched with 90 degrees C ...
متن کاملResistance of rice cultivars to white tip disease caused by Aphelenchoides
Aphelenchoides besseyi is a seed-borne plant parasitic nematode and is widely distributed in most rice growing areas. Application of resistant cultivars requires the identification of resistance source, which can then be included in breeding programs to improve the local rice cultivars. Fourteen Iranian rice genotypes including improved and local varieties were evaluated for resistance to A. be...
متن کاملInduction of Glutaredoxin Expression in Response to Desiccation Stress in the Foliar Nematode Aphelenchoides fragariae.
Desiccation tolerance plays an important role in the overwinter survival of the foliar nematode Aphelenchoides fragariae. Survival rates of A. fragariae were compared with those of the anhydrobiotic soil-dwelling nematode Aphelenchus avenae after desiccation (90% RH), cold (4°C) and osmotic (500 mM sucrose) stress treatments. A. fragariae formed aggregates during desiccation and showed higher s...
