Stunt Nematode (Tylenchorhynchus claytoni) Impact on Southern Pine Seedlings and Response to a Field Test of Cover Crops
The stunt nematode, Tylenchorhynchus claytoni, was found to cause a reduction in root volume (cm) of loblolly pine at population densities equivalent of 125 nematodes/100 cm (6 in) soil and greater. The results of a host range test conducted in containers under controlled conditions determined that buckwheat cultivar (Fagopryum esculentum ‘Mancan’), velvetbean (Mucuna pruriens), Kobe lespedeza ...
متن کاملPathogenic Potential of Tylenchorhynchus dubius on Selected Turfgrass.
Tylenchorhynchus dubius was observed to feed on 'Toronto' creeping bentgrass and 'Merion' Kentucky bluegrass, and was a key participant in reducing the vegetative growth of both grass species. The severity of foliar and root macrosymptoms incited by T. dubius to 'Toronto' bentgrass was greater on plants grown at 16 C than on plants maintained at 21, 27 and 32 C. These parasitized plants exhibit...
متن کاملOccurrence of Brown Blight Caused by Waitea circinata var. zeae on Cool Season Turfgrass in Korea
In 2010, disease symptoms, including necrotic lesions on stems and leaves with circular yellow-brown or irregular brown color patches, were observed on cool-season turfgrass at golf courses (OHCC) and the Daegu University research farm in Gyeongbuk, Korea. We isolated the causal agent and identified it as Waitea circinata var. zeae by morphological characterization and molecular analysis. To th...
متن کاملSusceptibility of Japanese holly to Criconemoides xenoplax, Tylenchorhynchus claytoni, and certain other plant-parasitic nematodes.
Three cultivars of Ilex crenata: 'Helleri', 'Convexa', and 'Rotundifolia' were inoculated with either Criconemoides xenoplax, Helicotylenchus dihystera, Hoplolaimus galeatus, Trichodorus cltristiei, or Tylenchorhynchus claytoni at 0, 200 (low), or 2,000 (high) nematodes/ 15-cm diam pot. Plants were kept in the greenhouse 10 mo prior to transplanting into 2.25 m(2) field plots. Helleri was sever...
متن کاملDescriptions of Two New Species of Tylenchorhynchus Cobb, 1913 (Nematoda: Tylenchida), with Details on Morphology and Variation of T. claytoni.
Two new species of plant parasitic nematodes (Tylenchorhynchus quaidi n. sp. and T. tritici n. sp.) from Pakistan are described and illustrated. Tylenchorhynchus quaidi n. sp., from soil around roots of potato (Solanum tuberosum) from an experimental field of NNRC, Karachi, Pakistan, is distinguishable from other species by its peculiar sunken dome-shaped head. Although similar to T. goffarti, ...
