متن کاملManagement Options for Control of a Stunt and Needle Nematode in Southern Forest Nurseries
Crop rotation and fallow are management options that can be used to control plant parasitic nematodes in forest tree nurseries. Before these options can be put into practice, it is important to determine the host range and survivability under fallow of the parasitic nematode to be controlled. The results of host range tests on a needle nematode (Longidorus spp.) and a stunt nematode (Tylenchorh...
متن کاملStunt 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 کاملPLANT-INSECT INTERACTIONS Relative Suitability of Virginia Pine and Loblolly Pine as Host Species for Dendroctonus frontalis (Coleoptera: Scolytidae)
Dendroctonus frontalis Zimmerman is a major disturbance agent in American pine forests, but attack preferences for various host species, and their relative suitability for reproduction, are poorly known. We studied patterns of beetle attack and reproduction during an infestation of stands containing Virginia pine and loblolly pine. Nearly all Virginia pine were attacked and killed, whereas a th...
متن کاملEffects of Plant Growth-Promoting Rhizobacteria on Loblolly and Slash Pine Seedlings
Loblolly and slash pine seed were inoculated at sowing with 1 of 12 different strains of plant growth-promoting rhizobacteria (PGPR) in the greenhouse. Time to germination and seedling densities were determined at 21 days, and seedling biomass was measured at 12 wk after sowing. All bacterial strains significantly increased the speed of seedling emergence over nontreated pine seed. By 12 wk, ho...
