Flowering Delay in Flue-cured Tobacco Infected with Meloidogyne Species.
Some forage grasses such as Great Basin wild ryegrass and Nordan standard crested wheatgrass are economically important because of their adaptation to grazing and environmental stress. These tests show that these forage grasses are hosts of M. chitwoodi. As reported for other Meloidogyne species (7), infection by M. chitwoodi may increase host sensitivity to drought by obliterating, compressing...
متن کاملInterrelationships of Meloidogyne Species with Flue-cured Tobacco.
Microplot and field experiments were conducted to determine relationships of population densities of Meloidogyne spp. to performance of flue-cured tobacco. A 3-yr microplot study of these interactions involved varying initial nematode numbers (P(i)).and use of ethoprop to re-establish ranges of nematode densities. Field experiments included various nematicides at different locations. Regression...
متن کاملVentriculitis due to infection with Rhizopus arrhizus
A 52-year-old heart-lung transplant patient presented to the emergency department with acute onset of neurologic symptoms. MRI showed ballooning of the left ventricle, midline shift and contrast enhancement in the anterior horn of the left ventricle. Ventricle neuroendoscopy revealed whitish, floccose aerial structures within the left ventricle. Brain biopsy cultures grew Rhizopus arrhizus. The...
متن کاملDevelopment of Selected Tobacco Cyst Nematode Isolates on Resistant and Susceptible Cultivars of Flue-cured Tobacco.
Tobacco cyst nematode (Globodera tabacum solanacearum) isolates were collected from 11 locations in Virginia, 3 in North Carolina, and 1 in Maryland. Isolates from each location were maintained and increased on flue-cured tobacco, Nicotiana tabacum cv K326. Plants of flue-cured tobacco cultivars K326 (susceptible) and NC567 (resistant) were each inoculated with 6,000 G. t. solanacearum eggs/pla...
متن کاملEffects of Tobacco Cyst Nematode on Growth of Flue-cured Tobacco.
The effects of infection by tobacco cyst nematode (Globodera tabacum solanacearum) on growth of flue-cured tobacco cultivars NC 567 (resistant) and K 326 (susceptible) were evaluated in the field in 1993 and 1994. Infection by G. t. solanacearum suppressed number of leaves, plant height, and fresh weight of leaves and feeder roots. Correlations between weekly egg densities of G. t. solanacearum...
