The Biology of the Red and Green Morphs of the Tobacco Aphid, Myzus Persicae Nicotianae (Blackman) on Flue-Cured Tobacco
The tobacco aphid, Myzus persicae nicotianae is an economically important pest of tobacco. Damage is through direct injury by sucking sap of infested plants as well as reduction of the quality of the leaf by leaving honey-dew which encourages the subsequent growth of sooty-mould. In addition to this, aphids also transmit economically important virus diseases such as the bushy-top virus, the alf...
متن کاملEffect of Transplant Age, Tobacco Cultivar, Acibenzolar-S-Methyl, and Imidacloprid on Tomato Spotted Wilt Infection in Flue-Cured Tobacco
Tomato spotted wilt virus (TSWV; family: Bunyaviridae) remains a serious problem in flue-cured tobacco production in Georgia and other parts of the United States. Stand losses in recent years have averaged 30% across the state, with total losses in some fields. There are no commercially available TSWV-resistant cultivars and resistant transgenic tobacco lines that have the TSWV nucleoprotein ge...
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 کاملFlowering 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 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...
