Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
Maize plants collected in three geographically distinct regions of South Africa were found to be doubly infected with maize dwarf mosaic (MDMV) and cucumber mosaic virus (CMV). A mixed infection of these two viruses could be maintained in maize plants grown under laboratory conditions. The …

Maize dwarf mosaic virus: purification, some physical properties, and yield of virus from several corn hybrids
To better understand the nature of maize dwarf mosaic virus (MDMV) and its interaction with susceptible and resistant corn hybrids, the purification of MDMV and its physical properties were re-evaluated and a rapid assay procedure was developed. The virus was purified by chloroform clarification …

Maize Dwarf Mosaic Virus in Zea Mays L.: Inheritance of Resistance, Yield Loss, Serology, and Seed Transmission
… effect on sweet corn yield of inoculation with maize dwarf mosaic virus (MDMV) at the three-leaf, eight-leaf, or just prior to silking was examined. Early infection delayed maturity, reduced yield and plant height. Little difference was found between the late inoculation and the inoculated …

Studies on sweet corn: Stewart's wilt forecasting, the effect of maize dwarf mosaic on foliar diseases, and herbicide sensitivity
… reactions to Pantoea stewartii, the effect of maize dwarf mosaic (MDM) on eight foliar diseases, and the effect of hybrid CYP genotype on sweet corn yield following postemergence applications of mesotrione or nicosulfuron. Stewart’s disease can be forecasted using the Stevens, Stevens-Boewe, or …

Inheritance of reactions to gray leaf spot and maize dwarf mosaic virus in maize and their associations with physiological traits
… zeae-maydis, can be a yield-limiting factor in maize where continuous minimum tillage practices are followed. Commercial corn hybrids were evaluated for response to gray leaf spot for seven years at two Virginia locations (Shenandoah and Wythe Counties) and one year at a third location in …

Cloning and characterization of the 3' terminal regions of RNA from select strains of maize dwarf mosaic virus and sugarcane mosaic virus
… cDNAs derived from the 3$\sp\prime$ terminus of maize dwarf mosaic virus, strain A (MDMV-A), maize dwarf mosaic virus, strain B (MDMV-B), maize dwarf mosaic virus, strain KS1 (MDMV-KS1), maize dwarf mosaic virus, strain O (MDMV-O), and sugarcane mosaic virus strain H have been cloned as a first …

The effect of varying mixtures of soybean and cereals on the landing rates of aphid vectors and spread of soybean mosaic virus (SMV) and maize dwarf mosaic virus (MDMV)
… transmitted plant viruses such as soybean mosaic virus (SMV) and maize dwarf mosaic virus (MDMV), and also on the landing rates of the aphid vectors that transmit them. The uniqueness of this study is that it gives an insight as to how the same aphids spread two foregut-borne …

A study of filamentous viruses in maize and smallgrains
The occurrence of maize dwarf mosaic virus (MDMV) in field grown maize was investigated. For this purpose, maize showing mosiac symptoms was collected from different maize growing areas in South Africa by Prof. M.B. von Wechmar. These samples from Transvaal, Orange Free State and Natal were then …

Effect of postemergence johnsongrass control on MCDV and MDMV incidence and severity in field corn
… expression were consistent with those caused by maize chlorotic dwarfvirus (MCDV) and maize dwarf mosaic virus (MDMV) infection of com. It was hypothesized that postemergence johnsongrass control increased the incidence and severity of MCDV and MDMV in virus-susceptible corn hybrids due to …

Investigation of Methods and Mechanisms of Control of Italian Ryegrass (Lolium multiflorum) in Corn (Zea mays) and Small Grains and of the Effects of Johnsongrass (Sorghum halepense) Control on Virus Diseases in Glyphosate-Tolerant Corn
… to investigate the incidence and severity of maize chlorotic dwarf virus (MCDV) and maize dwarf mosaic virus (MDMV) in response to POST johnsongrass control in two corn hybrids. Recent observations have indicated a lack of virus-tolerance in glyphosate-tolerant corn hybrids in Virginia. The …
