Effect of postemergence johnsongrass control on MCDV and MDMV incidence and severity in field corn
… 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 increased feeding by vectors of these viruses on treated corn. Field …

Cloning and characterization of the 3' terminal regions of RNA from select strains of maize dwarf mosaic virus and sugarcane mosaic virus
… 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 step in the creation of transgenic …

Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
… 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 possibility of synergism or of an interference mechanism between MDMV and CMV in dual infections …

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 …

Maize Dwarf Mosaic Virus in Zea Mays L.: Inheritance of Resistance, Yield Loss, Serology, and Seed Transmission
… 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 control.

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)
… 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 non-persistently transmitted viruses in the same cropping …

Maize dwarf mosaic virus: purification, some physical properties, and yield of virus from several corn hybrids
… 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 and …

Inheritance of reactions to gray leaf spot and maize dwarf mosaic virus in maize and their associations with physiological traits
… once established. Maize dwarf mosaic virus (MDMV) also limits maize production in some areas where johnsongrass (Sorghum halepense L.) is a problem. Resistance to MDMV was found to be mainly additive and highly heritable. However, a strong specific combining ability component was found, …

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
… 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 rapidity of virus disease development in corn resulting from …
