Pearl Millet Diseases
Viral Diseases

Maize Dwarf Mosaic Virus (MDMV)

Symptoms: Infected plants express mosaic and mild stunting.

Pathogen and disease characteristics: This potyvirus is generally transmitted by aphids (nonpersistently) or mechanically. Pearl millet is susceptible to "A" and "B" strains of MDMV. Symptom expression is not temperature sensitive. There appears to be strain specificity for some of the different hosts.

Host range: Pearl millet, maize, sorghum, johnsongrass, sudangrass, sand lovegrass, indiangrass, foxtail, barnyardgrass, large crabgrass, downy bromegrass, goosegrass, wild cane, sugarcane, teosinte, foxtail millet, plumegrass, napiergrass, Chrysopogon montanus Trin., finger millet (Eleusine coracana Garten.), rice (Oryza sativa L.), Panicum miliaceum L., P. miliare Lamk., Paspalum scrobiculatum L., Themeda quadrivalvis O. Kuntze, Urochloa mosambicensis (Hackel) Dandy, U. stolonifera (Goosens) Chippind.

Geographic distribution: "Widespread."

Nomenclature discrepancies: Alternative disease names: Sugarcane mosaic (this may be a different virus; see Krstic et al. 1995), grass mosaic, bajra mosaic.

Seed transmission: Transmission by seed in pearl millet has not been demonstrated. Very low frequency observed in maize.

Primary citations: Seth et al. 1972b, Rishi et al. 1973, Shurtleff 1980, Jensen et al. 1983.
