Abstract: Downy mildew (DM) continues to be a major threat to pearl millet production in Africa and Asia. In India, heavy losses due to DM caused the withdrawal of several new genotypes. Considerable progress has been made in the development of screening techniques and identification and utilization of host-plant resistance. The systemic fungicide metalaxyl has been highly effective in controlling infection by soil-, seed-, and airborne inoculum. Although variability in the patho1445gen, within and between continents has been demonstrated, sources of stable resistance have been identified. Cultivation of disease-resistant varieties, use of metalaxyl if resistance fails, coupled with roguing of infected plants are recommended for long-term control. Identification of durable resistance, basic genetic studies on the host and pathogen, and studies on the resistance mechanism(s) are suggested as research priorities.
