Maize Streak Virus (MSV): Understanding the Disease and Control Measures

Causes:
- MSV is caused by a virus transmitted by leafhoppers (Cicadulina spp.).
- It thrives in areas with warm temperatures and frequent leafhopper activity.

Symptoms:
- Pale yellow streaks on leaves running parallel to the leaf veins, leading to reduced photosynthesis.
- Stunted plants with poor cob development, significantly reducing yields.

Management Strategies:
- Resistant Varieties: Plant MSV-resistant maize varieties to minimize infection risks.
- Insect Control: Use integrated pest management (IPM) techniques, including insecticide applications, to control leafhopper populations.
- Field Hygiene: Remove volunteer maize and weeds that may harbor the virus or vector.
