Corn (Zea mays) - High Plains Disease
Cause The virus that causes this disease is also referred to as wheat mosaic virus, maize red stripe virus, high plains tenui virus or high plains virus. This virus is transmitted by the wheat curl mite (Aceria tosichella), the same vector that transmits wheat streak mosaic virus and both viruses have been detected in symptomatic plants. Corn, barley, yellow and green foxtail, rye, and witch grass may be sources of the HPV.
Symptoms Infected leaves exhibit a mosaic pattern and chlorotic spots. Co-infection with wheat streak mosaic virus results in plants that are mottled, chlorotic, severely stunted, and may die. Mottling and a yellow mosaic pattern in parallel, discontinuous streaks develop on leaves.
Cultural control
- Avoid late seeding.
- Control grassy weeds and volunteer wheat on which the vectors or virus may persist.
