Home Wheat Streak Mosaic Wheat streak mosaic virus is transmitted by the leaf curl mite.
Symptoms generally appear in the spring and become more severe as the season progresses.
Infected plants usually are stunted with discontinuous yellow streaks in the leaves. Microscopic, light green, cigar-shaped leaf curl miles usually can be found on leaves of infected plants. Wheat streak mosaic has been found only in isolated instances in northeast Arkansas. The disease generally is associated with the presence of volunteer wheat between harvest in June and emergence of the next crop in the fall. Volunteer wheat is an ideal host for both mite and virus.
