streak mosaic symptoms should start to show up with the warmer weather.
Look for stunted plants with mottled, streaked leaves. Don't confuse
the winter damage on the lower leaves with wheat streak. In the case
of wheat streak, all the leaves on the infected plant often show the
mottling. Many people were confusing wheat streak with winter/drought
symptoms earlier in the month. Wheat streak symptoms you see now were
likely the result of fall infections from the curl mite, so there
is little that can be done at this point. There is great temptation
to plant early in fall following rains. However, this increases the
chances of streak mosaic infection since the curl mites are more likely
to move or 'bridge' from volunteer wheat or corn to the new wheat
crop. Resist the temptation for early planting.
