One of the most common wheat disease problems in Kansas this year was
barley yellow dwarf. Some questions have arisen about this. One of the
questions is why was barley yellow dwarf has been so widespread when there didn’t
seem to be many bird cherry-oat aphids or greenbugs reported. This is a good
question, but I don’t think anyone has any answers. The only explanation is
that the aphids and greenbugs had to have been present in the regions where
barley yellow dwarf has occurred, just at low population levels. Those are the
two primary vectors of barley yellow dwarf on wheat. It doesn’t take a very
high population of aphids to introduce and spread the virus. |

Periods of early-season flooding or soil saturation can sometimes cause immediate problems for small corn plants, said Kraig Roozeboom, K-State Research and Extension crop production specialist.

Overnight temperatures dropped below freezing in parts of
western and northern Kansas
on the mornings of May 15-16. This is unusually late for freezing temperatures
to occur in any part of the state. In low areas of the fields, temperatures
will typically be lower than the officially recorded temperatures, and this
will be where freeze damage will be most likely.

The extreme heat, at or near 100 degrees, on May 8-10 has
resulted “gaping florets” on wheat that was in the flowering stage when the
heat occurred. The photo below was taken in Geary County
on May 13, and the symptoms can still be seen in many fields.
