Soil borne plants are exhibiting a strong yellow mosaic commonly associated with low or poorly drained areas. Wheat spindle streak symptoms are expressed as small dashes or streaks with purpling of leaves. In addition, Wheat Streak Mosaic has had a couple of reports in central Kansas. The most recent was small wheat in Rush County that appeared to be infected late last fall from adjoining volunteer. Reports were in Cherokee county and incidence was recorded at nearly fifty per cent in one field where aphids were reported at moderate levels.
Aphids transmit the disease from plant to plant.
In monitoring of grain export samples since the first of the year, no important phytosanitary diseases were found.
