In climates where cool, moist conditions occur regularly, Karnal bunt is difficult to control. Fungicidal seed treatments provide control of seed-borne inoculum but do not eradicate the disease when applied to infected seed because the spores are well protected by the pericarp, or fruit coat. The movement of farm machinery and soil from contaminated fields is also being restricted. County composite samples are also being tested in the other 32 wheat producing counties of the state. A nationwide survey is also being conducted.
