Mild, seasonable temperatures have profoundly influenced crop development and insect populations in the past few weeks.

A marked increase in alfalfa weevil populations is one of the most noteworthy events that can be attributed to recent favorable spring weather conditions, as well as an unusually early start to the first flight of European corn borer moths. Relatively light rainshowers brought much-needed moisture to most of the state, but the amount was insufficient in the northwest where drought conditions have prevailed since last summer. Considerable strides were made in corn planting, which increased to 76% complete, jumping a remarkable 38 percentage points in just one week. Roughly 32% of the state’s soybean crop has been planted.
