SOYBEAN APHID - Surveys conducted in La Crosse, Monroe, and Vernon counties were negative. The first soybean aphids of the growing season may begin appearing in fields by the first week of June.
BEAN LEAF BEETLE - A few soybean fields are showing 1-2% of plants with minor feeding caused by this defoliator. Damage is currently very light, but could become more severe as additional beetles migrate to emerging soybeans next month.
