Soybeans
Volume 60 Number 5 Date 05/21/2015 SOYBEAN APHID - Surveys for aphids in Rock and Sauk counties yielded negative results. Colonization of the earliest emerging soybeans could begin before the end of the month. BEAN LEAF BEETLE - Overwintered beetles have been found in only two of 75 alfalfa fields sampled this month. The first appearance of this insect was noted on May 11 in Sauk County. The very low number of beetles collected thus far suggests only a minor threat of soybean defoliation in early June. However, the estimated 10% of soybean acres that have emerged as of May 21 are at increased risk of infestation by overwintered adults and should be checked for evidence of beetle feeding. -- Krista Hamilton, DATCP Entomologist
