Soybean Aphid Management in South Dakota with Foliar Applied Insecticdes, 2014: Table 1

The Soybean aphid, Aphis glycines Matsumura, can be a serious problem of soybean, Glycine max L., production in South Dakota. The economic threshold is 250 soybean aphids on 80% of plants sampled. When the threshold is reached it may warrant an insecticide treatment to prevent potential yield loss through early R5 soybean development stage. During the 2014 growing season, we conducted a field study near Brookings, South Dakota using foliar applied insecticides for control …
