| In response to the introduction and rapid spread of soybean aphid as a major new invasive pest of soybean in North America, farmers who attended winter crop meetings in four states in North Central US were surveyed about their treatment of and knowledge about soybean aphids for crop years 2004, 2005, and 2006. Thirteen percent, 84%, and 35% of the farmers indicated they had treated for soybean aphid in 2004, 2005, and 2006, respectively. The average of the soybean acreage treated in each year was 50%, 87%, and 81%, respectively. Overall, the farmers showed a good understanding of soybean aphids and their impact on soybeans. Over 80% knew soybean aphids could repopulate and cause yield damage after an insecticide treatment. Seventy-five percent knew aphids... |

| In response to the introduction and rapid spread of soybean aphid, farmers in the Upper Midwest were surveyed about their treatment of and knowledge about soybean aphids for crop years 2004, 2005, 2006, and 2007. Overall, the farmers showed a fairly good understanding of soybean aphids and their impact on soybeans. Over 80% said soybean aphids could be treated and repopulate in the same crop year. For 2004-2006, at least 75% of the farmers said aphids damaged their soybeans by sucking sap. However this percentage dropped to 59% for 2007 with a greater percentage pointing at a combination of damage methods. This lower percentage for 2007 may be due to a broader, randomly selected sample of farmers who received the surveys by mail versus farmers who attended... |
