Soybean aphids continue to dominate the insect problems in Iowa's field crops during the last part of July. Five questions were recently posed to the extension field agronomists across the state regarding the current soybean aphid situation. These questions were: (1) When did spraying start for soybean aphids?; (2) Spraying is occurring in what counties?; (3) If spraying has not occurred, what are the population levels at across your area?; (4) Are Harmonia/multicolored Asian lady beetles occurring in the same fields as the aphids?; and (5) Any other observations that you want to provide would be appreciated.
