Slow growing aphid populations
For the week of July 27, 2009, Drs. Erin Hodgson and Matt O'Neal review reports and data on soybean aphid populations from Iowa and the midwest. Although large populations can be found, many growers are reporting low populations with less than 50% of the plants infested with aphids. Also, Erin discusses reports of soybean defoliation by insect pests that are not aphids.
