SCN and Soybean Aphid Resistance Management Workshop

Thursday, August 17, 2017 - 8:30am to 4:15pm

The two most important pests that reduce soybean yield (nematodes and aphids) are evolving, becoming resistant to commonly used pest management tools. This workshop will provide research-based, sustainable pest management recommendations for the control of soybean cyst nematode and soybean aphid. Information provided will include updates on the status of resistant pest populations in Iowa and hands-on demonstrations of sampling and managing both pests.   

Soybean Aphid Numbers on the Rise

August 4, 2014

Since 2000, soybean aphid has been the primary soybean insect pest in Iowa. Infestations are sporadic and unpredictable, but this insect has the ability to cause significant yield loss during periods of optimal reproduction. Several notable infestations have been reported, particularly in north-central Iowa, this week, and therefore scouting to determine population densities is strongly encouraged. Fields that have a fairly uniform infestation with low densities (e.g., 50% of plants infested with an average of 40 aphids per plant) should be closely monitored in August.
