Soybean Gall Midge Adult Emergence Begins

Jun 23, 2022

By Ashley Dean and Erin Hodgson

This week, the first soybean gall midge adults (Photo 1) were collected in Iowa near Wall Lake in Sac County (Monday) and near Sutherland in O’Brien County (Thursday). This is similar to when soybean gall midge emergence was first detected in Iowa in 2021. The first Midwest report of soybean gall midge emergence in 2022 was on June 7 near Davey, Nebraska. You can keep up with soybean gall midge emergence at soybeangallmidge.org/. We will also send text updates on soybean gall midge activity in Iowa through the Iowa Pest Alert Network this summer.

Typically, plant injury is noticeable and larvae can be found feeding within stems a few weeks after adult emergence. Begin scouting for soybean gall midge larvae now, especially if plants are at least V2. Start scouting at the edge of soybean fields adjacent to fields that were infested last year or, if infestations were not noted last year, begin at the field edge near last year’s soybean. A black lesion is usually noticeable at the base of the plant (Photo 2). Look for white or orange larvae feeding inside soybean stems (Photo 3) by using your fingernail or a knife to split the stem. Early in the season, infestations might be noticeable if random plants are dead or wilting among otherwise healthy-looking plants (Photo 4). This becomes less obvious later in the season as the canopy closes.

Unfortunately, there are no known, effective management strategies to suppress larvae at this time. This summer, universities around the Midwest continue to monitor the distribution and evaluate potential management strategies.

Video: A chain harrow is a game changer

Utilizing a rotational grazing method on our farmstead with our sheep helps to let the pasture/paddocks rest. We also just invested in a chain harrow to allow us to drag the paddocks our sheep just left to break up and spread their manure around, dethatch thicker grass areas, and to rough up bare dirt areas to all for a better seed to soil contact if we overseed that paddock. This was our first time really using the chain harrow besides initially testing it out. We are very impressed with the work it did and how and area that was majority dirt, could be roughed up before reseeding.

Did you know we also operate a small business on the homestead. We make homemade, handcrafted soaps, shampoo bars, hair and beard products in addition to offering our pasture raised pork, lamb, and 100% raw honey. You can find out more about our products and ingredients by visiting our website at www.mimiandpoppysplace.com. There you can shop our products and sign up for our monthly newsletter that highlights a soap or ingredient, gives monthly updates about the homestead, and also lists the markets, festivals, and events we’ll be attending that month.
