Stinkbug Mania

The stinkbug is not usually a pest we think about, but be on the lookout for these pests because by the time you see their injury, it could be too late.  Why?  We want to protect our seeds!

This pest is relatively new to the U.S. and is mainly an issue in the South and Eastern cornbelt;  however, they could be a concern in the Midwest.  A warm winter does not necessarily predict the invasion of the pest, but it can put fields at higher risk.  Fields that are late planted, have cool weather that delay maturity, or vulnerable to pests could also be at risk.  Heavy populations are possible and they are great hitchhikers.

There are many different kinds of stinkbugs and they can be pests of many different crops as well as fruits and vegetables.  They have round, oval bodies with a shield shaped triangle on their backs with 5 segmented antennae.  One stinkbug that we are especially worried about is the Brown Marmorated Stink Bug, which has white bands on it's antennae as well as other distinguishing characteristics. This pest arrived in the U.S. in 1998 and its populations are building.   As they get hungry, we fear they will move from orchards to corn and soybeans.

Stinkbugs have piercing and sucking mouth parts that can poke through husks or pods.  This causes seeds to be shriveled, blasted, or flat.  We especially worry about injury on soybeans.  Most insecticides are labeled for stinkbug control.  Adult stinkbugs can tolerate more insecticide, but younger stinkbugs, such as nymphs, are easier to kill.

Scout several areas (10) throughout the soybean field with a sweep net or visually, then average the number of stinkbugs that you find.  Populations will be higher at dusk or dawn.  If you see an average of 4 or more adults/nymphs after R2 growth stages or mid August, you may consider an insecticide treatment.  The threshold is lower for seed fields.

What the Heck is that Corn Disease?

Several weeks ago, Bryce Sandahl, our Account Manager near the Rockford, Illinois texted me a picture of a disease showing up on corn.  He thought it looked like gray leaf spot, but was not sure because we really had not had the right conditions for disease development.


When I looked at the lesion, it looked shiny, so I immediately thought bacteria.  We looked under the microscope and found bacterial oozing coming from the leaf tissue.  We did an ELISA quickstrip test to test for Goss's wilt (another common bacterial disease in corn) and it tested negative.

Back, in the old days, when I was at the U of I Plant Clinic, we would have assumed it was most likely Stewart's wilt by process of elimination.  But, with new diseases constantly emerging, such as Bacterial leaf streak, we need to be careful!  So, I sent a sample to the U of I Plant Clinic and they confirmed that it was Stewart's wilt by use of primers and sequencing!

Stewart's wilt was also a major threat to sweet corn!  It is vectored and spread by the corn flea beetle. After the recent mild winter, it is possible that  the corn flea beetle populations could be heavier this year.

There can be two stages of this disease:  seedling wilt phase, which affects susceptible young plants and the leaf blight phase, when infection takes place after tassel.  Remember that insecticides in seed treatments like PowerShield® help to control the corn flea beetle in young plants, so this helps to combat the seedling wilt phase of Stewart's wilt.

The main way to control this disease is resistance and if it is found today, the lesions will be small, watersoaked, following veins, with wavy margins (like the picture) and not extend much further than 2 to 3 cm from where the corn flea beetle fed. Before resistance in hybrid corn, the symptoms from Stewart's wilt were much more serious.

Fun Facts:  This disease was thought to be first described in the 1880's by the entomologist, T.J Burrill, who is famous for his work on Fireblight and helping to prove that plant diseases could be caused by bacteria.

Stewart's wilt held much economic importance throughout history because of quarantine restrictions, costs associated with breeding for resistance, and phytosanitary regulations within seed trade.

Lastly, this disease brought back many memories from my U of I college years when working as an undergraduate with Dr. White's corn plant pathology breeding crew.  If you were a short student worker, like me, you got the job of "clapping" the corn, during the seedling stage, with Stewart's wilt inoculum.   Later, these various corn lines were evaluated and rated after disease development.  If you were good, like me, you got to hold the clipboard for the grad student and take notes for them!

2017 Burrus Seed Summer Interns


Each summer, Burrus Seed hires a group of interns to assist our production, sales, and agronomy teams. We would like to recognize our outstanding 2017 interns for their help and dedication to the Burrus Seed team. This year's interns logged a lot of miles and hours helping our growers with all their seed needs.

While our goal is to expose our interns to all sides of the seed business, we do offer internship opportunities in three different areas of focus: Sales, Production, and Agronomy.

We are now accepting resumes for our 2018 summer internships, and will be attending several college career fairs across our footprint this fall. If you are interested in an internship with Burrus Seed, visit our website or email us at burrus.seed@burrusseed.com.

Sales Internships
Our sales interns work directly with our Account Managers, making sales calls and interacting with both customers and prospects. Our four sales interns collectively made over 380 calls to growers this summer.

Kevin Freel
Kevin is 21 years old from Fort Atkinson, Wisconsin. He will be a senior this fall at the University of Wisconsin-Platteville. Kevin is maintaining a 3.0 GPA, studying Agriculture Business with an emphasis in Commodity and Price Analysis. Kevin played 2 years for the Platteville Pioneer football team. This was Kevin's second summer interning with Burrus Seed in our Hughes territory, and he was excited to be back.

Katelyn Muhlenberg
Katelyn is from Aledo, Illinois and will begin her senior year at Western Illinois University this fall. She is pursuing a major in Agriculture Business because of her love for agriculture developed while growing up on her family's farm. "I heard about Burrus through past interns, and did my research before I attended WIU's agriculture career fair. Burrus stands out because the family communicates with you personally and isn't strictly business. They want to know about your personal life and do anything to help you have a better experience with the company."

Agronomy Internships
Our agronomy interns work directly with our team of agronomic experts, gaining behind the scenes experience with the planning and planting of research plots. In addition, they gain hands-on training walking farms to identify weed and pest issues, and discover solutions with our sales agronomists.

Griffin Greene
Griffin is from Concord, Illinois and attends the University of Illinois. He studies Agriculture Leadership Education with a goal to one day go into Ag sales, and will be a junior this fall. Griffin is the Vice President and Recruitment chair for the Alpha Gamma Rho fraternity. This marked Griffin's 8th summer working at Burrus. "I have worked in the seed fields until this summer where I have been working in the research department.  I have really enjoyed my new role this summer and have gained a vast amount of new knowledge I plan to use in the future."
