Micronutrients for Soybean Production in the North Central Region
North Central Soybean Research Program and Iowa State University Extension, 2017

This publication is a resource for farmers and crop advisors of the North-Central region regarding micronutrient use in soybean production. Its purpose is to discuss issues and provide information on micronutrients requirements by soybean and factors that influence their utilization.

It includes a thorough discussion on the value of soil and plant tissue analyses to determine micronutrient needs.

Scouting for Soybean Stem Diseases
The most effective management of soybean stem diseases starts with proper identification.


Symptoms of soybean stem diseases typically appear in the mid to late reproductive stages of soybean. This publication includes diagnostic photos of sudden death syndrome, pod and stem blight, stem canker, white mold, charcoal rot, Phytophthora root and stem rot, seedling diseases and anthracnose (2016).

Pod and stem blight and Phomopsis seed decay

Pod and stem blight often damages maturing plants and can result in premature death. Phomopsis seed decay can greatly affect seed quality. Both diseases can occur when susceptible varieties are planted and there is greater than normal rainfall during the pod-filling growth stages (2015).

Stem canker


Stem Canker
Stem canker can be difficult to diagnose because the symptoms look similar to other soybean diseases. This publication includes a table comparing symptoms expression on roots, stems, and leaves for stem canker, brown stem rot, Fusarium wilt, Phytophthora stem rot, sudden death syndrome, tobacco streak virus, and white mold on soybean (2016).

Fungicide resistance FAQ


Fungicide Resistance in Field Crops FAQs

Resistant fungal strains, caused by naturally-occurring genetic mutations, are already present in the fungal population. Fungicide applications select for these resistant fungal mutants — the fungicides kill the fungicide-sensitive population and only the resistant mutants survive. Eventually, the population of the resistant fungal strains increases and replaces the sensitive fungal population (2016).




Soybean Stem Zone Lines

Soybean Stem Zone Lines

Zone lines on the interior of soybean stems are associated with Diaporthe fungi and not the fungus that causes charcoal rot, as previously thought. This bulletin provides a clearer picture of soybean stem diseases and helps with diagnosis of symptoms that result from infection by pathogens. (2016)

Scouting Phytophthora

Scouting for Phytophthora Root and Stem Rot in Soybean

Phytophthora sojae can infect the plant at any growth stage from seedling through maturity. Scouting for Phytophthora root and stem rot should be done following prolonged periods of rain when soil temperatures exceed 60°F. Finding patches of diseased plants in low-lying, poorly drained portions of fields is common. (2015)

Seedling Diseases

Soybean Seedling Diseases

Diagnosing seedling diseases in the field can be difficult since the symptoms of various seedling blights are very similar. This publication discusses the characteristics of the organisms that cause seedling diseases, describes injury symptoms that may appear similar to these diseases, and briefly addresses how to manage seedling diseases (2015).

Soybean Seed Treatments

Soybean Seed Treatments: Questions that Emerge When Soybean Plants Don’t.

Poor soybean stand establishment is frustrating, especially considering all the time and money spent on seed, planting, and maintaining fields.


This is particularly true when farmers have also invested in seed treatments designed to prevent crop loss due to seedling diseases. However, every product has limitations and may not always work the way it is intended. Conversely, a user may expect a product to work in a way in which it was not intended. In this publication, we answer some common questions that emerge when soybean plants don’t! (2016)



Soybean vein necrosis virus Soybean Vein Necrosis Virus
Soybean farmers should be aware of a new disease caused by soybean vein necrosis virus (SVNV). The virus has likely been in soybeans for some time, but was probably overlooked or misdiagnosed before recent detections. The disease has been detected across the United States (including many states in the North Central region) and in Ontario, Canada (2015).
