Stink Bugs on Soybean

Stink Bugs on Soybean in the North Central Region
North Central Soybean Research Program, USDA, and land-grant universities in the north-central region, 2017

A new field guide is available to assist soybean growers and scouts identify and monitor stink bugs and their damage in the North Central region. Although stink bugs can be many different colors and variable sizes , adult stink bugs have a classic shield-shaped body that helps with identification.


 In addition, two beneficial stink bugs may be encountered on soybean: the Spinedshouldered stink bug and the Twospotted stink bug. These stink bugs are predators of crop pests and should not be included in calculations for monitoring and treatment.

Pod and stem blight and Phomopsis seed decay

Crop Protection Network/NCSRP, 2015.


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.

Fungicide resistance FAQ



Fungicide Resistance in Field Crops FAQs
Crop Protection Network, 2016

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.




Scouting Phytophthora


Scouting for Phytophthora Root and Stem Rot in Soybean
Crop Protection Network, 2015

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.

Seedling Diseases

Soybean Seedling Diseases

Crop Protection Network, 2015


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 vein necrosis virus


Soybean Vein Necrosis Virus
Crop Protection Network/NCSRP, 2015

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.
