Journal ArticleDOI

David W. Ragsdale,Brian P. McCornack,Robert C. Venette,Bruce D Potter,Ian V MacRae,Erin W. Hodgson,Matthew E. O'Neal,K. D. Johnson,R. J. O'Neil,Christina D. DiFonzo,T. E. Hunt,Phillip A. Glogoza,Eileen M. Cullen +12 more
TL;DR: The ET developed here is strongly supported through soybean growth stage R5, which provides a 7-d lead time before aphid populations are expected to exceed the economic injury level (EIL) and exposes a larger portion of the soybean aphid population to selection by insecticides, which could lead to development of insecticide resistance.
Journal ArticleDOI
Biology of the Soybean Aphid, Aphis glycines (Hemiptera: Aphididae) in the United States
TL;DR: Though at present management is primarily through broad-spectrum insecticides, biological control has a significant impact on soybean aphid population growth, and aphid-resistant soybean varieties are becoming increasingly available.
Journal ArticleDOI
Management Recommendations for Soybean Aphid (Hemiptera: Aphididae) in the United States
TL;DR: A summary of integrated pest management tactics for soybean aphid are discussed, including cultural, genetic, economic, and chemical controls, which will reduce overall production costs and minimize negative environmental effects such as human exposure, and mortality of beneficial insects and other animals.
Journal ArticleDOI
Probability of Cost-Effective Management of Soybean Aphid (Hemiptera: Aphididae) in North America
Kevin D. Johnson,Matthew E. O'Neal,David W. Ragsdale,Christina D. DiFonzo,Scott M. Swinton,Philip M. Dixon,Bruce D Potter,Erin W. Hodgson,Alejandro C. Costamagna +8 more
TL;DR: It is confirmed that a single insecticide application can enhance the profitability of soybean production at risk of a soybean aphid outbreak if used within an IPM based system.
Journal ArticleDOI
Drought impact on crop production and the soil environment: 2012 experiences from Iowa
Mahdi Al-Kaisi,Roger W. Elmore,Jose Guzman,Mark Hanna,Chad E. Hart,Matthew J. Helmers,Erin W. Hodgson,Andrew W. Lenssen,Antonio P. Mallarino,Alison E. Robertson,John E. Sawyer +10 more
TL;DR: The 2012 drought created unfavorable soil conditions for plant development and growth and changes in soil structure in many areas in the Midwest as mentioned in this paper, such as increased fracturing, crusting, and deterioration of soil structure and aggregation.
