Competition of Transgenic Volunteer Corn with Soybean and the Effect on Western Corn Rootworm Emergence
- Paul T. Marquardt, C. Krupke, W. G. Johnson
- Biology
- 19 April 2012
Abstract Glyphosate-resistant (GR) volunteer corn has emerged as a problematic weed in corn∶soybean rotational systems, partly because of the rapid increase in adoption of corn hybrids that contain… Expand
Influence of Weed Management Practices and Crop Rotation on Glyphosate-Resistant Horseweed (Conyza canadensis) Population Dynamics and Crop Yield-Years III and IV
- Vince M. Davis, K. Gibson, T. Bauman, S. Weller, W. G. Johnson
- Biology
- 13 July 2009
Abstract Horseweed is an increasingly common and problematic weed in no-till soybean production in the eastern cornbelt due to the frequent occurrence of biotypes resistant to glyphosate. The… Expand
The impact of a fungicide and an insecticide on soybean growth, yield, and profitability
- R. S. Henry, W. G. Johnson, K. Wise
- Biology
- 1 December 2011
Abstract A growing number of soybean producers have begun to incorporate below threshold fungicide and insecticide treatments into their management programs in attempts to increase yield. The… Expand
Survey of Tillage Trends Following The Adoption of Glyphosate-Resistant Crops
Abstract A phone survey was administered to 1,195 growers in six states (Illinois, Indiana, Iowa, Mississippi, Nebraska, and North Carolina). The survey measured producers' crop history, perception… Expand

- 22 April 2016
Abstract Giant ragweed has been increasing as a major weed of row crops in the last 30 yr, but quantitative data regarding its pattern and mechanisms of spread in crop fields are lacking. To address… Expand
Dose Response of Glyphosate and Dicamba on Tomato (Lycopersicon esculentum) Injury
- G. Kruger, W. G. Johnson, D. Doohan, S. Weller
- Biology
- 2 July 2012
Abstract Field studies were conducted to determine the response of sublethal glyphosate and dicamba doses to processing tomato flowering loss and marketable yield. Dose–response studies for both… Expand

- Vince M. Davis, G. Kruger, J. Stachler, M. Loux, W. G. Johnson
- Biology
- 4 September 2009
Abstract Horseweed populations with mixtures of biotypes resistant to glyphosate and acetolactate synthase (ALS)–inhibiting herbicides as well as biotypes with multiple resistance to glyphosate +… Expand
Fall and Spring Preplant Herbicide Applications Influence Spring Emergence of Glyphosate-Resistant Horseweed (Conyza canadensis)
- Vince M. Davis, G. Kruger, B. Young, W. G. Johnson
- Biology
- 17 February 2010
Abstract Horseweed (Conyza canadensis) is a common weed in no-till crop production systems. It is problematic because of the frequent occurrence of biotypes resistant to glyphosate and acetolactate… Expand
