These articles were written primarily for Illinois, Iowa and Indiana who all got hit as hard as we did, but have been getting hit constantly for the past 2 months. Regardless, I do believe that this article is appropriate for Wisconsin considering the past 48 hours.
If your crops are underwater, there is little you can do. You are probably looking for all of the information you can get, in an effort to make plans, in case re-planting is in your future. Some of the information here has been previously provided, but nevertheless, let’s do a re-run on replanting.
Purdue agronomist Bob Nielsen provides a summary of the impacts of floodwaters on young corn plants. He covers issue, such as time underwater, temperatures, impact on soil, post flood vigor, and potential diseases after flooding. . http://extension.entm.purdue.edu/pestcrop/2008/issue10/index.html
The June 2 issue of Iowa State’s Integrated Crop Management News is primarily focused on flooding issues. Addressed are replant options and getting rid of the damaged crop, saturated soils, impact of flooding on soybeans, and soybean replant decisions. http://www.extension.iastate.edu/CropNews/2008/Issues/20080602.htm
Missouri agronomist Laura Sweets addresses seed decay and seedling blight in the May 30 issue of the Integrated Pest and Crop Management newsletter. http://ppp.missouri.edu/newsletters/ipcm/archives/v18n9/v18n9.pdf
Ohio State University agronomist Peter Thomison provides an overview of ponding impacts in a newsletter for the Crop Observation and Recommendation Network. http://corn.osu.edu/index.php?setissueID=134
Purdue’s Neilsen offers an updated factsheet on the Effects of Flooding or Ponding on Young Corn. It provides similar suggestions previously cited, along with several related references. http://www.agry.purdue.edu/ext/corn/news/timeless/PondingYoungCorn.html
Peter Thomison at Ohio State University, writing in the current C.O.R. N. newsletter, offers several thoughts about patching in corn, where the stand is less than satisfactory. He covers timing relative to the first planting, replanting where emergence is uneven, and cultivation challenges. http://corn.osu.edu/index.php?setissueID=232
University of Illinois fertility specialist Fabian Fernandez, writing about nitrogen application challenges, suggests that questions should be answered whether nitrogen is really going to help a crop with a mediocre yield potential. He also addresses the impact of nitrogen in flooded soils. http://www.ipm.uiuc.edu/bulletin/article.php?id=952
Replanting decisions are accompanied by a need to decide on what to do about insecticides. University of Illinois entomologist Kevin Steffey addresses maximum rates and the possibility of switching insecticides, in his May 23rd newsletter. http://www.ipm.uiuc.edu/bulletin/article.php?id=938 |
