Precautions for Dicamba use in Xtend Soybean

  • November 13, 2018

  • Aaron Hager

The extension weed science programs at The Ohio State University, Purdue University, and the University of Illinois recently collaborated to revise suggestions and precautions for use of dicamba in dicamba-resistant soybean.  The United States Environmental Protection Agency renewed labels of Xtendimax, Engenia, and FeXapan last October, and this updated extension weed science publication offers additional suggestions to help further reduce off-target dicamba movement.

Too wet to sample for SCN?

  • November 8, 2018

  • Nathan Kleczewski

Soybean Cyst Nematode is an extremely important, yield limiting pathogen of soybeans in Illinois, reducing yields an average of 1-3% across the state.  As I have written in earlier posts, sampling your fields every 3-5 years to assess SCN levels and HG types is the first step in managing this issue.  The best time to sample for SCN is after harvest in the Fall, and this can easily be added onto any samples you gather for soil nutrient testing. …

The harvest in 2018 has been marred by frequent rains that resulted in soybeans in portions of the state being left out longer than desired.  As expected, more attention to these unharvested beans resulted in more observations.  One common observation was the presence of various types of black growth on stems of senesced plants,…

  • Emerson Nafziger

With harvest winding down in most of Illinois after another year with high to very high yields, it’s time to review some basics of fall fertilization. Neither fertilizer nor grain prices are historically high, so there’s reason to be aware of costs while making sure to cover the nutrient basics.
Nitrogen
In a webinar on October 19 organized by the Illinois Fertilizer & Chemical Association, we looked at some of the nitrogen response data that have come in so far this fall and considered what this might mean in terms of fall N management.…
