Managing Corn Rootworm Populations in Illinois: Considerations for 2018

  • March 8, 2018

  • Nick Seiter

 
Authors: Nick Seiter, Joe Spencer, and Kelly Estes
Rootworm management is a yearly consideration for most corn producers in central and northern Illinois. Western corn rootworm (Fig. 1) is the primary pest species throughout most of the state, but areas in northern IL can experience pest pressure from the northern corn rootworm (Fig. 2) as well. Adult population densities have been low in recent years compared with historical averages, although they did creep up a bit in 2017.…

Adjacent and Neighboring: How Far is That?

  • February 19, 2018

  • Aaron Hager

An article posted to the Bulletin last November outlined several changes made by the United States Environmental Protection Agency to the labels of XtendiMax, Engenia, and FeXapan.  The intent of these label amendments is to reduce sensitive plant species exposure to dicamba primarily through physical movement (i.e., drift during the application or particle movement during temperature inversions) and via dicamba residues dislodged from application equipment.  Those in Illinois who have completed the required dicamba training being conducted by registrant personnel likely heard repeatedly that preventing off-target movement during the application is solely and completely the responsibility of the applicator. …

Test Your Integrated Weed Management Knowledge!

  • February 6, 2018

  • Aaron Hager

Test your knowledge of integrated weed management (IWM) with this short quiz (https://www.surveymonkey.com/r/SD9RT6R). The quiz is anonymous, and the answers will be revealed at the end.
Effective long-term weed management requires integrating multiple effective techniques, as opposed to relying solely on one or two tactics. This is particularly true as troublesome herbicide-resistant weeds continue to develop and spread throughout the US. Diversifying weed management tactics, preventing the introduction of new weeds, and varying herbicide modes of action reduces the spread and establishment of resistant weeds.…

Calling Central Illinois Landowners with CP42

  • January 16, 2018

  • Maddy Kangas

 
Agriculture comprises nearly half of terrestrial global landscapes posing a number of challenges to native pollinators. However, the Conservation Reserve Program’s CP42 Pollinator Habitat program aims to mitigate these challenges by providing pollen and nectar resources for pollinators where they may be lacking.
With funding from the National Institute of Food and Agriculture (NIFA) and the North Central IPM Center, Madeline Kangas, a University of Illinois graduate student in the Department of Natural Resources and Environmental Sciences,…

One More Call for Soybean Production Information

  • January 12, 2018

  • Emerson Nafziger

A number of times over the past 30 months I’ve asked Illinois soybean producers for help in gathering field-level information on soybean fields to feed into a study, led by the University of Nebraska and funded by the North Central Soybean Research Program, looking at weather, soil, and management effects soybean yield over the Corn Belt.
The last growing season from which we are collecting information is 2017, so this is probably the last time I’ll ask.…

Precautions for Dicamba Use in Xtend Soybeans

  • November 27, 2017

  • Aaron Hager

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