New ways to beat weeds

GROWING PROBLEM: Waterhemp populations in more Midwest fields are exhibiting multiple resistance to herbicides of several chemical families.
ILF webinar will feature ways to use nonchemical tactics to manage herbicide-resistant weeds.

Are you looking for better, more effective ways to manage tough-to-control weeds? Be sure to tune in to the Iowa Learning Farms webinar Sustainable Weed Management Solutions for Iowa Corn and Soybeans at noon Oct. 21. The presentation will discuss ways to integrate and use nonchemical tactics to help manage herbicide-resistant seed banks.

Weed populations that develop resistance to certain herbicides are an increasing problem in many Iowa fields. “Herbicide resistance is a threat to the sustainability and profitability of corn and soybean production,” says Prashant Jha, associate professor and Extension weed specialist at ISU.

Nonchemical weed control

During the webinar, Jha will explain new integrated weed management strategies and how to incorporate them into your current weed management plans. These strategies focus on using reduced herbicide inputs with the goal of achieving long-term profitability and sustainability for Iowa corn and soybean production.

The nonchemical tactics explained and featured in the webinar include:

  • cover crops
  • reduced row spacing for corn and soybeans
  • new harvest weed seed control technologies

Jha’s research focuses on improving the understanding of weed biology and ecology to develop effective, integrated weed management strategies to be used in corn and soybean production systems of farmers in Iowa and the Midwest.
