We invite Wisconsin farmers and agronomists to collect waterhemp seeds this fall from their row crop production fields and submit them to UW-Madison for herbicide resistance screenings.

In 2017 the Xtend soybean technology was completely launched in the United States. We invite stakeholders to take our short survey intended to investigate perceptions on dicamba use in Xtend soybeans in Wisconsin.

At the beginning of July, the weather finally became conducive for POST-emergence herbicide applications in southern Wisconsin, including for dicamba application in Xtend (dicamba-tolerant) soybeans. Typically, injury from micro-rates of dicamba in susceptible crops tends to show at 10-14 days after the incident. We ask Wisconsin stakeholders to provide estimates of dicamba-injured acres to help scientists and decision-makers understand the status of dicamba injury during the 2018 growing season (information will be kept confidential).

Excessive and constant rainfall through the season thus far across southern Wisconsin has challenged timely herbicide applications. Though the application window is getting shorter, wait for the right opportunity to spray and adjust herbicide program if necessary (don’t spray under marginal conditions).

One of the first steps to prevent further spread of a noxious weed species, is to properly recognize it. Herein are presented images that may help stakeholders identify this troublesome weed and differentiate it from other common Pigweed species.

At our on-farm research site in Chippewa county, WI, waterhemp emergence has been occurring for approximately two weeks. At our site in Grant county, WI, we noticed the first waterhemp seedlings today (06/04/2018). These plants will start growing rapidly as we move into the warmer portion of the growing season.

With recent rains and warmer temperatures, fall-planted cereal rye is growing rapidly and it’s important to have a termination plan in mind prior to crop establishment.

Spring has finally arrived in Wisconsin and so has the planting season. Before getting your soybeans in the ground, make sure you have plans for your PRE-emergence herbicide program.

PRE-emergence herbicides are the foundation for good weed control in corn and soybeans, particularly with the spread of herbicide-resistant weeds. The use of some PRE-emergence herbicides is limited to certain regions or counties in Wisconsin. Prior to selecting a herbicide for your weed management program, make sure the same is approved for use in your region.

See the results of the Wisconsin Cropping Systems Weed Science survey. The objective of the survey was to evaluate the main weed species and management strategies adopted in Wisconsin cropping systems, particularly in corn and soybeans.
