Growing Industrial Hemp in Conventional Agricultural Fields? Don’t forget to check what herbicides were sprayed last year(s) and adjust your spray program moving forward if Industrial Hemp will become part of your crop rotation. Remember, the label is the law.

With the onset of the spray season and concerns regarding waterhemp and other troublesome weed species, farmers and consultants are further diversifying and including herbicides with soil residual activity in their weed control programs. This past week we received several questions regarding herbicide tank mixtures. Herein we try to address the questions.

Spring has arrived rather quickly in Wisconsin and the planting season is right around the corner (or perhaps it has already started for some growers). Before getting their soybeans in the ground, farmers should make sure they have solid weed management plans for the growing season, particularly if waterhemp is present in their operations.

With warmer temperatures and rainfall in the forecast, fall-planted cereal rye will start growing rapidly; thus, it’s important to have a termination plan in mind prior to crop establishment.

UW-Madison Extension invites farmers and crop advisors to attend one of the Wisconsin Regional Waterhemp Workshops to be held in four locations across the state in March of 2019.

Check the results of twenty-three corn and soybean herbicide evaluation research trials conducted by the WiscWeeds Program during the 2018 growing season.

On October 31, 2018 the United States Environmental Protection Agency announced their decision to extend the registration of the dicamba products Engenia, Fexapan, and Xtendimax for use in dicamba-tolerant crops (Xtend technology) through December 20, 2020; however, additional label changes were made. In this post, I (try to) address the new 57-foot omnidirectional buffer requirement to protect federally listed threatened and endangered species and critical habitat in specific US counties.

20 unique cases (weed species by herbicide site of action) of herbicide resistance have been confirmed in Wisconsin, including 13 weed species with evolved resistance to one or more herbicide sites of action. Herein we share the current state of documented herbicide resistance cases in Wisconsin crop production.
