Localized populations of these species found on headlands or field margins likely represent a new introduction. Populations that are distributed throughout fields are likely a sign that these species have gone undetected for more than one year.
Planting delays gave an incredible advantage for weeds in some fields in 2022, enabling weeds to germinate and emerge at the same time as crops in 2022. It is important that farmers do what they can to limit weed seed production and movement to help prevent weed infestations in the future.
Depending on the species, weeds spread with the help of wind, water or by other means, but human factors seem to be the best way to spread weeds from field to field, across a state, from state to state and even from one country to a different one.
In a new study from the University of Illinois, scientists document waterhemp’s resistance to yet another class of herbicides, known as Group 15s. The study provides the first documentation of a non-grass plant to be resistant to Group 15 herbicides.
California farmer Tom Barcellos discusses the challenges of strip-tilling in his unusual environment and how his Bigham strip-till bar and the Orthman 1tripr are able to overcome these hurdles. He'll detail his equipment setup as well as describe how extensive use of RTK GPS to ensure everything lines up with the strip.
