Smartweed species have been reported as important weeds to manage in Midsouth rice acres. Acetolactate synthase (ALS)-inhibiting herbicides have become the go-to options for successfully managing these species postemergence in rice.
With support from the United Soybean Board, in 2019 and 2020 we conducted a screening of 212 waterhemp populations from 7 different states to characterize their abilities to withstand applications […]
Growers, crop consultants and extension educators interested in management of atrazine/glyphosate-resistant Palmer amaranth are encouraged to attend Nebraska Extension’s in-person, outdoor field day, supported by the Nebraska Corn Board, from […]
Judging from research tests and walking a few farmers’ fields many of the PRE applied herbicides in soybean and cotton played out about a week or so ago. Timing is […]
In our research more dicamba sensitive Palmer amaranth will often be dead or well on their way under good heat and moisture conditions in 7 days or so. Palmer that […]
With no new herbicide modes of action on the horizon, agrichemical companies are combing through the archives for options to battle herbicide-resistant weeds. Now, for Bayer Crop Science, that rummaging […]
Work continues on new herbicide resistance cases in waterhemp and fall panicum.
It’s déjà vu all over again. We have run this article every few years, and it seems like maybe the frequency is increasing as we deal with wet and cold […]
