Talking Points

Recent interactions between the hosts and their guests.

S11 E11 - HRAC 2026 Update: Changes to the Herbicide Modes of Action Poster
Q: What happens to compounds removed from the poster?
Removed compounds stay in the HRAC master spreadsheet and the online lookup tools; they are not erased from the database and may reappear in future updates if warranted by new data or market conditions.
S11 E11 - HRAC 2026 Update: Changes to the Herbicide Modes of Action Poster
Q: How are additions to the poster decided and what happens when a new compound is added?
Decisions rely on the evidence strength and proximity to market; approved compounds are added to the poster and simultaneously linked to the master list and online tools, with the poster updated every two years while the online resources update in real time.
S11 E11 - HRAC 2026 Update: Changes to the Herbicide Modes of Action Poster
Q: Why is motive action classification important?
Because it serves as a guide for resistance management on rotating and mixing different modes of action for weed control, providing a framework aligned with herbicide labels to reduce resistance risk.
S11 E11 - HRAC 2026 Update: Changes to the Herbicide Modes of Action Poster
Q: What kind of information has to be generated in order to get a herbicide listed on HRAC materials?
Companies provide data on chemical structure, common name, molecular data, metabolic pathways, and specific mechanism or target, supported by mutagenesis, biochemical assays, and cross-resistance data, with peer-reviewed publications preferred to substantiate the mode of action, and additional information if published data are insufficient.
S11 E15 - Two States, One Challenge: The War on Weeds in Cotton
Q: What do you think about the split in Xtend versus Enlist versus other trait packages in your cotton areas?
In the area discussed, Xtend is predominant, with pockets of Enlist; label changes and regional adoption influence which program growers select, always balancing yield performance and tool availability.
