Why is kochia resistant to multiple herbicide groups? After all, it is not one factor, but several different aspects of plant growth, reproduction, and spread that are difficult to control and cause herbicide resistance. I found that it is easier to do.
In this episode of Wheat School, Dr. Charles Geddes, Agriculture and Agri-Food Canada Research Fellow in Lethbridge, talks about kochia’s range expansion, how kochia is adapting to new areas, and how weather patterns are driving its expansion. Let me explain how we are promoting this.
He also details how specific growth traits have allowed the species to evolve resistance to five different modes of action, four of which are found in biotypes on the Canadian prairie. Masu. Geddes said kochia populations have shown resistance to groups 2, 4, 9 and 14, and so far group 5 resistance has been seen outside of Canada.
What can we do about this aggressive tumbleweed? Complex problems require complex solutions. See below for more information on that discussion.
