Barnes County uses a variety of chemicals including Tordon, Curtail,
and Rodeo to treat Canada Thistle. Canada Thistle is a huge problem for
the residents of Barnes County. Because of this we decided to have a test
plot for different chemicals applied under different environmental conditions.
Chemicals tested were Tordon, 2-4, D, Redeem, Curtail, and Plateau. The
test plot is located on Fish and Wildlife land and therefore is comparable
to CRP acres in the county. The test plot was first sprayed in the summer
of 2001; part was also sprayed in the fall of 2001. Canada Thistle that
was left standing, clipped and burned was sprayed. There is a field day
planned for the summer of 2002, please watch for information here.
We have started insectaries with five different bio-control agents. Please stay in touch for more information as it becomes available.
