Pulse School: A Long-Term Plan for the Control of Cleavers


Does your farm have the cleavers?

In this episode of the Pulse School, Ken Sapsford, research assistant at the University of Saskatchewan, explains issues surrounding the abundance of cleavers across the prairies. With the shift towards no-till farming practices, cleavers, which were once considered a summer annual, are now overwintering, particularly in the presence of good snow cover. Besides being in the five to eight whorl stage in spring, some of these cleavers are also Group 2 resistant. The problem will only become increasingly severe without management, and Sapsford explains the need to find alternative herbicides or risk losing pulse acres.

A timely interview. One of the most abundant weeds on our farm, and increasing despite a robust control program.
