It’s been over one hundred years since the powered rotary hoe was invented, and we may not be done with it quite yet. Research by Agriculture and Agri-Food Canada is being conducted around using the rotary hoe as a weed management tool in pulses, inspired in combination by previous work in the organic sector and the growing concern over herbicide resistance.
In this Pulse School episode, Eric Johnson, weed biologist and officer-in-charge with Agriculture and Agri-Food Canada, walks us through trials looking at incorporating granular ethalfluralin with a rotary hoe in the fall and using the rotary hoe as a weed management tool after seeding pulses. The rotary hoe is hoped to provide some incorporation of the ethalfluralin and will likely show less disturbance than a harrow, while overcoming the problems of excess trash. Johnson explains timing, optimum speeds, the implications this research may have and how the trials look so far.
