Description
A carpet-covered roller was used to apply herbicides to control woody plant regrowth in established pastures in Saskatchewan, Canada. A 1.5% v/v solution of a 4:1 mixture of 2,4-D ((2,4-dichlorophenoxy) acetic acid]:picloram (4-amino-3,5,6-trichloropicolinic acid) controlled the above ground growth of several tree and shrub species fairly well, but regrowth from the roots or stem bases usually occurred the year after the year of treatment. Applying a 1.5% v/v solution of glyphosate [N-(phosphonomethyl) glycine] resulted in more individual plant death but less permanent damage to survivors than the treatment with 2,4-D: picloram. The machine worked fairly well but is probably best suited to treatment of small patches of brush at least one metre tall to minimize damage to the forage understory, and not more than two metres tall because of the physical obstruction to the passage of the machine by larger trees.
