Chemical Control of Field Horsetail
Published online by Cambridge University Press: 12 June 2017
Abstract
In the Peace River region, vegetative shoots of field horsetail, Equisetum arvense L., emerge from June 1 to July 1, and reach full growth about July 16. All herbicides studied were most effective applied July 16 to 30. Amitrole (3–amino–1,2,4–triazole) at 8 lb/A at this time gave 96% stand reduction the next year. For selective killing in barley, MCPA (2–methyl–4–chlorophenoxyacetic acid) at 4 to 8 oz/A killed 100% of the top growth in the year of application and gave 50 to 65% stand reduction the next year. Other herbicides tried were less effective.
