Dry Down Decisions — Choosing a Harvest Aid for Faba Beans
August 25, 2015
By now you’ve learned to determine when to desiccate faba beans, and perhaps you are gearing up to go ahead. Now the all-important next question: what to spray?
According to Robyne Bowness, pulse research scientist with Alberta Agriculture and Forestry, there are currently only two options for drying-down faba beans: diquat (a desiccant) and glyphosate (a herbicide). Both chemicals come with their pros and cons, from water needed to seed viability. Bowness recommends producers weigh their options carefully, recognizing the purpose of the spray application, the timing, and the end use of their crop.
