Damon Smith, UW-Extension Field Crop Plant Pathologist, talks about in-season fungicide use on alfalfa crops. Typically in a 30-day cutting interval, like that used in dairy production in Wisconsin, foliar diseases cause minimal damage. Coupled with the heightened risk of fungicide resistance development toward these modern fungicides, application of fungicide on alfalfa for dairy production is not recommended unless heavy disease pressure is observed.
