Summary and Implications
The best probability of achieving an economic response to a foliar fungicide application in alfalfa production is to first crop. Other than that, we need to be more selective of our opportunities for an economic return based on scouting, yield potential, environmental conditions and alfalfa forage value. To apply fungicides to alfalfa without consideration for yield potential of individual cuttings or environments favorable to disease development would not follow proper stewardship of pesticide use nor result in maximizing
