Foliar Fungicide Treatments in Alfalfa


  • Determine value of foliar fungicide applications on mature alfalfa using field-scale trials.
  • Assess effect of fungicide application on yield, crude protein, digestibility and relative feed quality.

Study Description


Plot Layout:      Fields were split into treated and untreated blocks.
Replicates: 1 per location. Multiple wind-rows were used as treatment subsamples
Locations: 3 in central MI (see map below)
Factors: Foliar fungicide: Treated, untreated
  • Locations were sprayed with 6 oz/acre of Headline® fungicide 7 days after first cutting.
  • Data were collected on the second cutting harvest.


Map: Northeast Agronomoy Research


  • Results shown are averaged across locations.
  • Alfalfa stands were similar among locations.
  • Treated and untreated yields and quality components were similar at 2 of the 3 locations.
  • 1 location seeded in fall 2009 had a modest yield, protein, relative feed quality and %NDFd gain with foliar fungicide compared to untreated (data not shown).
  • This study will be repeated in 2013.

2012 data are based on average of all comparisons made in 3 locations through November 30, 2012. Multi-year and multi-location is a better predictor of future performance. Do not use these or any other data from a limited number of trials as a significant factor in product selection. Product responses are variable and subject to a variety of environmental, disease, and pest pressures. Individual results may vary. All products are trademarks of their manufacturers.
