Fungicides are often evaluated in small-plot trials that are effective for assessment of disease control, but not very effective for assessment of true potential yield benefit.

Summit Agro USA R&D Manager Dr. Eric Tedford co-authored an article published in the journal Crop Protection investigating this question of whether plot size has an effect on the yield benefit of foliar fungicides. 

The authors’ research found evidence to support the idea that larger plots are more reflective of yield benefits that growers might recognize from fungicides compared to smaller plots. This is important for growers to remember when assessing fungicide yield data as they choose crop protection solutions.
