Plot Size Makes a Difference
To solve this conundrum, Tedford, technical product lead for fungicides at Syngenta, conducted a number of trials from 2009 to 2013. His research uncovered a “borders and alley” effect, which showed that the larger gaps between corn rows in small plot trials make a big difference in the results.
“Small-plot trial work on fungicides provides very meaningful results in terms of efficacy against diseases and even yield benefits when disease pressure is high,” says Tedford. “However, when disease pressure is low, they misrepresent grower-relevant yield benefits from fungicides. In those incidences, the borders and alley effect can cause different yield results than what growers might expect in their fields.”
