What We Observed Across the 2026 Plots.
Patterns in the harvested results so far. They describe what happened in these plots — you’re the judge of how they fit your farm.
01Fungicide/insecticide plots yielded more on average at Danforth.Corn +10.0, soybeans +6.9 and the Stine plot +7.0 bu/ac — fungicide/insecticide vs. non-treated plot averages, one pair of plots each.
02Products didn’t respond alike.Corn responses ran from −10.7 to +26.0 bu/ac; soybeans from −8.1 to +17.1. Products may differ in how they respond to management practices — we’ll keep evaluating this locally.
03Later corn showed the larger responses.Every Danforth hybrid at 112 days RM and later yielded more with fungicide/insecticide. Those hybrids were also planted together, so maturity and position in the field can’t be separated here.
04One plot’s ranking didn’t predict another’s.26 hybrids were in both the Danforth non-treated plot and Piper City. Their orders barely matched: 647-09VT2 ranked 23rd at Danforth and 1st at Piper City; 644-64VT2 ranked 24th at Danforth and 3rd at Piper City; 8427V ranked 4th at Danforth and 25th at Piper City. That’s why we test in more than one place.
05The same soybean can respond differently in two plots.37EJ20: −3.8 in the soybean plot, +12.9 in the Stine plot; 31EJ82: +14.6 in the soybean plot, −2.9 in the Stine plot; 28EJ82: +17.1 in the soybean plot, +4.0 in the Stine plot (fungicide/insecticide minus non-treated, bu/ac).
06Peking varieties ran ahead of PI88788 in every soybean plot.On average +4.0 points of plot average across the four plots (page 22). The Peking group is smaller and earlier, so this shows where varieties landed, not why.
Research notes
Locations. 8 product plots in Cabery, Chenoa, Danforth and Piper City. Fungicide/insecticide, seed-treatment and tillage comparisons are from the Danforth Research Farm.
Data. Plot weights and moisture from the 2026 plot reports and plot form; field trials from John Deere harvest data and weigh-wagon scale weights. RM and SCN source from the AgTech 2027 product reference.
Yields. Adjusted to standard moisture and harvested row length. Ranks are within each plot.
Foliar fungicide/insecticide. Revytek fungicide (EPA Reg. No. 7969-406) + bifenthrin insecticide, applied together July 15, 2026.
Plot design. Each product was grown once per plot. No formal statistical tests are reported.
Economics. $4.55/bu corn and $12.62/bu soybeans are book assumptions; $35/ac covers product and application.
