Target Fungicide Applications to Receptive Hybrids

The yield potential of a bag of seed has many factors that contribute to the overall result. In addition to seed, fertilizer and herbicides, fungicides are another tool that can help you optimize the yield potential of your corn crop.  
 
Research from the 2015 Answer Plot® Trials showed that response to fungicide scores pinpoint yield advantages from fungicide applications.
 
Finding #1
2015 Answer Plot® trials* found that a hybrid with a high RTF score and one with a moderate RTF score generated 9.69 bu/A and 8.17 bu/A more respectively than a hybrid with a low RTF score.
 
Conclusion
RTF scores accurately predict the effectiveness of fungicide applications on a hybrid-by-hybrid basis.
 
Finding #2
National results from the 2015 Answer Plot® Program show an overall 11.5 bu/A average yield response to fungicide applications over untreated corn. This represents 93 percent of the 32 participating Answer Plot® Program locations demonstrating a positive response to fungicide.
 
Conclusion
Fungicide applications can increase yield in corn across a range of maturities (in this case, 90 days to 115 days).
 
The RTF score provides you with a plan for in-season management by understanding which hybrids benefit the most from protection against fungal diseases and rust. Understanding the genetic response to fungicide treatments helps you determine where fungicides can increase yield potential and where they will be economically beneficial.
