Northern Research and Demonstration Farm
BASF Corporation agronomists have reported that applications of Headline fungicide improve general soybean plant health and ultimately improve yields. The response to Headline fungicide has been evaluated at the Northern Research Farm for the past three years. In 2005, a single soybean variety sprayed at stage R3 yielded 4.3 bushels/acre more than the check plots. In 2006, the experiment was expanded to evaluate the yield responses of four varieties treated at stage R3. Additionally, one variety was evaluated for responses to treatments applied at stage R1 and stage R3. The experiment was repeated in 2007 using the same varieties and application timings as the 2006 experiment.
