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 was evaluated in 2005 at the Northern Research Farm. Soybeans sprayed at stage R3 yielded 4.3 bushels 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.
