Fungicide technology options are emerging to help growers address the predicament of residual versus application timing.

Acuron GT outperforms and outyields any other post-emergence-plus-residual corn herbicide. How? It contains the unique active ingredient bicyclopyrone, which has been proven to deliver enhanced control of yield-robbing weeds and longer-lasting residual in glyphosate-tolerant corn.

The bicyclopyrone component of Acuron GT, in combination with mesotrione and its other active ingredients, helps provide enhanced control of yield-robbing weeds. And due to its longer-lasting residual control, it’s the only post-emergence corn herbicide that will deliver more bushels per acre than any other post-emergence-plus-residual corn herbicide. Across 16 head-to-head replicated trials, Acuron GT outyielded other post-emergence-plus-residual herbicides by an average of 8 bu/A.1
