Headline is an effective fungicide for controlling Cercospora leafspot. It has also been promoted as a yield enhancer beyond its effect as a fungicide. Some farmers use Headline for this yield improvement on other crops, and a benefit has been found to Headline on sugarbeets in some research in other areas. Michigan Sugar Company has tested this claim for four years and Sugarbeet Advancement tested two locations for one year.
Methods:Michigan Sugar Company research compared Headline to Eminent, and other Strobilurin fungicides, for four years and to an untreated check two of the years. Cercospora was controlled with Super Tin and Topsin plus Penncozeb applications as needed. The treatments were applied as an extra application not needed to control Cercospora. Fungicides used the first three years
