Domark fungicide from Valent and Isagro is now registered by the EPA for use on corn.
Domark is a triazole chemistry with both systemic and contact activity. The company reports Domark has preventive and curative activity and is effective against a broad range of diseases in soybeans and corn, including leaf spots, rusts and leaf blights in corn.
Gerald Holmes, Valent field market development specialist, believes this alternative mode of action will be an important tool in growers' resistance management toolboxes. "Resistance management is a top-of-mind issue for many corn growers who are limited to mostly strobilurin products," Holmes said.
Since its introduction in the United States, Domark has been an effective tool in the control and prevention of major soybean diseases such as white mold, frogeye leafspot and purple seed stain — without causing green stems at harvest. Holmes said that results from corn trials conducted in the 2011 season indicate that Domark effectively controls yield-robbing diseases, which, in turn, protects yield potential.
