Recently Sip Cam Agro, the manufacturer of Eminent, provided detailed information on their new product. Eminent has a section 18 in North Dakota and Minnesota for control of Cercospora leafspot. Mode of Action. Eminent is a sterol inhibitor, in the same class of chemistry and with the same mode of action as Tilt and Folicur. This class of fungicide inhibits the growth of higher fungi by preventing C 14 demethylation, which is an essential step in ergosterol synthesis.
Ergosterol is an essential building block in the cell wall of higher fungi.
Eminent is locally systemic, i.e. it is taken up by the leaf and moves within the leaf. No spreader-sticker is required. The label states that Eminent should be applied at 14-21 day intervals. Data from Europe indicate that Eminent provides good control on a 21 day interval if disease pressure is light to moderate. However, Sip Cam is recommending a 14 day interval, as indicated below.
