Resistance Management
Opera contains pyraclostrobin, a member of the QoI cross resistance group. Opera should be used preventatively and should not be relied on for its curative potential.
When curative activity is needed apply QoI fungicides in mixture with a suitable dose of a curative fungicide from a different cross-resistance group. Opera meets this requirement as it contains epoxiconazole. To ensure the effectiveness of the epoxiconazole component as a partner, Opera should always be applied at the full recommended rate.
Opera contains epoxiconazole, a DMI fungicide. Resistance to some DMI fungicides has been identified in Septoria leaf blotch (Mycosphaerella graminicola) which may seriously affect the performance of some products. For further advice on resistance management in DMIs contact your agronomist or specialist advisor, and visit the FRAG-UK website.
Use Opera as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action. You must not apply more than two foliar applications of QoI containing products to any cereal crop.
There is a significant risk of widespread resistance occurring in Septoria tritici
populations in Ireland. Failure to follow resistance management action may result in reduced levels of disease control.
