Opus Star is a systemic fungicide for use in winter wheat, spring wheat, winter barley, spring barley, triticale and rye.

1. Restrictions/Warnings
This product may cause damage to broad-leaved plant species. Avoid spray drift on to neighbouring crops. Wash equipment thoroughly after use.

2. Disease Control
Opus Star is a systemic fungicide with protectant and curative properties for the control of a range of diseases in winter and spring wheat, winter and spring barley, rye and triticale
2.2 Resistance Use Opus Star 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.

3. Crop specific information
3.1 Crops
Opus Star is a systemic fungicide with protectant and curative properties for use in winter wheat, spring wheat, winter barley, spring barley, triticale and rye.
3.2 Time of Application
Apply Opus Star at the start of foliar disease attack. Applications can be made up to and including emergence of ear just complete in winter and spring wheat, rye, triticale and winter and spring barley. For optimum effect against eyespot with Opus Star apply between the leaf sheaths erect and second node detectable stages of the crop. For protection against Fusarium ear blight and sooty mould on the ears of winter and spring wheat, apply Opus Star during ear emergence. For control of Septoria tritici and Septoria nodorum, treatment should normally be made after the third node detectable stage when disease is present and when weather favouring disease development has occurred. A follow-up treatment may be necessary if conditions continue to favour disease development.
3.3 Rate of Application
Apply 1.8 litres Opus Star in 150 to 300 litres of water per hectare.
Opus Star must be applied with CA 259. The minimum application rate of CA 259 is 0.5 l/ha.

The following does not form part of the product label under S.I. No. 83 of 2003:
With many products there is a general risk of resistance developing to the active ingredients. For this reason a change in activity cannot be ruled out. It is generally impossible to predict with certainty how resistance may develop because there are so many crop and use connected ways of influencing this. We therefore have to exclude liability for damage or loss attributable to any such resistance that may develop. To help minimise any loss in activity the BASF recommended rate should in all events be adhered to. Numerous, particularly regional or regionally attributable, factors can influence the activity of the product. Examples include weather and soil conditions, crop plant varieties, crop rotation, treatment times, application amounts, admixture with other products, appearance of organisms resistant to active ingredients and spraying techniques. Under particular conditions a change in activity or damage to plants cannot be ruled out. The manufacturer or supplier is therefore unable to accept any liability in such circumstances. All goods supplied by us are of high grade and we believe them to be suitable, but as we cannot exercise control over their mixing or use or the weather conditions during and after application, which may affect the performance of the material, all conditions and warranties, statutory or otherwise, as to the quality or fitness for any purpose of our goods are excluded and no responsibility will be accepted by us for any damage or injury whatsoever arising from their storage, handling, application or use; but nothing should be deemed to exclude or restrict any liability upon us which cannot be excluded or restricted under the provisions of the Unfair Contract Terms Act 1977 or any similar applicable law.
