DIRECTIONS FOR USE
Asana is a fungicide with protectant, systemic and curative properties for use in winter and spring wheat, winter and spring barley, oats, rye and triticale.
 
Restrictions/Warnings
Avoid spray drift on to neighbouring crops.
This product may cause damage to broad-leaved plant species.
Wash equipment thoroughly after use.
 
Resistance Management
Asana contains kresoxim-methyl a member of the QoI cross resistance group. Asana 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. Asana meets this requirement as it contains epoxiconazole and fenpropimorph. To ensure the effectiveness of the epoxiconazole and fenpropimorph components as partners, Asana should always be applied at the full recommended rate.
Strains of wheat and barley mildew resistant to QoI‘s are common in the UK. Control of wheat powdery mildew can only be relied upon from the triazole component. Where specific control of wheat mildew is required this should be achieved through a programme of measures, including products with recommendations for control of mildew that contain different active substances used in mixture or sequence.
Asana 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 adviser, and visit the FRAG-UK website.
Use Asana 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.
Failure to follow resistance management action may result in reduced levels of disease control.
 
Crops
Asana is a fungicide for use in winter and spring wheat, winter and spring barley, oats, rye and triticale.
Time of Application
Apply Asana at the start of foliar disease attack. A maximum of two applications can be made up to and including flowering half way in winter and spring wheat, rye and triticale and up to and including emergence of ear just complete in winter and spring barley and oats.
For optimum effect against eyespot with Asana 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 Asana 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.
 
Rate of Application
Apply 1 litre Asana in 200 litres of water per hectare. Increase the water volume where the crop is dense.
 
Mixing and Spraying
Apply as a MEDIUM spray as defined by BCPC.
Half fill the spray tank with clean water and start the agitation. SHAKE THE CONTAINER WELL before use and pour in the required amount of product. Rinse any empty containers thoroughly and add rinsings to the spray tank. Add the remainder of the water and continue agitation until spraying is completed.
When tank mixes are to be used, each product should be added separately to the spray tank.
