Formulation
Water dispersible granule containing 600 g/kg cymoxanil.

Rainfastness
Rainfall or irrigation within 2 hours after application may reduce effectiveness.

DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

Restrictions
Allow a minimum of 7 days between applications.
Do not allow packs to become wet during storage.
Do not keep opened packs from one season to another.
Only apply OPTION in tank‐mixture with other fungicides.

Crops
OPTION can be used on all varieties of early and maincrop potatoes. On crops grown for processing consult your processor before use.

Timings
Timing of spray applications should take into account the prevalence of the disease in the area and if conditions support disease spread. The first spray should be applied as soon as there is a risk of blight infection or an official warning has been issued. In the absence of a warning, spraying should begin just before the crop meets along the rows. Applications should be repeated at 10‐14 day intervals depending on the prevalence of the disease and favourable conditions for infection. A 7 day spray interval may be used under exceptional circumstances e.g. blight risk is already high and rain is forecast at the time of the next 10 day spray is due. High risk situations include conditions of rapid growth, irrigated crops, areas of intensive potato growing, particularly blight‐sensitive varieties, when further warnings are issued, or when active blight is in the area. The longer interval is recommended under dry conditions. Irrigation of crops increases the risk of blight and crops should always be sprayed with OPTION as soon as possible after irrigation subject to the minimum spray interval. Irrigated crops should normally be sprayed at 10 day intervals.

Volume and application
Apply OPTION in 150 litres of water per hectare using a MEDIUM quality spray (as defined by BCPC). Higher water volumes may be used in thick or dense crops to improve coverage.

Dose
Apply OPTION at 0.15 kg/ha in tank‐mixture another product recommended for control of potato blight containing a fungicide from a different cross resistance group and is applied at a dose that will give robust control. All other requirements and restrictions on the partner product label(s) should be adhered to.

Resistance
When fungicides with the same mode of action are used repeatedly over several years in the same field, naturally occurring less sensitive strains may survive, propagate and become dominant in that field. It is therefore advised that wherever possible spray programmes should include fungicides with differing modes of action. Please refer to UKFungicide Resistance Action Group guidelines for further details.

Mixing
Spraying equipment should be thoroughly cleaned before spraying. OPTION mixes easily with water and should be added directly to the spray tank during filling. Wash out container and add washings to the spray tank. Continue agitation until spraying is complete.
