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.
Rudis is recommended for control of a wide range of diseases on cabbage, Brussels sprouts, broccoli/calabrese, cauliflower, carrot, swede, turnip, parsnip and leeks.
For best disease control and yield benefit Rudis should be applied at an early stage of disease development, before infection spreads to new crop growth.

CABBAGE, BRIUSSELS SPROUTS, BROCCOLI/CALABRESE, CAULIFLOWER
Diseases: Dark leaf spot (Alternaria brassicae & Alternaria brassicicola), ring spot (Mycosphaerella brassicicola) and powdery mildew (Erysiphe cruciferarum), (Pyrenopeziza brassicae) and Phoma leaf spot (Phoma lingam). 
Rate: 0.4 L/ha

LEEKS
Diseases: Leek rust (Puccinia allii) and purple blotch (Alternaria porri), Cladosporium allii (leaf blotch) and Stemphylium botryosum.
Rate: 0.4L/ha

PARSNIP,SWEDE,TURNIP
Diseases: leaf blight (Alternaria dauci), Sclerotinia rot (Sclerotinia sclerotiorum), powdery mildew (Erysiphe heraclei), powdery mildew (Erysiphe cruciferarum), Alternaria (Alternaria brassicae).
Rate: 0.4L/ha

Critical comments: Maximum Number of applications 3 per crop. Latest time of application 21 days before harvest. 

RESISTANCE MANAGEMENT
Rudis contains prothioconazole, a member of the DMI cross-resistance group. Use Rudis 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. Do not spray more than 3 applications of Rudis per crop or per season.

CROP SPECIFIC INFORMATION
Brussels sprouts, cabbage, broccoli/calabrese, cauliflower:
Rudis may be applied as a foliar spray at a maximum individual dose of 0.4 L product/ha in a water volume of 200 to 500 L/ha, using the higher volume in dense crops. The first application is recommended before disease establishes in the crop (making use of disease forecasting systems as appropriate). This should be followed by further doses at an interval of about 21 days.
As part of a disease resistance management strategy, Rudis should be used in a fungicide spray programme with other products based on different classes of chemistry. The maximum number of doses allowed per crops is 3. At least 21 days must be allowed between the final application and harvest.
For control of brassica leaf spot diseases (Alternaria species, Mycosphaerella brassicicola) or for curative activity against other target diseases, mixing with an approved sticker/wetter adjuvant may enhance the activity of Rudis.
If the crop is intended for processing consult the processor before use of Rudis.
Leeks
Rudis may be applied to leeks as a foliar spray at a maximum individual dose of 0.4 L product/ha in a water volume of 200 to 500 L/ha, using the higher volume in dense crops. The first application is recommended before disease establishes in the crop (making use of disease forecasting systems as appropriate). This should be followed by further doses at an interval of about 21 days.
As part of a disease resistance management strategy, Rudis should be used in a fungicide spray programme with other products based on different classes of chemistry. The maximum number of doses allowed per crop is 3. At least 21 days must be allowed between the final application and harvest.
For control of leek rust, mixing with an approved sticker/wetter adjuvant may enhance the activity of Rudis if in a curative situation or if the crop is very waxy.
Carrots
Rudis may be applied to carrots as a foliar spray at a maximum individual dose of 0.4 L product/ha in a water volume of 200 to 500 L/ha, using the higher volume in dense crops. The first application is recommended before disease establishes itself in the crop (making use of disease forecasting systems as appropriate). This should be followed by further doses at an interval of about 21 days. Typically the first application should be made prior to canopy closure in June/July; this is particularly important for control of Sclerotinia sclerotiorum to ensure that all leaves are adequately protected as the micro-climate under the crop becomes optimal for ascospore release from soil germinating apothecia. To reduce Alternaria infection on the leaves Rudis should be applied in early/mid August, or when first signs of disease appear on the foliage after the 5 true leaf stage of the crop (GS 15) if earlier.
As part of a disease resistance management strategy, Rudis should be used in a fungicide spray programme with other products based on different classes of chemistry. The maximum number of doses allowed per crops is 3. At least 21 days must be allowed between the final application and harvest.
If the crop is intended for processing consult the processor before use of Rudis.

MINOR USE QUALIFICATION
There is limited evidence of crop safety and/or product efficacy available for qualified minor uses and the commercial risk of using this product under this/these Qualified Minor Use(s) is borne entirely by the grower.
Parsnips, swedes and turnips:
Use on parsnip, swede and turnip are Qualified Minor Use Recommendations.

MIXING AND APPLICATION
Shake well before use. Add the required quantity of Rudis to the half-filled spray tank with the agitation system in operation and then fill to the required level. Continue agitation at all times during spraying and stoppages until the tank is completely empty. Spray immediately after mixing.
Ensure spray equipment is clean before use, and filters and jets are checked for damage and blockages.
Spray equipment should be thoroughly cleaned with detergent after use.
Apply as a MEDIUM quality spray (as defined by BCPC).
Boom height and water volume should be adjusted to ensure good coverage of the crop, particularly at later growth stages. In dense crops at later growth stages, higher water volumes should be used as recommended.
For use in tractor mounted/trailed sprayers.
