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.
Nativo 75WG is recommended for control of a wide range of diseases on Brussels sprouts, cabbage, broccoli/calabrese, cauliflower, carrots and leeks.
For best disease control and yield benefit Nativo 75WG should be applied at an early stage of disease development, before infection spreads to new crop growth.

Dark leaf spot (Alternaria brassicae & Alternaria brassicicola), light leaf spot (Pyrenopeziza brassicae), ring spot (Mycosphaerella brassicicola), powdery mildew (Erysiphe cruciferarum), Phoma leaf spot (Phoma lingam) and white blister (Albugo candida).
Rate: 0.4 kg/ha
Critical comments: Maximum number of applications 2per crop. Maximum total dose 0.8 kg/ha. Latest time of application 21 days before harvest.

BRIUSSELS SPROUT, CABBAGE
Diseases: Dark leaf spot (Alternaria brassicae & Alternaria brassicicola), light leaf spot (Pyrenopeziza brassicae), ring spot (Mycosphaerella brassicicola), powdery mildew (Erysiphe cruciferarum), Phoma leaf spot (Phoma lingam) and white blister (Albugo candida).

0.4 kg/ha
Critical comments: 
Maximum number of applications 3 per crop. Maximum total dose 1.2 kg/ha. Latest time of application 21 days before harvest.

Rate: 0.3kg/ha
Critical comments: Maximum number of applications 3 per crop. Maximum total dose 0.9 kg/ha. Latest time of application 21 days before harvest.

LEEKS
Diseases: Leek rust (Puccinia allii), white tip (Phytophthora porri) and purple blotch (Alternaria porri).
Rate: 0.4 kg/ha
Critical comments:
Maximum number of applications 3 per crop. Maximum total dose 1.2 kg/ha. Latest time of application 21 days before harvest.

RESISTANCE MANAGEMENT
Nativo 75WG contains trifloxystrobin, a member of the Qol cross-resistance group. Use Nativo 75WG 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 Nativo 75WG to Brussels sprouts, cabbage, carrots or leeks and more than 2 applications to broccoli, calabrese or cauliflower. Also in accordance with FRAC guidelines for pre-mix Qol fungicides the number of applications of Qol containing products should be no more than 50% of the spray programme.

Based on limited data, useful reductions in Stemphylium botryosum in leeks may be achieved and some control of Cladosporium allii (leaf blotch) would also be expected.
The possible development of disease strains resistant to Nativo 75WG cannot be excluded or predicted. Where such resistant strains occur, Nativo 75WG is unlikely to give satisfactory control.

CROP SPECIFIC INFORMATION
Brussels sprouts, cabbage, broccoli/calabrese and cauliflower:
Nativo 75WG may be applied to Brussels sprouts, cabbage, broccoli/calabrese and cauliflower as a foliar spray at a maximum individual dose of 0.4 kg 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, Nativo 75WG 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 for Brussels sprouts and cabbage and 2 for broccoli/calabrese and cauliflower. 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, mixing with an approved sticker/wetter adjuvant may enhance the activity of Nativo 75WG.
If the crop is intended for processing consult the processor before use of Nativo 75WG.
For crop safety reasons avoid applying Nativo 75WG to cauliflowers or broccoli/calabrese once flowering has commenced.
Carrots:
Nativo 75WG may be applied to carrots as a foliar spray at a maximum individual dose of 0.3 kg 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 Nativo 75WG should be applied in early/mid August, or when first signs of disease appear on the foliage after crop GS 15 if earlier.
As part of a disease resistance management strategy, Nativo 75WG 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.
Under certain circumstances e.g. where curative activity is required for Alternaria leaf blight, mixing with an approved sticker /wetter adjuvant may enhance the activity of Nativo 75WG.
If the crop is intended for processing consult the processor before use of Nativo 75WG.
Leeks:
Nativo 75WG may be applied to leeks as a foliar spray at a maximum individual dose of 0.4 kg 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, Nativo 75WG 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 or Alternaria porri, mixing with an approved sticker /wetter adjuvant may enhance the activity of Nativo 75WG.
If the crop is intended for processing consult the processor before use of Nativo 75WG.

MIXING
Add the required quantity of Nativo 75WG 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.
Sprayers should be THOROUGHLY CLEANED before use and filters and jets checked for damage and blockages.
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.

COMPATIBILITY
Nativo 75WG may be applied as a tank-mix with a range of products. Contact Bayer CropScience for compatibility information on specific tank-mixes. Full manufacturer’s instructions must be followed for each tank-mix component.
