A broad spectrum systemic fungicide with protectant and curative properties for use on Brussels sprouts, cabbage, broccoli/calabrese, cauliflower and carrots.

Nativo 75WG gives carrots, cauliflowers, cabbages, broccoli and sprouts superb visual appeal. With broad-spectrum disease protection and mesostemic action, it keeps crops cleaner for longer. Used in a programme with Rudis, you can achieve even better Class 1 yields and quality.

Quality is the only driver for a successful crop with the main focus on visual quality. Nativo 75WG delivers this through the protection and strobilurin boost of trifloxystrobin, safely combined with the curative and protectant triazole properties of tebuconazole.

In brassicas it is recommended that the first application is applied before disease establishes in the crop (making use of disease forecasting systems as appropriate).
To control 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.
Typically in carrots 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 before 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 the five leaf stage if earlier.

Main advantages
Broad spectrum disease control
Long-lasting protectant activity
Enhanced plant health from the strongest strobilurin in vegetable crops
Resistance management built-in
Crop-safe WG formulation

Always use full rates to achieve best control levels and good resistance management practice
Remember to follow FRAC guidelines, especially for strobilurins (QoI)-based formulations, as only up to 50% of the programme may be made up of these
Always dissolve Nativo 75WG in fresh, clean water, ensure it is thoroughly mixed and then add the other product to the spray tank
Note: Growers with Nativo 75WG bearing the old MAPP number 13057 can still use the product on leeks up to 30 June 2016, but product with the new MAPP number 16867 is no longer authorised for leeks. Work is ongoing to have this crop re-instated. Always check the CRD website for the latest product information

An effective programme has three stages:
Clean start: ensure the best start possible with a clean crop. If any disease has already crept in, use a curative product such as Rudis to clean up. Otherwise maximise the clean leaf with strobilurin-based chemistry for protectant activity and greening/physiological benefits.
Build and protect quality: as the crop moves onto the second spray and beyond, supporting plant growth and development is the priority. Alternating chemistry is essential as part of good resistance management practice.
Secure quality: later in the season maintaining quality until harvest needs attention so that marketable yield and profits can be fully realised. Choosing the right products to prolong healthy appearance and react to late season infections is vital.

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, and carrots.
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.

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 2 applications of Nativo 75WG to Brussels sprouts, cabbage, broccoli, calabrese or cauliflower and more than 3 applications to carrots.

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.

DISEASES CONTROLLED
Brussels sprouts, cabbage, broccoli/calabrese and cauliflower: 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).

Carrots: Leaf blight (Alternaria dauci)*, Sclerotinia rot (Sclerotinia sclerotiorum), powdery mildew (Erisyphe heraclei).
* Some reduction

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.
The effectiveness using 3 star drift reduction technology may be reduced.

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 0.36 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 a further dose at a minimum interval of 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 numberof doses allowed per crops is 2. At least 21 days must be allowed between the final application and harvest.
Use of an officially listed adjuvant with Nativo 75WG is likely to improve control of ring spot in a curative situation especially under cool conditions.
If the crop is intended for processing consult the processor before use of Nativo 75WG.

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 a minimum interval of 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 crops 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.

MIXING AND CLEANING
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.
After use all application equipment should be washed/cleaned with water or dilute detergent solution and thoroughly rinsed more than once, with washings applied to the crop to be treated whilst keeping within the maximum application rates.
