Restrictions

Do not apply by hand-held equipment

In addition to the maximum number of treatments per crop a maximum of 3 applications of Nativo 75WG may be applied in one calendar year.

If the crop is intended for processing consult the processor before use of Nativo 75WG.


Aquatic Buffer Zone

Respect unsprayed buffer zone as specified for the crop in the Important Information box above.

Horizontal boom sprayers must be fitted with three star drift reduction technology. Low drift spraying equipment must be operated according to the specific conditions stated in the official three star rating for that equipment as published on HSE Chemicals Regulation Directorate’s website.

Maintain three star operating conditions until 30 m from the top of the bank of any surface water bodies.

Do not allow direct spray from horizontal boom sprayers to fall within the distance specified for the crop to the top of the bank of a static or flowing water body, or within 1 m of the top of a ditch which is dry at the time of application. Aim spray away from water.

Buffer zones of more than 5 m cannot be reduced under the LERAP scheme.

When and how to apply

Brussels sprouts, cabbage, broccoli/calabrese and cauliflower

For the control of 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)

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.

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.

Nativo 75WG provides useful protection against white blister but against established infections use a specific oomycete curative fungicide.

Allow new transplants to establish before applying Nativo 75WG as there is potential for some growth regulation seen principally as a transient reduction in vigour of young plants.


Programme planning

Trials show the best response for boosting quality and yield comes from using Nativo 75WG in sequence with Rudis in programmes;

If the crop is disease free when the programme begins, apply Nativo 75WG first (T1) for its protectant activity and plant health promoting characteristics, then follow with Rudis and alternate the two.

If the crop has disease present when the programme begins, apply Rudis first (T1) for its curative activity and greening effect, then follow with Nativo 75WG and alternate the two. At times it may be necessary to use a block of two sprays of Nativo 75WG or Rudis according to the situation faced.

Nativo 75WG applied at the end of a programme will give long lasting protection and enhance storability of produce.

The following diagrams show example programmes in Brussels sprout and autumn/winter cabbage.

Carrots

For the control of Sclerotinia rot (Sclerotinia sclerotiorum) and powdery mildew (Erisyphe heraclei) and for some reduction of Leaf blight (Alternaria dauci).

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.

Nativo 75WG is highly effective against powdery mildew and should be applied no later than the first signs of this disease to maximise its strong protectant activity.

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.

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.


Programme planning

Trials show the best response for boosting quality and yield comes from using Rudis in sequence with Nativo 75WG in programmes.

If the crop is disease free when the programme begins, apply Nativo 75WG first for its protectant activity and plant health promoting characteristics, then follow with Rudis and alternate the two as illustrated below.

If the crop has disease present when the programme begins, apply Rudis first for its curative activity and greening effect, then follow with Nativo 75WG and alternate the two.

At times it may be necessary to use a block of two sprays of Rudis or Nativo 75WG according to the situation faced.

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.

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.

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.
