A fungicide for the control of light leaf spot, Phoma leaf spot/stem canker and Sclerotinia stem rot diseases in oilseed rape.

FOR USE ONLY AS AN AGRICULTURAL FUNGICIDE

WINTER OILSEED RAPE
a) First application at or before BBCH 19 (see Other specific restrictions:)
Maximum individual dose: 0.75 litres product per hectare
Maximum total dose: 1.5 litres product /ha

b) First application at or after BBCH 20 (see Other specific restrictions:)
Maximum individual dose: 1.0 litres product per hectare
Maximum total dose: 2.0 litres product /ha

For winter oilseed rape (a) and (b) are ALTERNATIVES and cannot be used interchangeably orcombined in any manner

SPRING OILSEED RAPE
Maximum individual dose: 1.0 litres product per hectare
Maximum total dose: 2.0 litres product /ha
Latest time of application: 56 days before harvest

Other specific restrictions: For use on winter oilseed rape; where the first application of Corinth is made to winter oilseed rape before BBCH 19, then only a single application of a maximum of 0.75 litres product/ha may be made after BBCH 20 (i.e. the alternate GAP 2 x 1.0 litre product/ha rate after BBCH 20 is not permitted). A minimum interval of 21 days must be observed between
applications.

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.
Corinth contains two DMI fungicides, a triazolinthione (prothioconazole) and triazole (tebuconazole) recommended for control of a range of diseases on oilseed rape.
A minimum interval of 21 days must be observed between applications.
PROTECT FROM FROST

CROPS
Corinth may be used on all commercial varieties of oilseed rape.

RATE OF USE
Winter oilseed rape
a) Apply Corinth at 0.75 L/ha at or before BBCH 19 and then at a maximum of 0.75 L/ha for follow up applications. The maximum total dose per crop is:- 1.5. litres per hectare
This programme may result in reduced levels of control of Phoma stem canker and light leaf spot.
Or
b) Where the first application is made at or after BBCH 20 apply Corinth at a maximum of 1.0 L/ha. A follow up application can also be applied at a maximum of 1.0 L/ha.
The maximum total dose per crop is:- 2.0 litres per hectare.

Spring oilseed rape
Apply Corinth at 1.0 L/ha litre.
The maximum total dose per crop is:- 2.0 litres per hectare
A minimum interval of 21 days must be observed between applications.

APPLICATION
Water volume
Apply Corinth in 200-300 litres per hectare water. A spray pressure of 2-3 bar is recommended.

Spray quality
Apply as a MEDIUM spray quality (as defined by BCPC).

Latest Permitted Timing
In oilseed rape Corinth may be applied up to 56 days before harvest.

Mixing
Thoroughly shake the pack before use. Add the required quantity of Corinth 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.

General
Sprayers should be thoroughly cleaned with water and detergent after use, and filters and jets checked for damage and blockages. Boom height should be adjusted to ensure even coverage of the crop, particularly at later growth stages. The correct height is one at which the spray from alternate nozzles meets just above the crop. In dense crops, at later growth stages, higher water volumes should be used.

DISEASES CONTROLLED
Oilseed rape
Light leaf spot*, Phoma leaf spot and reduction of stem canker severity, and Sclerotinia stem rot.
*Corinth will provide moderate control of this disease

APPLICATION TIMING
OILSEED RAPE
Light Leaf Spot
Apply Corinth in autumn/winter (usually late October to early December) protectively. A follow up spray may be required in early spring from the onset of stem elongation, depending on disease development.
Strains of light leaf spot resistant to azole fungicides are known to exist. To avoid the development of resistance apply Corinth protectively in response to disease forecasts. Where possible, avoid the use of products containing azoles when targeting other diseases such as Sclerotinia at mid-flowering.

Phoma Leaf spot/Stem Canker
Apply Corinth in autumn at the first sign of disease. Repeat application in late autumn/winter, if disease symptoms reoccur.

Sclerotinia stem rot (Sclerotinia sclerotiorum)
Apply Corinth at early to full flower

RESISTANCE STRATEGY
Repeated application of Corinth alone should not be used on the same crop. Tank mixtures or alternation with fungicides having a different mode of action have been shown to protect against the development of resistant forms of disease. For further advice on resistance management in DMI’s contact your agronomist or specialist advisor, and visit the FRAG-UK website.

CAUTION: The possible development of disease strains resistant to Corinth cannot be excluded or predicted. Where such resistant strains occur, Corinth is unlikely to give satisfactory control.
