DIRECTIONS FOR USE


IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be carefully read in order to obtain safe and successful use of this product.


RESTRICTIONS
Certain apple varieties are highly sensitive to azoxystrobin. As a precaution PRIORI® Gold should not be applied when there is a risk of spray drift onto neighbouring apple crops. Spray equipment used to apply PRIORI Gold to other crops should not be used to treat apples.

GENERAL INFORMATION


PRIORI Gold is a suspension concentrate containing 125 g/l azoxystrobin and 125 g/l difenoconazole.
PRIORI Gold has systemic activity, with protectant properties for use in all commercial varieties of
winter and spring oilseed rape, sugarbeet and fodder beet.

CROP SPECIFIC INFORMATION
OILSEED RAPE
Before applying PRIORI Gold, ensure the crop is free from any stress caused by environmental or agronomic effects. Best results will be achieved from applications made as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems.

WINTER OILSEED RAPE
A maximum of only two applications can be made per winter oilseed rape crop.
Stem canker (Phoma lingam)

Timing
Spray protectively with 1 litre of PRIORI Gold per hectare in the Autumn for the reduction of Stem canker (Phoma lingam) from the 4 expanded true leaf stage (GS 14). Where appropriate, a second application can be made in the Spring from the start of stem elongation and no later than individual flower bud visible (GS 30-55).

Rate Of Use
1 litre per hectare. Two applications per crop.
Sclerotinia stem rot (Sclerotinia sclerotiorum) – moderate control

Timing
Spray one application protectively with 1 litre of PRIORI Gold per hectare in the Spring for the moderate control of Sclerotinia stem rot (Sclerotinia sclerotiorum) from yellow bud until the end of flowering (GS 59-69).

Rate Of Use
1 litre per hectare. One application per crop.

SPRING OILSEED RAPE
A maximum of only one application can be made per spring oilseed rape crop.
Stem canker (Phoma lingam)

Timing
Apply 1 litre of PRIORI Gold per hectare from stem elongation and no later than individual flower bud stage (GS 30-55).

Rate Of Use
1 litre per hectare. One application per crop
Sclerotinia stem rot (Sclerotinia sclerotiorum) – moderate control

Timing
Apply 1 litre of PRIORI Gold per hectare between yellow bud and the end of flowering (GS 59-69).

Rate Of Use
1 litre per hectare. One application per crop

SUGARBEET AND FODDER BEET
Timing
Apply PRIORI Gold at the first signs of the disease, before the disease becomes established. PRIORI
Gold gives prolonged protection from re-infection, but a second application can be applied where crops are at risk from later attacks.
Apply PRIORI Gold only between Crop cover complete: leaves cover 90% of ground and beet root has reached harvestable size (BBCH GS39-49).

Rate Of Use
1 litre per hectare.
Two applications per crop allowing a minimum interval of 21 days between applications.

MIXING AND SPRAYING
Ensure that the sprayer is clean and correctly set to give an even application at the required volume.
Half-fill the spray tank with clean water and start agitation. Shake the container and add the required amount of PRIORI Gold to the sprayer using a filling device (e.g. induction bowl or closed transfer unit) or by direct addition to the sprayer tank.
Wash out containers thoroughly, preferably using an integrated pressure rinsing device, or manually rinse three times. Add washings to the sprayer at the time of filling. Complete filling to the required volume and continue to agitate throughout the spraying operation.
Do not leave the spray liquid in the sprayer for long periods (such as during meal breaks or overnight).
Volume of Water and Spraying
Apply in a recommended 200-400 litres of water per hectare using a medium quality spray (BCPC) at a pressure of at least 2 bar. Apply through conventional crop spraying equipment.

After Spraying
Thoroughly wash out sprayer according to the manufacturer’s guidelines and dispose of washings and clear containers according to DEFRA Code of Practice and local water authority guidelines
