For the control of a wide range of diseases in grapes, field tomatoes, potatoes and vegetable brassicas

DIRECTIONS FOR USE:
It is an offence to use this product on animals.
Rainfall:
DO NOT apply if rainfall is likely within 6 hours following application. Heavy rain following treatment will remove much of the fungicide from treated plant tissue and if disease pressure remains high, earlier re-treatment will be necessary.

GRAPES
Disease: Botrytis, Downy Mildew and Phomopsis (dead arm)
Rate: 100 mL / 100 Litres (or not less than 1 litre per hectare)
Comments: Apply at early and late flowering; just prior to bunch closure and again in the period from the beginning of berry ripening up until 28 days before harvest. Use alternative fungicides, particularly for phomopsis control, in the critical pre-flower period. Add Contact Low Foam surfactant at a rate of 25mL/100 litres. The rate expressed is for high volume spraying to run-off. For concentrate spraying adjust dilution rate accordingly

FIELD TOMATOES
Disease: Botrytis, Sclerotinia and Late Blight
Rate: 750 mL/ha 
Comments: Apply at early flowering and again approximately 14 days later, towards the end of flowering. Apply in a minimum of 500 litres water per hectare and increase if necessary to ensure complete coverage. The period of sclerotinia control is four to eight weeks, and after the second application of Gem Fungicide, alternative approved fungicides may be required in high risk situations. For the control of late blight after flowering, use alternative approved fungicides for the remaining duration of the crop. Add Contact Low Foam surfactant at a rate of 25 mL/100 litres.

POTATOES
Disease: Early Blight, Late Blight and Sclerotinia
Rate: 250 mL/ha (for late blight and sclerotinia) or 200 mL/ha plus mancozeb (800 grams ai)/ha if early blight is also likely
Comments: Apply at 7-10 day intervals. Use the shorter interval under severe pressure conditions. Apply when the crop has fully emerged but before any sign of disease, using sufficient water per hectare to obtain complete coverage. Add Contact Low Foam surfactant at a rate of 25mL/100 litres.

Disease: Powdery Scab 
Rate: 4 litres/ha
Comments: Apply in 500 litres of water to cultivated ground prior to planting. Within 2 hours of application incorporate thoroughly into the soil to a depth of 15cm, using either a rotary hoe or power harrow.

VEGETABLE BRASSICAS
Disease: Clubroot 
Rate: 4 litres/ha
Comments: Apply in 500 litres of water to cultivated ground prior to transplanting. Ensure thorough incorporation to transplant root depth (not more than 10cm) within 2 hours of applying, using a rotary hoe or power harrow. Soil should be moist at application and the crop transplanted within 2 days. At least 20mm of overhead irritation should be applied soon after planting to further assist the distribution of Gem Fungicide throughout the upper soil profile. Disease control may be reduced if longer transplant or irrigation intervals occur.

It is an offence for users of this product to cause residues exceeding the relevant MRL in the New Zealand (Maximum Residues Limits of Agricultural Compounds) Food Standards.
