FORMULATION & ACTIVE INGREDIENT: FUBOL GOLD WG is a water dispersible granule containing 3.88% w/w metalaxyl-M and 64% w/w mancozeb.
FUBOL GOLD is a co-formulation of mancozeb and metalaxyl-M for the control of foliar blight in potatoes and downy mildew in bulb onions and shallots.
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. FUBOL GOLD WG is a water dispersible granule containing 3.88% w/w metalaxyl-M and 64% w/w mancozeb for control of foliar blight of potatoes and the useful control of downy mildew (Peronospora destructor) in bulb onion and shallots .
RESTRICTIONS
FUBOL GOLD WG should not be used on potato crops which follow a potato crop that has been grown in the same field in that season.
DISEASES CONTROLLED
FUBOL GOLD WG is a fungicide with systemic and protectant properties which controls when used as directed:
Foliar blight in potatoes
Downy mildew (Peronospora destructor) in bulb onions and shallots: useful control

CROP SPECIFIC INFORMATION
POTATOES
Timing
The systemic component of FUBOL GOLD WG (metalaxyl-M) works best on young actively growing foliage. It is recommended, therefore, that FUBOL GOLD WG is used for the first part of the blight control programme. FUBOL GOLDWG should not be applied when blight is already established in the crop i.e. do not use curatively
Latest time of application: Before the end of active growth of the potato haulm or before the end of August, whichever is the earlier (provided the statutory conditions of use are met).
Spraying with FUBOL GOLD WG should begin either:
1.Immediately risk of blight occurs in the area irrespective of the crop growth stage. OR
2. In the absence of blight risk, spraying should begin as crops meet along (not across) the rows, generally when plants are 15-20 cm high.
Further sprays of FUBOL GOLD WG should be made according to blight risk. Potatoes are at risk of infection with potato blight where warm (temperature around 8-10 °C or above) humid (rain, fog, mists or irrigation) weather conditions exist for at least two consecutive days or nights. However, any period of warmth and humidity will increase the blight risk. After treatment of first and second early crops, haulm remaining after harvest must be completely destroyed or removed immediately to minimise blight pressure on neighbouring maincrop potatoes.
Spray Intervals
Growers should monitor the weather conditions in the immediate vicinity of their potato crops to determine blight risk. Official notification of blight risk may be inadequate to ensure optimum blight protection. A maximum spray interval of 14 days should be used.
Lowrisk - Spray every 14 days
Low risk conditions occur before blight risk occurs or after the spray programme has commenced, or when weather conditions become unfavourable for blight i.e. hot, dry weather.
High risk - Spray every 10 days
High risk conditions occur if weather is conducive to blight, the crop is irrigated, or if active blight is present on crops in the area or on dumps or volunteers. The risk is especially high when high risk conditions coincide with periods of unusually rapid growth.
Severe risk - Spray every 7 days
Severe risk conditions occur where weather continues conducive to blight and all of the High risk factors occur.
Monitoring of Spray Programme
Sprayed crops should be monitored throughout the complete period of the protection programme. If blight is identified in crops sprayed with FUBOL GOLD WG stop using FUBOL GOLD WG. Switch to a curative fungicide containing an active substance with a different mode of action which should be sprayed within 7 days of the last FUBOL GOLD WG spray. Do not in any circumstances return to a FUBOL GOLD WG programme. For desiccation of the infected crop, consider use of a non-selective herbicide which is approved for this use.
Subsequent Treatments
Where crops are to be harvested before natural senescence, follow up treatments after FUBOL GOLD WG should be made using a protectant fungicide and starting no later than 10 days after the last FUBOL GOLD WG application. At least 2 protectant sprays should be applied to the crop before harvesting, desiccation or haulm destruction. N.B. Products containing phenylamide fungicides (e.g. Epok or Galben M) must not be used after FUBOL GOLD WG.
Rates of Use
Apply at 1.9 Kg/ha. No more than 3 applications of FUBOL GOLD WG should be made to any one crop.
BULB ONIONS AND SHALLOTS
Timing
Before applying FUBOL GOLD WG, ensure the crop is free from any stress caused by environmental or agronomic effects. For optimum disease control FUBOL GOLD WG should be used at the first sign of disease infection or preferably preventatively when a predictive assessment shows conditions favourable for disease development.
Rates of Use
FUBOL GOLD WG should be applied at 1.9 Kg/ha:
For optimum downy mildew control in onions a 7 to10 day spray interval should be maintained
Applications to established downy mildew infection are unlikely to give reliable control No more than 3 applications of FUBOL GOLD WG should be made to any one crop.
For optimum downy mildew control in onions a 7 to10 day spray interval should be maintained
Applications to established downy mildew infection are unlikely to give reliable control No more than 3 applications of FUBOL GOLD WG should be made to any one crop.
STORAGE AND PROCESSING
The effects of FUBOL GOLD WG on onion and shallot bulbs has not been fully assessed. Effects on bulb quality that may affect storage characteristics cannot be ruled out. Where a crop is destined for processing, consult your processor before treating with FUBOL GOLD WG.
RESISTANCE MANAGEMENT
Strains of the potato blight fungus resistant to phenylamide fungicides (metalaxyl, metalaxyl-M and benalaxyl) occur.
FRAC (Fungicides Resistance Action Committee) have defined guidelines for the effective management of blight and downy mildews with these fungicides, which are incorporated in this label.
No more than three applications of phenylamide-containing products should be applied to a crop of potatoes, bulb onions or shallot.
When levels of phenylamide resistance in blight are high, additional restrictions on the use of phenylamide fungicides may be necessary. Growers should always ensure that they follow the latest resistant management advice.
Since the occurrence of resistance cannot be forecast, neither Syngenta UK Limited nor its distributors can accept responsibility for any loss or damage to crops caused by the failure of FUBOL GOLD WG to control resistant strains
MIXING AND SPRAYING
Mixing
Make sure the sprayer is set to give an even application at the correct volume. In all cases add FUBOL GOLD WG to the spray tank first, followed by any additional products.
Dry Mixing – Sprayers with Induction Hoppers
Fill sprayer to 15% of tank capacity with water and start agitation. Pour FUBOL GOLD WG into the induction hopper and open valve in bottom of hopper to suck the granules into the circulating spray mix. Continue adding FUBOL GOLD WG until loading is complete. Wash down any granules on the hopper wall and close valve. Rinse packs in the normal manner.
Sprayers without Induction Hoppers
Fill sprayer with a minimum of 15 cms of water in the bottom and agitate vigorously. Pour FUBOL GOLD WG through the sprayer lid, triple rinse containers into the sprayer and then add the remainder of water.
Agitate the mixture thoroughly before use and continue agitation during spraying.
Thoroughly wash all spray equipment with water after use.
Spray Volume
Not less than 200 litres of water per hectare.
Spraying
A MEDIUM quality spray should be used (as defined by BCPC) when FUBOL GOLD WG is to be applied alone and when used in mixture with other products.
Sprays should be applied at a pressure of 2–3 bar.
