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.

CARIAL FLEX can be used on all varieties of potatoes including seed potatoes.

PROPERTIES OF CARIAL FLEX

CARIAL FLEX is a foliar fungicide for the preventative control of late blight (Phythophthora infestans) in potatoes and is highly active against spore germination. Uptake into the leaf tissue assures good translaminar and local systemic activity and inhibits mycelial growth during the incubation period whilst also giving some limited curative activity.
 
BACKGROUND TO POTATO BLIGHT CONTROL
Late blight (Phytophthora infestans) is potentially a devastating disease of potatoes. In commercial production, a season long disease prevention policy is essential. First of all ensure that other control methods are being satisfactorily applied:
1. Prevent re-growth on potato dumps.
2. Destroy all groundkeepers.
3. Plant disease free seed.
4. Use generous soil ridges to protect tubers.
 
TIMING
CARIAL FLEX is a protectant and curative fungicide so following good agricultural practice, the programme should start BEFORE blight enters the crop. Commence spraying at the first blight warning or when local weather conditions are favourable for the disease. However, applications 1 day after an infection event has occurred have shown to give good levels of control.

Intervals between applications of CARIAL FLEX should be reduced as blight risk increases, so that protection of the crop can be maintained.

Applications of CARIAL FLEX should be made at 7-10 day intervals depending on disease pressure. As disease pressure and the risk of late blight infection increase, the interval should be shortened.

Rates of Use

Apply CARIAL FLEX at 0.6 kg product per hectare. Up to six applications may be made per crop. Allow a minimum of 7 days between applications.
 
MIXING AND SPRAYING
Spray Volume
Apply CARIAL FLEX in a recommended 200-600 litres of water per hectare.

Spray Nozzles

A medium quality spray* is preferred for application of CARIAL FLEX (*as defined by The British Crop Protection Council). A spray pressure of 2-3 bar is recommended.

Mixing
Make sure the sprayer is clean and set to give an even application at the correct volume.
Fill the spray tank with half the required volume of clean water and start agitation. Add the required amount of CARIAL FLEX and continue agitation whilst adding the rest of the water.
Agitate the mixture thoroughly before use and continue agitation during spraying and any stoppages.
Thoroughly wash all spray equipment with water immediately after use.
Do not leave the spray liquid in the sprayer for long periods (such as during meal breaks or overnight).
 
RESISTANCE MANAGEMENT
CARIAL FLEX contains mandipropamid, a CAA fungicide (FRAC code no. 40) and cymoxanil, a cyanoacetamideoxime fungicide (FRAC code no. 27).. To minimise the risk of resistance development in the pathogen population the following guidelines for blight fungicides (based on an average number of 12 fungicide applications/season for blight control) should be followed:- 1. Where possible, use an alternating strategy using fungicides from different mode of action groups. 2. Where CAA fungicides are applied as a mixture (co-formulated or as a tank mix) up to six applications (or max. of 50% of the total number of applications) may be made per crop or season. 3. No more than 3 applications of any CAA fungicide should be made consecutively. 4. Further information on suitable tank mix products and resistance management strategies is available from FRAG and BPC websites.
