An oil in water emulsion containing 240 g/litre (22.0% w/w) tau-fluvalinate.
A contact insecticide for the control of aphids in winter and spring wheat and winter and spring barley and control of pollen beetles, cabbage seed weevil and aphids in winter and spring oilseed rape and reduction in Cabbage Stem flea beetle in winter oilseed rape.
DIRECTIONS FOR USE
RESTRICTIONS
Safety to non-target arthropods
When used as directed at 0.15 l/ha, MAVRIK presents a low risk to ground (carabid) beetles, rove (staphylinid) beetles and adult hoverflies (syrphids), though some reduction in numbers may occur. Laboratory studies indicate that reductions in fecundity and egg viability may occur.
Avoid spraying oilseed rape within 6m of the field boundary to reduce effects on certain non-target insects or other arthropods.
Resistance
Control may be reduced where strains of pests resistant to tau-fluvalinate develop.
CROP SPECIFIC INFORMATION
Winter and spring barley, winter and spring wheat (Summer Aphid Control)
Maximum Individual Dose: 0.15 litres/ha
As a guide, spray once when aphids appear on two thirds of the ears and numbers are increasing. Utilise local predictive warnings if available.
Winter barley and winter wheat
(Autumn/ Winter Applications)
Maximum Individual Dose: 0.2 litres/ha
Treat according to specialist advice, normally: High Risk Crops;
Drilled in September/ early October, in virus prone areas or following grass or weedy stubble.
Spray mid October. A repeat application should be made during late autumn/early winter if aphid activity persists.
Medium Risk Crops;
Drilled before mid October, in virus prone areas.
Spray late October/ early November*.
Low Risk Crops;
Drilled after mid October and crops in non virus prone areas.
Follow seasonal warnings based on aphid monitoring in local area*.
N.B. * In mild conditions, later sprays may be worthwhile.
Maximum total dose (all cereal uses)
Winter wheat & barley - 0.4 litres product/ha/crop
Spring wheat & barley - 0.15 litres product/ha/crop
Latest time of application (cereals)
Winter and spring wheat: Before kernel medium milk
Winter and spring barley: Before caryopsis watery ripe
Winter and Spring Oilseed Rape Pollen
(blossom) beetle
Maximum individual dose: 0.2 litres/ha
Optimum control of this pest is achieved by application at the green to yellow bud stage. Apply according to local threshold advice.
A repeat application may be made if pollen beetle activity persists.
Aphids
Maximum individual dose:
0.2 litres/ ha
Not recommended for use to control aphids on spring
rape. Spray according to local advice based on
monitoring.
A repeat application may be made if aphid activity
persists.
Cabbage Stem Flea Beetle
Maximum individual dose:
0.2 litres/ha
Egg hatch can be from October to March but mostly
takes place in late autumn and from mid-late January.
Apply according to local threshold advice.
MAVRIK will reduce damage caused by Cabbage Stem
flea beetle in winter oilseed rape.
For optimal results a repeat application is advisable if
Cabbage Stem flea beetle activity persists.
Cabbage Seed Weevil
Maximum individual dose:
0.2 litres/ha
Apply during flowering period when the numbers of pests reach the threshold, or according to local advice based on monitoring. This is usually between 20% pod set and the end of flowering. For spring varieties, make the first application at green to yellow bud stage. Make a repeat application during flowering as required.
Maximum total dose
Winter oilseed rape - 0.4 litres product/ha/crop
Spring oilseed rape - 0.4 litres product/ha/crop
Latest time of application
Winter and spring oilseed rape: Up to and including end of flowering.
APPLICATION
Good spray cover of the target is essential. Apply through a conventional hydraulic sprayer.
Do not leave the spray liquid in the sprayer for long periods (i.e. during meals or overnight).
Spray Volume
A minimum of 200 litres of water per hectare should be used for all applications. Increase this volume of water in order to obtain good penetration into dense crops.
Spray Quality
Apply as a MEDIUM quality spray as defined by BCPC.
A minimum pressure of 2-3 bar should be used.
Mixing and Spraying
Shake the container of MAVRIK thoroughly before opening. Add half the required volume of clean water to the spray tank. Add the recommended quantity of MAVRIK. Agitate whilst filling the tank to the required water volume and continue agitation during spraying.
Wash out all spray equipment with water immediately after use.
