How does Biscaya work?

Formulated as an oil dispersion with O-TEQ formulation technology, Biscaya brings enhanced wetting properties.

The O-TEQ formulation accelerates leaf uptake, systemic movement within the leaf and rainfastness: essential traits for successful aphid control in dense, rapidly growing crops such as potatoes.

 undefined

The O-TEQ formulation also accelerates Biscaya’s translaminar and systemic mobility to ensure consistent control throughout the crop canopy. Aphids feeding on the underside of a leaf, not directly targeted with a spray, are just as effectively controlled as those on the upper leaf surface.

When and how to apply

Broccoli/Calabrese, Brussels sprout, Cabbage and Cauliflower

 For the control of cabbage aphid Brevicoryne brassicae and peach–potato aphid Myzus persicae

 Apply Biscaya as aphids start to build up in the crop.

 On autumn/winter crops with longer growing periods destined for later harvesting, one or both of the neonicotinoid foliar applications should be targeted at Brevicoryne brassicae and should be applied late in the season when numbers of Myzus persicae are low.

Levels of control may be reduced where high, established populations are present. In such circumstances a second application may be required.

Biscaya may be used up to 2 times in a programme in alternation with non- neonicotinoid insecticides of a different mode of action. Do not use Biscaya in consecutive sprays.

For resistance management use no more than two foliar applications of any neonicotinoid insecticide on any crop.

Programme planning

Use Biscaya for quick ‘knockdown’ when crop structure is more open and aphids are more exposed to sprays and at the end of the season when colder conditions prevail.

Use Movento for long lasting protection in dense actively growing crops, when pests are more hidden.

The following diagram shows how these principles can be applied to the planning of aphid control in autumn/winter cabbage. This approach can apply equally to broccoli/calabrese, cauliflower and Brussels sprouts where hidden pests get into the florets, curd or buttons and should also provide effective control of whitefly, even in years of high pressure.

Combining Peas and Vining Peas

For the control of pea aphids (Acyrthosiphon pisum) and pea midge.

Pea aphids

Apply Biscaya as pea aphids start to build up in the crop.  A second application may be applied if aphid pressure remains high.

Pea midge

Preliminary data have shown that well-timed applications of Biscaya can give useful control of pea midge and improvement in pod numbers.

Inspect plants at early flowering (flower buds enclosed) and apply the first spray if adult midges are found or according to local warnings. Repeat 7-10 days later.

Carrots & Parsnips

For the control of willow carrot aphid (Cavariella aegopodii)

Apply Biscaya as aphids start to build up in the crop. A second application may be applied if aphid pressure remains high.

Use from May to mid-July when plants are actively growing. There needs to be sufficient leaf area for uptake – at least one true leaf, preferably two leaves –  and good movement in the phloem for good redistribution to vulnerable tissues. The following diagram illustrates a typical foliar spray programme for aphid control in carrots beginning when aphids appear in the crop at the first true leaf stage.

Field Beans

For the control of pea aphids (Acyrthosiphon pisum) and reduction of damage from bruchid beetles (Bruchus rufimanus).

Applications must be made between 1st May and 31st July only and a  minimum interval of 10 days must be observed between applications. A maximum of 2 applications in total are permitted per crop regardless of the target pest.

Bruchid beetle

For the reduction of damage from bruchid beetle, most reliable results will be obtained from a timely application of 0.4 L/ha when temperatures reach 20oC or more on 2 consecutive days at early pod set. Repeat a minimum of 10 days later.

Pea aphid

For the control of pea aphid, apply as populations start to build up in the crop.

Potatoes

For the control of virus vectors such as the peach-potato aphid Myzus persicae and potato aphid Macrosiphum euphorbiae in potatoes. Biscaya will reduce the transmission of potato viruses when used as part of an insecticide programme for virus prevention.

Ware Crops

Apply Biscaya when aphids reach threshold levels. Should further applications be required, use
a non-neonicotinoid insecticide of a different mode of action.

Seed crops

Apply Biscaya from crop emergence. Biscaya may be used up to 2 times in a programme in alternation with non-neonicotinoid insecticides of a different mode
of action.

Do not use Biscaya in consecutive sprays. Use no more than two applications of any neonicotinoid-containing product on seed potatoes,

Spring OSR & Mustard

For the control of pollen beetle.

Apply Biscaya at green bud stage if pollen beetle numbers are at threshold levels.

Winter OSR

For the control of pollen beetles and peach–potato aphid (Myzus persicae).

For use on winter oilseed rape, only one application is authorised in the autumn and one application in the spring of any neonicotinoid insecticide.


Peach–potato aphid

For control of peach–potato aphid in winter oilseed rape in the autumn apply Biscaya from the 2 leaf unfolded stage as Myzus persicae start to build up in the crop.

This application can be followed by one application for the control of pollen beetle in the spring.

Pollen beetle

Apply Biscaya at green bud stage if pollen beetle numbers are at threshold levels.

For resistance management use no more than two foliar applications of any neonicotinoid insecticide on winter OSR.

Growers should consult the UK-
IRAG website for further information
on the current advice and resistance management strategy for pollen beetle and Myzus persicae, particularly in relation to pyrethroid resistance which is widespread in both pests.

Wheat

For the reduction in damage caused by orange wheat blossom midge

Apply Biscaya during ear emergence as soon as a threshold of adult orange wheat blossom midges has been reached.

Use pheromone traps or yellow sticky traps to monitor adult activity in crops at risk.

Crops at GS 55–59 are most susceptible to damage. Do not apply to wheat before first spikelet visible stage (GS 51).


Consult HGCA literature or a qualified agronomist for additional information on the pest and spray thresholds.

Aphids present on the crop at application will also be controlled.

Water volume 200 L/ha.

Resistance Management

Total reliance on one pesticide will hasten the development of resistance; pesticides of different chemical types or alternative control measures should be included in a planned programme.

Alternating insecticides with different modes of action is a recognised anti­ resistance strategy and Biscaya should be used in alternation with insecticides of a different mode of action, giving consideration to the overall treatment programme on the crop against a range of pests.

ALWAYS READ THE LABEL BEFORE USE.
