PESTS CONTROLLED
Biscaya is a neonicotinoid systemic insecticide which provides:
control of pea aphids (Acyrthosiphon pisum) and pea midge damage in peas
control of aphids (cabbage aphid Brevicoryne brassicae and peach-potato aphid Myzus persicae) in broccoli/calabrese, Brussels sprout, cabbage and cauliflower
control of the willow carrot aphid (Cavariella aegopodii) in carrot and parsnip
control of aphids (e.g. virus vectors such as the peach-potato aphid Myzus persicae and potato aphid Macrosiphum euphorbiae) in potatoes
control of pollen beetles in oilseed rape and mustard.
reduction in damage caused by orange wheat blossom midge in wheat

CROP SPECIFIC INFORMATION
There are various restrictions on the number of applications that can be made of any neonicotinoid product on certain crops. Please refer to the ‘PESTICIDE RESISTANCE MANAGEMENT STRATEGY’ for further details.
Application
Apply in a water volume of 200-400 Litres of water per hectare according to the crop and pest. Apply as a MEDIUM quality spray (BCPC).
All varieties of broccoli/calabrese, Brussels sprout, cabbage, cauliflower, carrot, parsnip, peas, potatoes, wheat, oilseed rape and mustard may be treated.
Broccoli/calabrese, Brussels sprout, cabbage and cauliflower
Apply Biscaya at a rate of 0.4 L/ha 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. Follow guidelines in ‘PESTICIDE RESISTANCE MANAGEMENT STRATEGY’ below.
Water Volume: 200-400 L/ha. Use higher water volumes in dense crops.
Combining peas and vining peas
Apply Biscaya at a rate of 0.4 L/ha as pea aphids start to build up in the crop. A second application may be applied if aphid pressure remains high.
Preliminary data have shown that well-timed applications of Biscaya at a rate of 0.4 L/ha 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.
Water Volume: 200-400 L/ha

Carrots and parsnips
Apply Biscaya at a rate of 0.4 L/ha as aphids start to build up in the crop. A second application may be applied if aphid pressure remains high.
Water Volume: 200-400 L/ha
Potatoes
Ware Crops
Apply Biscaya at a rate of 0.4 L/ha 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 at a rate of 0.4 L/ha 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 (see ‘pesticide resistance management strategy).
Biscaya will reduce the transmission of potato viruses when used as part of an insecticide programme for virus prevention.
Water Volume: 200 – 400 L/ha: use a higher volume on dense crops.
Oilseed Rape and mustard
Apply Biscaya at a rate of 0.3 L/ha at green bud stage if pollen beetle numbers are at threshold levels.
Water Volume: 200-400 L/ha
Wheat
Apply Biscaya at a rate of 0.4 L/ha during ear emergence as soon 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 GS55-59 are most susceptible to damage. 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
PESTICIDE RESISTANCE MANAGEMENT STRATEGY
Total reliance on one pesticide will hasten the development of resistance; pesticides of different chemical types or alternative control methods should be included in a planned programme.
Alternating insecticides with different modes of action is a recognised anti-resistance strategy and ‘Biscaya’ should always be used in conjunction with other insecticides of a different mode of action.
This includes consideration of sequences involving seed or soil treatments followed by foliar sprays.
Brassicas
Use no more than two foliar applications of any neonicotinoid insecticide (e.g. acetamiprid, thiacloprid) on any crop. Two foliar applications are permitted regardless of whether a neonicotinoid insecticide has previously been used on the crop as a seed or module treatment. Where a neonicotinoid seed or soil treatment has been used, the first subsequent foliar spray should be with a non-neonicotinoid containing product with a different mode of action.
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. Alternate with non-neonicotinoid containing products between foliar applications of neonicotinoids.

Potato
Use no more than a single application of any neonicotinoid insecticide on ware potatoes, and no more than two applications of any neonicotinoid insecticide on seed potatoes.
Oilseed rape
Use no more than one foliar application of any neonicotinoid insecticide on oilseed rape.
Growers should consult the IRAG website for further information on the current resistance management strategy for pollen beetle, in particular the use of thiacloprid in areas of high resistance risk, or where a pyrethroid has been used but pollen beetle populations remain above the treatment threshold.
Biscaya should always be applied at the full recommended rate of use and in sufficient water volume to achieve the required spray penetration into the crop and uniform coverage necessary for optimal pest control.

MIXING AND SPRAYING
Shake well before use. Add the required quantity of Biscaya to the half-filled spray tank with the agitation system in operation, and fill to the required level. Continue agitation at all times during spraying and stoppages until the tank is completely empty. Spray immediately after mixing. Wash equipment thoroughly, immediately after use, and drain
