DIRECTIONS FOR USE
IMPORTANT: This leaflet is approved as part of the label. All instructions on this leaflet and on the label should be read carefully in order to obtain successful results from the use of this product.

RESTRICTIONS
For Professional use only.
DO NOT spray crops suffering from drought or other physical or chemical stress.
DO NOT spray wet crops liable to run-off. Some varieties of ornamentals are particularly sensitive to chemical sprays, so treat a small number of plants first to determine the reaction.
Do not apply this product in tank mixture with a triazole-containing fungicide when bees are likely to be actively foraging in the crop. Consult manufacturer.
PROTECT FROM FROST STORE IN A SAFE DRY PLACE designated as an agrochemical store
Decis is rainfast 1 hour after spraying. It can be applied in frosty weather provided foliage is not covered with ice.
Very high temperatures, greater than 35°C (greater than 95°F) may reduce efficacy or
persistence.
Avoid spraying within 5 m of the field boundary to reduce effects on non-target insects or other arthropods when applied to the following crops: Flower/foliage and woody ornamental plant production (outdoor), broad bean, Brussels sprout, cabbage, cauliflower, combining pea, field bean, lettuce (outdoor), mustard (spring), mustard (winter), oilseed rape (spring), oilseed rape (winter), sugar beet, swede, turnip and vining pea.
The best available application technique, which minimises off-target drift should be used to reduce effects on non-target insects or other arthropods when applying to apple, pear and raspberry (outdoor).

PESTS CONTROLLED

Please refer to Crop Specific Information section.
The possible development of pests resistant to Decis cannot be excluded or predicted.
Where such resistant strains occur, Decis is unlikely to give satisfactory control. When certain insects may develop resistance to Bayer products and since such circumstances are beyond our control, Bayer will be under no liability for any loss or damage whatsoever.
CROP SPECIFIC INFORMATION 
APPLICATION
Sprayers should be THOROUGHLY CLEANED before use and filters and jets checked for
damage and blockages.
200-1500 litres of water per hectare depending on crop and pest.
A pressure of 2-3 bar (30-40 psi) is recommended.
Apply as a MEDIUM quality spray (as defined by BCPC). Decis is not systemic and it is, therefore, important that the amount of water is sufficient to permit good spray coverage of the foliage, particularly in beans, peas, glasshouse crops and ornamentals. Use only nozzles designed and recommended for the volume to be applied.
For use in tractor mounted/trailed sprayer, orchard blast sprayer and knapsack sprayer.

Wheat and Barley
For the control of Barley Yellow Dwarf Virus (and some control of Opomyza).
Where BYDV has been a problem: For crops drilled before mid-September, spray when aphids are first found in the crop or in mid-October. If the crop is sprayed before early October, a second spray in early November may be beneficial. For crops drilled mid-September to early October, spray any time from mid-October to early November.
Where BYDV has not been a problem or if drilled after early October: Spray any time from late October to early November if aphids found or on specialist advice.
In mild winters further sprays may be needed
Dose: 200 ml/ha in 200 litres of water
For the control of Opomyza (yellow cereal fly). Apply at start of egg hatch (normally late January to February) or according to specialist advice. Crops most at risk are those drilled before mid-October in fields with a history of Opomyza.
Dose: 250 ml/ha in at least 200 litres of water.

Wheat, Barley and oats
For the control of aphids on ears.
Apply when two-thirds or more of heads are infested and numbers increasing (equivalent to 5 aphids per head).
Dose: 250 ml/ha in at least 200 litres of water.
Brussels sprouts, cabbage and cauliflower.
For the control of caterpillars (and some control of aphids and whitefly).
For Non-routine treatment; apply at the first stage of attack or as a preventative spray.
Dose: 300 ml/ha in at least 400 litres of water.
For pre-harvest clean-up, a reduced dose may be used when only short persistence of the product is required and applied 7 days prior to harvest.
Dose: 150 ml/ha in at least 400 litres of water.
For the control of brassica flea beetle (Phyllotreta spp.), apply when damage is first seen.
Repeat at 14-day intervals if necessary.
Dose: 300 ml/ha in 200-400 litres of water.

Peas and Bean (broad, and field)
For the control of pea and bean weevil, apply at first signs of adult damage (leaf notching). Repeat after 2-3 weeks if prolonged and heavy attack.
Dose: 300 ml/ha in 200-400 litres of water.
Pea midge; Apply sprays when local warnings indicate for control of pea midge and improvement in pod numbers. A second application may be necessary if the risk remains high.
Dose: 250 ml/ha in 200 - 400 litres of water.

Peas
For the control of pea moth (and some control of pea aphids). Apply according to the pea moth pheromone trapping system in conjunction with specialist advice.
Dose: 250 ml/ha in at least 400 litres of water.

Sugar Beet, swedes, turnips
For the control of flea beetle, apply at the first signs of damage.
Dose: 300 ml/ha in 200-400 litres of water.

Spring Oilseed Rape and Mustard
For the control of pollen beetle. Apply at green bud stage: If pollen beetle numbers are
at threshold levels. A second application may be necessary if pest attack is prolonged.
Dose: 300 ml/ha in at least 200 litres of water.
For the control of cabbage seed weevil, brassica pod midge. Apply at green to yellow bud stage if cabbage seed weevil numbers are at threshold levels. Repeat during flowering if pest attack is prolonged. Applications during flowering will also give control of brassica pod midge.
Dose: 300 ml/ha in at least 200 litres of water when applied during flowering.

Winter Oilseed Rape
For some control of Beet Western Yellows Virus (BWYV), Best results will be obtained by spraying at the 2-4 leaf stage, but spraying at 5-10 leaves can give good control.
Dose: 250 ml/ha in 200 litres of water.
For control of cabbage stem flea beetle and useful control, of rape winter stem weevil.
Apply when adults are seen to be causing leaf damage, usually late August to October.
Spray for flea beetle larvae once they can be found in leaf stalks, usually late October/ early November. A second spray may be necessary to control later hatches
Dose: 250 ml/ha in 200 litres of water.
For control of pollen beetle, Apply at green bud stage: If pollen beetle numbers are at threshold levels. A second application may be necessary if pest attack is prolonged.
Dose: 300 ml/ha in at least 200 litres of water.
For control of cabbage seed weevil, brassica pod midge, Decis can be applied at any time during the flowering period if cabbage seed weevil numbers are at threshold levels, but best results will be obtained from applications made at the end of flowering on the main raceme (GS 49), usually 75% petal fall. Later applications may not prove effective as Decis is primarily a contact insecticide. There is no spray threshold for brassica pod midge. Treatment decision should be based on previous local experience. Applications for seed weevil will also control brassica pod midge.
Dose: 300 ml/ha in at least 200 litres of water.

Lettuce (outdoor):
For the control of cutworms. Apply when pest first seen.
Dose: 250 ml/ha in at least 1000 litres of water.

MIXING AND APPLICATION
Prior to mixing EC formulations, such as Decis, it is particularly important to thoroughly
wash out the sprayer using a recommended detergent. Solvents in EC formulations can remove pesticides adhering to the tank and other parts of the sprayer.
Shake well before use. Add the required quantity immediately at the beginning of filling the spray tank with water. Keep the spray agitation in action and add the required quantity of water. Continue agitation until spraying is completed. After spraying, thoroughly wash out the spray tank.
