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

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.
Can be applied in frosty weather provided foliage is not covered with ice.

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 Protech 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: 330 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: 420 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: 420 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: 500 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: 250 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: 500 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: 500 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: 420 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: 420 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: 500 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: 500 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: 500 ml/ha in at least 200 litres of water when applied during flowering

Minor use recommendation
Based on limited data control of Brassica flea beetle Phyllotreta spp. would also be expected.
For the control of (Phyllotreta spp.), apply when damage is first seen.
Repeat at 14-day intervals if necessary
Dose: 500 ml/ha in 200-400 litres of water
This recommendation is based on limited effectiveness data.

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: 420 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: 420 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: 500 ml/ha in at least 200 litres of water.
For control of Cabbage seed weevil, brassica pod midge, Decis Protech 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 Protech 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: 500 ml/ha in at least 200 litres of water

Lettuce (outdoor):
For the control of Cutworms. Apply when pest first seen.
Dose: 420 ml/ha in at least 1000 litres of water.
