DIRECTIONS FOR USE
Butisan S is a residual herbicide which can be used in all varieties of winter and spring sown oilseed rape, swedes, turnips, cabbages, Brussels sprouts, cauliflowers, broccoli and calabrese. It may also be used in some ornamentals, hardy nursery stock, nursery fruit trees, farm woodland and commercial forestry.
Butisan S is suitable for use on all soil types as defined in the Soil Texture (85) System, except sands and very light soils and soils containing more than 10% organic matter.

Restrictions/Warnings
Herbicidal activity is dependent upon root uptake.
Useful weed control can be obtained on soils with an organic matter higher than 10% but it may decrease as the percentage of organic matter increases appreciably.
With drilled crops, when applying Butisan S pre-emergence, it is important for crop safety to ensure physical separation of the herbicide from the seed. This is achieved by ensuring that the seed is well covered with soil, to a depth of 15 mm. With direct drilled crops, harrow across slits to cover the seed before spraying Butisan S.
Ensure that transplants are correctly planted with the roots well covered. Loose and puffy seedbeds must be consolidated before treatment.
Weed Control
Resistance
Strains of some annual grasses (e.g. black-grass, wild-oats, and Italian rye grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
Crops
Winter oilseed rape
Time of Application
Butisan S may be applied pre- or post-emergence of the crop, depending on soil type, the seedbed conditions and weed spectrum, see Section 2.1. Do not use later than the end of January.
Pre-emergence use:
On medium and heavy soils where seedbeds are moist, firm and free from clods,
Butisan S should be applied from drilling up until the crop seed chits. In warm soils, this may occur within 48 hours of drilling.
DO NOT USE on broadcast crops.

Rate of application
Apply 1.5 litres Butisan S per hectare, pre or post-emergence of the crop.
Water volume
When applying Butisan S pre-emergence in tank mixture or whenever applying Butisan S post-emergence, use a minimum water volume of 220 litres per hectare.
Butisan S can be applied in water volumes of 100 litres per hectare when used pre-emergence, but should not be used on poor seed beds nor in tank mixture with other products at this water volume. When using this reduced water volume nozzles designed to produce a coarser spray may be used.
Apply 1.5 litres Butisan S per hectare, pre or post-emergence of the crop.

Swedes and turnips
Apply 1.5 litres Butisan S per hectare, pre-emergence of the crop.
Application
Butisan S should be applied to seedbeds that are firm, moist and free from clods before the crop seed chits.
This may occur within 48 hours of drilling in warm soils. DO NOT treat if a period of heavy rain is forecast as heavy rain before emergence may reduce crop stand. The latest time of application of Butisan S is pre-emergence in swedes and turnips.
Water volume:
Butisan S should be applied in 220–450 litres of water per hectare. Use the higher water volume where seedbeds are not ideal (e.g. slightly cloddy).

Spring oilseed rape
An application of 1.5 l/ha Butisan S is recommended in this crop.
An application of 1.5 l/ha Butisan S is recommended in this crop.
Application
Butisan S should be applied to seedbeds that are firm, moist and free from clods before the crop seed chits.
This may occur within 48 hours of drilling in warm soils. DO NOT treat if a period of heavy rain is forecast as heavy rain before emergence may reduce crop stand. As an alternative, for spring oilseed rape apply once the crop has two fully expanded cotyledons but before weeds emerge. Broadcast crops must ONLY be treated post-emergence and this is the preferred timing for all crops grown on light, brashy, stony or gravelly soils.
Do not apply after the crop has 10 true leaves.

Transplanted brassicae
An application of 1.5 litres per hectare Butisan S is recommended in these crops. Application
The latest time of application of Butisan S is 6 weeks before harvest in transplanted brassicae.
When treating transplants, ensure that the roots are well covered with soil and that the plants are adequately hardened off and established prior to treatment. If necessary, use irrigation to help establish the plants and raise soil moisture before treatment with Butisan S. Avoid spraying transplants when very warm days and cool nights are expected.
Modular or block-raised transplants
can be particularly sensitive to herbicide damage because they are often both soft and immature. It is essential that the directions concerning transplants are followed in full and it is advisable to only treat a small area in the first instance.
Water volume
Butisan S should be applied in 220 450 litres of water per hectare. Use the higher water volume where seedbeds are not ideal (e.g. slightly cloddy).
Direct drilled brassicae
To prolong weed control in direct drilled cabbages, Brussels sprouts, cauliflower, broccoli or calabrese, one application of Butisan S can be made post-emergence of the crop following the use of an alternative pre-emergence treatment.
Application
Apply Butisan S after the crops have 3–4 true leaves but before weed emergence. Do not treat crops within 6 weeks of harvesting.
Rate
Apply 1.5 litres Butisan S in 220–450 litres of water per hectare.
Following Crops
Any crop can follow normally harvested winter oilseed rape treated with Butisan S and ploughing is not essential before sowing the following cereal crop.
In the event of a crop failing in the autumn or winter, then several crops can be drilled after the use of Butisan S alone as follows:
Redrilling the same autumn
Winter Wheat (excluding Durum) or Winter Barley: After ploughing to a depth of at least 150 mm.
Redrilling the following spring
After ploughing, the following crops can be sown:
CEREALS (excluding Durum wheat)
TRANSPLANTED OR DIRECT DRILLED BRASSICAE
FIELD BEANS
PEAS
POTATOES and MAIZE
LINSEED
Following spring applications to swedes, turnips or brassicae, crops particularly sensitive to Butisan S, e.g.
carrots, parsnips and lettuce, should not be planted within 5 months of treatment. Plough to a depth of at least 150 mm before sowing or planting any succeeding crop.
Where crops follow use in ornamental trees, ornamental shrubs and nursery fruit trees, follow the instructions given above for Butisan S alone.
Mixing and Spraying
SHAKE WELL BEFORE USE. Half fill the spray tank with clean water and start the agitation. Pour in the required amount of Butisan S. Add the remainder of the water and continue agitation until spraying is completed.
Rinse empty containers thoroughly, and add rinsings to the sprayer tank.
When tank mixes are to be used, each product should be added separately to the spray tank, taking due note of any instructions given as to the order of mixing.
Apply as a MEDIUM spray, as defined by BCPC.
