DIRECTIONS FOR USE

IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

Restrictions and warnings
Restrictions
RAPSAN 500 SC is suitable for use on all soil types as defi ned in the Soil Texture (85) System, except sands and very light soils and soils containing more than 10% organic matter.
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 RAPSAN 500 SC 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 RAPSAN 500 SC. Ensure that transplants are correctly planted with the roots well covered. Loose and puffy seedbeds must be consolidated before treatment.
Warnings
1. A reduction in crop vigour, weed control and possibly plant stand may occur with excessive rainfall shortly after application. If heavy irrigation is planned after transplanting, apply RAPSAN 500 SC after irrigating. Where a crop check has occurred this usually grows out after a few weeks and yields are normally unaffected.
2. Do not apply RAPSAN 500 SC to soils with a compaction layer or to poorly drained soils, since damage can occur under waterlogged conditions.
3. If RAPSAN 500 SC is applied onto a dry soil surface it will only be effective after rainfall has occurred. Light (10 mm at any one time) irrigation will help to ensure herbicidal activity. Post-emergence weed control is also dependent on adequate moisture.
4. On brashy and stony soils, RAPSAN 500 SC may cause some reduction in crop vigour and/or plant stand, due to the chemical moving down to the rooting zone too rapidly.
5. Do not overlap spray swaths, particularly on the headlands.
6. Do not treat crops, which are suffering from wilting, pests or diseases or badly planted transplants.
7. When used alone RAPSAN 500 SC has very little dewaxing activity. However, under frosty conditions a transient scorch may sometimes occur. Do not use
RAPSAN 500 SC in tank mixtures under frosty conditions.

Important notes
1. Avoid spray drift on to neighbouring crops.
2. Do not use fi lters fi ner than 50 mesh.
3. WASH EQUIPMENT thoroughly immediately after use. Fill the tank with clean water and leave overnight. Spray out before storage or using other products.
Traces of the product may cause damage to susceptible crops sprayed later.

Time of application
RAPSAN 500 SC may be applied pre-emergence or post-emergence, depending on soil type, the seedbed conditions and weed spectrum, see below.
Pre-emergence use
On medium and heavy soils where seedbeds are moist, fi rm and free from clods,
RAPSAN 500 SC 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 the full rate pre-emergence recommendation when any of the following conditions apply:
• When heavy rain is forecast.
• Dry cloddy seedbeds.
• Do not use on broadcast or late drilled crops
• Stony soils i.e. stones, fl ints or chalk, readily visible on the soil surface

Early post-emergence use
RAPSAN 500 SC can be used on light, medium or heavy soils post-emergence, once the majority of the crop has reached the fully expanded cotyledon stage, providing weeds are not beyond their maximum susceptible growth stage (see weed susceptibility section and note moisture requirement).
Post-emergence application of RAPSAN 500 SC is recommended if:
• Seedbed conditions are not ideal for the pre-emergence use.
• The seed is not covered with 15 mm of soil (as with broadcast crops).
• RAPSAN 500 SC could not be applied before the crop seed chits.
• Light soils, or all recommended soils which are stony, brashy or gravely, are to be treated, particularly if heavy rainfall has been forecast for the period following drilling.
• Late drilled crops are to be treated.
Rates of application for pre- or post-emergence
Apply 1.5 litres RAPSAN 500 SC per hectare, pre- or post-emergence.

Water volume
When applying RAPSAN 500 SC pre-emergence in tank mixture or whenever applying RAPSAN 500 SC post-emergence, use a minimum water volume of 220 litres per hectare.
RAPSAN 500 SC can be applied in water volumes of 100 litres per hectare when used pre-emergence, but should not be used on poor seedbeds nor in tank mixture with other products at this water volume. When using this low water volume, fan or hollow cone nozzles designed to operate at normal pressure, 2-3 bar or low pressure fan nozzles designed to operate at around 1 bar, producing a coarser spray, may be used.
