PRODUCT LABEL

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

RESTRICTIONS
Do not apply to forage maize and grain maize grown for seed production.

Do not apply with organo-phosphate insecticides.

Do not use during periods of frosty weather, when frost is imminent, or onto crops under stress from frost, waterlogging, insect attack or drought.

Special care should be taken to avoid damage by drift to broad-leaved plants outside the target area or land intended for cropping.

Do not apply JESTER in sequence or in tank mix with a product containing any other sulfonyl-urea.

Ensure spraying equipment is thoroughly washed out according to specific instructions after use. Do not allow washings-out to drain onto land intended for cropping or growing crops.

WEEDS CONTROLLED
JESTER is a selective herbicide containing prosulfuron, a sulfonyl-urea herbicide, and bromoxynil as the phenol. Prosulfuron has contact and residual activity. Bromoxynil is a contact herbicide.

JESTER is used post-emergence of the crop to control a wide range of annual broad-leaved weeds in maize which are controlled up to the 4 true leaf stage.

A dose of 0.4 kg/ha may provide acceptable levels of control of annual mercury, black nightshade, charlock, common chickweed, common field speedwell, fat hen, field pennycress, hempnettle and common orache up to the four leaf stage. Where these weeds are encountered in mixed populations with other label weeds always use 0.5 kg/ha.

* Qualified recommendation, based on limited data
** Add a non-ionic surfactant adjuvant that is not an organosilicone in accordance with the manufacturer’s instructions CROP SPECIFIC INFORMATION
Crops
Apply to forage maize and grain maize crops, but excluding crops grown for seed production.

On crops intended for processing, consult processor before use.

Timing
Application should be made post-emergence up to the six leaf unfolded stage of the crop.

To avoid scorch, apply JESTER under cool conditions. If the weather during application turns hot, spray in the evening when temperatures have fallen.

Rates of use
Apply JESTER at 0.5 kg product per hectare. Add a non-ionic surfactant adjuvant that is not an organosilicone in accordance with the manufacturer’s instructions. Please refer to Syngenta literature for lists of authorised adjuvants. Always use adjuvants at their recommended rates.

FOLLOWING CROPS
Succeeding-crop Restrictions
Following normal harvest, sow any of the listed crops:

Winter or spring cereals Spring-sown peas and beans
Winter beans Spring-sown oilseed rape*

For crops marked (*), it is good practice for successful crop establishment to mould-board plough to a depth of 20 cms prior to drilling.

Persistence of JESTER is increased under prolonged dry conditions.

Resistance Strategy
Do not rely on sulfonyl-urea herbicides as the sole means of weed control. The use of mixtures or sequences with other herbicides with different modes of action, active against the same target weeds, is desirable. This will minimise the possible development of resistant weeds. Contact your distributor or Syngenta Crop Protection UK Limited for further information.

MIXING AND SPRAYING
Spray Volume
Use a water volume of 200–400 litres per hectare.

Spray Nozzles
A MEDIUM spray quality is preferred for application of JESTER (see BCPC guidelines).

A spray pressure of 2–3 bar is recommended.

Mixing and spraying
Make sure the sprayer is set to give an even application at the correct volume.

Dry Mixing – Sprayers with Induction Hoppers
Fill sprayer to 15% of tank capacity with water and start agitation. Pour JESTER into the induction hopper and open valve in bottom of hopper to suck the granules into the circulating spray mix. Continue adding JESTER until loading is complete. Wash down any granules on the hopper wall and close valve. Add the non-ionic surfactant and continue agitation whilst adding the rest of the water.

Note for Old Sprayers with Indirect Venturi Induction Hoppers
In the unlikely event of problems occurring during dry induction of the granules (blocked venturi), open the rinse ring and add water to the hopper. As soon as product induction continues, carry on adding product until the required amount is reached.

Sprayers without Induction Hoppers
Fill the sprayer with a minimum of 15 cms of water in the bottom and agitate vigorously. Pour JESTER through the sprayer lid. Add the non-ionic surfactant and continue agitation whilst adding the rest of the water.

Agitate the mixture thoroughly before use and continue agitation during spraying.

Take particular care to avoid overlapping spray swathes.

Thoroughly wash all spray and measuring equipment with water according to the directions below immediately after use.

Washing-out Instructions
To avoid subsequent injury to crops, immediately after spraying thoroughly clean the application equipment and protective clothing. Ensure that all traces of product are removed. The following recommendations are to be strictly followed:

1. Drain spray system completely. Rinse tank, spray boom and nozzles with clean water for several minutes and spray out.

2. Half fill the spray tank with clean water and add to it sodium hypochlorite (5.2%) (commercial chlorine bleach) at a dose of 1 litre for every 200 litres of full spray tank capacity and continue filling with clean water until sprayer is completely full. Agitate for 15 minutes and spray out cleaning solution through spray nozzles.

3. To remove traces of chlorine bleach, rinse the tank thoroughly with clean water and flush out through hoses and boom.

4. Nozzles and filters should be removed and cleaned separately along with protective equipment.

PROTECT FROM FROST


SAFETY PRECAUTIONS
(a) Operator protection
Engineering control of operator exposure must be used where reasonably practicable in addition to the following Personal Protective Equipment.
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS), SUITABLE PROTECTIVE GLOVES AND SUITABLE RESPIRATORY PROTECTIVE EQUIPMENT (FFP2) when handling the concentrate.
WEAR SUITABLE PROTECTIVE GLOVES when handling the spray boom or adjusting nozzles.
However, engineering controls may replace personal protective equipment if a COSHH assessment shows that they provide an equal or higher standard of protection.

volumes.
AVOID ALL CONTACT WITH EYES. IN CASE OF CONTACT WITH EYES, RINSE IMMEDIATELY with plenty of water and seek medical advice.
