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 treat with SAMSON EXTRA 6% once a soil insecticide based on an organophosphate like phorate has been applied.
• Do not mix with foliar or liquid fertilisers.
• Under certain conditions, some transient yellowing and/or crop stunting and/or loss of vigour can be seen from 1 to 2 weeks after treatment (2–8 leaves of maize). This is quickly outgrown and no yield effect has been shown.
• Applications should not be made to maize crops that are under stress, as this may lead to incidences of more persistent crop damage. Apply product at the recommended dose to a healthy crop.
• Strains of some annual weeds (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 advisor or product manufacturer.
• Avoid the use of SAMSON EXTRA 6%, or any other ALS inhibitor herbicide, as a sole means of grass and broad-leaved weed control in successive crops.
• This product should not be used to control ‘light infestations’ of weeds.
• Avoid overlapping spray swaths, as considerable crop damage may occur which may not grow out and could lead to yield reductions.
• Some flower deformation may be seen on particular sensitive varieties e.g. Abraxas, Fjord and Rival.
• Due to its high level of activity, care must be taken to avoid damage by spray drift onto plants outside the target area.

WEEDS CONTROLLED
SAMSON EXTRA 6% can be used to control the following weeds in maize.

Suppression of Common Couch (Elytrigia repens)
See specific information regarding the control of this weed under ‘Timing and Rates of Use’.

Control of Annual Grass:

COMMON NAME: Annual meadow-grass
LATIN NAME: Poa annua
DOSE RATE (litres product/ha): 0.5

Limited data indicate 0.75 l/ha SAMSON EXTRA 6% can control field pansy, groundsel and annual mercury.
For moderately resistant weeds, the effectiveness is generally 60–80%.
For moderately susceptible weeds, the effectiveness is generally 70–90%.
For susceptible weeds, the effectiveness is generally 80–100%.

Weed Resistance
This product contains nicosulfuron which is an ALS inhibitor, also classified by the HRAC as ‘Group B’.
Use only as part of a resistance strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grassweed control.
There is potential for resistance to develop to SAMSON EXTRA 6% if the product is used alone in monoculture over a number of years. SAMSON EXTRA 6% should be used in mixture or in sequence with herbicides with other modes of action, particularly in continuous maize, as part of a weed resistance management plan. Crop rotation, in which using herbicides with different modes of action, can be practised as an alternative to reduce risk of development of resistance.

CROP SPECIFIC INFORMATION
Timing and Rates of Use
Suppression of Common Couch (Elytrigia repens):
Use: When used to control other weeds, applying the 0.75 l/ha dose of SAMSON EXTRA 6% at the 4–6 leaf stage of the couch will provide a useful level of control of Common Couch. The efficacy is generally above 75%. Useful level of control of top growth will be seen in the year of application, but reduction of growth in the following year has not been investigated.

Control of Annual Grass:
Use: Apply 0.5 l/ha in 200 l/ha of water at 2-8 leaf stage of the crop, 2 leaves to early tillering of the weed.

Control of Broad-leaved Weeds:
Use: Apply between 0.67 l/ha and 0.75 l/ha in 200 l/ha of water at 2-8 leaf stage of the crop, 2 leaves to 6 leaves of the weeds. WARNING: In order to give maximum control of Fat hen the weeds must be growing well and not under any form of stress.

FOLLOWING CROPS
In normal crop rotation, after ploughing, winter wheat, winter barley, winter rye, and triticale can be sown. All other crops can be sown in the following spring. In case of crop failure, maize can be sown after ploughing.

MIXING AND SPRAYING
Preparation of the spray solution
Shake the SAMSON EXTRA 6% container thoroughly. Half fill the spray tank with clean water and begin agitation. Add the required quantity of SAMSON EXTRA 6% to the tank and complete filling. Continue agitation until spraying is completed.

Application
Application of SAMSON EXTRA 6% will be achieved by using conventional ground spraying equipment at water volumes of 200-400 l/ha.

Do not spray SAMSON EXTRA 6% if any rainfall is expected in the next 6 hours.

Tank cleaning procedure
The following cleaning procedure is recommended:
1. Drain tank completely then flush tank, boom and hoses with clean water. Drain again.
2. Half fill the tank with clean water and add an ammonia based solution (All Clear Extra – 1.0 litre per 200 litres water). Flush through boom and hoses and then allow to stand for 10 minutes with agitation. Drain completely.
3. To remove traces of detergent, rinse the tank with clean water and flush through booms and hoses.
4. Repeat step 2.
5. Nozzles and filters must be removed and cleaned separately with the detergent solution at the same concentration as above.
6. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.

SOIL CONDITIONS
SAMSON EXTRA 6% can be used on all soils (light, medium and heavy soils) and is unaffected by high organic matter.

STORAGE:
Store the container at room or cool temperatures.

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 AND SUITABLE PROTECTIVE GLOVES) when handling the concentrate.
However engineering controls may replace personal protective equipment if a COSHH assessment shows they provide an equal or higher standard of protection
WASH ALL PROTECTIVE CLOTHING thoroughly after use, especially the insides of gloves.
AVOID ALL CONTACT WITH SKIN.
WASH HANDS AND EXPOSED SKIN before meals and after work.

(b) Environmental protection
DO NOT ALLOW DIRECT SPRAY from horizontal boom sprayers to fall within 5m of the top of the bank of a static or flowing waterbody, unless a Local Environmental Risk Assessment for Pesticide (LERAP) permits a narrower buffer zone, or within 1m of the top of a ditch which is dry at the time of application.

DO NOT ALLOW DIRECT SPRAY from hand-held sprayers to fall within 1m of the top of the bank of a static or flowing waterbody. Aim spray away from water.
This product qualifies for inclusion within the Local Environmental Risk Assessment for Pesticides (LERAP) scheme. Before each spraying operation from a horizontal boom sprayer, either a LERAP must be carried out in accordance with CRD’s published guidance or the statutory buffer zone must be observed. The results of the LERAP must be recorded and kept available for inspection for three years.
Do not contaminate water with the product or its container. Do not clean application equipment near surface water. Avoid contamination via drains from farmyards or roads.

(c) Storage and disposal
RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of safely.
