Beware: Apply this product carefully. Spray drift may cause serious damage to desirable plants. Ensure compliance with relevant regional air management plans. A strategy to minimise spray drift should be employed at all times when applying spray near aquatic environments.

IMPORTANT: 
Injury to or loss of desirable trees or other plants may result from failure to observe the following. DO NOT apply or drain or flush equipment on or near desirable trees or other plants, or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots. DO NOT use on lawns, walks, driveways, tennis courts or similar areas. Application to drains and irrigation channels must only be made when these waterways are dry and at least two months is allowed to elapse before the channels are used for carrying water. Prevent drift of dry powder or spray to desirable plants. Keep from contact with fertilizers, insecticides, fungicides and seeds.

GENERAL INFORMATION 
ADAMA Metsulfuron Herbicide is a dry flowable granule to be mixed in water and applied as a foliar spray for control of certain scrub weeds in pasture and waste areas. It is non-corrosive, non-flammable and non-volatile. Best results are obtained when ADAMA Metsulfuron Herbicide is applied to actively growing weeds during late spring to late autumn. Weeds not controlled include – black nightshade, woolly nightshade, boxthorn, browntop, cocksfoot, paspalum, Kikuyu grass, Indian doab, couch and pampas grass.

MIXING 
Use the graduated measuring cylinder provided, measure the correct amount of ADAMA Metsulfuron Herbicide required for the area to be sprayed and add to the required volume of water. Continuous agitation is required to keep the product in suspension.

ADDITIVES
Apply an organo-silicone penetrant such as Input® , Pulse® , Freeway® or Boost at the rate of 100 mL. per 100 litres of spray mixture where indicated under recommendations for specific weeds in the table below except for aerial or boom application to gorse and application to seedling gorse where the rate required is 400mL per 100 litres of spray mixture.

MARKER DYES
ADAMA Metsulfuron Herbicide is compatible with commonly used marker dyes but tank mixtures including marker dyes based on acetic acid should be used within 24 hours.

APPLICATION 
Handgun Spraying: Apply to achieve full coverage of foliage and stems and penetration into bushes. Use pressures of 1,000 – 2,000 kPa preferably through a No. 4 or No. 6 spray tip. Apply no less than 1,000 litres of spray per hectare. The amount of spray required will vary with the height, density and type of scrub.

Knapsack Spraying: Use a hand knapsack only on small bushes where full coverage of foliage and stems can be achieved.

Mist blower: Obtain good coverage of foliage and stems and penetration into bushes. For U.L.V. attachments use the largest setting. Booklet Metsulfuron Final label 4 Feb 09 Page 7 of 9 HSNO classifications 6.3B, 6.4A, 9.1A, 9.2A

Aerial Application
STANDARD BOOM SYSTEM: Apply no less than 200-300 litres of water per hectare as two overlapping passes of 100-150 litres per hectare. 
FOAMING NOZZLE SYSTEM: Apply in a minimum of 230 litres of water per hectare as two overlapping passes of 115 litres per hectare. 
AERIAL APPLICATION IS RECOMMENDED FOR USE IN NON-AGRICULTURAL AREAS ONLY.

Carpet Roller/Wiper Application: For control of ragwort, buttercup, Scotch, Californian, winged and nodding thistles. Graze pasture to maximise height difference between pasture and weeds. Pre-mix 1g ADAMA Metsulfuron Herbicide per litre of water and ensure roller is wet before starting off. In heavy weed infestations a second pass in the opposite direction will provide best results. Keep the wiping area moist and free of debris. To prevent localised pasture damage avoid dripping from the roller/wiper.

Stump Swabbing: Gorse, barberry, mix 5g ADAMA Metsulfuron Herbicide per litre of water and using a paintbrush or knapsack sprayer, apply liberally to the freshly cut surface and stem to ground level.

Stem Injection: Poplars, willows, privet and pines. Mix 20g of ADAMA Metsulfuron Herbicide per litre of water and inject 2mL of solution into cuts or holes made at 10 cm intervals around the trunk of the tree. Control of larger willow trees may be variable.

Forestry: Radiata Pine (Only): Use only as a pre-plant treatment. Apply 170g ADAMA Metsulfuron Herbicide per hectare for control of bracken, blackberry and seedling gorse. DO NOT plant trees within 2 months of spraying.

Whenever possible use ground application equipment. Crushing, slashing or burning of treated bushes is recommended and these operations should be carried out whenever canes are brittle enough. Intensive stocking (sheep or goats) and oversowing of treated areas will minimise amount of re-growth. There may be some re-growth requiring follow-up treatment two years after spraying

RE-ESTABLISHMENT OF PASTURE:
ADAMA Metsulfuron Herbicide is extremely injurious to clovers and ryegrass. Residues of ADAMA Metsulfuron Herbicide in the soil may prevent early re-establishment of clovers and ryegrass after treatment. The period that residues persist in the soil will vary according to site conditions such as climate, soil and the rate used. A minimum period of three months should elapse before oversowing treated areas with clover or ryegrass. It is suggested that small areas be oversown 1-2 months prior to the planned time for sowing to check for possible harmful residues. Where quick cover of vegetation is required a resistant grass such as browntop or cocksfoot can be oversown.
