GENERAL INFORMATION
REGLONE is a non-residual fast acting herbicide active on green plant tissues only. It is particularly effective in controlling most annual and many perennial broadleaf weeds, but clover will recover quickly. REGLONE is inactivated on contact with soil.
BEWARE: Apply this product carefully. Spray drift may cause serious damage to other desirable plants.

DIRECTIONS FOR USE

POTATOES

HAULM DESTRUCTION
Situation: 
Very dense haulms
Rate: 
Two applications 7 to 10 days apart in 600 to 1100 litres of water/ha. 1st application 3 to 4 litres/ha . 2nd application 1.5 to 3 litres/ha OR 4 to 6 litres in 900 to1100 litres of water/ha as a single application
Critical Comments: 
As a general guide REGLONE should be applied to the crop about 14 days before proposed harvesting date. Leaf kill following REGLONE treatment is rapid and usually complete after four days, but stem kill will take up to 14 days, depending on such factors as density of haulms and weather conditions following spraying (kill is more rapid during bright weather). Under conditions of hardened top growth, the split application is preferable for best results.

Situation: Moderate to sparse haulms
Rate:
3 to 4 litres in 600 to 1100 litres of water/ha
Critical Comments: 
Single application satisfactory.

PRE-DIGGING WEED CONTROL
Situation: 
Broadleaf weeds only
Rate: 
3 to 4 litres in 350 to 450 litres of water/ha
Critical Comments:
 Where digging has been postponed for an extended period, weed growth may need to be removed to provide a clean harvest. A non-ionic wetting agent MUST be added at label rates. 

Situation: Broadleaf and Grass weeds
Rate: 
1.5 to 2 litres GRAMOXONE plus 1.5 to 2 litres REGLONE in 350 to 450 litres of water/ha
Critical Comments: 
A non-ionic wetting agent MUST be added at label rates.

Notes
- REGLONE is NOT recommended for use on the Rua variety.
- The rate of REGLONE necessary will be governed by the vigour and density of the haulm at the time desiccation is required. Potato varieties with vigorous, dense tops such as Sebago and Tahi may require two applications applied 7 to 10 days apart to ensure complete spray penetration.
- Avoid application of REGLONE to potatoes when the haulms are heavily laden with early morning dew. This can cause the chemical to be shed, leading to poor leaf desiccation. During prolonged dry periods the use of any haulm destroyer may damage the tubers. DO NOT spray when the soil is very dry.
- DO NOT use a wetting agent with REGLONE for potato haulm applications.

BARLEY, WHEAT
Use: Pre-harvest crop and weed desiccation
Rate: Aerial: apply 3 to 4 litres in a minimum of 350 litres of water /ha (Non-ionic wetting agent MUST be used at label rates)
Critical Comments: To remove weeds, hasten maturity and reduce the risk of harvesting losses from adverse weather. Weeds growing in a fully matured crop may be desiccated to allow clean bulk harvesting.

HORMONE-HAZZARDOUS AREAS
Use: Gorse
Rate: 700 mL plus 200 mLof a non-ionic wetting agent per 100 litres of water
Critical Comments: Where risk of damage to sensitive crops precludes the use of hormone sprays REGLONE is an alternative. Thorough coverage is essential.

GREEN BEANS, LENTILS, PEAS, SOYA BEANS
Use: As a desiccant and also to remove weeds and prevent secondary crop growth
Rate: 3 to 4 litres in 300 to 350 litres of water/ha. Aerial: a minimum of 4 litres in 350 litres of water/ha. (Non-ionic wetting agent MUST be used at label rates)
Critical Comments: Apply 7 days prior to harvesting, as soon as the seeds are fully developed and the pods are drying.

LUCERNE, RED CLOVER, WHITE CLOVER
Use: Dessication
Rate: 3 litres in 300 to 350 litres of water/ha. (Non-ionic wetting agent MUST be used at label rates)
Critical Comments: As soon as the seed from the main flowering has matured, further crop growth can be halted in preparation for harvest.

AQUATIC WEED CONTROL

LAKES AND PONDS (still water)
Weeds controlled: Canadian Pondweed (Elodea canadensis), Lagarosiphon (Lagarosiphon major), Pondweeds (Potamogeton crispus and Potamogeton ochreatus), Hornwort (Ceratophyllum demersum)
Rate: Boom: 30 litres per hectare Handgun: 2 litres /100 litres of water, applying 1.5 litres of spray mix / 10 square metres
Critical comments: In boom application from aircraft or boat, use sufficient water to obtain even coverage. Alternatively, apply below surface using trailing nozzles behind a mobile platform.

DRAINS AND WATERWAYS (flowing water)
Weeds controlled: Canadian Pondweed (Elodea canadensis), Lagarosiphon (Lagarosiphon major), Pondweeds (Potamogeton crispus and Potamogeton ochreatus), Hornwort (Ceratophyllum demersum)
Rate: 30 litres per hectare
Critical comments: Apply by trailing nozzles below surface behind a mobile platform, or broadcast spraying (travelling upstream) is recommended. DO NOT treat where water is flowing at more than 1 km per hour (30 cm/sec).

 WARNING
- Injections from a fixed point MUST NOT be made.
- When applied to any natural water, treated water MUST NOT be bathed in, used for human consumption, fish farming or livestock watering for 24 hours after application.
- In a lake or any standing water, to maintain adequate oxygen supply to fish, NOT more than one quarter of the area should be treated at one time.
- Treated still water should NOT be used for overhead irrigation, until 10 days after treatment. However, water from a flowing water course may be used 24 hours after treatment.
- Consult the appropriate Regional Council before discharging REGLONE into natural water.

NOTES
- REGLONE is NOT effective in turbulent, muddy water or where suspended organic matter is above 1 ppm.
- Treatment is best when water levels are at their lowest and temperatures at their highest.
- REGLONE at the recommended rates is not toxic to fish.
- A non-ionic wetting agent should be added to REGLONE at label rates for aerial application, but it is not required when using the injection technique.

MIXING
Use clean water only (dirty water will interfere with the action of the chemical). Partly fill spray tank with water, add the REGLONE and add a non-ionic wetting agent (where recommended), mix, then top up with water to required volume.

APPLICATION
Conventional spray equipment may be used for application. In all cases complete coverage is essential. For boom spraying use a minimum of 300 litres of water per hectare, but up to 1100 litres per hectare may be necessary when using for "Potato Haulm Destruction" (refer to specific directions). After use, wash out all spraying gear with 2 or 3 changes of clean water.

WETTING AGENT
REGLONE contains no wetting agent and a non-ionic wetting agent MUST be added to the spray mixture at label rates, with the exception of the following uses:
(a) Potato Haulm Destruction - DO NOT add a wetting agent.
(b) Submerged Aquatic Weed Control (Injection Method) - DO NOT add a wetting agent.
