3 ACTIVE INGREDIENTS: Clopyralid 750g/kg.

Formulation: water dispersible granule.

4 CHEMICAL GROUP: I

Disrupter of plant cell growth.

5 RELATED HERBICIDES:

6 GENERAL DESCRIPTION:

A selective, translocated herbicide for the control of a range of broad-leaved weeds in cereals and Brassica crops.

7 APPLICATION METHODS AND TIPS:

Best results when applied to young actively growing plants in fine weather and rain follows a few days later.
Maximum tank storage time - 1 week.

8 WEATHER:

Rainfast in hours.
Frost effects:
Wind:
Inversions:
Temperature: Lontrel generally works more slowly under cool conditions.
Delta T and relative humidity: Avoid application when Delta T is greater than

9 ADJUVANTS:

Wetting agents:
Spray oils:

10 WATER QUALITY:

Hard water: There may be a slight loss of activity due to ionic bonding in very hard water.
Salty water:
Colloids: Some loss of activity as the amount of clay in the water increases. If it is difficult to see a coin on the bottom of a 10 litre bucket full of water then the water should be cleared or an alternate source found.
pH: Acidic water is usually OK. Highly alkaline water may cause loss of efficacy.
Tank life: 1 week.

11 COMPATIBILITY:

Trace elements.
Zinc sulphate and copper sulphate are antagonistic with clopyralid. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

If SWALLOWED - No treatment is usually required. Contact the Poisons Information Centre on 13 11 26.
If in EYES - Irrigate with plenty of water.
If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water.
If INHALED - Remove patient to fresh air.
Advice to doctor - Treat symptomatically.

27 ENVIRONMENTAL FATE:

It has a half life in soil of 12-70 days. Break down is by microbial action and is greatest in warm, moist, aerated soils with high organic matter.
It is not broken down in water by sunlight or hydrolysis.
It has an EPA classification for soil mobility that ranges from low to moderate.
Minimal leaching occurs and residues typically remain in the top 15 cm of soil
Ground water contamination
Replanting intervals
Accumulation in milk and tissues - does not accumulate

4. Poison Schedule : 5
5. Trade name : Lontrel 750 SG - DowElanco
6. Product Colour : Off white. Odourless.
7. Product Flammability : Non-flammable. Melts then decomposes at 280-290⁰C. Not explosive. Non oxidising.
8. Dangerous Goods Class : None allocated
9. Shelf Life : 5 years.
(When stored under ideal conditions)
10. Mixtures Compatibility : Do NOT mix with :- Products that are highly alkaline/acidic or that contain high ion contents.
11. Registered Crop(s) : see HerbiGuide
12. Effect of Soil Texture on Herbicide : Generally more mobile on soils of light texture and low organic matter.
13. Effect of Soil pH on Herbicide : Not available.
14. Effect of Soil Organic Matter on Herbicide : Generally more mobile on soils of light texture and low organic matter.
15. Mode of Action : Foliage translocation, some root absorption, Post-emergent.
16. Timing Application : see HerbiGuide
17. Rate Variations : see HerbiGuide
18. Rates Selection : Plant size generally determines the rate eg smaller plants, lower rates. Lower water rates - only when crop canopy is open and there is no shielding of weeds by the crop. Higher water rate in dense crops to achieve better penetration and coverage.
19. Crop Damage (Crop Tolerance) :
21. Effect on Legume Species : Both sub clover and medics do not tolerate higher rates of Lontrel (120 g/ha). 20 g/ha Lontrel + 1.0 L/ha MCPA is damaging to sub clover but only marginally more than 1.0 L/ha MCPA alone. Medics do not tolerate this mixture.
21c. Effect on Lucerne : Established plants are moderately to highly sensitive. Symptoms include yellowing, leaf cupping, retarding of growth and death.
22. Soil Moisture at Application : For optimal results plants should be actively growing.
23. Frost Effects :
25. Effect of Application Water Quality on Herbicide :
Saline Water - Lontrel is formulated to tolerate a range of hard and soft water conditions.
Soil Colloids - Clean water is preferred.
26. Recommended Water Volume : 50 - 150 L/ha boom, 200 - 250 L/ha hardhead thistle, 10 - 50 L/ha aircraft, crop and pasture.
27. Nozzle Type : 110⁰ flat fan, operating height 40 - 50 cm.
28. Recommended Nozzle Pressure : 200 - 350 kPa (28.6 - 50.8 psi).
30. Recommended Wetter : Not necessary for broadleaf weed control in cereals and canola. The addition of a wetting agent is recommended for some weeds
31. Other Additives : BP Ulvapron or spray oils in some forestry situations. Synertrol is NOT recommended. Uptake, D-C-Trate, D-C-Tron, Hasten and BS 1000 are compatible.
32. Rain Fastness : Minimum 3 hours.
33. Time Interval Before Effect is Noticed : Depends upon the rate of plant growth, varies from hours to days/weeks.
36. Withholding Period : 7 days to 12 weeks
37. Plant-Back Period : Susceptible crops such as Chickpeas, Clovers, Cotton, Faba Beans, Field Peas, fruit trees, Lentils, Lupins, Lucernes, Medics, ornamentals, Potatoes, Safflower, Tomatoes, vegetables, vines and Wattles- 9 months when treated at rates up to 120 g/ha and for twelve months with rates between 120 and 200 g/ha and two years where rates were greater than 200 g/ha. Field Peas are particularly sensitive and may require two years before they can be safely replanted in some situations.
38. Spray Tank Clean-Up : Wash out with hot soapy water or 1% solution of ammonia followed by several rinses with clean water.
39. Other Comments : Avoid spray drift onto susceptible crops or plants such as lupins, faba beans, field peas, vines, fruit trees, vegetables and ornamentals. The rate of clopyralid decay is affected by both soil texture and rainfall in the period following application. Clopyralid residues in canola or cereal stubble may cause damage to susceptible crops grown in rotation the following season. These crops include: field peas, faba beans, lupins, chickpeas, and sub clover or medic pastures (volunteer or undersown). Accordingly rotations should be planned to ensure these crops/pastures will not be grown in the year following the use of Lontrel in cereal or canola crops. Corrosive to aluminium, steel and tin plate.
