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.

8 WEATHER:

Rainfast in hours.

Frost effects:

Wind:

Inversions:

Temperature:

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.

Half life in soil: 12-70 days.

Half life in water: days at pH5 and 35 C.

It has an EPA classification for soil mobility that ranges from low to moderate.

2. Concentration of Active Constituent : 300 g/L

3. Formulation : Aqueous Concentrate

4. Poison Schedule : 5

5. Trade name : Lontrel L - DowElanco

6. Product Colour : Straw colour.

7. Product Flammability : Non-flammable.

8. Dangerous Goods Class :

9. Shelf Life : 24 months

(When stored under ideal conditions- refer Page 4)

10. Mixtures Compatibility : 2,4-D, Glean (chlorsulfuron), MCPA, Aryloxyphenoxy grass killers eg Verdict.

Do NOT mix with :- Products that are highly alkaline/acidic or that contain high ion contents.

11. Registered Crop(s) : Wheat, Barley, Oats, Triticale, Canola, Pasture.

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 : Cereals - from 4 to 5 leaf stage.

17. Rate Variations : 50 mL - 4.0 L/ha

18. Rates Selection : Plant size generally determines the rate eg smaller plants, lower rates. 50 - 70 mL/ha should only be used in mixture with MCPA amine or LVE Ester. 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) : Wheat, Canola at 4-5 leaf stage. Clover and Medics - Nil tolerance.

21. Effect on Legume Species : Both sub clover and medics do not tolerate higher rates of Lontrel (300 mL/ha). 50 mL 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 : Lontrel L generally works more slowly under cool conditions.

25. Effect of Application Water Quality on Herbicide :

Saline Water - Lontrel L 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 : 110o 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 oilseed rape (canola). The addition of a wetting agent is recommended for treatment of Hardhead and Californian thistles in pasture and fallow.

31. Other Additives : BP Ulvapron (Only in 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 : Do not graze, cut or harvest:-Pasture or cereals for 7 days, if sprayed with rates of 300 mL/ha or less, Pasture or cereals for 28 days, when treated at rates in excess of 300 mL/ha, Cereals for 70 days, when treated at rates in excess of 300 mL/ha, Canola for 84 days after application.

37. Plant-Back Period : Lupins, Field Peas - 9 months when treated at rates of 300 - 500 mL/ha. Clovers, Medics - Minimum 12 months when treated at rates of 2 - 4 L/ha. (See above for updated data)

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 L in cereal or canola crops. Corrosive to aluminium, steel and tin plate.
