Lontrel^™ XC

Field sprayer application Do not apply during periods of dead calm. Avoid application of this product when winds are gusty. Do not apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification.  Boom height must be 60 cm or less above the crop or ground. Do not apply by air.
To reduce spray drift, use nozzles that deliver higher volumes and coarser droplets. Use low pressures (200 to 275 kPa). Use 100 to 200 L/ha of spray solution. Spray when the wind velocity is 15 km/h or less.

Each case of Lontrel XC herbicide contains 4 x 2.67 L jugs.

Lontrel™ XC has a wide range of rates from 69 mL to 202 mL/acre. Use rates vary by crop.
Field Corn:

• Apply Lontrel XC alone or in a tank mix with glyphosate. Apply when field corn is at the spike to 8-leaf stage of growth
• 69 mL/acre: Tank mix with glyphosate for enhanced control of Canada thistle, dandelions, perennial sow-thistle and wild buckwheat.
• 101 mL/acre: Canada thistle (top growth), vetch and alsike clover

Cereals (spring wheat, winter wheat, durum wheat, barley):

• 101 mL/acre: Canada thistle (top growth), vetch and alsike clover
• 69-101 mL/acre: Tank mix with 2,4-D Ester or Amine, MCPA Ester or Amine for enhanced control of Canada thistle as well as weeds listed on the tank mix label.

Canola (Ontario only):

• 101 mL/acre: For top growth control of Canada thistle
• Make one application per season; post emergent. Apply at the 2-6 leaf stage of canola, when weeds are actively growing. Apply to Canada thistle at the rosette to pre-bud stage.

Sugar Beets:

• 138-202 mL/acre: For control of Canada thistle and other labelled broadleaf weeds, apply either broadcast or as a band over the row. When applied in the band, the amount of Lontrel XC herbicide should be reduced proportional to the bandwidth. Lontrel XC herbicide should be applied when sugar beets are in the cotyledon to 8-leaf stage. For the most effective control of Canada thistle, apply Lontrel XC herbicide as a broadcast treatment to the entire infested area. 

Rutabaga:

• 138 mL/acre: For control of common ragweed, apply Lontrel XC in approximately 200 to 300 L/ha of water. Apply as a post-emergent spray when ragweed plants are 5 to 10 cm tall. Application to larger ragweed plants will result in reduced weed control. Make only one application per season. 

Treat target weed species in a young, growth life cycle, when the Canada thistle is in the rosette to pre-bud stage but prior to purple bud stage and volunteer alfalfa is 5-50 cm in height.

• Field corn: spike to 8-leaf
• Cereal: 3-leaf to flag leaf
• Canada thistle: rosette to pre-bud

Apply to target weed species when they are young and actively growing. Only weeds present during application will be controlled.

Fields previously treated with Lontrel XC herbicide can be seeded the following year to wheat, oats, barley, rye (not underseeded with legumes, clover or alfalfa), forage grasses, flax, canola, mustard, soybeans*, field peas*, sugar beets or can be summer fallowed.
*Fields previously treated with Lontrel XC up to 101 ml/acre can be seeded after a minimum of 10 months to soybeans and field peas. Very dry soil conditions following application can result in a risk of injury to soybeans or field peas grown in rotation. If severe drought conditions (less than 38 cm rainfall in the 10 months following application) are experienced in the year of application, delay seeding soybeans and field peas an additional 12 months (total of 22 months following application).
Do not seed to crops other than those listed above in the calendar year following treatment.

Tank mix by following these steps:       

1. Fill the spray tank with ½ to ¾ of the required amount of water.
2. Continue agitation throughout the mixing and spraying procedure.
3. Add any required water conditioners.
4. Add any dry formulation tank mix partners.
5. Add the required amount of grassy weed tank-mix partner.
6. Add the required amount of Lontrel XC™.
7. Add any required adjuvant or surfactants.
8. Complete filling the sprayer tank with water.

Note: Do not mix undiluted herbicides in the chem-handler.

Group 4

Lontrel XC herbicide may be safely tank mixed with many other registered herbicides. Refer to the specific crop use recommendations for tank mix guidance.

PRE-HARVEST INTERVAL (PHI)

• The PHI for sugar beets treated with Lontrel XC is 90 days.
• The PHI for rutabaga is 83 days.
• The PHI for durum wheat (Eastern Canada) is 60 days.
• For field corn, do not allow livestock to graze treated areas or harvest treated field corn for silage as feed within 40 days after last treatment.
