How it Works

Pre-seed/Pre-emergence

  • Broadleaf weed control in as few as 3 to 5 days, depending on growing conditions.
  • Unique Kixor® herbicide controls Group 2-resistant and glyphosate-resistant broadleaf weeds.
  • Rainfast and quickly absorbed for fast, complete weed control even under cool conditions.
  • Provides suppression of secondary broadleaf weed flushes when applied at appropriate rates.

Pre-harvest

  • An easy-to-use liquid formulation for fast dry down of broadleaf crops and broadleaf weeds.
  • Improves crop uniformity and speeds up harvest.
  • Fast, complete broadleaf weed dry down for cleaner fields in the next season.

Application Tips

Pre-seed/Pre-emergence

  • Heat LQ is very rainfast and will be limited by the type of glyphosate used. Follow the glyphosate manufacturer’s recommendation for rainfast guidelines.
  • Always add Merge adjuvant.
  • Use a minimum water volume of 5 gal/ac to maximize coverage.
  • If weeds are large or densities are high, use a minimum water volume of 10 gal/ac.

Pre-harvest Harvest aid

  • Heat LQ is very rainfast and will be limited by the type of glyphosate used. Follow the glyphosate manufacturer’s recommendation for rainfast guidelines.
  • Use a minimum water volume of 20 gal/ac to maximize coverage in stand-alone ground applications.
  • Use a minimum water volume of 10 gal/ac to maximize coverage in tank-mixed ground applications.
  • Use a minimum water volume of 5 gal/ac for aerial applications.

The tank mix with glyphosate may affect the seed germination. DO NOT tank mix with glyphosate when harvested grain is to be used for seed. DO NOT tank mix glyphosate with Heat LQ on sunflowers.

When to Apply

Crops and staging

Pre-seed/Pre-emergence

Barley,
Canary seed,
Chickpeas (kabuli),
Corn (field, sweet),
Field peas,
Lentils,
Tritacle,
Soybeans,
Wheat (spring, winter, durum)
Apply pre-seed and pre-emergence (before ground crack) prior to seeding the following crops:
Chemfallow Apply to actively growing weeds.

Pre-harvest1

Canola Apply when 75% of seeds have changed colour.
Dry common beans2, soybeans Apply when stems are green to brown, pods are mature (yellow, brown) and 80 to 90% of leaves have dropped.
Field peas Apply when majority of pods are brown (70 to 80%).
Red Lentils3 Apply when bottom 15% of the pods are mature and brown with rippened seeds. The bottom pods should rattle when shaken.
Sunflowers4 Apply when the backs of the heads and bracts are turning yellow, and seed moisture is 20 to 30%.

Pre-harvest Weed Management

Barley5 (spring, winter),
triticale,
wheat (spring, durum, winter)
Hard dough stage with less than 30% moisture.
A thumnail impression remains on seed.

Maximum Residue Limits

Please note: Heat LQ can be used for pre-harvest applications on barley, canola, chickpeas, dry common beans, field peas, red lentils, soybeans, sunflowers, triticale, and wheat for the 2017/2018 application season.

At the time of printing (2017), BASF remains in the final stages of establishing import tolerances (maximum residue limits (MRLs)) for flax and mustard for markets around the world. While establishing MRLs for key export markets is progressing, the European Food Safety Authority has not yet completed their review. Because these crops are heavily exported, and some exports are made to the EU, BASF does not recommend the use of Heat LQ as a harvest aid on flax and mustard for the 2017/2018 application season.

1 Heat LQ herbicide must be applied after physiological maturity (less than 30% seed moisture).
2 When tank mixed with glyphosate, consult glyphosate label for full information.
3 BASF supports the use of Heat LQ for pre-harvest for red lentils, however we are still in the process of aligning the Maximum Residue Limit (MRL) in the European Union with other trade jurisdictions. NOTE: Heat LQ is supported for pre-harvest use on red lentil varieties only. DO NOT apply Heat LQ pre-harvest to green lentils. Please check with your grain buyer prior to the pre-harvest application of Heat LQ in red lentils.
4 Glyphosate is not registered for pre-harvest use in sunflowers. When applying to sunflowers, use Heat LQ as a stand-alone product only.
5 At this time, BASF supports the use of Heat LQ herbicide for pre-harvest on feed barley only. Please check with your maltster prior to the pre-harvest application of Heat LQ on malt barley.

How Much to Apply

Pre-seed/Pre-emergence

One case of Heat LQ herbicide will treat 30 to 80 acres, depending on rate used.

Barley, canary seed, chickpeas (kabuli), corn (field, sweet1), field peas, tameoats, wheat (spring, winter, durum) 21.5 to 59 ml/ac
(53 to 146 ml/ha)
Lentils2, soybeans2,3 21.5 ml/ac
(53 ml/ha)
Chemfallow 21.5 to 59 ml/acbr
(53 to 146 ml/ha)

All applications

Glyphosate4(360 g ae/L equivalent) 0.5 to 1 L/ac (1.25 to 2.5 L/ha)
Merge adjuvant5 200 ml/ac (500 ml/ha)

Water volume

Ground application 20 to 40 L/ac (5 to 10 gal/ac)

1 Some sweet corn hybrids may be sensitive to saflufenacil and injury may occur.
2 Do not use rates higher than 21 ml/ac (53 ml/ha) or injury could result. See label for details.
3 Some soybean cultivars may be more sensitive to saflufenacil and injury may occur.
4 Glyphosate (required for optimum activity) is not included in the case.
5 Merge adjuvant is required and is included with Heat LQ herbicide.

Pre-harvest

One case of Heat LQ herbicide will treat 30 to 40 acres (depending on rate) tank mixed with glyphosate or 30 acres standalone. One tote treats 730 to 1,000 acres (depending on rate) tank mixed with glyphosate or 730 acres standalone.

Heat LQ stand-alone rate 59 ml/ac (146 ml/ha)
Merge adjuvant6 400 ml/ac (1 L/ha)
Heat LQ tank mixed with glyphosate rate 43 to 59 ml/ac (106 to 146 ml/ha)
Glyphosate7(360 g ae/L) 1.0 L/ac (2.5 L/ha)
Merge adjuvant6 200 ml/ac (500 ml/ha)

Heat LQ should always be tank mixed with glyphosate in canola and cereals.

Water volume

Ground application stand-alone rate 80 L/ac (20 gal/ac) minimum
Ground application tank mixed with glyphosate rate 40 L/ac (10 gal/ac) minimum
Aerial application8 20 L/ac (5 gal/ac)

6 Merge adjuvant is required and is included with Heat LQ herbicide.
7 Glyphosate is not included in the case.
8 Heat LQ is registered for aerial applications. Some glyphosate formulations are also registered for aerial applications, therefore Heat LQ plus glyphosate can be applied through aerial applications, therefore Heat LQ plus glyphosate can be applied through aerial applications when both products have aerial registrations.

Mixing order

  1. Fill clean spray tank 1/2 full of clean water and start agitation.
  2. Add the correct about of Heat LQ herbicide and continue to agitate until mixed.
  3. If tank mix is being applied, add the correct amount of glyphosate while continuing agitation.
  4. Add the correct amount of Merge adjuvant to the tank last.
  5. Continue agitation while adding the remaining amount of water.
  6. Continue agitation or run the by-pass system.
