Heat LQ

Pre-harvest

• Rainfastness – Heat LQ is extremely rainfast and is only limited by glyphosate.
  
• Follow the glyphosate manufacturer’s recommendation for rainfast guidelines.

Pre-harvest

Maximum Residue Limits
Please note: At the time of printing (2023), BASF has not fully established import tolerances (maximum residue limits (MRLs)) for mustard for all markets around the world. Because this crop is heavily exported, and some exports are made to markets where these MRLs have not been established, BASF does not recommend the use of Heat LQ as a harvest aid on mustard for the 2023 season.

_{¹ Heat LQ herbicide must be applied after physiological maturity (less than 30% seed moisture).
² Consult with grain buyer prior to application as the Keep It Clean 2023 Product Advisory indicates caution for glyphosate applications on all pulse crops except red lentils.
³ When tank mixed with glyphosate, consult glyphosate label or your BASF Sales Representative for information regarding use on specific varieties of dry common beans.
⁴ Glyphosate is not supported for pre-harvest use on flax. Use Heat LQ as a standalone product only.
⁵ 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.
⁶ Glyphosate is not registered for pre-harvest use in sunflowers. Use Heat LQ as a standalone product only.
⁷ BASF supports the use of Heat LQ herbicide for pre-harvest on feed barley only.}

Pre-harvest

One case of Heat LQ herbicide tank mixed with glyphosate will treat 40 acres. One tote treats 1,000 acres.

(Heat LQ should always be tank mixed with glyphosate.)¹⁰
(Use all Merge included in the case or tote of Heat LQ.)

Water volume

_{⁸ Glyphosate is not included in the case.
⁹ Merge adjuvant is required and is included with Heat LQ herbicide. Use all Merge included in the case.
¹⁰ Glyphosate is not recommended for use on flax.
¹¹ Heat LQ is registered for aerial applications.}

Mixing order

1. Fill clean spray tank 1/2 full of clean water and start agitation.
2. Add the correct amout of Heat LQ herbicide and continue to agitate until mixed.
3. 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.

Pre-harvest

In the spring following fall application.

Barley (spring, malt, winter)
Canary seed
Canola (all types incl. Clearfield^® canola)
Chickpeas
Corn (field and sweet)
Field peas
Flax
Lentils
Oats
Soybeans
Wheat (spring incl. Clearfield wheat, winter, durum)

Pre-harvest interval

2 days after application for chickpeas and dry common beans.

3 days after application for barley, canola, field peas, flax, red lentils, soybeans, triticale and wheat.

7 days after application for sunflowers.

_{Note: Consult glyphosate label for more information including pre-harvest interval and staging.}

Pre-seed/Pre-emergence/Chemfallow

_{¹ Depending on growing conditions.
² Includes Group 2-resistant and glyphosate-resistant biotypes.
³ For suppression of secondary flushes in addition to rapid burndown, use higher application rate of 59 ml/ac (146 ml/ha).
⁴ Top growth burndown control only of perennial plants, control of spring germinating plants.
⁵ All herbicide-tolerant canola systems including glyphosate-tolerant canola.}

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.

Smoulder^® herbicide is another pre-seed option for barley and wheat (durum, spring and winter).
Voraxor^® herbicide is an additional pre-seed option for peas, lentils, corn, soybeans, wheat and barley.

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.

Crops and staging

Pre-seed/Pre-emergence

Pre-seed/Pre-emergence

One case of Heat LQ herbicide will treat 30 to 80 acres, depending on rate used. One tote treats 2,000 acres for lentils and soybeans and 730 to 2,000 acres for all other crops.

All applications

Water volume

_{¹ Some sweet corn hybrids may be sensitive to saflufenacil and injury may occur.
² Do not use rates higher than 21.5 ml/ac (53 ml/ha) or injury could result. See label for details.
³ Do not use rates higher than 29.5 ml/ac (73 ml/ha) or crop injury may result. See label for details. Some soybeans 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.}

Mixing order

1. Fill clean spray tank 1/2 full of clean water and start agitation.
2. Add the correct amout of Heat LQ herbicide and continue to agitate until mixed.
3. 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.

Pre-seed/Pre-emergence

All crops, 1 year after a spring, pre-seed or pre-emergent application.
