Heat LQ

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 10 gal/ac to maximize coverage when tank-mixed with glyphosate in ground applications.
• Use a minimum water volume of 5 gal/ac for aerial applications.

For best results, it is recommended that Heat LQ be tank mixed with glyphosate on most crops to improve the speed of crop and weed dry down. Glyphosate is not registered for pre-harvest application on sunflowers.

Pre-harvest¹

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 BASF supports the use of Heat LQ herbicide for pre-harvest on feed barley only. 
³ When tank mixed with glyphosate, consult the glyphosate label or your BASF Sales Representative for information regarding use on specific varieties of dry common beans. 
⁴ 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 your grain buyer prior to the pre-harvest application of Heat LQ in red lentils. 
⁵ Glyphosate is not registered for pre-harvest use in sunflowers. For sunflowers, use Heat LQ as a standalone product only.} 

Pre-harvest

One case of Heat LQ herbicide tank mixed with glyphosate will treat 40 acres when used on canola, peas, lentils and other registered crops. When using Heat LQ and glyphosate on cereals, one case will treat 40 to 60 acres depending on rate.

Water volume

_{⁶ Do not apply glyphosate on sunflowers. 
⁷ Glyphosate is not included in the case.
⁸ Merge adjuvant is required and is included with Heat LQ herbicide.
⁹ 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, winter)
Canary seed
Canola (all types incl. Clearfield^® canola)
Chickpeas
Corn (field and sweet)
Dry common beans
Field peas
Flax
Lentils
Mustard
Oats
Soybeans
Wheat (spring incl. Clearfield wheat, winter, durum)

Pre-harvest interval¹

2 days after application for chickpeas and dry common beans.

3 days after application for barley (including feed varieties), canola, field peas, red lentils, soybeans, triticale and wheat.

7 days after application for sunflowers.

_{¹ When tank mixed with glyphosate, the pre-harvest interval for the most restrictive product must be followed. In most cases, this is 7 - 14 days for glyphosate. Check the glyphosate label for detailed information.}

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.
