Application Tips


Pre-harvest

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

When to Apply

Pre-harvest

 

Crops Staging1

Harvest Aid

  

Canola

 Apply when the crop has reached 80% seed- colour change.

Chickpeas2

 Apply when majority of plants are mature with only the upper part remaining green. Seed moisture is 30% or less. Majority of Desi type seeds are yellow/brown, and Kabuli type seeds are tan/white.

Dry common beans2,3, soybeans2

Apply when stems are green to brown, pods are mature (yellow, brown) and 80 - 90% of leaves have dropped.

Field peas2

 Apply when about 75% of pods have dried down (changed colour).

Flax4

 Apply when 75 to 80% of bolls are brown and when seed moisture is less than 30%.

Red Lentils5

Apply when bottom 15% of pods are mature and brown with ripened seeds. The bottom pods should rattle when shaken.

Sunflowers6

 Apply when the backs of the heads and bracts are turning yellow, and seed moisture is 20 - 30%.

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.

FAQs from the Field – Staging for Heat LQ pre-harvest aid

Know when to apply Heat LQ herbicide as a pre-harvest aid at the right stages for your canola and cereals.

FAQ

What environmental conditions help Heat LQ work the best as a pre-harvest aid?

Similar to all pre-harvest aids, Heat LQ plus glyphosate will work best under favourable environmental conditions like warm temperatures, high sunlight and low humidity.

 

Adverse weather conditions such as rainfall, cool temperatures, smoke or high humidity will slow your canola crop dry down.

 

To optimize these conditions, slow your sprayer speeds, use higher water volumes (40 L/ac when tank mixed with glyphosate), use nozzles that point backwards and adjust for finer droplets to penetrate the canopy for a more thorough and even dry down.

How much glyphosate should I add to Heat LQ pre-harvest?

It is recommended to use 1 REL of glyphosate.

Which type of barley can I spray Heat LQ pre-harvest on?

Heat LQ is only registered for use on feed barley.

It is getting later in the season (i.e., after September 30th) and I want to use Heat LQ to dry down my canola crop. How do I maximize the effectiveness of this application?

You can improve the effectiveness of your Heat LQ + glyphosate application by increasing the water volumes and go up to 20 gallons per acre.

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.

 

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.
