Heat LQ
Maximize efficiency with enhanced crop and weed dry down.
When deciding to straight cut your canola, Heat® LQ herbicide can help you cross the finish line quicker. It delivers consistent crop and weed dry down, for easier stock cutting and increased harvest speeds. Heat LQ is also the perfect match for InVigor® canola hybrids with patented Pod Shatter Reduction technology. For a smoother, more profitable finish.

Pre-harvest Harvest aid
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
Crop | Staging |
---|---|
Barley2, triticale, wheat (spring, durum, winter) |
Hard dough stage with less than 30% moisture. A thumbnail impression remains on seed. |
Canola |
Apply when the crop has reached 80% seed colour change. |
Chickpeas | 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 beans3, soybeans |
Apply when stems are green to brown, pods are mature (yellow, brown) and 80 - 90% of leaves have dropped. |
Field peas |
Apply when 75% of pods have dried down. Peas should be firm in remaining pods. |
Red Lentils4 |
Apply when 75% of seeds are mature, having <30% kernel moisture. |
Sunflowers5 |
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 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.

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.
One of the most important factors of a successful pre-harvest dry down is water volume. Apply Heat LQ herbicide in a water volume of 10 - 20 gal/ac and at a pressure of 240 kPa. For applications to dense weed infestations and thick canopies, use a higher water volume at a pressure of 275 kPa. The rate of dry down also increases with water, so consider using different volumes to stagger your straight cutting operations.
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.

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.

Pre-seed/Pre-emergence
All crops, 1 year after a spring, pre-seed or pre-emergent application.
For strictly pre-seed burndown control, Heat LQ plus glyphosate is effective at the 80-acre rate. For additional residual on volunteer canola, wild buckwheat, cleavers and stinkweed, Heat LQ plus glyphosate provides excellent residual suppression at the 30-acre rate. Heat Complete plus glyphosate provides residual suppression of all those weeds with the addition of kochia, pigweed, lamb's quarters, wild oats, and green and yellow foxtail.
Group 14 chemistries, such as Heat LQ herbicide, seem to be one of the best options. With kochia, it's important to make the following two assumptions: glyphosate resistance is more than likely and it's safe to assume that all kochia in Western Canada is also Group 2-resistant. That leaves Group 3, 4, 5 and 14 for use as pre-seed burndown options for cereals. Regarding best practices, slow down the sprayer (no more than 14 mph), lower the boom height (no higher than 26 inches), increase water volumes (specifically for Group 14 products that have contact activity), rotate chemistries and consider a forage crop in the fall that will take up available moisture and compete with kochia.
