Courtney Stephenson
Courtney Stephenson has been with Bayer for 9 years, with roles in Sales, Communications and most recently with the Seeds team. In addition, she has worked within the independent retail network, as well as government research. While Courtney grew up in Southern Alberta, she also has roots in Southwest Manitoba where her family farms. Her favourite crop is barley, but has found her passion with canola.

When Courtney is not working on InVigor canola, she spends her time either jumping or driving horses, and cursing the quackgrass in her flower beds.

Allison McLellan
Allison McLellan worked in canola breeding before becoming a Bayer Field Marketing Specialist in Southern Alberta two years ago. Her latest passion is cereal fungicides and how they perform in the challenging conditions of Southern Alberta fields. Originally from a family farm in Holdfast, Saskatchewan, Allison’s own knowledge of combines is quite remarkable!

When she is not working with her growers on Demonstration Strip Trials, Allison is happy to spend her time hunting gophers and mowing grass.

Niel Bertsch
Neil Bertsch is proud to say that he has been farming with his family for over 30 years in the Drumheller area. The Bertsch’s are a great example of a family farm, with all members playing a role in the success of the farm; so much so that they won the Farm Family Award for Kneehill County in 2013. Their rotation is wheat, canola and peas, and have been participating in the Bayer Demonstration Strip Trial program since 2011.

When Neil is not farming he is either winning tractor pulls or driving his Indian Road Master motorcycle across the continent with his wife, Lonna.

Seeding Questions

Seed Treatment Questions

Herbicide Questions


Q: When should AMS be added, in Manitoba, specifically?
In cool conditions or when heavy weed populations are present. Varro and Velocity are the best group 2’s on yellow foxtail, but AMS will strengthen them.



Q: Sprayed Varro and Buctril M on spring wheat 10 days ago. Can I spray Refine
SG now?
A: This would be no different than spraying Varro+Refine in a tank mix. It indicates that this use is acceptable as Buctril M has no residual activity and the label statement was intended to reduce the potential for group 2 residual stacking concerns.

Q: Spray Buctril M on Proso Millet?
A: Should be fine, expect to see some leaf burn under hot conditions.



Q: Can I TM Centurion + Glyphosate to spray on RR canola to target Grp 2 resistant weeds?
A: You can (no antagonism), but there is really no added value. A full rate of Glypohsate should be enough to control the wild oats. If there are any escapees, and greater control is needed later on, a second application with Centurion (at full rate) could be made.

Q: What is the TM order for Centurion, Seven XLR and Liberty?
A: 1. Amigo 2. Sevin XLR 3. Liberty 4. Centurion

Q: What is the TM order for Seven XLR and Centurion?
A: 1. Seven XLR Plus 2. Centurion 3. Amigo



Q: Sprayed infinity and axial on barley 4 days ago, how long until I see results?
A: 6-14 days you will see broadleaf activity if applied according to label parameters.

Q: Do you have a product that will control Black Medic?
A: Infinity - we only have a couple of trials, but control should be very good.

Q: Why does it say "in Manitoba only" for re-cropping soybeans after using Infinity?
A: Because the work has not been done in SK or AB yet. Consult with your local BCS rep.

Q: What is the tank mixing order for Infinity when adding Liquid Achieve?
A: 1-AMS, 2-Achieve, 3-Infinity, 4-Turbocharge

Q: Can one spray Infinity tank mixed with Sierra?
A: No not registered or supported.

Q: What is TM order for Infinity FX and Axial?
A: TM order is 1. FX 2. Infinity 3.

Q:  What is the difference between Infinity and Infinty FX?
  Infinity FX is Infinity co-packed with fluroxypyr (FX Herbicide), which provides you with three herbicide Groups (27, 6 and 4) utilizing both systemic and contact activity. The co-pack treats 40 acres and BOTH jugs are required to achieve recommended rates of Infinity and fluroxypyr.

Some additional features include:

  • Outstanding control of cleavers and kochia in addition to many other tough-to-control broadleaf weeds
  • Exceptional resistance management – with Infinity FX you get the activity of three different herbicide Groups on the same weed species
  • Contains unique Group 27 chemistry, still the newest cereal herbicide Group in Canada
  • Powered by pyrasulfotole, super-charged with bromoxynil and boosted with fluroxypyr, Infinity FX has speed of activity that is visible within days
  • Tank-mix friendly, Infinity FX is the preferred tank-mix partner with all major graminicides including: Varro®, Puma® Advance, Axial® BIA, Horizon® NG and Liquid Achieve™
  • Option to add AMS for increased control of specific problem weeds
  • Wide window of application and excellent crop safety
  • Convenient 40 acre co-pack



Q: Can I spray Liberty on flowering canola?
A: Liberty is registered for canola from cotyledon to early bolting.
A: Don’t spray when flowering as it can interfere with pollination. If Liberty is applied after flowering, it can run the risk of pollen inactivation, and can even burn the flowers.
Spraying at the bud stage does not harm the flowers. The decision to spray needs to be made based on weed control versus yield dockage. Growers discretion to make the call.

Liberty is registered from cotyledon to early bolting. It is up to the grower’s discretion to spray past the labelled staging (early bolting). Liberty does not cause sterilization. It is possible that the surfactant in Liberty can “blast” some flowers under very hot humid conditions. It is more likely that the surfactant has an impact on pollen, however so can excessive rainfall and high temperatures. Bottom line: Growers can spray up to flowering stage and after that we do not encourage late applications.

Q: Can I use Liberty as a desiccant on Lentils?
A: No, we no longer support dessication use according to the LTA the grower signs. Bayer will not support the use of Liberty on any crop that is not listed on the Liberty label. The only crops on the Liberty label are LibertyLink® canola, LibertyLink soybean and LibertyLink corn.

There is limited Maximum Residue Limits (MRL’s) established in export markets for this use pattern. Therefore, growers using Liberty on an unregistered crop risk not being able to market their crop.
All growers purchasing Liberty have signed the Liberty & Trait Agreement (LTA). Under the LTA, growers have agreed to use Liberty in accordance with the label and only on the crops listed on the label.

Q: Will Liberty control narrow leaved hawks beard?
A: Off label. Yes, just up the water volume for good coverage and spray at 1.62 L/ac.

Q: Can I tank mix Liberty + Lontrel?
A: No. Liberty works too fast for the Lontrel to be effective on particular weeds. Liberty provides a quick burn down on thistle, and the Lontrel won't be completely taken up by the plant. Split the application, going in with Lontrel first, wait 7 days, then follow with the Liberty application.

Q: What is the recommended water volume to be used when applying Liberty?
A: 10 US gal/acre for ground application.

Q: What is the rainfast for Liberty?
A: 4 hours

What stages is Liberty safe on Canola?
At a rate of 1.35 L/ac-1.62 L/ac, Liberty is registered from cotyledon to early bolting.

Q: What is the TM order for Centurion, Seven XLR and Liberty?
A: 1. Amigo 2. Sevin XLR 3. Liberty 4. Centurion 



Q: Can we spray Pardner on an alfalfa and sweet clover crop?
A: Alfalfa- Registered on seedling (2-6 trifoliate) and established (up to 25 cm in
height) alfalfa for seed production only. Established alfalfa past 25cm Will burn the
tops off. Need to be concerned with bud damge and could affect seed production.
Need to question size of weeds and there could be coverage issues due to size of

Sweet clover-Control on Sweet Clover?
Off Label: Not registered. Sweet clover as a weed: Will burn leaves but will not
control plant, should expect regrowth.
Sweet clover as a crop: too much crop injury, not recommended.

Q: Can one tank mix and spray Pardner and Centurion with alfalfa?
Pardner can be tank mixed with Centurion on alfalfa. As long as the alfalfa is in the 2nd or
3rd trifoliate.

Can Pardner be sprayed post-seeding in canola.
No, application needs to take place prior to canola seeding.



Q: Can you still use Puma Advance that has been frozen?
A: Off Label: The problem won’t be product performance but potential issues with plugging a
growers screens or filters.



Q: Is Sencor registered on sunflowers?
A: No, Sencor is not registered on sunflowers.

Q: Does Sencor need a surfactant?
A: No surfactant is needed.

Q: What is the rainfast for Sencor?
Rainfast is 6 hours, but avoid applying if the short term forecast calls for 2+ inches of rain, or if it is calling for cool, overcast weather for the next few days.



Q: Can I mix Thumper with 2,4-D Ester?
A: Yes, you can. 2 active ounces/acre. 1. Thumper 2. 2,4-D Ester.


Q: Tank mix order of Puma Advance and Prestige?
A: 1. Prestige XC > 2. Puma Advance

Q: What is the timing for application of Tundra on barley for the crop and for the volunteer
A: 1-6 leaf, up to 3 tillers for the barley and 1-6 LS for the volunteer canola.



Q: What is the tank mix order for Velocity M3 and AMS?
A: 1. AMS > 2. Velocity M3

Q: Does Velocity M3 target tansy mustard?
A: No, there is no registered control for tansy mustard.

Q: Do Varro or Velocity have control on Downy Brome?
50-60% suppression can be expected on spring germinated Downey Brome.  Growers are recommended to use a burndown followed by early weed removal when planning a program for Downey Brome. Simplicity only has suppression of Downey Brome as well.


Fungicide Questions


Q: Is it necessary to rinse out the tank between fungicide applications? (Fungicide app on wheat to fung app on canaola, vice versa).

A: No, a full rinse out is not necessary. As much product as possible should be sprayed out but a little bit of spray solution left in tank before starting to fill for next fungicide application is okay.


Q: Delaro + Centurion on lentils that are at the 20% flowering stage?
A: Unlabelled tank mix: Mixing Order is Delaro - Centurion - Amigo. Lentils are tolerant to Centurion at flowering stage but observe PHI which is 60 days.

Q: Delaro + Decis ok to tank mix?
A: Unlabelled tank mix (Lentils only): Mixing Order is Delaro - Decis.

Q: Does Delaro require an adjuvant?
A: In Soybeans only. The use of a non-ionic surfactant at 0.125% v/v (Ag Surf or Agral 90) may be used with Delaro fungicide.

Q: What temperatures for spraying Delaro?
A: Nothing out of the ordinary. Use common sense and don't spray in the middle of the day with temps nearing 30C or above. If spraying in hotter than normal weather it is important to keep water volumes at 10 gal/acre.



Q: Do I have to wait for my crop to completely dry off before applying fungicides such as Proline and Prosaro?
A: A completely dry canopy is not necessary, however if the canopy is completely soaked allow for some drying to occur.

  • If it is enough that it will drip off when the chemical is sprayed on, wait a couple hours for it to dry off (easier with the horizontal leaves of canola).
  • If it is just a very light dew (not enough for drip off when the chemical is added), it should be okay.
  • It is important to concentrate on the best coverage you can get with the combination of water volume, pressure and speed.

Q: TM Folicur with Refine SG?
A: No, use Tilt.

Q: Spraying Folicur on CWRS, what rate?
A: 40ac/jug if spraying at full rate, 53ac/jug if spraying at 3/4 rate. 3/4 rate only registered at flag leaf timing in wheat. Full rate is registered at heading and at flag leaf timing.

Q: Surfactant needed for Folicur EW?
A: No, it is already in the formulation.

Q: Applying Prosaro on wheat that borders a canola field. Any issues on drift into the canola?
A: There will not be any issues, but he should try to minimize the drift because tebuconazole is not registered in canola in Canada.

Q: What is the best timing for an application of Prosaro?
A: Head extended up from flag leaf, first flowers visible.

Apply between 75% of wheat heads on the main stem are emerged to 50% of heads on the main stem are in flower. Optimum timing is when flowering starts and anthers are only visible in the middle of the head.

Apply at 70% main stem head emergence to 3 days after full head emergence. Optimal timing is just after head emergence. Target timing: Full heading.

Q: Spraying on durum for fusarium head blight, how long is window of protection once I spray Prosaro?
A: The Longest in the industry. Length of protection varies depending on variety resistance to FHB, environment (whether conducesive for disease development), relative pathogen pressure, and application timing and method are also important. In addition to the quality benefits from reduced DON levels in the seed, and plumper seeds, there’s the yield advantage which is unprecedented. Some of this comes from controlling leaf and head diseases in addition to the fusarium.



Tank mix order for Proline with Centurion?
A: 1. Proline > 2. Centurion > 3. Amigo Ref> Quick Sheets

Q: Does Proline require an adjuvant?
A: Surfactant Required: Non-Ionic Surfactant (Agral 90 or AgSurf) @ 0.125% v/v

Adjuvant Exception: No surfactant required when applying to canola, although the lowest labelled rate of a NIS (AgSurf or Agral 90) may be used with Proline but is not required. (Adjuvant is a sticking agent, canola's horizontal leaves penetrate/stick better, thus is not required). * Exception applies to Proline on canola, rapeseed, oriental mustard, chickpeas, lentils, soybean, corn, flax, sunflower & safflower *

Q: What is the best timing for an application of Proline?
A: Canola - apply between 20-50% bloom stage (15-20 flowers on main stem), prior to petal fall.

Harvest Questions

Insecticides Questions


Q: Can you spray Decis with OcTTain?
A: No, not registered or supported.

Q: Can I spray Decis when my plants are still wet from a heavy dew?
A: We recommend morning or evening, so likely fine.

Q: I sprayed Decis, what is re-entry time?
A: 24 hours

Q: Liberty and Decis have been sitting in a sprayer tank for 4 days, what do I do?
A: You can let it sit for 2-3 days with agitation every 4 hours. After 4-5 days start topping up at 20%.

Other Questions


Q: How long can my tank mix sit in the tank prior to degrading? (sprayer broke down)
A: All of our products should be good for a week in the tank depending on water quality, tank mix partner and temperature, but agitate daily. However, Centurion (Clethodim) can photodegrade over time. We recommend moving out of the sunlight or covering plastic/poly tanks with a tarp. For the first 24 hours it is fine, after that, activity can be reduced by 50% ever 24 hours. Consider bumping up the rate at that point. Agitate every 3-4 hours if possible. The Centurion won't hurt the crop, but we cannot guarantee the efficacy.
