Q: Can I spray Buctil M (on flax) in extreme heat? It has been in the mid 30's this week and is supposed to continue for a week or so?
A:No, we do not recommend spraying when temperatures exceed 30°C. If the evening temperatures start dipping down, you could spray then; remember to keep water volume at 10 (good) to 15 (better) US gallons per acre. There is a high risk of evaporation during with high temperatures and increasing the water volume will help mitigate and also improve control as Buctril M does rely on some contact activity. Humidity is not an issue. Spraying at the right staging is the most critical.
Q: My peas are in the early bud stage. Can I spray Centurion?
A: You need to observe the 75 day pre-harvest interval and make sure you are not spraying during flowering as it can knock off petals and cause pollination issues. Otherwise, Centurion is safe on the peas at all growth stages.
Q: Can you spray Centurion on flowering lentils?
A: No, do not spray Centurion on flowering lentils. Centurion is okay on lentils but only up until flowering. Pre-harvest interval for lentils is 60 days.
Q: Can you spray Centurion on bolting canola?
A: Yes, you can spray Centurion on bolting canola. Centurion is okay only up until flowering. PHI for canola is 60 days.
Q: I want to do a second pass on my InVigor canola as I have a 2nd flush of wild oats. Can I use Centurion again, even if I used it on my 1st pass?
A: Yes, Centurion can be applied multiple times per year, including both Liberty passes.
Q: What is the recommended rate of Amigo with 40-60 acres/case of Centurion?
A: We recommend that you use all of the Amigo with 40-60 acres/case of Centurion.
Q: Can you tank mix Centurion and Basagran?
A: No, Basagran will antagonize the clethodim. Recommend to spray Centurion, then wait 4 days to spray a non-tank mixable product.
Q: Can I apply more than one application of Centurion in a season on my flax?
A: Yes, at any rate. Centurion cannot be applied to blooming crops and the PHI must be followed to avoid excessive crop residues. It is also important to keep in mind the growers’ herbicide rotations and resistance.
Q: Can I spray Centurion on my peas at the first node stage?
A: Yes, peas are tolerant to centurion at all stages of growth.
Q: Can I tank mix Infinity FX + Assert?
A: No, this is not a registered tank mix.
Q: What is the rain-fast of Infinity FX?
A: Rain-fast of Infinity FX is 1 hour.
Q: What is the tank mix order for Axial, AMS and Infinity FX?
A: 1. AMS
Q: What is the mixing order for Varro & Infinity FX? Is AMS a requirement in the tank mix (Manitoba grower)
A: Tank Mix Order:
3. FX Herbicide
Note that AMS is not a requirement.
Q: Can you spray Infinity on Oats?
A: No – heavy rain can cause the product to wash into the root zone after an application, which could be taken up by the roots of the crop and can cause whitening symptoms.
Q: How long does it take for Liberty to work?
A: Results should be visible in 2-5 days. Development of visual symptoms depends on the weed species and environmental conditions. About 1 to 2 days after application, faint pale green or yellowish discoloration appears on the leaves. These initial symptoms subsequently turn into leaf chlorosis and finally, necrosis. In some weed species, chlorotic and desiccated leaf zones appear simultaneously, whereas in other species (often observed in grass species) extensive chlorosis develops initially and is followed later by desiccation which expands from the leaf tips. Complete death of the weeds usually occurs between 1 and 3 weeks after treatment.
Q: Can I tank mix Liberty and Matador?
A: We do not support this tank-mix. Other supported tank mixes include Decis and Sevin.
Q: Can I tank mix Liberty with Headline?
A: No, it is not a registered or supported tank mix.
Q: Can I mix the product, Pounce, with Liberty?
A: No, it is not a registered tank mix.
Q: What is the rainfastness of Liberty?
A: 4 hours.
Q: When using Liberty 432 L shuttles, should I go by the lines or numbers on the side of the shuttle?
A: We recommend using a calibrated pump to measure your Liberty. We load by weight so the markings and numbers on the containers are only a rough guideline.
Q: How late can I spray Liberty?
A: Liberty is registered from the cotyledon to early bolting stage. It is up to the grower's discretion to spray past the labelled staging. Liberty does not cause sterilization. It is possible that the surfactant in Liberty can "blast" some flowers under very hot and humid conditions. It is more likely that the surfactant will have an impact on pollen, however, so can excessive rainfall and high temperatures. Bottom line: Growers can spray up to the flowering stage and after that we do not encourage late applications.
Q: Can I use the product, Flush, to rinse out my tank after a Liberty application?
A: Yes, it's an ammonium based cleaner.
Q: When spraying Liberty followed by a separate application of another herbicide, how many days should I wait in-between?
A: The plants need to be actively growing again. Wait at least 4 days after before applying a different chemistry that is not tank mixable. Look for new growth.
Q: At what growth stage of InVigor canola is it safe to spray Liberty?
A: From cotyledon to early bolting.
Q: Can I tank mix Lontrel with my Liberty to control thistles?
A: We do not recommend this. Liberty works too fast for the Lontrel to be effective on particular weeds; hence we recommend applying earlier to ensure it is effective. Liberty provides a quick burn down on thistle, and the Lontrel will not be completely taken up by the plant. Split application of Lontrel first, wait 7 days, followed by Liberty.
LIBERTY + CENTURION
Q: Canola is in the 2 leaf stage, will I hurt it spraying at the 1.62L rate of Liberty, tank mixed with a 60 ac/case rate of Centurion.
A: No, you will not. This is a registered rate. Liberty is registered on InVigor from the cotyledon stage, up to early bolting.
Q: Is it ok to add Matador to Liberty + Centurion and if so what is the tank mix order?
A: No, we do not support this tank mix. If you use Decis, thank tank mix order is: Amigo - Liberty - Centurion - Decis.
Q: If I have half of a tank full of Liberty and Centurion, can I re-fill or do I need to empty my tank first?
A: Yes, you can re-fill a half tank of Liberty and Centurion.
Q: How much Centurion should I add to my Liberty mix?
A: It depends on many factors. 60 ac/case is most popular but we are registered from 20 ac/case to 120 ac/case.
Q: What rate of Centurion should I mix in with Liberty?
A: 60 ac/case is recommended; however we are registered from 40 ac/case to 120 ac/case. The most commonly used rate is between 40-60 ac/case, depending on weed stage and density.
Q: What is the tank mix order for Liberty, Centurion and Decis?
A: 1. Amigo
Q: Which surfactant do I use in Luxxur for enhanced grass control?
A: Unless otherwise noted for all Luxxur tank mixes, add AMS (spring wheat) or NIS (durum wheat) for enhanced grass control
Q: What is the rain-fast of Luxxur?
A: Rain-fast of Luxxur is 4-6 hours.
Q: Can I tank mix Luxxur and Enforcer M?
A: No, this is not a registered tank mix.
Q: What is the tank mix order for Luxxur & Paradigm?
A: 1. Paradigm
2. Luxxur A
3. AMS (0.5 L/acre in spring wheat
4. Luxxur B
5. NIS (0.25% v/v in durum wheat).
Q: Can you tank mix Luxxur with 2,4-D?
A: Yes, Luxxur is tank mixable with 2,4-D Ester.
Q: What is the minimum temperature for spraying Puma Advance + Infinity on barley?
A: Ideal conditions are between 5 and 28°C. If there is a frost, wait at least 48 hours before spraying to ensure plants have recovered from the stress of frost. If nighttime lows reach +3°C or lower, then spraying herbicides are not recommended due to plant metabolism slowing down below this temperature. Ideally, wait until the nighttime low is no lower than +5°C for a minimum of 3 days so the plants are actively growing. This will ensure that the herbicide can be effective as possible and the grower gets the best return on investment.
Q: What is the staging for Sencor on chickpeas?
A: 1-3 above ground node stage (max height of 6 cm) at 111 g/ac.
Q: What are the rates for a split application of Sencor on Lentils?
A: 77 g followed by 57 g. Allow 7 to 10 days between applications.
Q: Grower spraying split application of Sencor on his lentils but has Japanese Brome and wants to use Assure. Can he spray before and if so, how long does he wait until first Sencor application or can he spray in between Sencor applications?
A: If before, the grower can wait 2-3 days and then apply first application of Sencor and then follow the recommended 7-10 days before the next application. If in between, apply first application of Sencor, then wait 4-5 days, apply Assure, wait another 4-5 days then apply second application of Sencor.
Q: Sencor on a lentil field, growers main concern is the volunteer canola. He is aware that Sencor will get volunteer canola but wanted to double check that Clearfield fell under the volunteer canola. If it does what is the timing and rate?
A: Yes, Clearfield is the same as other volunteer canola, timing: lentil vines less than 15cm long, 3-5 node stage (4") and rate of 111g/ac.
Q: How much AMS do I need to add with Tundra?
A: 0.5 L/acre.
Q: What is the staging of Tundra?
A: 1-6 LS, up to the 3rd tiller.
Q: When is it too late to be spraying Tundra on Barley?
A: The correct staging for spraying Tundra on Barley is between the 1 -6 leaf stage and a maximum of 3 tillers.
Q: What is the tank mix order for Varro and Curtail M on spring wheat?
A: 1. AMS
3. Curtail M
Q: What can be used with Velocity M3 to control stork's bill?
A: To maximize activity of Velocity M3 on stork's bill add AMS and 2,4-D Ester at 4 oz.
Q: Can my CWRS, which was sprayed with Velocity, be underseeded to clover?
A: No, expect the clover to be injured. We would not expect a very high survivability.
Q: Can I leave Velocity in my tank overnight (rain delay)?
A: Yes, you can. Agitate every 6-8 hours. Store out of direct sunlight. Agitate well before spraying.
Q: When do you add MCPA to Velocity & AMS tank mix?
A: 4 oz/ac of MCPA can be added for increased suppression of Canada thistle, dandelion or perennial sow thistle. The addition of MCPA Ester may result in reduced grass control under drought conditions, heavy grass populations or advanced grass stages. In spring & winter wheat include AMS adjuvant when adding MCPA Ester.
Q: Should I be adding AMS to my Velocity?
A: This decision is based on many factors: temperature, target weeds, staging and density of weeds as well as the potential tank-mix of MCAP or 2-4D. AMS helps under cooler conditions and tough weed pressure, especially wild oats, cleavers and dandelions. If adding 4 ounces of MCAP or 2-4D, then it is required. Under warm humid conditions the AMS will heat up the mix and may cause some crop response. Please speak to your local TSM.
Q: What is the maximum temperature for spraying Velocity?
A: Do not apply to crop that is under stress due to abnormal environmental conditions such as frost, extreme heat, low fertility, drought, flooding, or disease and/or insect damage as crop injury may result. If temperature is over 30°C, advise the grower to contact their TSM to discuss options. Adding more water and avoiding the addition of any extras to the tank will help mitigate spraying in warm weather.
