Weed and insect control from pre-seed to harvest



FMC has canola growers covered from pre-seed to post-harvest with products that control weeds and insect pests in canola.

Pre-seed herbicide options from FMC

Pre-seed weed control is critical to maintaining yield potential in canola. Using multiple modes of action, including a burnoff, extended control or a combination of both in your pre-seed application is particularly effective at reducing weed populations. It’s also going to take more proactive strategies as part of an integrated pest management system as cases of herbicide resistance proliferate in problem weeds.

Command® Charge herbicide is unique, offering both Group 13 and Group 14 activity. It gives growers a good opportunity to introduce different modes of action into their crop rotation to manage resistance. When tank-mixed with glyphosate it provides an even broader spectrum of weed control before canola, plus top-notch resistance management.

Command® 360 ME herbicide is a great choice for extended pre-seed weed control. It can be tank-mixed with glyphosate, or Aim® EC herbicide + glyphosate for enhanced control. Command® 360 ME herbicide uses Group 13 activity to control flushing cleavers, suppress chickweed and fight resistance before canola.

Aim® EC herbicide is a strong Group 14 glyphosate partner for enhanced burnoff prior to all major crops including canola, cereals and pulses. Watch the fast Group 14 action improve control of tough to kill weeds like kochia and cleavers (including resistant biotypes), flixweed, lamb’s-quarters and redroot pigweed.

In-crop insect control

There are effective insecticide seed treatments to protect canola, but if the weather turns and seed stays in the ground too long before germinating, the clock can run out on your seed treatment’s efficacy against flea beetles. It’s important to protect your canola if it hasn’t reached the three- to four-leaf stage and flea beetles are feeding.

Pounce® 384EC insecticide is a high performing solution for flea beetles in canola, controlling both striped and crucifer flea beetles, as well as cutworms. It’s an effective foliar solution to support canola seed treatment packages and is registered for both ground and aerial application.

Later in the season, insect pests like grasshoppers, bertha armyworms and diamondback moth can cause significant damage to yield and quality. At this point in the season, you can turn to other products in the FMC portfolio, like Coragen® MaX insecticide.

Coragen® MaX insecticide powered by Rynaxypyr® active formulation is 3X more concentrated than Coragen® insecticide, so you cover more ground with less product. It provides all the benefits of the original Coragen® insecticide with extended control of key insect pests like grasshoppers, bertha armyworms, diamondback moth and cutworms. And it has minimal impact on many important beneficial insects*, allowing them to continue their work.

With Coragen® MaX insecticide there is less product to handle while mixing, a smaller footprint in the chem shed or shop, and less plastic and packaging waste to dispose.

Post-harvest herbicide application

There are four really good reasons to prioritize a fall herbicide application.

First, a fall herbicide application conserves water. According to a University of Nebraska Lincoln study, it takes 800 lbs of water to produce one pound of winter weed mass. One acre can produce 500 lbs in winter annual weed biomass by spring planting. That means 1.75 acre-inches of soil moisture is lost by seeding. Manage the fall weed growth and conserve soil moisture.

Second, a fall application can also help preserve readily available nitrogen in the soil that wasn’t fully used by the last crop.

Third, if flea beetles are present in the field at the end of the season, a fall application helps ensure they can’t feed off, or seek refuge in plant residue over the winter.

Fourth, a post-harvest herbicide application is an excellent way to control winter annuals and biennials. Perennial weeds use that post-harvest period to move nutrients into their root systems. Use this natural flow to your advantage with a fall herbicide application.

Express® brand herbicides https://ag.fmc.com/ca/en/fall-herbicides/express-sg-herbicide-west-fall ] provide powerful systemic control that enhances the activity of glyphosate on tough biennial and perennial weeds.  The systemic movement is supported even more in the fall as weeds move their nutrients down into the root system - ensuring there is control right from the shoots to the roots with no regrowth. Express® FX herbicide provides effective resistance management and control of resistant kochia, dandelion and more.  Express® SG herbicide controls dandelion, volunteer canola and narrow-leaved hawk’s-beard.  Speak to your local retailer or FMC representative before applying Express® brand herbicides in the fall prior to canola.  

*When applied at label rates. In line with Integrated Pest Management and Good Agricultural Practices, insecticide applications should be made when pollinators are not foraging to avoid unnecessary exposure.
