Cleavers are bad enough to begin with. The fact they can also resist some herbicides is almost unfair.
If prairie farmers apply the same tired modes of action throughout the season, year after year, we’ll continue to struggle against cleavers. Long term, resistance wins.
The solution is new modes of action and a new pattern of application. It’s called herbicide layering.
Herbicide layering is the practice of using multiple herbicide groups and active ingredients at different application timings to control the same resistance-prone weeds.
Start with a pre-seed herbicide application with a weed control product that delivers both a fast burnoff and extended control. Post-emerge, apply one or more herbicides with different modes of action. Over the length of the growing season, you put two, three or even four different modes of action down. That’s the way to get excellent control – even of weeds resistant to certain herbicides – and delay resistance-prone weeds from going over to the dark side.
For cleavers in canola, go early and go hard. Command® Charge herbicide combines Group 13 and 14 action for outstanding resistance management. Command® Charge herbicide offers an extensive broadleaf burnoff label – with extended activity on cleavers and chickweed -- in all herbicide-tolerant canola systems.
