A big, strong taproot! Combined with its perennial nature, the taproot makes dandelion a super villain.
A perennial weed with a large tap root, dandelions are sometimes present in early spring in time for pre-seed burnoff. The deep-lobed rosette stage is the most practical stage for control. If it gets past that stage, its familiar yellow flowers are easily recognizable. Dandelion is typically a bigger issue for those in dark brown to black soil zones.
HOW TO DEFEAT THIS VILLAIN
Canola – Roundup Ready® canola can help clean up a dandelion issue. Use Roundup Transorb® HC at 0.5 L to get season-long control.
Cereals – You have two possible approaches: 1. Balance the cost/recropping restrictions of a product like Prestige™ XC; 2. Take a multi-year approach if budget, crop rotation and urgency are issues.
Peas & Lentils - In-crop options barely brown dandelion.
- Canola: Use a tankmix partner with Roundup Transorb HC (0.5 L) at pre-seed burn. In the brown soil zone we recommending including Conquer® in your tank mix at pre-seed.
- Cereals: Cirpreme™ XC. In the brown soil zone use Blackhawk® or Express® FX tank mixed with Roundup Transorb HC at pre-seed.
- Pulses: Heat® LQ before pulses. In the brown soil zone, in addition to Heat LQ you can also use Goldwing tank mixed with glyphosate prior to lentils.
As with Canada thistle, use your best one-two punch to tackle dandelion. You can throw high rates of herbicide at it in the spring, but you’ll often need to hit them pre-harvest to really take them out.
As much as we talk about burning back dandelion with a pre-seed herbicide application, the best time to get dandelions in-crop is pre-harvest. That’s because it’s the best time for the plant to move glyphosate down to the roots as it prepares to overwinter.
Always read and follow label directions.
