Rapeseed Cover Crop Plant

Rapeseed is a cool season winter annual in the brassica family used in many cover crop mixes. It is easy to establish via drill, broadcast, or aerial application is fast growing in the fall, and has a fibrous root system that helps break compaction. Rapeseed can be planted later than radishes, and will often survive the winter to continue soaking up nutrients in the spring. If spring termination is necessary be sure to use 2,4-D or Sharpen in a mix, Roundup will not kill rapeseed by itself.

Key Benefits

  • Strong winter-hardiness

  • Suppresses disease (like white mold)

  • Easy to establish

  • Suppresses Sudden Death Syndrome

Herbicides To Avoid

Corn

  • Atrazine or simazine at >1 lb will be problematic for legumes and mustards unless lots of rain

    • <0.75 lab/A may allow for most legume cover crops, mustards, and annual ryegrass.
    • Atrazine < 1 lb/A can allow cereal grain establishment
  • Mesotrione (Callisto, Lumax, Lexar etc.), flumetsulam (Python) and clopyralid (Stinger, Hornet, SureStart) can be problematic for legumes and mustards like canola and forage radish.

Soybean

  • Chlorimuron (Classic, Canopy, Cloak, etc.), Imazethapyr (Pursuit), and fomesafen (Reflex etc.) could be a problem for fall seeded legume or mustard covers including radish.  However, establishment of cereal grains should be OK.
