Cahaba Vetch Cover Crop Plant

Cahaba vetch provides a means of supplying an excellent forage source in the eastern and southern parts of the US during summer months. It does not tolerate cold temperatures and will begin to die off around 20°F. As a summer legume, it can be used to follow wheat, bypass planting, to fix nitrogen, and provide a superior grazing or hay source. An added benefit to your cover cropping programs – Cahaba vetch can assist in controlling some nematode species.

Key Benefits

  • Increase nitrogen and soil organic matter

  • Erosion control

  • Resistant to races 3 & 4 of soybean cyst nematode

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.
