Key messages

• Angel has excellent tolerance to sulfonylurea (SU) herbicide residues (including summer SU herbicide applications)
• Angel can be controlled in-crop by a range of commonly used herbicides
• Angel is the world's first annual pasture legume tolerant of SU residues
• Angel seed available in 2006 in limited commercial quantities

Summary

A new annual medic, Angel*, has been bred from Herald strand medic ( M. littoralis ) by John Heap, SARDI and Chris Preston (CRC for Weed Management Systems) using conventional mutation breeding. Extensive field testing has confirmed its excellent tolerance to a range of sulfonylurea (SU) herbicide residues. We believe it to be the world's first annual pasture legume tolerant of SU residues.
