Diagnosing glyphosate damage in field peas

Glyphosate is a systemic knockdown herbicide that is used extensively for brown fallow, summer weed or pre-seeding weed control, or selective weed control in glyphosate resistant crops.

The first sign is yellowing/ reddening and sometimes interveinal chlorosis of new growth
Tendrils and leaves become wilted and necrotic and the plant dies

What to look for

    Paddock

  • Limp discoloured plants that may slowly die.
  • Direct spray damage is uniformly distributed but varies with spray coverage on overlaps or boom turns.
  • Spray drift damage is worse near the source.

    Plant

  • The first sign is pale new growth that may contain red colours and have interveinal chlorosis.
  • Chlorotic areas become necrotic and the plant wilts and dies.
