Herbicide residues after drought


Herbicide carryover problems are exacerbated in drought years due to reduced herbicide breakdown. This is of particular concern in alkaline soils.

Residual herbicides of concern include the group B herbicides (including the sulfonylureas, Broadstrike®, Spinnaker® etc.) and group C (e.g. atrazine and simazine) products.

Topics covered include:

  • herbicide carryover
  • herbicide information
  • herbicide breakdown
  • assessment.
