Herbicide residues after drought
Released/reviewed: Dec 2006
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.
