Hydrogen Cyanamide and copper compatibility
During August the use of Hydrogen Cyanamide (often referred to as Hi-Cane) as a bud-break enhancer increases. It is recommended that copper is not applied within a week either side of the application of a bud-break enhancer to avoid potential phytotoxicity issues.
Growers are reminded that strict conditions apply when using Hydrogen Cyanamide to comply with Council air plans. This includes notifying neighbours at lease 12 hours prior to the application of Hydrogen Cyanamide, clear signage must be displayed at orchard entrance and low-drift spray technology is now compulsary.
