Oil spray adjuvants can be broken into sub-groups. Oldest technology is represented by mineral oil spray adjuvants (think of them as FJ Holdens). More recent developments include canola oil spray adjuvants (Protec Oil, Codacide, Synertrol) (Think of these as EH Holdens). The newest technology includes what are known as the “Esterified canola oil” spray adjuvants. (Think of these as the latest HSV Holdens.) These include Protec Plus, Promax and others. There are a range of qualities amongst these products, with some products specifying only “vegetable oils”. Some products may use old cooking oils that may be heat affected.
A number of labels may specify a mineral oil. Products include Uptake® Oil, Ad-here, CropShield, Enhance etc.
