The key to successful disease protection with copper is two words – foliar coverage.

Plant surfaces need to have a complete coverage of copper fungicide to defend the plant against infection. Copper fungicides work by preventing spore germination and can act at several stages in the fungus development. Any plant surface left untreated remains a potential disease infection site. Coverage is far more important than the quantity of actual copper on the plant surface.

The ultra fine particles of Nufarm’s Tri-Base Blue, where 75% of particles are less than one micron, provide a greater surface area than alternative products with larger particles. This allows the copper to exert its full potential against fungi and bacteria.
