Dieback is spread in soil and water and
the BRM industry poses a significant risk of spreading this disease
e.g. by using road building material sourced from infested pits.

These best practice guidelines outline ways in which BRM producers
and suppliers can minimise the spread of Phytophthora Dieback, and provide advice on general considerations such as
Hygiene/Dieback Management Plans, Green Card Training,
Contractors, and Sales and Marketing. They provide specific guidance
for all stages in the operation of a mine or quarry.
