Phytophthora is a genus of plant-damaging water moulds, which cause economic losses to crops worldwide and environmental damage in natural ecosystems.
Risk management in nurseries is focused on an integrated approach to prevent Phytophthora from entering the nursery and its subsequent spread through the production cycle through to planting out.
It is necessary to adopt an entire clean production system to achieve the goal of producing healthy plants, this includes a high standard of nursery hygiene: clean stock, clean soil, clean water.
