Public asked to look out for Myrtle Rust

Myrtle rust, a serious fungal disease, is a threat to a number of New Zealand’s native plants. It was first detected in a Northland nursery in May and is believed to have arrived via spores from Australia. Severe infestations can kill affected plants in the myrtle family, such as pōhutukawa, kanuka and mānuka, and have long-term impacts on the regeneration of young plants and seedlings.

While there have not been any signs of myrtle rust in the Horizons region the public are asked to check their own gardens and planting areas. Symptoms to look for include bright yellow powder on both sides of leaves; it generally attacks soft, new growth, including leaf surfaces, shoots, buds, flowers, and fruit.

Council’s Parks and Reserves team have been educated to identify any plants with signs of myrtle rust and will not be purchasing plants from any of the affected areas.

If you believe you have seen myrtle rust on plants in New Zealand:

• Take a clear photo of symptoms and the host plant if possible
• Immediately call MPI on 0800 80 99 66
• Do not attempt to touch the plant as this may aid in the spread of the disease
