Answer: Hi Jamie,

Thank you for contacting Yates.

Yes, this is the correct information. Unfortunately, as yet we do not have a product for the control of citrus gall wasps. For the treatment of citrus gall wasps, we generally recommend cutting off the infected stem/branch below the infection, then fertilising with ‘Yates Thrive Natural Citrus & Fruit Organic Based Pelletised Plant Food’ to improve plant health and reduce pests and diseases.

However, if by cutting off the infected stems/branches means the death of the plant, you can either replace the plant, or, leave the infected stem as it is in hope that it will not be detrimental in the long term. The problem with leaving the infected stems are that the stem will never heal itself, but, it will grow new bark over the old tissue. This leaves the stem/branch hollow and causes a weak spot that may reduce the strength of the plant and/or provide a site of further infection by pests and diseases.

Hope this helps.
Joyful gardening!
Kind regards,

Yates Horticulturist
