Citrus Collar Rot
Presenter: Judy Horton
Episode: 22 (22nd September 2007)
A nasty problem that affects lots of citrus is called collar rot. It causes wet, gummy patches on the bark that can eventually spread and ringbark the tree. If you see this problem it’s important to do something about it.
Start by trimming the branches so that a bit more sunlight and air can get into the base of the tree. Cut away the loose bark with a sharp tool and then paint the affected area with a slurry made by mixing a copper fungicide with water.
Check that your citrus are getting plenty of sunlight and have good drainage. If they don’t, you may have to consider starting again.
Fortunately a once-a-year spray with Yates Anti Rot all over the leaves can help citrus plants to resist this disease.
Finally, keep weeds and grass away from the base of your citrus trees and mulch the root area with a good layer of organic matter. Never let the mulch come into direct contact with the trunk. Always leave a breathing gap of at least five centimetres.
