Citrus trees - Whitefly & Sooty Mould

Updated: Jun 25, 2019

The most common infestations that occur on citrus trees are Whitefly and Sooty Mould.

These are easily distinguishable and this blog post will cover the best methods of controlling them.

Whitefly can be distinguished as a small, white, hairy looking bug that lives on the underside of the leaf and secretes a honeydew which in turn creates Sooty mould. Sooty mould can be harmful to the tree due to loss of photosynthesis from the mould blocking the leaves from the sun. For control of Sooty Mould you will need a copper based fungicide such as Yates liquid copper fungicide available at places like Bunnings or Mitre 10.

Whitefly are a sap-sucking insect that operate in large numbers and if left unchecked, can do serious damage to your citrus trees. Whitefly control can be difficult as they are able to rapidly reproduce and quickly build up a resistance to regular chemical spraying. The best method is always prevention and you can protect your plants with a systemic insecticide such as Yates Super Shield before they become a problem.
