Citrus Bud Mite

These little mites cannot be seen with the naked eye. Citrus bud mites live in the flower and leaf buds. They don’t like hot and dry conditions. This microscopic mite is a tiny 0.17mm in length, creamy colour and worm-like.

Plant Part: Blossoms and leaves

Season: Autumn

Symptom: You may notice rosette-like growth of leaves at the tips, blackening of the buds and distortion of flowers. Feeding damage to developing fruit causes fruit deformation. There will be no gum staining or branches dying off.  Lemons and navel oranges are especially susceptible.

Control: Applying a white/pest oil when your citrus tree is coming into flower may help or you can apply wettable sulphur two to three months before the bloom that is to be protected. Control can be difficult as the mite is protected within the leaf or flower bud.

Preventative: Encouraging beneficial bugs to your garden will help control this little mite. They travel in the wind.
