The insect pest that causes these deformed leaves is the citrus leaf miner, pictured above. It’s a small moth that lays its eggs on tender new foliage. These eggs hatch into larvae that tunnel into the leaves, creating silvery trails and causing the leaves to distort. It ruins the look of a tree and in severe cases affects plant health by reducing the potential for photosynthesis (capturing energy from the sun).
Citrus trees start growing their flush of new foliage in early spring. New growth needs to be protected from citrus leaf miner attack by spraying the leaves with Yates® Nature’s Way® Citrus & Ornamental Spray. It deters the citrus leaf miner moth from laying her eggs on the foliage, thus preventing the damage caused by the tunnelling larvae. To protect citrus from leaf miner, spray leaves every 5-14 days from when the new foliage is around 4cm long.
Yates Nature’s Way Citrus & Ornamental Spray will also control aphids, which are attracted to tender new citrus leaves. Aphids are small sap sucking insects that can be green, brown or black and can cause leaves to curl under and twist. Like citrus leaf miner, the damage caused on new leaves by aphids is permanent. It’s easy to control aphids on citrus by spraying the foliage with Yates Nature’s Way Citrus & Ornamental Spray, including on the undersides of leaves where aphids often hide, every 5–14 days.
