Pests and diseases
This page can help you identify and manage pests and diseases common to mango crops in the Northern Territory (NT).
Integrated pest management can also help your orchard.
A major disease in wet years, this fungus causes black spots on leaves and fruit.
Read the Agnote mango anthracnose (2007)
Bacterial black spot
This disease attacks mango leaves, twigs and fruit.
Read the Agnote bacterial black spot of mangoes (2006) .
This is a fungus that causes black spots on new fruit. In severe cases, numerous lesions can cause new shoots to defoliate.
Unlike anthracnose, scabs do not expand after harvest, nor develop into a rot. However, severely scarred fruit will show post-harvest anthracnose rot earlier than non-scarred fruit.
Read the Agnote mango scab and its control (2007) .
Adult false mango scale and white mango scale insects suck sap from mango plants, turning leaves yellow and leaving pink blemishes on fruit.
See the managing mango scale post which illustrates this insect and its life cycle.
When this yellow-brown fly lays eggs under the skin of the mango, its larvae introduces bacteria and causes the fruit to breakdown and rot.
Read the Agnote field spraying of mangoes 1998 for recommendations on spray equipment and spraying rates to protect against fruit fly.
Leafhoppers are four to five millimetre long insects that lay eggs on the underside of young mango leaves. They suck sap from plant tissue and flowers, causing withering and failure to fruit.
Read the Agnote mango leafhoppers (2014) .
Mango seed weevil
Weevils attack mango seeds. This can downgrade the fruit and severely reduce germination.
View the poster managing mango seed weevil which illustrates the life cycle of the weevil.
