Sudden death in mango

Ceratocystis fimbriata, Fusarium, Lasiodiplodia theobromae, Nattrassia mangiferae,
Pakistan

Recognize the problem

The first sign of the disease is the oozing of the bark. This is followed progressively by the development of cankers on the trunk, rotting and blackening of the bark, the splitting of the trunk, and the drying and curling of twigs and branches. Finally, the leaves are shed from the tree.
Collapse of mango plants occurs within a couple of days because of its quick decline. This disease has 100% mortality.

Background

This is a very destructive disease of mango trees in Pakistan. This syndrome of mango is a complex problem and is actually the result of a particular mix of fungi resulting in die back, root rot, tip dieback, gummosis and drying and dying of trees.
The disease can remain in dead trees for a long time, and enters the tree via cuts and injuries made by unclean equipment, bark beetles and other mango tree bark feeding insects.

Management

  • Keeping trees healthy and avoiding water stress will help to prevent the trees from succumbing to the disease
  • Regular monitoring of orchards is important in identifying the problem at an early stage
  • Application of  Bordeaux mixture twice a year helps to reduce the fungal inoculums (sources) on the tree
  • The diseased trees should be removed and burnt
  • Control bark beetles or caterpillar borers by applying bifenthrin (e.g. Talstar) or permethrin 200 cc in 100 litres of water
  • Annual spray: thiophanate-methyl (e.g. Topsin-M) or Pre-Cure @2.0gm/lit. of water can also be scheduled as follow:   
    • First spray during the last week of February
    • Second spray before the onset of monsoon rains
    • Third spray after the rainy season

When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
