PEST SYMPTOMS TREATMENT

 Powdery mildew

 The backs of the leaves are covered in white mold, appearing as if they have been smeared with flour. 


Prevent the condition by placing plant in a sunny spot with good air flow. If it occurs, apply a solution of anti-mildew agent. 

Sooty mold Branches, 

leaves and the surface of the trunk appear to be covered with soot. This is caused by mold which lives on the excrement of aphids and other pest insects.


 Applying an agent to kill pest insects will prevent this condition. Leaf spot disease Small brown spots appear on the leaves, causing them to change color. This is commonly caused by mold.


 If spots appear, remove the affected leaves and apply a solution to treat the condition.

 Aphids

 Starting with new buds on small trees, these insects infest the entire plant, consuming the sap and impeding the development of the tree. If an infestation occurs, use a brush to lightly knock off insects and apply an appropriate solution.

White spots

 appear on the fronts of leaves and the leaves lose their color.

 Mites thrive in high temperatures and dry conditions, so wet the backs of the leaves. If an outbreak occurs, apply an appropriate solution. 

Scale insect 

These insects appear on bark and stalks, sucking the tree’s sap. Use a brush to lightly knock off insects and apply an appropriate solution.
