How to treat white spots on mango plant leaves?

balaji27

Hello Team,

Would you please check the pics of my mango plant and advise me what's the issue and how to fix it if there are concerns? I noticed lots of white spots, are they eggs or some infection?

Hope to get your expert advice.

Thanks

Balaji.

Hi @balaji27,

Thanks for sharing the photos of your mango plant.

The white spots you are seeing are scale insects. These are small sap sucking pests that attach themselves to the plant and can weaken it over time if left untreated.

To manage this, I recommend the following:

• Gently wipe or remove the visible scale with a soft cloth or sponge
• Apply a horticultural oil such as Seasol EarthCare White Oil Insect Spray, making sure to thoroughly coat the affected areas including stems and the underside of leaves
• Repeat the treatment every 7 to 10 days as needed to break the lifecycle
• Keep an eye on the plant for any reappearance.

Alongside this, improving the overall health of the tree, via consistent watering and the application of a slow-release fertiliser such as Scotts Osmocote Citrus and Fruit Controlled Release Fertiliser will go a long way towards preventing this in the future.

With consistent treatment, your mango plant should recover well.

Let me know if you have any further questions.
