How to control Meyer lemon tree disease

Meyer Lemon Tree disease can be put into 5 categories

  • Bacterial diseases
  • Viral diseases
  • Fungal infections
  • Mold growth
  • Rot

Bacterial diseases: Like citrus blasts can be spread by the wind.

Viral Diseases: Like citrus tristeza is damaging to different species of citrus trees.

Fungal infections: Like greasy spot can infect lemons to the point where they can’t be harvested.

Mold growth: Like sooty mold which is a black substance that forms on and covers the leaves, stems, and fruits, sooty mold looks like black dirt. This mold is influenced by the secretion of sucking insects such as scales, whiteflies, mealybugs, and thrips. The secretion encourages the formation of this black mold known as honeydew.

Sooty mold: Not only makes plants look unattractive and sickly but may also interfere with photosynthesis the process by which plants manufacture their food. Eliminating the insects that encourage sooty mold to form will bring control.

Rot: Like foot rot is caused by a micro-organism called Phytophthora that is brought on by soils that are too wet, Phytophthora is most damaging when citrus roots are inactive and their resistance to infection is low. Once the roots are infected they begin to rot.

Signs of  Meyer Meyer Lemon Tree Diseases

Foot Rot: Signs of foot rot disease show up as lesions near the grafted bud union, with a lack of tree fruiting.

Citrus Blast: Affects the south side of the tree and shows up as scabs and black spots on the fruits.

Greasy Spot: Leaves black specks on the fruit rinds.

Greasy spot can be controlled by liquid Cooper spray fungicide application. The tree should be sprayed first in June or July and a second application in August or September.

  1. Great article with all the information needed to take care a Meyer Lemon tree. The categories of the disease give me a clear picture how the Meyer Lemon tree is suffering if we do not care well.

    Bacterial diseases spread by the wind can be hard to do any prevention and probably needs to see some sign before control can be applied.
