Other Common Problems About Kaffir lime

Leaf yellowing is a common disease in Kaffir lime, causing its leaves to turn yellow and eventually shed. Despite not being highly lethal, it significantly affects the plant's photosynthesis process and overall health, often leading to stunted growth or plant death if untreated.

Large spot mold

Large spot mold is a foliar disease affecting Kaffir lime leaves, causing aesthetic damage and potentially reduced photosynthesis. It is identifiable by large, discolored patches on leaves.

Non-base branch withering

Non-base branch withering is a nematode-caused disease that greatly reduces the resilience and productivity of Kaffir lime, leading to wilting and eventual death of non-base branches. This disease majorly impacts the plant’s health, thereby reducing its overall efficacy and yield.

Yellow edges is a disease in Kaffir lime involving noticeable yellowing of leaves' perimeter. This condition results from nutrient deficiencies, physiological stress, and pathogens negatively impacting the plant's photosynthesis and general health.

Leaf rot is a significant disease affecting Kaffir lime, causing wilting, yellowing, and decay, and potentially leading to plant death. Produced mainly by the fungus, Pythium splendens, an understanding of its nature, symptoms, and control measures is critical for maintaining healthy Kaffir lime plants.

Psyllid disease, primarily caused by Diaphorina citri, notably affects Kaffir lime, leading to stunted growth, leaf curling, and potential fruit loss, disrupting commercial and personal cultivation.

Leafminer stripe

Leafminer stripe is a pathological condition affecting the plant Kaffir lime, characterized by visible narrow, silvery lines or stripes on leaves. Infestation severely impacts the plant's photosynthetic ability leading to stunted growth and reduced yield.

Stem cracking is a disease that severely affects the Kaffir lime. It causes cracking of the plant's stem, leading to weakness, reduced growth, and eventually plant death if not timely treated.

Scale insects are pests that infest Kaffir lime, causing yellowing leaves, stunted growth, and reduced fruit quality. These pests suck sap from the plant, excreting honeydew that promotes sooty mold growth, further damaging the plant.

Wilting in Kaffir lime is a devastating disease that causes drooping and browning of the plant, severely impacting its health. The disease is induced by a bacterial microorganism and worsens during high temperature and humidity conditions. Early detection and treatment can minimize its deleterious consequences.

Leaf white mold

Leaf white mold is a destructive disease affecting Kaffir lime, causing significant yield reductions and aesthetic damage. The fungal pathogen responsible, Sclerotinia sclerotiorum, manifests in white, fluffy mold growth and wilted leaves, primarily during cool, wet weather conditions.

Dark spots on Kaffir lime leaves and fruits signify a common disease affecting its aesthetic and commercial value. This disease can impair photosynthesis, weaken the plant, and affect fruit quality.

Fruit rot is a fungal disease posing serious threats to Kaffir lime. It is capable of destroying the entire plant's yield, altering fruit shape and taste, and can cause a total loss if not mitigated promptly.

Leaf malformation

Leaf malformation is a typical disease affecting the Kaffir lime, causing distortion, curling and yellowing of the leaves. This disease slows the plant's growth, affects foliage, and can ultimately impact fruit production.

Interveinal yellowing

Interveinal yellowing is a disease that affects Kaffir lime, hindering its growth and reducing fruit production. The disease is characterized by yellow strips appearing between the veins of leaves, which can eventually result in the plant’s death if left untreated.

Black mold is a fungal disease that affects Kaffir lime leaves, causing discoloration, reduced photosynthesis, and potential defoliation. Severity depends on environmental conditions and the plant’s health.

Whole leaf withering

Whole Leaf Withering is a plant disease that notably affects Kaffir lime, leading to the widespread wilting and eventual death of the leaves. This phenomenon decreases photosynthesis rates, stunts growth, and eventually proves fatal if untreated.

Leaf spot is a disease affecting Kaffir lime or Makrut lime, caused primarily by fungal or bacterial pathogens. This ailment leads to discoloured and mottled leaves which can affect growth, and in severe cases, can result in defoliation leading to diminished fruit production.

Dark blotch is a fungal disease affecting Kaffir lime, leading to reduced fruit quality and plant vigor. It primarily manifests as irregular dark spots on leaves and fruits, potentially impacting commercial value.

Brown spot is a fungal disease that affects Kaffir lime causing significant productivity loss. The causal pathogen, Cochliobolus miyabeanus, results in prominent leaf and fruit spots, that can lead to premature fruit drop and reduced yields. Control measures focus on fungicidal treatment and regular pruning.

Crown gall is a disastrous bacterial disease causing tumor-like growths on Kaffir lime's roots and stem base. It hampers the plant's growth, vigor, and productivity significantly, making it susceptible to further infections and eventually leading to its death.

Aphids, particularly the Asian Citrus Psyllid, cause significant harm to Kaffir lime, transmitting the lethal Huanglongbing (HLB) or citrus greening disease. This results in severe economic losses and challenges in citrus cultivation.
