Mango

Mango is a major tropical fruit tree. It is highly susceptible to micronutrient deficiencies like Zinc (Little Leaf) and Boron (Internal Necrosis/Fruit cracking), which affect fruit yield and quality.

Confused about plant symptoms? Nutrient starvation can mimic aggressive fungal blights. Check our Symptom Disambiguation Guide to tell them apart.
Soil pH Alert: Many deficiencies are chemically locked due to soil acidity or alkalinity. Read our global Soil pH Interaction Guide to check if you need soil correction before applying fertilizers.
Zinc Deficiency
Moderate Severity

Zinc Deficiency

Zincum Deficientia

Key Visual Symptoms

Leaves emerge extremely small, narrow, and clustered in a tight, rosette-like bundle at shoot tips (hence 'Little Leaf'). Leaves are thin and display interveinal chlorosis.

Organic Remedy
  • Incorporate zinc-solubilizing bio-fertilizers or well-rotted organic compost into soil.
  • Avoid excessive phosphorus applications, which block zinc uptake.
Chemical Correction
  • Foliar spray with 0.5% Zinc Sulfate (ZnSO₄) twice at 15-day intervals during new leaf flushes.
  • Apply Zinc Sulfate monohydrate to the soil basin at 100-200g per mature tree.

Boron Deficiency
Severe Severity

Boron Deficiency

Boron Deficientia

Key Visual Symptoms

Developing mango fruits crack open, secrete gummy ooze, and drop prematurely. Cutting the fruit reveals dark brown, corky, dead necrotic patches in the pulp near the seed.

Organic Remedy
  • Apply composted organic matter and avoid alkaline pH spikes.
  • Mulch to maintain steady soil moisture, preventing boron leaching.
Chemical Correction
  • Foliar spray with 0.1% Solubor or Borax during flowering and early fruit set.
  • Soil apply Borax at 50-100g per tree under the drip line.

Mango Diagnostic Guide: Diseases vs. Deficiencies

Rosette-like bunched leaves or dry margins on mango trees can represent disease or nutrient hunger. Diagnose correctly.

Zinc (Little Leaf) Rosetting
Nutrient Starvation
Zinc (Little Leaf) Rosetting
Key Indicators to Look For:
  • Leaf Size: Zinc deficiency causes 'Little Leaf' rosetting where leaves are severely reduced in size. Fungal powdery mildew covers normal-sized leaves in white spores.
  • Fruit Damage: Boron deficiency causes internal necrosis (brown corky centers) and fruit splitting. Diseases like Anthracnose cause black, sunken lesions on the fruit surface.
