The mango tree (Mangifera indica L) is a tropical fruit tree native to the region from India to Myanmar and has been cultivated for over 4,000 years. Today, mango trees are widely grown in 60 countries across tropical and subtropical regions with a very large production.

In our country, mangoes are cultivated in almost all provinces and cities nationwide, with a total estimated area of over 87,000 hectares. To date, Vietnamese-branded mangoes have been exported to 40 countries around the world, bringing high economic value to the people. Like other crops, mango trees often face the risk of being attacked by various pests and diseases, with anthracnose and powdery mildew being the most common diseases affecting mangoes. Let’s join Agrifuture to explore preventive measures for these harmful diseases in the following article.  

1.Anthracnose Disease

Pathogenic Characteristics

Anthracnose disease in mango trees is commonly caused by the fungus Colletotrichum gloeosporioides. The disease can affect the leaves, flowers, and fruits of the mango tree.

On leaves, the disease typically affects young leaves. Farmers may notice small, darkening spots the size of a pinhead that gradually enlarge into undefined shapes (usually oval or round, black in color). The disease can spread extensively, causing damage to the leaves, which impacts the tree's photosynthesis and nutrient synthesis processes.

On flowers, the disease causes them to drop and turn black, reducing the tree's yield.

On fruits, the disease can appear from when the fruit is small until harvest time, reducing the quality and appearance of the fruit. The fruit may become tough, misshapen, or even rot and fall off.

Preventive Measures

Agrifuture Company recommends using effective fungal disease prevention and treatment products such as TV AZOMIDE 25WP and TVZEB JAPANE 70WP.

• Product information for TV AZOMIDE 25WP:

Thuốc trừ bệnh TV AZOMIDE 25WP

Properties and Uses:

The unique and pioneering invention has led to the creation of TVAzomide 25WP, featuring a specialized fungus-killing mechanism that directly targets the mitochondria of pathogenic fungi by inhibiting succinate dehydrogenase and the ATP energy production process. This results in the immediate death of the fungi upon application. TVAzomide 25WP has strong systemic and translocation capabilities, ensuring rapid and comprehensive eradication of fungi.

Usage Instructions:

TV Azomide 25WP is registered for the control of anthracnose disease on coffee plants.

  • Application Timing: Spray twice, 7 days apart, with the first spray when the disease initially appears, at an infection rate of approximately 5-6%.
  • Dosage: 0.1%. Mix a 20g packet with 25 liters of water.
  • Water Volume: 500-800 liters per hectare. Ensure thorough wetting of the plant foliage.
  • Pre-Harvest Interval: 7 days.

Pre-harvest interval: 7 days after spraying.

1.Powdery mildew disease

Pathogenic Characteristics

The disease is caused by the fungus Oidium mangiferae and develops strongly in hot and humid weather or when there is dew in the evening. The primary sign to recognize an infected plant is the presence of a white powdery layer on young mango leaves and fruits. Initially, the disease appears on the flowers and then spreads to the leaves, leaf stalks, young fruits, and branches. Infected leaves will have reduced photosynthetic ability, infected flowers may fall off, and fruits that set can become misshapen and deformed, losing their aesthetic appeal. Fruits attacked by the white fungus will be distorted, malformed, unattractive in color, pale, dry, and prone to falling off, thus reducing yield and commercial value.

Control Measures

In addition to the two specialized products for anthracnose disease, TV AZOMIDE 25WP and TVZEB JAPANE 70WP, farmers can also use the product CAP JAPANE 70WP for effective prevention and treatment of powdery mildew and other fungal diseases. 

• Product Information for CAP JAPANE 70WP:
