Mango Blossoms: How to Control Black Mango Blossoms and Jassid Insect in Mango Crop
Mango is one of the most delicious fruits in the world, and it is extensively cultivated in tropical regions. Apart from being a tasty fruit, it is also beneficial as it is a good source of vitamins and minerals. However, mango crop is often attacked by pests which are responsible for a decrease in yield and quality of the fruit. Two of these pests are black mango blossoms and jassid insects. This article will discuss the identification, causes, and methods of controlling these pests.
Identification of Black Mango Blossoms and Jassid Insects
Black Mango Blossoms are characterized by their black, irregularly shaped patches which appear on the blossoms. These patches are typically black or dark brown in color, and they can spread rapidly, infecting all the flowers on the tree. In some cases, the entire mango tree can be affected, leading to significant yield loss. On the other hand, Jassid insect is a small, greenish-yellow caterpillar that feeds on the sap of mango leaves. It causes yellowing or discoloration of the leaves, which eventually leads to defoliation and a decrease in fruit yield.
Causes of Black Mango Blossoms and Jassid Insects
The primary causes of black mango blossoms are fungal infections such as anthracnose and bacterial infections such as bacterial canker. These infections can be carried by wind, insects, and water splashes. They thrive in warm, moist environments and affect plants with a weak immune system. As for jassid insects, they are attracted to warm, humid climates and can be found in large numbers during the monsoon season. They feed on the sap of the mango tree, depriving it of essential nutrients and causing significant damage.
Methods of Controlling Black Mango Blossoms and Jassid Insects
1. Cultural controls: One of the most essential steps in controlling black mango blossoms and jassid insects is to maintain good orchard hygiene. This includes pruning branches that are diseased or infested with insects and removing fallen leaves or fruits from the orchard. Additionally, farmers must regularly aerate the soil around the base of the tree to prevent waterlogging.
2. Chemical controls: The use of chemicals such as fungicides, insecticides, and miticides can be effective in controlling black mango blossoms and jassid insects. However, it is necessary to use proper protective gear when applying these chemicals to prevent exposure to toxic substances.
3. Biological controls: The use of biological control methods such as the release of natural predators and parasites can be an effective way of controlling jassid insects and other mango pests. This approach requires less chemical usage and is more environmentally-friendly.
Conclusion
Black Mango Blossoms and Jassid Insects are two significant mango pests that can cause significant yield loss if not controlled properly. Maintaining a good orchard hygiene, using chemical and biological controls, and ensuring the mango tree has a good immune system can help control these pests. By being vigilant and following proper pest control techniques, farmers can increase the yield and quality of their mango crop.
