Pests that make webs can cause heavy damage to mango orchards, farmers should not ignore and take immediate measures

A lot of webs are being seen in the mango orchard these days. In small orchards, the eyes of the farmers fall on them and they make arrangements to deal with it, but in big orchards it is not noticed. In such a situation, it causes huge loss to the farmers. In recent years, nets have had a significant impact on tree health, including yields in orchards. It is actually caused by the beaver containing mango leaves. If farmers do not dispose of it at the right time, then along with the quality of mango, there is a direct impact on the orchards. Especially in areas with moisture, they prove to be more dangerous.

Earlier it was considered a less dangerous pest for mango, but since last two years this pest has become a major pest in Bihar causing damage to mango. This insect is very active every year from the month of July and continues to cause damage till December. The leaf webber insect lays eggs on the leaves, which is extremely dangerous for mango trees and fruits. This affects both quality and production.

inflicts damage like this

According to senior fruit scientist Dr SK Singh, farmers should not make the mistake of taking the spider web lightly. It is harming mango trees as the most dangerous disease. The leaf webber moth lays eggs on the leaves, which feed on the leaves by cutting into the epidermal surface upon hatching over a week’s time, while the other insta larvae begin to burrow off the leaves and feed on the entire leaf. In the month of May, when new leaves are coming out, this pest can also be seen at this time. This pest takes a more dangerous form in those gardens which are not managed properly.

How to take care

  • Cutting the nets using any tool reduces the vigor of the insect.
  • Thereafter, spray Lambadiostrin 5 EC (2 ml per liter of water).
  • After 15-20 days of first spray, second spray with either Lambdacylotrin 5 EC (2 ml/Lit of water) or Quinalphos 25 EC (1.5 ml of water) should be done.
  • This pest can also be managed by spraying insecticides such as indoxacarb (1.5 ml per liter of water) or emamectin (0.4 g per liter of water).
  • Spraying of Bacillus thuringiensis is also recommended if there is an organically managed garden.
