Proper management needed to stop pests harming mango crop – Dr. R.K. Tomar

Lucknow: Director Horticulture, Dr. R.K. Tomar has said that from the point of view of ensuring good productivity of mango in the state, it is necessary that proper management should be done to protect the mango crop from contemporary harmful pests. The months of November and December are very important, in this month the outbreak of gujia and midge pests starts, causing great damage to the crop.

Horticulture and Food Processing Department, U.P. advises the gardeners to control the type and outbreak of the pest, that the babies of the Gujiya insect come out of the ground and climb on the trees and cause damage by sucking the juices from the soft leaves, manjaris and fruits. Its baby insects are 1-2 mm long and light pink in color and the female adult insects are white in color, wingless and flat.

For the control of this pest, deep ploughing / hoeing of the orchards should be done and 400 gauge polythene sheet at a height of 50-60 cm from the ground on the main trunk of the mango tree in the month of November-December to prevent the baby insect from climbing on the trees. Wrap a 50 cm wide band around the stem and tie it with twine at the top and bottom and apply grease on the upper and lower part of the polythene sheet so that the insect cannot climb on the trees.

Apart from this, to kill the babies on the ground, chlorpyriphos (1.5 percent) powder should be sprinkled around the trunk at the rate of 250 grams per tree twice at an interval of 15-15 days from the last of December or the first week of January. In case of severe infestation, if the pests climb on the trees, then spray Monocrotophos 36 EC 1.0 ml or Dimethoate 30 EC 2.0 ml solution per liter of water and spray as needed.

The Director of the Horticulture said that similarly, the midge, which occurs in the mango blossom, lays eggs in the flowers and fruits and later in the soft buds, whose nectar is eaten inside and damages it. For the control of this pest, it is necessary that the orchards should be plowed / hoeing and insecticides should be sprayed from time to time. For this, one spray of Phenitrothian 50 EC 1.0 ml or Diazinon 20 EC 2.0 ml or Dimethoate 30 EC 1.5 ml per liter of water is recommended and one spray at the flowering stage is recommended.

The director of the garden told about the precautions to be taken in the use of insecticides that the containers of insecticides should be kept away from the reach of children and animals. While spraying insecticide, gloves, mouth mask and eyes should be covered by wearing glasses, so that the insecticide does not get into the skin and eyes. Spraying of insecticide should be done in the evening when the wind speed is not high or should be done standing in the opposite direction of the wind. Empty insecticide pouches/cans should be buried in the soil.
