Agriculture Department Commissioner Kanhaiya Lal Swami has given instructions regarding the outbreak of Chempa in the mustard crop. The Commissioner said that due to fluctuations in weather, the possibility of the occurrence of Chempa (Moyla) pests in mustard crops increases in January. When the average temperature is 10 to 20 degrees Celsius and the humidity is high, there is a possibility of the spread of Chempa insects, which affects the crop yield of the farmers.
He said that if farmers do not prevent these pests, there is a possibility of a significant reduction in crop yield. Therefore, farmers have been given instructions for timely control by using pesticides as per the recommendation of the Agriculture Officer or Agriculture Supervisor.
As soon as there is an infestation of Chempa insect, if the number of Chempa is visible from 20 to 25 in about 10 cm length of the main branch of the plant within a week, then spray Malathion 5 per cent powder at 25 kg per hectare or Malathion 50 EC. One and a quarter litre or dimethoate 30 EC. Mix one-litre medicine in 400 to 500 litres of water per hectare and spray it.
The Agriculture Commissioner said that the outbreak of Chempa insects is more in January, in which the light green-yellow coloured insect lives in small groups on various soft parts of the plant, flowers, buds and twigs and sucks the juice. Due to the sucking of sap, the growth of the plant stops, buds become less and the number of pod grains also decreases, resulting in less yield.
