BARGUNA, Oct 21 (BSS): Light-trap, an environmentally sound method for detecting harmful insects, is helping the farmers in different areas of the district during the current Aman season.
This eco-friendly 'light-trap' method as an alternative to pesticides control, getting popular among the farmers at different villages as they are attaining significant success in pest management on transplanted Aman paddy.
The farmers set the light-traps at night with kerosene lamp, charger light or electric bulb and place a pot with detergent or kerosene mixed water under the light. The light attracts the insects that die after falling into the pot. If existence of harmful insects is found, experts advise the farmers to adopt effective pest control method.
"In 30 blocks under 10 unions within my jurisdiction, farmers did not have to use any pesticide so far this year because they did not detect any harmful insects in the paddy fields through the light-trap method," said Badrul Alam, Amtali upazila agriculture officer.
Officials of the Department of Agricultural Extension (DAE) said, they have introduced the programme throughout the district to detect the harmful insects in the Aman fields and use the insecticides accordingly to save the crops.
The low-cost method is also helpful for maintaining ecological balance in the fields. They also said the farmers are extremely enthusiastic in using the method because they are reaping benefit from it.
Normally farmers apply costly insecticides in the paddy fields indiscriminately, killing all the insects including the useful insects, and causing a definite environmental degradation. But when the harmful insects are detected through the light-trap method, they can save money by applying a cheaper insecticide to kill that particular pest as per the experts' suggestion, said the officials.
Over 1,50,000 hectares of land have been brought under Aman cultivation in the district this year. Around 3,000 light-traps have already been set up in the district.
