Scientists and researchers concerned have viewed that eco-friendly rat management can be vital means of protecting many beneficial insects together with maintaining a sound environment.
They have revealed that the farmers destroy various species of the insects during the time of eliminating the destructive ones due to lack of adequate knowledge in this regard.
The farmers conventionally apply rodenticide killing many non-target beneficial animals and birds, they say.
They were addressing a daylong farmers training on the issue of eco-friendly integrated pest management.
Vertebrate Pest Management Division of Bangladesh Agriculture Research Institute organised the training at its local station of On Farm Research Division (OFRD) in Rajshahi on Thursday.
National Agricultural Technological Project under the Bangladesh Agriculture Research Council financially supported the programme with the main thrust of disseminating modern practical knowledge among the farmers so that they can manage rats in a eco-friendly integrated way.
VPMD principal scientific officer Shah Alam, principal investigator of the project ATM Hasanuzzaman, OFRD senior scientific officer Nur-E-Alam Siddiqui and its scientific officer Jahedul Islam conducted the training sessions as resource persons disseminating their expertise on the issue.
Shah Alam says integrated rodent management in wheat and rice faring through eco-friendly control techniques is very important in order to address the problem of food grain loss caused by rat.
VPMD has been implementing a project titled ‘Eco-friendly Integrated Rat Management’ in order to address the problem.
He said the project encourages the farmers towards using trap with applying a little amount of rodenticide to control rat in environmental friendly means only when necessary. If this method is practiced properly, about cent percent desired result can be attained.
Alam said a comprehensive approach needs to be adopted to conserve the beneficial insects in the greater interest of maintaining biodiversity and ecological balance.
The new rat control method is helpful to control rat without killing and injuring beneficial animals and insects.
ATM Hasanuzzaman told the farmers that rat is a serious threat to agriculture of the country. It causes wheat damage up to 77,000 tonnes and rice 80,000 tonnes every year. The total loss of rice and wheat may be up to Tk 700 crore. Not only field crop, it causes considerable losses to store products.
He opined that not a single method is effective for rat management. Integration of several techniques can be more effective for rodent control successfully.
Nur-E-Alam Siddiqui said this new rat control method is eco-friendly and farmer can be economically benefited by using the techniques.
Another salient feature of the project is the farmers can control rat successfully in entire field on a community approach basis. This is really a useful and efficient method.
Highly rodent affected farmers of rice and wheat crops can get good results by using the method.
Jahedul Islam says all insects are not harmful for the crops but the chemical pesticides or insecticides are more or less dangerous for both human health and other beneficial insects.
He, however, says the destructive as well as the injurious insects can easily be controlled through promoting the eco- friendly method of using organic fertiliser and indigenous insecticides instead of chemical ones.
