NRRI Scientists team visited the BPH and Leaf Folder affected areas of Odisha
Dr Amaresh Kumar Nayak, Director of ICAR-National Rice Research Institute, Cuttack after receiving the news of Brown Planthopper (BPH) and Bacterial Blight attack/ incidence in paddy fields constituted two scientific teams to visit affected blocks of Balasore and Kendrapara districts. The team comprised of Dr S D Mohapatra, Dr M Chakrabarti, Dr. G P Pandi, Dr. Jeevan B for Balasore and Dr. PC Rath, Dr. A K Mukherjee, Dr. R L Verma for Kendrapara. The teams visited Remuna, Basta and Jaleswar blocks of Balasore district and Mahakalapada, Derabis and Garadpur in Kedrapara district. The Balasore team visited Gopalpur (Remuna), Barunagadia (Basta), Baigan Badia (Jaleswar) and adjoining villages whereas Kendrapara team visited Halabanka (Derabis), Mangalpur (Mahakalapada) and Parakana (Garadpur) villages. The team observed 250-300 BPH nymphs and adults per hill in the basal part of rice varieties Swarna and Kalachampa with hopper burn symptoms in the Gopalpur village. The farmers of the region didn’t take appropriate control measure leading to hopper burn in Remuna block. However, in Jaleswar block the farmers applied the tank mix of two to three pesticides which might lead to resurgence of pests that led to severe leaf folder incidence. There was also severe infestation of leaf folder in Baigan Badia village of Jaleswar Block. However, in all the places in Balasore district, the bacterial blight incidence was low. The farmers have been suggested for routine monitoring of their fields and observe the BPH nymphs/ adults by shaking the hills. Once the population exceeds the ETL level (5-10 nymphs/ adults per hill), apply the recommended doses of insecticides such as triflumezopyrim, pymetrozine, dinetofuran, flunicamide. The farmers have also been suggested to use ricexpert app developed by NRRI for correct identification of insect pests and diseases and follow the recommendations. The team suggested that the spraying should be directed towards the basal portion of the plant for effective control of BPH. Two varieties namely CR Dhan 317 and CR Dhan 805 resistant to Brown Planthopper developed by NRRI were distributed to the farmers of the villages and suggested for multiplication and cultivation in the BPH endemic areas. The team was accompanied by Mr Kamalakanta Behera, SMS (Agril Extension), KVK, Balasore and Assistant Director Agriculture, Assistant District Officer (Agril), Block Agriculture Officer of District Agriculture Department.
