Experts have advised against early sowing of paddy nursery, transplanting
Experts from the Punjab Agricultural University (PAU), Ludhiana have advised farmers to be alert about the presence of white backed plant hopper in paddy. The white backed plant hopper transmits the new rice viral disease called ‘Southern Rice Black-streaked Dwarf Virus (SRBSDV).’
This viral disease leads to the problem of stunted/dwarf plants in paddy. PAU experts have warned that since there is no corrective measure for this disease, the only way out is to adopt preventive measures for managing the vector of this viral disease.
To safeguard the interest of paddy farmers, PAU has advised effective management of WBPH. It has advised farmers to regularly monitor the paddy nursery/crop for the presence of WBPH.
A few plants in the field should be slightly tilted and tapped 2-3 times at the base at weekly intervals. WBPH nymphs/adults, if present, will be seen floating on water.
On observing the WBPH in the fields, PAU experts have suggested to spray any of these insecticides: Pexalon 10 SC (triflumezopyrim) @ 94 milliliter per acre or Osheen/Token 20 SG (dinotefuran) @ 80 grams per acre or Chess 50 WG (pymetrozine) @ 120 g per acre. For better results direct the spray towards the base of the plants.
Experts have advised the farmers to follow the transplanting dates recommended by the PAU since stunting was observed to be more in early transplanted paddy in 2022. Farmers should avoid sowing paddy nursery before May 20-25 and its transplanting before June 20-25. It will not only help in managing SRBSDV but also save water, the PAU experts said.
