Pests & Disease Management
Rice Stem Borer

  • For management of Rice Stem Borer:
    • The larvae of these insects bore into the stem and cause damage from July to October.
    • The affected young plants show dead-hearts (yellowing and drying of central shoot) whereas the old ones produce empty ear heads which turn white and stand erect.
    For management,
    • Broadcast Thiamethoxam 1% + Chlorantraniliprole 0.5% GR @ 2500gms per acre at 25 days after transplanting.
    • Foliar spray of Isocycloseram 18.1% w/w SC @ 120 ml per acre or Chlorantraniliprole 9.3% + Lambda-cyhalothrin 4.6% ZC @ 100 ml per acre at 35-40 days after transplanting.
    • Spray Chlorantraniliprole 9.3% + Lambda-cyhalothrin 4.6% ZC @ 100 ml per acre at 60-65 days after transplanting.
    • Further application of any of these insecticides may be repeated as and when damage reaches economic threshold level (5% dead hearts at panicle initiation stage).
    • Prefer neem-based bio-pesticide at pest initiation.
    • Avoid taking ratoon crops.
