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 the field with Chlorantraniliprole 0.4% GR @4kg/acre at 15-25 days after transplanting.
• Foliar spray of Deltamethrin 11% w/w SC @ 60-75 ml per acre at 30-40 days after transplanting followed by Chlorantraniliprole 18.5% w/w SC @ 60 ml per acre or Flubendiamide 20% WDG 80 ml @ 60 gms per acre at 45-50 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.
