Controlling brown plant hopper (BPH) in paddy with Adama Bazak, Indofil Sky Star
Original: వరిలో సుడిదోమ నివారణ | control of bph brown plant hopper in paddy | adama bazak, indofil sky star
Takeaway
For BPH in paddy at 40-80 DAT use any pymetrozine+dinotefuran/thiamethoxam combo (Rexpect, Sky Star or Bazak) at label dose and avoid heavy urea + dense planting.
Summary
- BPH (Nilaparvata) and WBPH cause 18-30% yield loss in paddy during 40-80 DAT (booting stage), worse in fine-grain than coarse varieties.
- Predisposing factors: excess urea/N, 27-32 deg C daytime, foggy nights, cloudy rain, standing water, close transplanting.
- Option 1: Agrostar Rexpect (Pymetrozine 20% + Thiamethoxam 17.5% + Tebuconazole 12.5% WG) at 160 g/acre also controls leaf spot, sheath blight.
- Option 2: Indofil Sky Star (Dinotefuran 15% + Pymetrozine 45% WG) at 133.2 g/acre.
- Option 3: Adama Bazak (Pymetrozine 29.2% + Dinotefuran 11.7% WG) at 150 g/acre; pick by technical, not brand.
