PAU Advisory for Rice Crop

PADDY

1. Give timely and not excessive irrigation for higher yield and stop irrigation two weeks before harvesting.

2. Rogue out the weeds and off type plants from the paddy.

3. Control leaf folder when leaf damage reaches 10 per cent by spraying 20 ml Fame 480 SC (flubendiamide) or 170g Mortar 75 SG (cartap hydrochloride)or one litre of Coroban/Durmet/Force 20 EC (chlorpyriphos) in 100 litres of water per acre.

4. Planthoppers some time become serious in paddy. The crop dries up in patches. The plant hoppers can be controlled by spraying 94 ml Pexalon 10 SC (triflumezopyrim) or 120g Chess 50 WG (pymetrozine) or 40 ml of Confidor/Crocodile 17.8 SL (imidacloprid) or 800 ml of Ekalux/Quinalmass 25 EC (quinalphos) in 100 litres of water per acre. For better results, direct the spray towards the base of the plants.

5. Paddy stem borers cause dead hearts and white erect ears near maturity. In paddy fields showing more than 5% dead hearts, during vegetative stage spray 20 ml Fame 480 SC or 170g Mortar 75 SG or one litre of Coroban/Dursban/Lethal/Chlorguard /Durmat/Classic /Force 20 EC in 100 litres of water/acre. In basmati rice, when 2% dead hearts are noticed these pests can be controlled by applying any of above insecticide or 60 ml Coragen 20 SC (chlorantraniliprole) in 100 litres of water per acre or 4 kg Ferterra 0.4 GR (chlorantraniliprole) or 6 kg Regent/Mortel/Mifpro G/Mahavir GR 0.3 G (fipronil) or 10 kg Padan/Kritap/Sanvex/Caldan/Nidan/Marktap/Miftap 4 G (cartap hydrochloride) or Dursban 10 G (chlorpyriphos) or 4 kg Vibrant 4 GR (thiocyclam hydrogen oxalate) per acre in standing water. Fame 480 SC/ Martar 75 SG/ Coragen 20 SC/Padan / Kritap / Sanvex / Caldan / Nidan / Marktap 4 G Regent / Mortel/Mifpro G/Mahavir GR 0.3 G / Dursban 10 G / Ferterra 0.4 GR or Vibrant 4 GR also control leaf folder effectively.

6. To save the crop from sheath blight, keep the bunds of the fields clean by removing grass. On noticing the disease symptoms spray the crop with Nativo 75 WG @ 80 g or Lustre 37.5 SE @ 320 ml or Amistar Top 325 SC or Tilt/Bumper 25 EC Folicur/Orius 25 EC or Monceren @ 200ml or Bavistin @ 200 g in 200 litres of water per acre. Repeat the spray after 15 days interval.

7. If high humidity and cloudy weather persists, the crop may be sprayed at boot stage with Kocide 46 DF (Chopper hydroxide) @ 500 g in 200 litres of water per acre to control false smut.
