PAU Advisory for Rice Crop

Rice: Apply irrigation to paddy crop, two days after the ponded water has infiltrated into the soil. Care should be taken that the field does not develop cracks.

• The larvae of stem borer 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 earheads which turn white and stand erect. The fields showing more than 5% dead hearts (Economic Threshold Level, ETL) should be sprayed with 20 ml Fame 480 SC (flubendiamide)* or 170 g of Mortar 75 SG (cartap hydrochloride) or 1 litre of Coroban/Dursban/Lethal/Chlorguard/Durmet/Classic/ Force 20 EC (chlorpyriphos) in 100 litres of water per acre. Further application of any of these insecticides may be repeated as and when damage reaches economic threshold level.
• To save the rice crop from sheath blight, keep the bunds of the field clean by removing grasses. If the symptoms of disease observed, spray Nativo @80 g or Amitsar Top/Tilt/Folicur/Pikapika@200ml in 200 litres of water per acre. Direct the spray towards the base of crop.
• To control False smut, give spray of 500 g Kocide in 200 litres of water per acre at boot stage of the crop in disease prone areas.
• To the basmati crop, apply urea in two equal splits at 3 and 6 weeks after transplanting.
• Rogue out and destroy foot rot infected plants from the field.
