Advisory related to Cotton & Rice

Cotton: In view of rainfall, apply only need based irrigation to cotton crop. Apply remaining half dose of nitrogen at flowering stage.

• Monitor the crop regularly for whitefly attack and spray should be done when population reaches 6 adults/leaf in the upper canopy of the plant before 10 AM.

Initiate spray against jassid when ever some of the fully formed leaves in the upper canopy show yellowing and curling at the margins on 50 percent on the plants. Use Keefun 15EC (tolfenpyrad) @ 300ml/acre or Ulala 50 WG (flonicamid) @ 80 g/acre or Osheen 20 SG (dinotefuran) or Imidacel 17.8 SL/Confidence 555/Confidor 200 SL (imidacloprid) @ 40 ml/acre in 125-150 litres of water.

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.

Rice stem borers: 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 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. Rogue out and destroy foot rot infected plants from the field.
