The maximum relative humidity is expected to remain between 64-86% and minimum between 37-49% during these days.

       If leaf damage in rice by rice leaf folder reaches 10 % (ETL) then spray the crop with 20ml of Fame 480 SC or 170g Mortar 75SG or 350 ml of Marktriazo/Sutathion 40 EC or one litre of Carbon/ Durmet/ Force 20 EC or 560 ml of Monocil 36 SL in 100 litres of water per acre.

If initial symptoms of Parawilt appeared in cotton, spray the affected plants with cobalt chloride @ 1g per 100 litre of water immediately. 

For Ballworms control in desi cotton, the spray should be done when 25 % plants start producing squares and subsequent spray should be done at 10 days interval. In non-Bt cotton spray should be done when Ballworms damage exceeds 5 % among freshly shed fruiting bodies. The crop should be sprayed with Quinalphos 25 EC (Ekalux/GAIG Quinalphos/Quinguard) @ 800 ml/acre or Prophenophos 50 EC (Curacron/Carina/Profex/Celcron) @ 500 ml or Deltamethrin 2.8 EC ( Decs/Rukrain/Dasicare  @ 160 ml or Chlorpyriphos 20 EC ( Coroban/Dursban/Durmet/Radar/Lethal/Chlorguard/Force) or Spinosad 48 SC (Tracer) @ 60 ml or Indoxacarb 15 SC (Avaunt) m@ 200 ml or Chlorantraniliprolr 18.5 SL (Coragen) @ 60 ml per acre using 125-150 litres of water.

The weed infestation is major problem during rainy season. To control weeds apply post emergence application of Glycel 41 SL or Gramaxone 24 WSC @ 1.6 liters per acre in 200 liters of water during this season. Avoid drift of weedicide on fruit plant parts.
